    ROLLING PART FOR A SEGMENT ROLLER
    The subject of the invention is a roller part for a segment roller, in particular a roller part for a segment roller according to claim 1.
    According to the art, a segment roller is known to comprise a plurality of successively positioned roller parts, with which the curvature of such a segment roller can be adjusted if appropriate by changing the position of the support point on the individual roller parts and / or the removal of a mounting pad, which is why the roller in the For example, in connection with a treatment of web-like material, it is well suited as a lathe-stretching roller. The segment roller can also be used, for example, as a guide roll for a fiber web or as a pressure roll during winding. In these and many other applications, the segment roller is usually used as a straight roll without Krüm¬mungsverstellung.
    In the known segment rollers, each roller member is generally mounted at its two ends to the mounting pad or to a corresponding support structure. Oftentimes, roller parts have a common bearing with two juxtaposed roller parts. The removal of a single roll member from the center of such a segment roller can be difficult since the disassembly of the roll members from one of the two ends of the roll must be started so that the roll member located in the center of the segment roll can be changed.
    From the publication Fl 62514 B is a similar spreader roller as the vorste¬hend shown known, in which a respective two-part support bearing is arranged for the corresponding axis parts of the adjacent roller parts, which determines the degree of curvature. At each axis part a separate support bearing is arranged, which is formed as Gelenkla¬gerstelle. The hinge bearings of the juxtaposed axle members are mounted adjacent to each other on the opposite side of the support bearing, each support bearing member carrying one of the adjacent hinge bearings. A two-piece support bearing allows removal and mounting of a single roll part without having to disassemble the entire spreader roll. On the other hand, two bending axes which are located at a small distance from one another are formed between two adjacent roller parts, which results in the roller not bending uniformly. If the bending axis is not located in an interface between the parts of the roll, but at a small distance therefrom, turning the roll raises the end of the roll shell and the roll is toothed. Here, the curl of the roll is not geometric, which causes problems in the control of the fibrous web.
    In the patent publication Fl 106277 B a segmented roller is shown, which comprises several successively positioned roller parts, each of which is rotatably mounted on a eige¬nen support axis. According to the publication, connecting elements are arranged on both axial end surfaces of the support axis on the roller parts for the segment roller, with the aid of which two successive roller parts can be detachably coupled to one another. The support shaft is composed of at least two parts whose mutually variable position makes it possible to change the axial length of the support shaft. Here, the bending axis located between two juxtaposed roller parts is arranged between their interfaces, as a result of which the roller bends uniformly and no toothing is formed between the roller parts; thus, the construction of the roller is advantageous in this respect. Here, the roller member is constituted by an outer cylinder and an inner cylinder or cylinder-like bushes connecting a radial web in the longitudinal direction in the central region of the cylinder.
    In the utility model publication Fl 8933 U a roller part is shown for a Segment¬walze, in which at both axial end surfaces of the end parts on a support axis for the roller part connecting elements are arranged; by means of the connecting elements, two successive rolling elements can be separably coupled to one another, and the supporting axis is composed of at least two parts whose position relative to each other is variable for varying the axial length of the supporting axis; the roller member includes a roller shell rotatably supported on the support shaft, and the roller jacket is supported near the both ends with a flange construction by the bearing on the support shaft so that the flange constructions between them together with the roller shell define a substantially closed space on the roller member and at at each flange construction / end fitting combination of the roll member, a sealing member is disposed to minimize dust penetration.
    As is well known, the segment roller of the prior art is composed of roller members in such a way that a first connecting part located at the end of the roller part, an intermediate piece, is supported on a second connecting part of the following roller part, an intermediate support. In practice, the connection has little play for assembly and production reasons, which causes a micromotion during the operation of the segment roller due to vibration of the support beam on the segment roller or imbalance of the segment roller at the connection Time can expand the game in the Ver¬ binding, whereby between the roll parts of the segment roller a height difference arises, for example, a gradation, which can be visible as a strip in the fiber web to be produced and also cause a vibration increase.
    The purpose of the invention is to obtain a novel roller part for forming a segment roller, wherein not only the individual roller parts are separable and replaceable without disassembling the entire roller and the roller can be smoothly bent, but also the micro movement in the connection between the roller parts eliminated or minimized.
    To achieve the purposes set forth above and later mentioned, it is mainly characteristic of a roller part for a segment roller according to the invention, which is shown in the characterizing part of claim 1.
    Further advantageous embodiments for a roller part according to the invention are shown in the claims 2 to 5.
    According to the invention, the roller part comprises, as micro-movement-free connection, two clamping and fastening devices for clamping the connection between connecting parts of adjacent roller parts.
    According to an advantageous embodiment of the invention, the connecting parts for the support shaft on the roller part of an intermediate piece and an intermediate support.
    According to an advantageous embodiment of the invention, the respective clamping and fastening devices comprise a clamping screw and a fastening part, which are to be positioned between the intermediate piece and the intermediate support of the juxtaposed Walzent¬eile with the ends.
    According to an advantageous embodiment of the invention, the two clamping and fastening devices are arranged on one end side of the roller part in the upper half of Walzzenteils on both sides of a locking element.
    According to an advantageous embodiment of the invention, the two juxtaposed roller parts are connected to each other without micro-movements by means of a Dreipunkt¬befestigung.
    According to an advantageous embodiment of the invention, the two clamping and fastening devices are arranged on one end side of the roller part in the upper half of Walzzenteils on both sides of a locking member in such a way that the existing between the two clamping and fastening devices angle is 120 °.
    According to an advantageous embodiment of the invention, the two juxtaposed with each other roller parts are connected to each other without micro-movements by means of a Dreipunkt¬befestigung, being achieved by the clamping and fastening devices two verstellba¬re fixed points and also a fixed fixed point and the total three fixed points of the three-point attachment in a pitch of 120 "are positioned.
    In the following, the invention will be explained in more detail with reference to the figures of the attached drawing; it is not the intention to limit the invention in any way by the figure details.

    In the following figures, corresponding parts and subpopulations are represented by the same reference numerals.
    The segment axis schematically illustrated in Fig. 1 comprises three successively positi¬onierte roller parts 10, of which the two first with one end by means of a support member 23 on a mounting pad 5 or a corresponding support body and with the other end on an end face of an adjacent roll part 10 support. The last two ends of the roller part 10 in the roller train are supported on the mounting pad 5 by means of supporting parts 23. Each individual roller member 10 is rotatably supported on its own support shaft. In Fig. 1 suggestively belonging to the support member 23 Befestigungs¬ and adjusting elements 21, 22 are shown, advantageously adjusting screws with which the straightness of the roller parts 10 for the segment roller is adjustable with respect to the pad.
    In Fig. 2, a projection of the end of a segment roller is shown schematically, ausder the attachment and adjustment elements 21 emerge for the support member.
    Hereinafter, the construction of a roller member 10 and a connection between the two roller parts 10 will be explained with reference to Figs. The construction of the roller part 10 at one end of a segment roller differs from the other roller parts primarily only in that its two ends are equipped with a support member 23 for supporting on a support pad 5, as shown in FIGS. 1 to 2 evident. Each roller member 10 includes a roller shell 12 and associated flange structures 13. The flange structures are located in the direction C of the longitudinal axis of the roll mantle 12 near both ends of the roll mantle; This direction is also referred to herein as the axial direction. The roller member 10 comprises a support shaft 11, and via the bearing 20 arranged in this connection, the roller shell 12 is supported in the support shafts 11. The support shaft 11 for the roller member 10 is formed of two flange-type connecting members 16, 18, hereinafter referred to as the intermediate support 16 and intermediate member 18. The intermediate support 16 and the intermediate piece 18 are positioned in the roller part 10 in such a manner that the outwardly facing surfaces of the roller part 10 on the intermediate support 16 and on the intermediate piece 18 as end surfaces of the roller part 10 and thus also as connecting surfaces in the connection between two successive rolling parts 10 serve. The intermediate support 16 and the support axle spacer 18 are connected to each other by a central axle piece belonging to the intermediate support 16, for which the term axle journal 17 is used below, which extends continuously through the roller part 10 into the borehole in the intermediate piece 18. In a normal situation, i.e. when the segment roller is ready for operation, the intermediate piece 16 and the support shaft intermediate support 18 are locked against rotation when mounted in a locked position in the journal 17 by means of a fixing screw 36. The attachment and detachment of the fastening screw 36 takes place through an opening 39 provided in the jacket.
    The intermediate support 16 is fastened by means of the support member 23 to the segmental support bearing pad. The support member 23 may be a separate part or form a common part with the intermediate support 16. From the center of a disk-like piece on the intermediate support 16 projects a journal 17 directed into the roller part 10, which extends in an axial direction through the flange construction 13 and the intermediate piece 18 to the vicinity of the other end of the roller part 10. At the extreme end of the journal 17 there is an externally threaded part, on the peripheral surface of which a planner area for the locking to be effected with the fixing screw 36 is arranged.
    The intermediate piece 18 for the roller part 10 adjacent to the roller part 10 serves as a counterpart for the intermediate support 16. The intermediate support 16 for the roller part 10 and the other end of the roller part 10 positioned intermediate part 18 together form the Stützach¬se 11 for the Roller part 10. The intermediate piece 18 is a disk-like piece, from the middle of which a sleeve 33 directed into the roller part 10 protrudes. The axial borehole 19 for the sleeve 33 extends continuously through the entire intermediate piece 18. The flange construction 13 and the axle pin 17 in the intermediate support 16 and the sleeve 33 on the intermediate piece 18 are not in direct contact with each other.
    On the outer circumference of the intermediate piece 18 is a borehole 35 with internal threads, which extends up to the continuous through the intermediate piece 18 axial borehole. In the borehole serving as a locking element fixing screw 36 is positioned, which has two main working positions. In the first position of the fastening screw 36, its tip, which is directed against the center axis of the roller, is pressed against the planar area located on the peripheral surface of the outer part of the journal 17. As a result, the fastening screw 36 holds the intermediate piece 18 in firm contact with the immovable intermediate support 16 and thus prevents the intermediate piece 18 from twisting. At least the part of the drill hole axially continuous through the intermediate piece 18, which passes through an end flange on the intermediate piece 18, is with an internal thread provided corresponding to the external thread of the outer part of the journal 17 for the intermediate support 16.
    The roller member 10 is mounted with two bearings 20, preferably deep groove ball bearings, in the support shaft 11, which are formed by the intermediate support 16 and the intermediate piece 18. The bearings are positioned in conjunction with the flange structures 13 for the roller member 10 in such a manner that the inner circumference of the bearings 20 rotate with the flange structures 13. The stationary outer periphery of the bearings 20 rests on the inner surfaces of annular recesses in the intermediate support 16 and in the intermediate piece 18. Since the inner surface of the flange constructions 13 for the roller part 10 is not in direct contact with the parts for the support shaft 11, the bearings form The main object of the axle pin 17 for the intermediate support 16 and the sleeve 33 for the intermediate piece 18 is as a connecting element in interconnecting the intermediate support 16 for the support shaft and the intermediate piece 18 to serve.
    According to the invention, the roller part 10 is provided with two clamping and fastening devices 51, 52 shown in Fig. 4, whereby the connection between the Zwi¬schenstück 18 and the intermediate support 16 can be tensioned to the micro movement of Verbin¬ dung between To prevent the roller parts 10. Each tensioning and fastening device is formed by the clamping screw 51 and the fastening part 52; the tensioning and fastening device can be positioned between the intermediate piece 18 and the intermediate support 16. The longitudinal fastening part 52 is fastened with the clamping screw 51. By means of the tensioning and fastening devices 51, 52, a suspension point 53 is attached.
    It is brought about that the intermediate support 16 of the juxtaposed roller parts 10 and the intermediate piece 18 immovably supports and couples with each other. The tightening screw 51 is tightened by means of a key to be pushed through the opening 39 in the shell 12, and the opening 39 is positioned in place of the two-sided tightening screws 51 by turning the shell 12 once. When tightening the clamping screw 51, the Befesti¬gungsteil 52 is in the upward movement against a stop surface 57 on the Zwischen¬stütze 16. The fastening part 52 is preferably a rotationally symmetrical axial part, on which einsich on the abutment surface 57 supporting section 55 is attached , As emerges from FIG. 5, the tensioning and fastening devices 51, 52 are arranged such that they provide a fastening connection and their suspension points 53 on the circumference between the intermediate support 16 for the roller parts 10 and the intermediate piece 18, or in FIG more suitably, on the upper half of the roller part 10, on both sides of the fixing connection formed by the fixing screw 36. In this way, a fixed Dreipunktbe¬ festigungsverbindung for connecting two juxtaposed with the ends Walzentei¬len be brought together. The fastening connection has a three-point suspension in which two adjustable suspension points 53 have been created with the tensioning and fastening devices 51, 52 and the third is a fixed suspension point 54 between the intermediate support 16 and the intermediate piece 18. As is apparent from Fig. 5, according to the invention, the suspension points 53, 54 are preferably positioned at a pitch of 120 °.
    For assembling the segment roller, first the first roller part 10 in the roller train having support parts 23 at both ends of the roller part is attached to the mounting base and thereafter as its extension the next roller part 10; this roller part 10 is lifted into the roller train in such a way that a bracket 41 in the end face of the intermediate piece 18 seats in the recess 29 in the end face on the adjacent roller part, whereby the roller part 10 is taken over by the control of the adjacent roller part. Thereafter, the support member 23 for the roller part 10 is attached to the Befestigungsun¬terlage. The measures described above are also carried out for the next roll part and so on until a segment roll is formed from the roll parts.
    As is apparent from the examples shown, the connecting elements for coupling the two successive rolling elements 10 are formed together on the end surfaces of the support shaft 11 for the roller part. In the roller part 10 according to the invention, a console is formed on the outer surface of the intermediate piece 18 and on the outer surface of the Zwischen¬stütze 16 with said console a substantial uniform depression. From the examples shown in the figures, it can be seen that the connection between two roller members 10 is formed between the first roller member spacer 18 and the end surfaces on the intermediate support 16 for the second roller member. When two roller parts 10 are positioned in contact with each other in succession, the bracket 41 provided on the end surface of the first roller part spacer 18 is located in the recess 29 on the end surface of the intermediate support 16 for the second roller part, in which it is properly selected Space can rotate and tilt within certain limits.
    The roller parts 10 of the segment roller are brought into a desired line with the fastening and adjusting parts 21, 22, according to which the shell 12 of the roller part 10 is rotated according to the invention in such a way that the opening 39 at the location of the first clamping and Fasteners 51, 52 is located. The tensioning screws 51 positioned in the intermediate piece 18 are tightened, whereupon the fastening part 52, when lifted up, attaches to the abutment surface 57 on the intermediate support 16, immovably supporting the intermediate piece 18 and the intermediate support 16. Next, responsive actions are performed at the location of the other tensioning and fastening devices 51, 52. With the clamping and fixing parts 51, 52, the connection between each intermediate piece 18 and each intermediate support 16 is tightened to prevent micro-movement.
    When the roller part 10 is to be disassembled from the center of the segment roller according to the invention, the tensioning and fastening devices 51, 52 are first opened by loosening the tensioning screws 51 and then the support shaft 11 fixing screw 36, which releases the Intermediate piece 18 secured against rotation in the relevant intermediate support 16. In order for the fastening screw 36 to be released from the outside of the roll, a continuous opening 39 is arranged on the roll shell 12 at a position corresponding to the position of the fastening screw 36, which is surrounded by the recess located on the inner surface of the roll shell 12. To loosen the fastening screw 36, a key is pushed through the opening 39, with which the fastening screw 36 is unscrewed until the fastening screw head rests in the recess on the inner surface of the roll shell 12. As a result, the tip of the fastening screw 36 is not in contact with the axle journal 17 for the intermediate support 16, and the intermediate piece 18 is under the control of the roller shell 12 by means of the fastening screw 36. In this phase, the shell 12 of the roller part 10 is rotated in a suitable direction by a certain amount, wherein the intermediate piece 18 rotates with the roll shell 12. Through the outer thread present in the end area of the journal 17 and the internal thread present in the bores of the intermediate piece 18, the intermediate piece 18 on the journal 17 slides against the flange construction 13.
    As a result of the movement, the bracket 41 at the end face of the intermediate piece 18 disengages from the recess 29 at the end face of the adjacent roll mantle, and the roll part 10 moves back out of control of the adjacent roll part.
    The above-described measures are also carried out for the roller part located on the other side of the roller part 10 to be disassembled, after which the support part 23 for the roller part is separated from the mounting base and the roller part 10 is lifted away. The positioning of the roller part in the roller sequence is carried out in reverse order.
    The segment roller construction can also be executed in many other ways. The connecting elements for the end surfaces on the roller parts are preferably concentric parts, whereby the separation of the roller parts from each other by rotation can be assumed.
    The invention has been described above only with reference to some of its preferred examples, the details of which the invention is not limited in any way, but many variations and modifications are possible.
