    the boom shaft and the attachment tool, the additional and rotary shafts of the tiltrotator can be used, whereby the tiltrotator can be pivotally mounted on the previously mentioned boom shaft, for example via the previously mentioned swivel piece, which by means of a pressure medium cylinder can be pivoted about a pivot axis extending transversely to the longitudinal axis of the boom shaft so that, when the tiltrotator provides access to two tilt- resp. axes of rotation, a total of three-axis pivot resp. tiltability can be achieved with the attachment.
    The tiltrotator can in this case advantageously provide a tilt axis which. usually. is set up. transverse to the pivot axis which is realized directly on the excavator shaft and thereby. extends more or less parallel to resp. only slightly angled inclined towards the two. plan, som. are defined by the two forming transverse coupling parts resp. their connection plan.
    Substantially vertical to the said tilt axis resp. for the tiltrotator and towards the pivot axis realized directly on the boom shaft, a rotation shaft extends in turn which extends substantially vertically towards the above-mentioned coupling planes for the two Vid for the boom shaft and the rotator coupling parts mounted on the boom shaft. conventional configurations / the tilting device with the attachment on it in turn in a conventional working position towards the ground, the orientation of the above-mentioned tilt axis can extend horizontally towards the vertical longitudinal central plane of the boom shaft, while the axis of rotation of the tiltrotator extends in the upright direction. But this of course depends on the currently set turning and tilting angles. between the tiltrotators the attachment tool and the boom shaft are mounted. If such increases the distance between the attachment tool and the excavator shaft, whereby the required adjusting forces become larger as 10 15 20 25 30 35 provide manpower and torques the levers to require larger, for example to push down a digging shaft in the earth Conversely, it increases with. by means of a pulling and turning movement. the reaction forces clearly on when the relevant storage locations, the It is thus the tool is forced into the ground with driving force that the boom shaft can provide. it is advantageous to keep the construction height of the tiltrotator down as much as possible in order to keep down the distance between the attachment and. the cantilevered end of the boom shaft and thus hold the lever. down the dimensions of the thus coordinated with respect to such tiltrotators, it is the width longitudinally Second, however, not only the construction height but also transverse to the vertical center plane of the boom shaft is relevant, since a tiltrotator which involves an injury narrow. is protruding beyond the width of the excavator collision potential and tends to tiltrotator, Apart from this, an overly wide tiltrotator can about. the excavator in question is very much also limiting the reachable work space, for example when joining. a very narrow excavator should pull up or width so that the tiltrotator does not dig a deep, narrow trench, the essence of which corresponds to the width of the excavator, can be driven in when the excavator has to go deeper.
    Nevertheless, despite the mentioned cases and torque, the tiltrotator must provide the requirements for a low construction height in each respective to provide sufficient tilts in order to be able to achieve a high working power. The object of the present invention is to provide an improved rotator / tilt assembly of the type mentioned in the introduction, and in which the disadvantages according to the current prior art are avoided and the technology is developed in an advantageous manner. In particular, a compactly built tiltrotator is provided with an extremely low construction height and which at the same time is narrow, and which, despite its neat construction, can deliver high tilting and rotational forces.
    According to the invention, the object is achieved by a rotator / tilt assembly according to claim 1. Preferred embodiments of the invention are included in the appended claims.
    According to the invention, it is proposed that the tilt and rotation axes of the drive devices which belong together next to crosses with the rotator / tilt assembly should be arranged so that their drive axes are no longer each other. with its longitudinal axes, so that the drive axles can be moved closer to each other. The drive shafts are hereby advantageously arranged in a common housing block so that the dimensions can be kept down. According to the invention, the tilt assembly and the worm screw are coordinated. with. the axis of rotation. arranged essentially an undivided, parallel to. each other and are housed in a common rotor body. In this way, not only the construction height of the rotator / tilt unit, ie. the extent of the rotator / tilt unit perpendicular to the coupling plane for both because the coupling parts resp. the distance between them is made very small, to the worm screw, the coupling parts, must take into account any collision between the tilting unit and as is the case when the shafts pass over each other. Secondly, the width can also extend transversely to the tilt axis of the rotator / tilt assembly, ie. its and parallel to the coupling plane defined by the coupling parts, are kept down, since the dimensions for this extent are no longer defined by the length of the worm screw. In addition, the two drive shafts for the tilt and rotator assemblies can pass through. integration into a common rotor body, are moved particularly close together as designs with double walls, intermediate connecting flanges and the like, as well as sufficiently strong fasteners such as bolts and the like can be avoided. In further development of the invention, the piston coordinated with the tilt shaft may. resp. the tilting unit, the displacement of which is longitudinal. converted into a tiltrorelse, show flattened. cross-section deviating from the circular shape, with two mutually at least substantially perpendicular major axes of different lengths, the piston being advantageously arranged in such a way that both substantially the shorter of the major axes in the transverse section of the piston extend or only slightly parallel to acute angular inclination towards the rotator- The piston can thus in the rotary axis of the attachment. the rotator / actuator ie. both coupling parts, resp. flattened to be able to provide. sufficient direction for construction height, the distance between them being compressed transversely to the construction height, high adjusting forces at further reduced construction height.
    The transformation. of the linear adjusting movement of the drive piston to the desired rotational driving movement of the tilt drive shaft can in this case take place in different ways. For example, the drive shaft on the outside may be provided with screw teeth which engage in a screw tooth rotating on the inside in a passage recess of the piston. Alternatively or in addition, the piston can also be provided with a screw tooth extending on the outside with which the piston is in screw engagement with. the rotor housing.
    However, according to an advantageous further development of the invention, the piston may also comprise a reduced section. diameter, sonl is provided with. screw tooth that engages an inner recess for the tilt drive shaft, which may be shaped. as. hollow shaft to engage in screw engagement with said piston section. The piston can in turn be designed with a smooth outer circumference and by deviating from longitudinal direction, its cross-sectional configuration can be inserted in a rotationally stable SOITI circular shape and slidably in the rotor housing. As a result, high rotational adjusting forces are achieved at the same time as. a very compact construction. According to a further development of the invention, the worm gear of the rotator assembly and the tilt drive shaft of the tilt assembly can be arranged resp. be accommodated in separate mounting spaces in the common rotor body, whereby also advantageously the piston belonging to the tilt drive shaft and the worm wheel which is coordinated with the worm screw are placed in separate mounting spaces in. undivided rotor body. According to an advantageous development of the invention, the rotor body has a first mounting space for mounting the tilt drive shaft and / or the cooperating piston, a second mounting space for mounting the worm screw and a third mounting space for mounting the worm wheel, the first mounting space being designed separately from it and / or the undivided second mounting space from the third mounting space through wall sections of the rotor body. Alternatively or in addition, the second and the connection to each other, in the mounting space the third mounting space can be in particular via a passage opening, which connects the second mounting space to the third mounting space in such a way that the worm wheel with an engaging portion can reach the worm screw mounting space to stand in engagement with the worm screw arranged therein.
    In principle, the rotor housing can be designed in another way, a central in particular in several parts, for example in the form of a rotor body which houses the tilt and rotation assemblies and with these and additional parts connectable closures such as covers or bearing parts. According to a development of the invention, the previously mentioned joint which the screw screw and the tilt drive shaft, preferably also the worm wheel and. the Inst and the flask. son1 is coordinated with the tilt drive shaft, a monoblock-like, integral part or a structural part, for example in the form of a cast part composite material part, and / or in the form of a laminated aramitic carbon fiber component, or optionally in a piece designed welded construction part. If a housing body of the monoblock type in the form of a casting part is arranged, wall contours and wall thicknesses can be dimensioned adapted to the voltage profile, a low gap, enabling in particular which thereby rotor housing can be tightly assembled Alternative to compact, an arrangement for the rotor body assembly components. can, however, also anticipate to be assembled, for example screwed together, by several parts, whereby for example a part for mounting the worm screw part the tilt drive device including the piston. According to an advantageous development of the invention, the previously mentioned third mounting space in which the worm wheel of the rotary unit is accommodated, may have a longitudinal axis transverse to the longitudinal axis of the first mounting space and / or to the longitudinal axis of the second mounting space, the longitudinal axis of said third mounting space can advantageously extend in particular substantially perpendicular to the longitudinal axis of the first which for the mounting space in the tilt drive shaft. is housed. Alternatively or in addition, the longitudinal axis of the third installation space may be arranged substantially perpendicular to the coupling plane for distance from each other the two on the horizontal coupling parts of the rotator / tilt assembly.
    In order to enable easy mounting and a module-like construction for the drive device, the diameter of the rotor housing, which is considerably larger in terms of diameter, can be open to a surface and in particular have an end side which is open relative to the longitudinal axis, so that the worm wheel 10 In the rotator assembly and advantageously also the rotary bearing device for the rotatable bearing for * the associated coupling part, can be inserted and mounted from the open side of the mounting space.
    Alternatively or in addition, the said third mounting space can be closed with a cover part, the use of one which can be designed as a bearing cover through which a part of the rotating drive part passes during rotational movement, the rotation, so that the worm wheel is carried out to the outside *. coupling part. by means of the rotating drive part passing through the cover part.
    Alternatively or in addition, the first mounting space and / or the second mounting space for the tilt drive shaft resp. the worm screw at its respective end sides must be provided with at least one opening to enable insertion of the tilt unit resp. the worm screw from its respective end faces. The corresponding openings for the first mounting space and / or the second mounting space present on the end sides can advantageously be closed by means of suitable cover parts.
    Depending on the gear ratio required between the rotor speed of the worm screw and the desired rotor speed of the axis of rotation of the rotator / tilt unit, one or more gear stages, for example in the form of gears, may be arranged between the worm screw and the rotary drive device.
    For example, the worm wheel in engagement with the worm screw may drive a gear which is connected to the rotating shaft of a drive shaft. In order to achieve a particularly compact construction with few components, according to a development of the invention, the worm wheel can also form the single gear stage between the worm screw of the rotator assembly and the rotating drive shaft. In particular, 10 l5 20 25 30 35 as. stands in coaxial worm gear engages with. worm screw. be arranged with the axis of rotation of the rotator / tilt assembly and be rotationally connected to either of them, possibly via intermediate coupling elements. According to a development of the invention, said worm wheels can advantageously be arranged immediately below resp. adjacent to the piston of the tilting unit and be separated from it only via the thickness of that wall, and / or wall along longitudinal direction. be separated as. the cylinder wall of the piston forms the one in which the piston can be displaced in the worm wheel can in particular advantageously from the piston resp. from the installation space in which the tilt drive shaft and the associated piston are arranged, via an integral wall portion in said common rotor body, a minimum distance is obtained in the direction of the monoblock type. Hereby a minimum height distance, ie. the axis of rotation between the tilt assembly and the rotator assembly, in particular between the tilt drive shaft and said tilt drive shaft and said worm screw measured the worm screw. are in this case advantageously, however, in the direction of the rotation axis of the rotator / tilt unit, arranged at a distance from each other resp. displaced with respect to their axes of rotation, in order to facilitate the insertion of the worm wheel, but also in order not to be in the way of an oval or elliptical extension of the piston. This allows a very low construction height. combined with. a very slim, ie. low width of the rotator / actuator.
    According to a development of the invention, the worm screw can advantageously be arranged in such a way that the transverse distance between the rotating shaft of the worm screw and the rotation shaft of the worm wheel, measured perpendicular to the axis of rotation, is greater than the height distance between the worm shaft rotating shaft and the tilt axis. the worm screw has been moved closer to the tilt axis in terms of height than the worm screw has been moved widthwise towards the rotating shaft in terms of width. Herein can a special. low construction height. achieved for the rotator / tilt unit. Advantageously, the height distance between the rotary shaft of the worm screw and the tilt axis can amount to about 50% -90%, in particular about 60-70% of the said transverse distance between the rotary shaft of the worm screw and the rotational shaft of the rotator / tilt assembly. In this way a good compromise is achieved between, on the one hand, low construction height and, on the other hand, low width expansion, which on the one hand enables favorable lever conditions and favorable. application of force and. on the other hand, freedom of movement in the case of narrow attachments. as. The worm wheel is coordinated with the worm screw of the rotator assembly is advantageously arranged in a plane which is configured substantially parallel to the coupling plane both substantially for those coupling parts and / or is arranged perpendicular to said axis of rotation and parallel to the tilt axis. The worm wheel can in this case be arranged directly below the mounting space for the tilt drive shaft and the piston coordinated therewith, preferably substantially only separated by the corresponding partition wall of the rotor housing. In particular, the free width between the worm wheel and / or worm screw on the one hand and the piston in the tilting unit on the other hand, measured in the direction of the rotator / tilting unit's preferably less than 25% axis of rotation may be less than 50%, than 33%, in particular also less than the maximum piston diameter.
    In order to be able to combine on the one hand a low construction height with sufficiently good levers and low reaction forces and on the other hand good insertability in shafts, even with narrow attachments, is according to a development of tilt drive shaft and the fact that the drive device with the invention the arrangement therewith. samornadekolven. and the worm screw in so arranged to each other so as to be arranged between the coupling parts of the rotator / tilt assembly has one. height, measured. in the direction of the axis of rotation, son1 is less than 66%, preferably less than 55%, in particular about 33% -55%, of the longitudinal extent of the drive device, matt in the direction of the tilt axis.
    Since a slenderness of the rotator / tilt unit in particular in terms of the transverse extent, ie. in the direction perpendicular to the tilt axis and perpendicular to the axis of rotation, is of importance, while conversely a low construction height in the longitudinal direction, i.e. in significant, the less advantage needed tiltax direction is allowed resp. be arranged with space for the drive device as for the sufficient adjusting movements in said longitudinal direction. According to an advantageous embodiment. according to the invention, one can be arranged between the tilt shaft having a width preferably about 50% -70% drive device measured as the coupling parts, transverse to and transverse to the axis of rotation, which. is less than 75%, of the length of the drive, measured in the direction of the tilt axis.
    The present invention will now be explained in more detail with the aid of a preferred embodiment and associated figures. The figures show the following: Figure 1: is a schematic side view of a rotator / tilt assembly according to an advantageous embodiment of the invention, son1 is mounted on a boom shaft for an excavator and which carries an excavator as an attachment tool, Figure 2: is a schematic view in perspective of the rotator / tilt assembly in Figure 1. in the disengaged state where one can see the side-by-side parallel arrangement of the worm gear in the rotator assembly, 10 l5 20 25 30 35 _l2_ Figure 3: is a schematic perspective view of the rotator / tilt assembly similar to the in figure 2 from another son1 shows * the point of view, side. of the drive device opposite the worm gear, Figure 4: is a longitudinal section through the rotator / tilt assembly from the previous figures in a section which. comprises the axis of rotation and axis of rotation of the rotator / tilt assembly, and Figure 5: is a cross-section through the rotator / tilt assembly of the preceding figures in a cross-section comprising the axis of rotation perpendicular to the tilt axis.
    As can be seen from the figures, the rotator / tilt assembly 1 can be mounted between the free end of a boom shaft 2 on an excavator 3, and an attachment tool 4 which can be mounted thereon, the attachment tool 4 in Figure 1 being designed as an excavator. The rotator / action unit 1. can. one side, by means of a first coupling part 5, is mounted on said excavator arm 2 so that it can be pivoted about a horizontal pivot axis directed towards which is transverse to the pivot axis of the excavator arm 2, so that the rotator / tilt assembly as a whole can be pivoted relative to the excavator arm 2. for example using a pressure medium cylinder 6 and an intermediate pivot piece 7 On the other hand, the rotator / tilt assembly 1 is provided with a second coupling part 8, by means of which a current desired attachment tool 4 can be mounted on the rotator / tilt assembly 1. As. As can be seen from Figure 4, it and / or the coupling part 5 can be designed as quick couplings and the second coupling part 8 the first comprise adjustable quick-locking devices, for example bolts, in order to be able to be coupled to the attachment tools, which. usually provided with 10 15 20 25 30 35 _l3_ transverse bolts, or on the excavator arm and to bolts thereof. Those for the first and second coupling parts 5 and 8 define the non-tilted transverse ones which are arranged at defined joint points resp. the locking arrangements previously mentioned. the coupling plane, which - in the intermediate position of the rotator / tilt unit - are arranged at a distance from each other, in the direction almost parallel or only slightly angled towards each other. both son1, the rotator / tilt assembly 1 may comprise between the coupling parts E5 and 8 a. drive device 9, turn resp. rotate both coupling parts 5 and 8 biaxially relative to each other. On the one hand, the drive device 9 has a tilt axis 10 which extends substantially parallel to the coupling plane of the first coupling part 5 and transverse to the pivot axis of the excavator shaft 2, said tilt axis 10 being arranged just below or at a distance from the coupling or locking devices for the first coupling part 5, cf. figure 4. With the aid of said tilt shaft 10 the attachment tool 4 in relation to a vertical longitudinal central plane, by means of the excavator shaft 2, can be pivoted from right to left resp. with respect to Figure 1, out of the plane of the figure and back.
    Furthermore, the drive device 9 realizes a axis of rotation 11, which extends perpendicular to said tilt axis 10.
    Hereby the second coupling part 8 and the attachment tool 4 which. is mounted on this, in the connection plane resp. with respect to an axis standing upright in Figure 1, it is rotated perpendicularly both to the tilt axis 10 and also to the pivot axis realized on the excavator stick. and as shown in Figure 4, a longitudinally displaceable piston 10 comprises a piston 10 which cooperates with an associated tilt drive shaft 13 extending coaxially with said tilt axis. Said piston 12 is in this case slidably inserted into a cylindrical recess in a rotor body 14, which is mounted on the coupling part 5 and which is tiltable about the tilt shaft 10. The rotor body 14 for this purpose comprises a first which extends through the rotor housing parallel mounting space 15, 18 for the drive device 9 - substantially - with the direction of the tilt shaft 10.
    The piston 12 has in this case advantageously a flattened, in elliptical cross-section or the outer contour piston 12 is flattened. With the cross-sectional contour the piston 12 is longitudinally displaceable but the flattened particularly oval resp. for the said designed with resp. Oval shape. the oval not rotatably inserted in cylindrical and complementary to the piston resp. oval shaped recess in the mounting space 15.
    As can be seen from Figure 4, the piston 12 may in this case comprise a section 19 of lower diameter, which on its outside may be provided with a screw tooth 20, with which a circumference such as inner recesses can engage in a tilt drive shaft 13, so that the piston 12 rotationally moves of the tilt drive shaft 13 about the tilt shaft the piston 12 in hollow shaft part longitudinal displacement of formed provides 10. Said tilt drive shaft 13 projects with its end side out of said rotor housing part 14 and is connected via a torsionally strong coupling part 5 to the first anchored fitting.
    By introducing pressure fluid, in particular the hydraulic oil piston 12, mounting space 15 can be driven axially into the said, whereby a two-sided, opposite driving movement back and forth can be produced in a manner known per se by means of the pressure chambers opposite sides of the piston. The rotating assembly coordinated with the rotary shaft 11 is also inserted in said rotor housing part 14, which for this comprises a second mounting space 16 and a third mounting space 17, which are separated from the previously mentioned first mounting space 15 for and in the rotary shaft. 11 the direction of the tilting unit is arranged at a certain distance from it.
    The third mounting space 17 forms a central receiving space concentrically below the aforementioned first receiving space 15, the diameter of said third mounting space 17 being considerably larger being twice as central as the diameter of the first mounting space 15, at least as large as the diameter. A longitudinal axis of the coaxial third mounting space 17 is arranged with the axis of rotation. 11. Mentioned. third mounting space 17 is used for mounting a worm wheel 21, which grips mounted in said second and. said worm screw 22 - mounting space 116. Said worm screw 22 - corresponding to the second mounting space 16 - extends here substantially parallel to the tilt shaft 10, the worm screw 22 with its axis of rotation being arranged at a transverse distance. from the axis of rotation 11 and partly in the height direction, ie. parallel to the axis of rotation 11, is arranged at a distance from the tilt axis 10. The transverse distance QA between the axis of rotation of the worm screw 22 and the axis of rotation 11 is in this case slightly larger than the height distance HA. between the axis of rotation of the worm screw 22 and the tilt shaft 10, cf. figure 5. According to an advantageous further development of the invention, the arrangement can be designed in such a way that said height distance HA is about 65% of said transverse distance QA.
    The worm wheel 21 is in this case advantageously completely immersed in said third mounting space 17 and arranged against the bottom of the mounting space 17, i.e. directly to the wall of the rotor housing 23 which separates the third worm gear 21 mounting space 17 from the first mounting space 15. Since the worm screw 22 can engage each other, the third mounting space 21 is connected to the second mounting space 16 via a slit-like opening, cf. figure 5.
    Housed in. The third installation space 17 is also a center layer resp. center bearing device which, for example, comprises a center bearing shaft stub or the like, for rotatably connecting resp. bearing the second coupling part 8 about the axis of rotation 11 at the rotor body 14. The rotor body 14 may advantageously comprise an annular flange projecting from the bottom in the third mounting space 17. resp. bridge 23, in order to be able to completely and completely pour the center bearing device inside the flange 23 and to arrange the worm wheel 21 outside the annular flange 23.
    The third mounting space 17 which is open to the second coupling part 8 can advantageously be closed by using a lid part 24 which covers the worm wheel 21 and which can sit on the previously mentioned flange 23 the edge side, i.e. on the edge 16 for annular 'cage for and / or on which surrounds the mounting space is formed which can be mounted correspondingly torsionally rigid. rotor body 14. worm wheel 21, Hereby a stable, worm wheel 21 by means of screw bolts 25, suitable connecting devices, for example can be connected torsionally with the second coupling part 8, the connecting devices between the worm wheel 21 and the second coupling part 8 and the center bearing device for the second coupling part 8, cover part 24. be centrally positioned, can pass through the second and third nontation space 16 and 17 advantageously form an outwardly sealed rotary gear space, with the closure, filled so that the rotator assembly can be operated substantially as can be, for example, with oil, without maintenance.
    The worm screw 22 can in principle be driven differently electrically, for example with the use of an actuator according to methods, for example by means of an electric motor, said worm screw or hydraulically, which is connected which acts on a spindle nut. Other drive options for the worm gear can also be foreseen.
    The rotor body 14, 15, 16 and 17 of the rotator assembly, which with its various mounting spaces accommodates both the tilt assembly and also advantageously designed with as a structure of shape of an undivided casting part. monoblock type, for example in Hereby not only a thin-walled, with to the power flow contour course and wall thicknesses can be achieved, compact construction adapted but also a special tilt-stable arrangement for the drive devices that run without fluctuation errors.
