    [0001] FIELD OF THE INVENTION The present invention relates to a roll incorporating a motor having a power transmission member. The invention also relates to any of the components of the roller incorporating a motor and more particularly to the power transmission member between the motor and the roller. STATE OF THE ART A roller incorporating a motor as a component of a roller conveyor or the like is known. The roller incorporating a motor comprises a motor and a gearbox housed in the body of the roller and rotating the body, outer side by the engine, inner side. More specifically, the roller incorporating a motor or power unit has a power transmission member for transmitting power from the motor to the roller body; this transmission member transmits the rotational force of the motor to the roller body. As a remark, most of the power transmission members used to transmit power to a roll body are traditionally configured to be integrally fixed in the inner wall of the roll body to make this transmission efficient, easy to manufacture as described, for example, in US 7,207,433. A method of closely fitting the power transmitting member in the roll body is known in the conventional manner as a method of attaching a power transmission member to a roll body. In such an arrangement, the transmission member that is not attached to the roller body or its capacity for transmitting power to the roller body may be insufficient because of the differences in the manufacture of the roller body and in particular the variations thereof. nations of internal diameters of the roll body. Indeed, if the inside diameter of the roll body is too large, the contact force between the roll body and the power transmission member is not sufficient since the friction forces do not connect the roll body and the power transmission member which will rotate freely in the roll body.
    [0002] In other words, to generate an appropriate frictional force between the roll body and the transmission member, the inner peripheral surface of the roll body and the outer peripheral surface of the transmission member of the power are accurately machined. The outer diameter of the power transmission member should be slightly greater than the inside diameter of the roll body. However, even if the outer diameter of the transmission member is machined to the appropriate size for the inside diameter of the roll body, the frictional forces between the roll body and the transmission member decrease because of the aging and can be rotated relative to one another during operation of the roller incorporating a motor. In addition, while the roll body may have certain manufacturing defects, and especially variations in the inside diameters of each roll body, the drive shaft of the roll incorporating the motor is at the center of the roll body. ; the power transmission member must be placed in the center of the roller body which itself must be aligned with the drive shaft. The center of the power transmission member must be aligned with the center of each roll body to compensate for roll bodies whose inner diameter may vary. OBJECT OF THE INVENTION The object of the present invention is to develop a motor-integrating roll avoiding the difficulties of the state of the art, to develop a power transmission member which can be fixed firmly to the roll body and whose center is aligned with the center of the roll body even if there are manufacturing differences affecting the roll body.
    [0003] The invention also aims generally to develop a roller incorporating a motor and having such a power transmission member. DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the subject of the present invention is a roller 35 incorporating a motor and having a hollow body, a power unit with a motor, and a power transmission member. the power unit and the power transmission member 5 being connected in the roll body, the rotational force of the drive unit being transmitted to the roll body by the power transmitting member, the power transmission having - a connecting member with an annular portion whose outer circumferential surface is partially or wholly provided with arcuate portions and the inner circumferential surface having concave-convex portions, - an elastic intermediate member, and an engagement member with an outer engagement portion and an inner engaging portion; the connecting member, the intermediate member and the engagement member being distinct from the rim body; water, and - the arcuate portion of the outer peripheral surface of the connecting member being in contact with the inner peripheral surface of the roll body and the connecting member is fixed in the roll body by a fastening means which is one of the following fastening means: binding, welding, fastening element and mechanical engagement obtained by matting the roll body, the intermediate member engages in the concave-convex portion of the connecting member and the outer engagement portion of the engagement member holds the inner engaging portion of the engagement member in the center of the roll body, and - the driving unit cooperates with the engaging portion. internal commitment of the commitment body.
    [0004] Thus, according to the invention, the power of the power unit is transmitted integrally from the connecting member of the power transmission member to the hollow body of the roll by the fastening means which is at least one the following means: bonding, bonding, welding, fixing element and mechanical engagement obtained by molding or crimping the roll body, independently of the friction.
    [0005] The fastening element is a rivet, a spindle, a screw or a mechanical connection means of this type. According to the invention, since the inner peripheral surface of the annular portion of the connecting member has a convex / convex portion, the engagement member has an outer engagement portion and the intermediate member engages with the concave / convex portion of the connecting member, the outer engagement portion of the engagement member, the connecting member and the intermediate member and the engagement member of the member the power transmission being thus locked in rotation relative to one another. Similarly, as the power unit or power unit cooperates with the inner engagement portion of the engagement member, it transmits the power to the transmission member.
    [0006] Thus, when the power unit transmits the power to the engagement member, the connecting member, the intermediate member and the engagement member rotate integrally. The arcuate portion of the outer peripheral surface of the connector member is in contact with the inner peripheral surface of the roller body and the connecting member is integrally attached to the roller body by mechanical engagement. obtained by caulking or crimping the roll body and / or fastener so that the power is transmitted integrally to the roll body by the power transmitting member when the drive unit is operating and the roll body turned. As the connecting member and the roller body are fixed integrally to each other, they can rotate relative to each other, which ensures the integral transmission of power between these two bodies. The intermediate member is resilient and cooperates with the concave / convex portion of the connection member and the outer engagement portion of the engagement member, the inner engagement portion of the engagement member being held in the center of the roll body so that the inner engaging portion is engaged in the engagement member with the drive unit. In other words, if the center of the roll body and the center of the power transmission member do not coincide, the intermediate member deforms elastically and compensates for the misalignment so that the portion Inner engagement of the engagement member may be engaged in the drive unit to align the center of the power transmission member and the center of the roll body. The connecting member is preferably deformable. In particular, the connection member can contract radially. According to one development, the deformability of the connecting member enables it to easily adapt to the inner peripheral surface of the hollow body of the roll. This means that if the inside diameter of the roll body is smaller than that of the connecting member, the connecting member can deform and penetrate into the roll body. Preferably, the annular portion of the connecting member has a set of arcuate portions which are located in different positions at the peripheral surface and a plurality of recessed portions, each is radially recessed towards the interior from the annular portion, the arcuate portions adjacent to each other being connected by recessed portions.
    [0007] According to a development, the connecting member is pressed against the inner surface of the hollow body of the roll and the recesses deformed so that the arcuate portions are brought closer to each other and allow to easily reduce the diameter of the connecting member to accommodate it in the roll body.

The roller body and the connecting member are easily assembled by the fastening means. The annular adjacent inner protruding portion 5 is an inwardly facing flange which increases the rigidity of the entire connector member. Preferably, the annular portion of the connecting member has a set of arcuate portions provided with an inner wall adjacent to the arcuate portion at the axial end thereof. part of the wall is turned radially inwards and all of the recessed portions having no inner wall or an inner wall smaller than that of the arcuate portions, these arcuate portions and the recessed portions being connected in the annular direction.
    [0010] According to this development, the elasticity of the recessed portion is different from that of the arcuate portion. In other words, the elasticity of the recessed portion is less than that of the arcuate portion. As a result, when the diameter of the annular portion is reduced by compression, the arc-shaped portion retains its shape and the recessed portion deforms. Thus, the arc shape ensures close contact with the roll body when the connecting member is introduced into the roll body. Preferably, the annular portion of the connecting member has a set of arcuate portions and a set of recessed portions, the latter being more easily elastically deformable than the arcuate portions of so that the arc-shaped portions, that is to say the raised portions and the recessed portions are connected in the annular direction. According to one development, the arc shape ensures close contact with the roll body when the connecting member is housed in the roll body. Preferably, the annular portion of the connection member has a set of arc-shaped portions (raised portion) and a set of recessed portions, the arcuate raised portions and the parts thereof. recessed being connected in the annular direction and the recessed portions having an arcuate shape.

DESCRIPTION OF EMBODIMENTS One embodiment of a roller incorporating a motor 20 according to the invention will be described hereinafter. The roller incorporating a motor 1 according to the present embodiment is characterized by a power transmission member for transmitting the driving force of a motor 12 to a roll body 11. The description will begin with that of the basic structure 25 of the roller 1. According to Figures 1 to 3, the basic structure of the roller incorporating a motor 1 comprises a roll body 11, cylindrical, hollow and plugs 41, 42; it receives a power unit with a geared motor 22 formed of a motor 12 and a gearbox 13. In the embodiment, the motor 12, the gearbox 13 and the circuit board 42 are integrated in a power unit 3, housed in the roller body 11. The geared motor 22 is part of the power unit 3. The roller body 11 is a cylinder with both ends open. The plugs 41 and 42 are attached to the roll body 11 to cover both ends. As shown in FIG. 2, the cover 11 (on the left-hand side of FIG. 2) consists of the combination of a packing 52, a bearing 54 and a shaft member 53, on the body side. The other plug 42 (on the right side of FIG. 2) has a combined packing 55, roller side and a bearing 56.
    [0016] The body-side member 53 has a section of which a portion or the whole is not circular. In this embodiment, the section is generally hexagonal. As shown in FIGS. 2 to 4, the power unit 3 has a cylindrical housing 44, housing the motor 12, the gearbox 13 and the circuit board 43. The housing 44 has a fixed axis 45, which comes into the air. - Link an axial end and an axis, drive side 46 (motor unit) out of the other axial end. The fixed-side axis 45 is an axis housed in the bearing 56 of the cover 42, the driving unit 3 being housed in the roll body 11; This axis constitutes the axis, body side of the roll body 11. The axis, drive side 46 is connected to a power transmission element 2 described hereinafter; the driving unit 3 is housed in the roller body 11 constituting the axis of rotation which outputs the power of the drive unit 22 to the roller body 11.
    [0017] It should be noted that both the axle, fixed side 45 and the axis, drive side 46 both have a substantially hexagonal section. The description below relates to the power transmission element 5 according to the invention. The power transmission element 2 according to the embodiment shown is an element housed in the body 11 of the roll 1 incorporating a motor; this transmission element transmits the power of the motor 12 to the roller body 11. For this function, the power transmission element 2 has a concave / convex member 4 (connecting member), an intermediate member 5 and a engagement member 6 as shown in Figure 5 and Figures 6A-6B. The concave / convex member 4 is made of a rigid metal such as steel, zinc or aluminum. The concave / convex member 4 is a hollow, annular or cylindrical member. The convex / convex member 4 has a radially projecting portion and a radially recessed portion. In a detailed manner, the concave / convex member 4 comprises a set of projecting portions 7 in the shape of an arc of a circle, cavities 8 radially recessed and parts in internal projection 9. In this embodiment, the organ concave / convex 4 has four arcuate projecting parts 7, four recessed portions 8 and four internally projecting portions 9. The outer periphery of the arcuate projection portion 7 has a concave / convex arc-shaped surface. The outer periphery of the recessed portion 8 has an arcuate inner convex surface. The arcuate projecting portion 7 is a radially protruding portion of the concave / convex annular member 4. The outer periphery of the arcuate projection portion 7 has a curved surface which radially the outside with a convex shape. The arcuate projections 7 are in four positions at the periphery of the concave / convex member 4. While the arcuate projections 7 are preferably located on the same periphery, In some cases, there may be manufacturing defects. The inner periphery of the arcuate projecting portion 7 provides a concave curved surface 16. The thickness, i.e., the distance between the outer peripheral surface and the inner circumferential surface of the portion arc-shaped projection 7 is thin, allowing the passage of a rivet 25 35. The cavity portions 8 are adjacent to the arcuate protruding portions 7 on both peripheral sides of the concave member / The projecting portion 8 is a recessed portion on the outer peripheral side of the annular concave / convex member 4; the cavity portions 8 occupy four positions at the periphery of the concave / convex member 4. The outer periphery of the recessed portion 8 has a curved concave surface. This means that the recessed portion 8 is radially recessed with respect to the arcuate protruding portion 7.
    [0018] The inner peripheral surface of the recessed portion 8 is radially inwardly projecting and forms a convex surface 18 on the inner peripheral side of the concave / convex member 4. The arcuate protruding portions 7 and the hollow portions 8 alternate in the circumferential direction by being adjacent, thereby forming an annular portion 15. The concave / convex member 4 has a structure radially outwardly projecting from the projections arcuate 7 and radially recessed inwardly at the recessed portions 8. The concave surface 16 and the inner peripheral surface of the arcuate projection portion 7 adjacent to the convex surface 18 which is the inner peripheral surface of the recessed portion 8, in the concave / convex member 8, thus form a concave / convex portion 19.
    [0019] The inner projecting portion 9 is a plate-shaped portion adjacent to the arcuate projection 7. In the embodiment, the inner protruding portion 9 is adjacent to the arc-shaped portion. 7 and extends radially inwardly to form an inner wall.
    [0020] The inner wall at the axial end of the arcuate projection 7 is adjacent to this portion 7 and radially inwardly oriented. The surface of the inner projecting portion 9 intersects the surface forming the arcuate projecting portion 7 and extends radially inwardly of the concave / convex member 4 at one end of the housing. The inner projecting portions 9 are at the same end of the arcuate portions 7. Thus, each inner projecting portion 9 is configured in that a set of sections (four sections ) of the inner annular flange are cut off radially. In other words, the inner projecting portions 9 have such a structure that the inwardly facing annular flange has a set of radial slots. The inner projecting portion 9 functions as a rib reinforcing the arcuate projecting portion 7. The arcuate projection portion 7 thus may deform less under the effect of an external force exerted. in the radial inner direction on the protruding portion 7. Furthermore, since the recessed portion 8 does not have elements corresponding to the inner projecting portion 9, the recessed portion 8 may undergo elastic deformation if compares it to the arc-shaped projection portion 7. The concave / convex member 4 has an annular configuration; it is formed as a thin-walled member whose inner side of the annular portion 15 has a region R1 for receiving the intermediate member. The concave / convex portion 19 described above corresponds to the region R1 receiving the intermediate member. The intermediate member 5 described below is made of an elastic material such as rubber; it is a short cylindrical piece of annular configuration such as that shown in FIGS. 6A and 6B. The outer shape of the intermediate member 5 is substantially similar to the contour of the region R1 receiving the intermediate member of the concave / convex member 4; it is slightly smaller than that of the region R1 receiving the intermediate member. The dimension of the intermediate member 5 allows it to be housed in the receiving region R1 of the intermediate member of the concave / convex member 4. The intermediate member 5 has protruding parts 25 and parts 26. Thus, the intermediate member 5 has projecting portions 25 radially projecting in a plurality of positions (four positions) of the periphery and the recessed portions 26 which are radially recessed in a plurality of positions (four positions) of the periphery. The protruding portion 25 radially projects from the outer peripheral surface of the intermediate member 5 in an annular form. As shown in Figs. 6A-6B, the projecting portion 25 has a groove 27. The groove 27 is oriented in the width direction of the intermediate member 5. The inner peripheral side of the projecting portion 25 of the intermediate member 5 has a concave portion 28.
    [0021] The recessed portion 26 is radially recessed relative to the outer peripheral surface of the annular intermediate member 5. The outer surface of the recessed portion 26 is concave. The recessed portion 26 connects the projecting portions 25 adjacent to each recess 26. The inner peripheral side of the recess 26 of the intermediate member 5 has a convex portion 29 radially inwardly projecting. The interior of the annular intermediate member 5 has a region R2 for receiving the engagement member. This region is defined by the concave portions 28 and the convex portions 29. The region R2 receiving the engagement member provides an inner engagement portion of the intermediate member 5. The receiving region R2 of the engagement member may be enlarged when an external force is applied. The projections 25 and the recesses 26 of the intermediate member 5 constitute the outer engagement portion. The outer shape of the intermediate member 5 is substantially similar to the space of the receiving region R1 of the intermediate member of the concave / convex member 4. The intermediate member 5 has dimensions slightly smaller than those of the R1 region receiving the intermediate member. The engagement member 6 described hereinafter is a piece of a rigid metal such as steel, zinc or aluminum. The width of the engagement member 6 is such that it can be accommodated in the region R2 provided for receiving the engagement member in the intermediate member 5. The engagement member 6 is composed of a main body 30, cylindrical and four protruding portions 31 (outer engagement portions). The cylindrical main body 30 has a cylindrical portion, the inside of which has a housing 32 for the insertion of the shaft (inner engaging portion). The insertion housing of the axis 32 is a polygonal section hole (generally a hexagonal hole). The projecting portion 31 is a rectangular prismatic portion which is integral with the outer circumferential surface of the cylindrical main body 30 and extends radially outwardly. In the embodiment, there are four projecting portions 31 attached to the outer peripheral surface 30 of the main body 30 in equiangular positions. The appearance of the engagement member 6 is substantially similar to that of the region R2 for receiving the engagement member 5 in the intermediate member 5. The engagement member 6 has dimensions slightly less than the free space of the region R2 intended to receive the engagement member. The power transmission member 2 is produced by the combination of the concave / convex member 4, the intermediate member 5 10 and the engagement member 6. Thus, the intermediate member 5 is inserted into the region R1 provided to receive it in the concave / convex member 4; the engagement member 6 is housed tightly in the region R2 of the intermediate member 5. The intermediate member 5 is elastically deformable, which allows to introduce it into the region R1 intended to receive it in the concave / convex member 4 by elastic deformation. While the engagement member 6 is rigid, the monitoring of the inner wall of the intermediate member 5 which forms the region R2 for receiving the engagement member is resiliently deformable. Thus, the engagement member 6 is tightly accommodated in the region R2 by expansion of the inner portion of the intermediate member 5. As the intermediate member 5 is of slightly smaller dimensions than those of the region R1 intended to receive it, according to the embodiment example above, the intermediate member 5 is introduced gently into the region R1 which receives it in the concave / convex member 4. Alternatively, the intermediate member 5 can be engaged by a tightening adjusted in the region R1 of the concave / convex member 4, the intermediate member 5 having dimensions slightly greater than those of the region R1, intended to receive it. The concave / convex member 4, the intermediate member 5 and the engagement member 6 of the power transmission member 2 have an annular shape; the engagement member 6 is mounted in the concave / convex member 4 by the intermediate member 5. Accordingly, the center of the axle insertion hole 32 of the engagement member 6 can To be offset slightly by eccentric deformation of the intermediate member 5. In other words, if the center of the axis insertion hole 32 of the engagement member 6 and the center of the roller body 11 (ie the center of rotation of the axis, driving side 46) do not coincide in the absence of external force applied to the intermediate member 5, the elastic deformation of the intermediate member 5 subjected to an external force, moves the position of the engagement member 6 thus aligning the center of the axis insertion hole 32 10 of the engagement member 6 and the direction of rotation of the axis, driving side 46. The axis, drive side 46 placed in the center of the roll body 11, is introduced into the insertion hole of The description given below relates to the operation of fixing the power transmission member 2 to the body 11 of the roll. According to FIGS. 7A and 15A, the concave / convex member 4, the intermediate member 5 and the engagement member 6 forming the power transmission member 2 are separate elements, i.e. that they are not combined with each other. In the first place, only the concave / convex member 4 is placed in the desired position in the roll body 11. The desired position in the roll body 11 is the position of the axis, drive side 46 (power unit Figure 1. The axis, drive side 46, is not shown in Figures 11A-11C for simplification purposes. It is assumed that the outer diameter of the convex / convex member 4 is slightly greater than the inside diameter of the roll body 11 so that the concave / convex member 4 deforms and penetrates into the roll body 11. concave / convex member 4 has arcuate projecting portions 7 and recessed portions 8; when the arcuate protruding portions 7 are pressed against the inner peripheral surface 1a of the roller body 11, the recessed portions 8 deform and the projecting portions 7 move closer to each other 3035459 thereby reducing the diameter of the concave / convex member 4. In other words, the arcuate projecting portions 7 radially fit. Although the material of the concave / convex member 4 is a rigid material such as a metal, the arcuate projections 7 and the recessed portions 8 allow the concave / convex member 4 to distort slightly. However, since the recessed portions 8 are easily deformed, in contrast to the arcuate projections 7, the concave / convex member 4 decreases in diameter while retaining the shape of the protruding portions 7 and settles thereon. in the inner peripheral surface 1a of the roller body 11. The arcuate projection portion 7 retains the shape corresponding to that of the inner peripheral surface 1a of the roller body 11 in this embodiment so that the The arcuate protruding portions 7 come into close contact with the inner peripheral surface 1a of the roller body 11. The concave / convex member 4 thus fits in the roll body by radial compression. According to FIGS. 7B and 15B, once the convex / convex member 4 is installed at the desired position of the roll body 11, the concave / convex member 4 attaches to the roll body 11 by the rivet 35. (fastener) shown in Figure 17A. The rivet 35 will be described below. According to FIG. 17A, the rivet 35 has a mushroom head 35a and a cylindrical rod 35b. The inside of the rod 35b has a hollow 37. The end of the rod 35b has an orifice communicating with the internal volume 37. Thus, the end of the rod 35b has an edge 40 surrounding the annular opening. Rivet 35 may be a self-piercing rivet of FUKUI BYORA Co., Ltd .; it is made of a material such as carbon steel, stainless steel or aluminum. The rivet 35 connects two elements using a template 36a. The template 36a has a support surface 34. The support surface 34 is flat or curved and corresponds to the concave surface 16 of the inner peripheral surface of the arcuate shaped portion 7 of the concave member 4. The support surface 34 has a non-through hole 48. The center of the non-through hole 48 is provided with a projection 49. The projection 49 has a particular shape such as a cone. The section diameter of the connection portion between the projection 498 and the blind bore 48 is larger than the inside diameter of the rod 35b. Thus, as shown in FIG. 18A, the gap 37 is aligned with the end of the projection 49, the edge 40 of the gap 37 of the pin 35b of the rivet 35 being opposite the end of the projection 49 of the template 36a. When the head 35a of the rivet 35 is struck with a hammer or the like tool, not shown, the rod 35b of the rivet 35 enters the body 11 of the roll and digs the concave / convex member 4 as shown in FIG. 18B . The edge 40 of the rod 35b is then pressed against the base end of the projection 49, larger than the inside diameter of the rod 35b through the concave / convex member 4. The pin 35b of the rivet 35 is thus open and unfolds as shown in Figures 18C-18D. The rivet 35 which penetrates into the roll body 11 and into the concave / convex member 4 thus makes it possible to assemble them using a template 36b like that of FIG. 17B. The jig 36b has a structure with a blind hole central portion 39 formed in a flat plate provided with a substantially conical projection 39. According to FIG. 19A, the template 36b is placed against the inner peripheral side of the concave / convex member 4 and the rivet 35 on the outer side of the roll body 11. The center of the rod 35b of the rivet 35 is aligned with the projection 39 of the template 36b. When the head 35a of the rivet 35 is struck with a hammer, the rivet 35 enters the roll body 11 and the concave / convex member 4 as shown in Fig. 19B.
    [0022] As shown in FIGS. 19C-19D, the rod 35b of the ridge 35 comes into the terminal bore 38 and the projection 39 of the jig 36b so that the rod 35b of the rivet 35 opens and its end deploys into the piercing terminal 38; the open shank 35b meets the concave surface 16 (i.e., the inner peripheral surface) of the convex / convex member 16. The head 35a of the rivet 35 encounters the outer peripheral surface of the Thus, the roll body 11 and the concave / convex member 4 are held together by the head 35a and the open shank 35b of the rivet 35. In return to FIG. 7B, it is seen that the roll body 5 11 and the projecting arc-shaped portion of the concave-convex member 4, are assembled by the rivet 35. For this purpose, the template 36a is placed in the region R1 intended to receive the intermediate member in support against the concave surface 16 of the concave-convex member 4 and the rivet 35 is placed opposite to the outer side of the roll body 11. When the head 35a of the rivet 35 is struck with a hammer, not shown the end of the pin 35b of the rivet 35 penetrates the roll body 11 and enters the body member ncave-convex 4 (arcuate projecting portion 7). Then the end of the rod 35b opens into the concave-convex member 4 (arc-shaped projection portion 7) to expand so that the roll body 11 and the concave-convex member 4 are assembled as shown in FIGS. 7C and 15C. Alternatively, the roller body 11 and the arc-shaped projecting portion 7 of the concave-convex member 4 are fixed with the rivet 35 as shown in FIG. 11B. In this case, the template 36b is placed in the region R1 intended to receive the intermediate member, bearing against the concave surface 16 of the concave-convex member 4; the rivet 35 is placed opposite to the outside of the roll body 11. When the head 35a of the rivet 35 is struck with a hammer or a similar tool (not shown) the rod 35b of the rivet 35 enters the body 11 and 25 in the concave-convex member 4 (arcuate projection portion 7); the end of the rod 35b meets the template 36b and opens. As a result, the end of the rod 35b extends laterally into the terminal bore 38 of the jig 36b; the head 35a of the rivet 35 comes into close contact with the roll body 11 and the open portion of the rod 35b arches in close contact with the inner peripheral surface of the arcuate portion 7 of the concave member -convex 4. Thus, the roll body 11 and the concave-convex member 4 are assembled as shown in Figure 11C.
    [0023] Then, the intermediate member 5 is installed in the concave-convex member 4 thus fixed to the roll body 11, as follows from FIGS. 7A-7C or 11A-11C. The outer diameter of the intermediate member 5 is smaller than the inner diameter of the roll body 11, as shown in Figs. 8A or 12A. Thus, the intermediate member 5 can simply penetrate the roll body 11 and be placed in the concave-convex member 4. The intermediate member 5 is introduced into the region R1 10 intended to receive it in the concave-convex member 4 as shown in Figures 8B or 12B. The intermediate member 5 is placed in the region R1 which receives it by elastic deformation. The projecting portions 25 and the recesses 26 of the intermediate member 5 shown in FIGS. 6A-6B come into close contact with the concave surfaces 16 and the corresponding convex surfaces 18 of the respective concave-convex member 4. . Consequently, the concave-convex member 4 and the intermediate member 5 are engaged by a concave-convex connection and these two members can not rotate relative to each other. The projecting portion 25 of the intermediate member 5 having a groove 27, the projecting portion 25 is elastically deformed, which reduces the width of the groove 27. According to FIG. 10B, the alignment of the groove 27 on the position of the rivet 35 prevents the intermediate member 5 from reaching the rivet 35 or the concave-convex member 4 is depressed by the rivet 35; this facilitates the installation of the intermediate member 5 25 in the concave-convex member 4. The intermediate member 5 which has entered the region R1 intended to receive it, abuts against the inner projection 9 of this concave-convex member 4 who stops him; it is thus blocked in the region R1 as shown in FIGS. 8C or 12C.
    [0024] Finally, the engagement member 6 is installed in the region R2 for receiving it in the intermediate member 5 as shown in FIGS. 8A-8C or 12A-12C. Since the outer diameter of the engagement member 6 is smaller than the inside diameter of the roll body 11, as shown in FIGS. 9A-13A and 16A, the engagement member 6 can easily move in the roll body 11 and arrive quickly in the position of the intermediate member 5. The engagement member 6 is then tightened in the region R2 intended to receive it in the intermediate member 5 5 as the shows Figures 9B-13B. At this time, the intermediate member 5 undergoes an elastic deformation and the engagement member 6 is placed in the region R2 intended to receive it as shown in Figures 9C-13C and 16B. The protruding parts 31 of the engagement engagement 6 10 come into the corresponding concave portions 28 of the intermediate member 5. Thus, the engagement member 6 and the intermediate member 5 are locked in rotation. one with respect to the other. The concave-convex member 4 receives the elastically deformable intermediate member 5, which allows the position of the engagement member 6 to be accurately adjusted. In other words, the elastic deformation of the intermediate member 5 allows to move the position of the engagement member 6. Precisely, even if the center of the power transmission member 2 is attached to the roll body 11 does not coincide with the center of the roll body 11 in Under normal conditions, the drive-side axis 46 (output axis) can be introduced into the axis insertion port 32 of the engagement member 6 as shown in FIGS. 10A and 14. by elastic deformation of the intermediate member 5. The axis, drive side 46 hexagonal section, 25 is introduced into the axis insertion hole 32 which is a hexagonal section of the hole so that the axis is blocked with respect to the orifice. The attachment structure of the power transmission member 2 and the roll body 11 is as follows. The intermediate member 5 fits into the concave-convex member 4 (the region R1 receiving the intermediate member) and the intermediate member 5 and the concave-convex member 4 are locked in rotation. compared to each other. The engagement member 6 then lodges in the intermediate member 5 (in the region R2 receiving the engagement member), although the engagement member 6 and the intermediate member 5 are thus blocked. in rotation with respect to each other. In addition, the roller body 11 and the four arc-shaped projections 7 of the concave-convex member 4 are secured by rivets 35 so that the roller body 11 and the transmission member power 2 are secured to one another and can not rotate relative to each other. It should be noted that if the roller body 11 and at least one arcuate projecting portion 7 are secured by a rivet 35, the roller body 11 and the concave convex member 4 can not rotate. one compared to the other. Since the engagement member 6 and the roller body 11 can not rotate relative to each other, the rotational force of the gear motor 22 is transmitted to the roller body 11 by the engagement member. 6, the intermediate member 5 and the concave-convex member 4.
    [0025] When the drive shaft 46 of the gear motor 22 rotates, the roller body 11 rotates as well. The power transmission member 2 and the roll body 11 are integrally connected by the rivets 35, according to the embodiment described above, but it is also possible to connect the roll body 11 and the concave body. convex 4 of the power transmission member 2 using a mechanical connection. Thus, Figs. 20A-20B show crimped portions 60 made by strongly striking precise portions of the roller body 11. The crimped portions 60 partially dig out the arcuate protruding portions 7 of the concave-convex member 25 4 of the power transmission member 2. The roller body 11 and the concave-convex member 4 are thus secured in rotation. The power transmission member 2 is firmly attached to the roll body 11 as described above so that the power transmission member 2 is integral with the roll body 11 as compared with a method of the invention. fixing using friction. In addition, even if there is a difference in the inside diameter of the roll body 11, due to a manufacturing defect, the roll body 11 and the power transmission member 2 are firmly closed. secured by the rivets 35 (fasteners) or by matting (mechanical connection). Under these conditions, even if the center of the roll body 11 and the center of the power transmission member 2, (i.e., the center of the axis insertion port 32 of the member 5 of engagement 6) do not coincide, the elastic deformation of the intermediate member 5 aligns the center of the insertion hole of axis 32 of the engagement member 6 and the center of the body The power transmitting members 2 and 62 (i.e., the concave-convex member 4 and the connecting member 64) can be attached to the roll body 11 by a bonding connection. or welding in place of rivet 35 (fastener) or matting or crimping (mechanical bonding) as described above. This means that the inner peripheral surface 11a of the roll body 11 and the concave-convex member 4 (connecting member) of the power transmission member 2 or the connecting member 64 of the body Power transmission 62 can be joined by a bonded connection or by spot welding. The roller body 11 and the power transmission member 2, 62 (i.e., the concave-convex member 4 and the connecting member 64) can be attached to one another in combining two assemblies such as bonding, welding, a fastener or a mechanical connection, with the power transmission members 2, 62 and the roll body 11. In place of the concave member, 4 (connecting member) of the power transmission member 2 of FIGS. 6A and 6B, a connection member 64 of the power transmission member 62 can be used as shown in FIG. The power transmission member 62 comprises a connection member 64, an intermediate member 5 and an engagement member 6. The intermediate member 5 and the engagement member 6 of the transmission member power 62 are the same as the intermediate member 5 and the engagement member 6 of the power transmission member 2 The connecting member 64 has a structure substantially identical to that of the concave-convex member 4 and the same elements 35 have the same references; their description will not be repeated.
    [0026] The connecting member 64 has a flange 69 such that the inner projecting portions 9 adjacent to each other and continuous, unlike the inner projecting portions 9 of the concave-convex member 4. The flange 69 is an inwardly-facing flange provided with a port 69a; it is formed around the entire periphery of the annular portion 15 of the connecting member 64. The outer peripheral portion of the flange 69 is adjacent to the annular portion 15 around the entire periphery. As the flange 69 increases the rigidity of the connection member 64, it is less deformable when an external force 10 is exerted radially on it. Since the outer peripheral portion of the flange 69 is adjacent to the annular portion 15 over the entire periphery, the flange 69 will not deform if a force is exerted in the normal direction on the flange 69. Thus, even if the intermediate member 5 is pressed and a load is applied in the normal direction on the flange 69, once the intermediate member 5 housed in the region R1 to receive it, the flange 69 will not deform, if the intermediate member 5 is blocked in the region R1 which receives it.
