    Description: [0001] The invention relates to a shaft-hub connection. Furthermore, the invention relates to a method for manufacturing or assembly and a method for dissolution or disassembly of such a shaft-hub connection.
    Shaft-hub connections can be executed positively for torque transmission. Thus, it is customary to mount a hub with its internal toothing on an outer toothing having portion of the shaft, preferably with play. The mounting of the positive connection between the shaft and hub with clearance is advantageous to allow easy assembly and subsequent disassembly. However, the assembly with game can be for reasons of unwanted noise during operation, unwanted imbalance and increased wear of disadvantage. The play-free mounting of the hub on the shaft by, for example, a press fit with excess shaft makes it difficult to assemble and disassemble the shaft-hub connection.
    There is therefore a need for a shaft-hub connection with which the disadvantages of known from practice shaft-hub connections can be eliminated, which is therefore easy to assemble and disassemble at low noise, low imbalance and less wear.
    Proceeding from this, the present invention seeks to provide a novel shaft-hub connection and method for manufacturing or assembly and dissolution or disassembly thereof.
    This object is achieved by a shaft-hub connection according to claim 1. According to the invention, in the section having the external toothing, the shaft has, radially inward from the external toothing, a recess into which a clamping body is inserted while canceling the clearance between shaft and hub.
    In the inventive shaft-hub connection, the inherently play-related positive connection of hub and shaft on the interlocking teeth by the clamping body, which serves the expansion of the external toothing having portion of the shaft, designed without play. By ensuring easy assembly and disassembly unwanted noise, unwanted imbalance and unwanted wear can be counteracted.
    According to an advantageous embodiment, the recess is conically or funnel-like contoured and tapers from the axial end of the shaft inwardly into the shaft, wherein the clamping body is correspondingly cone-shaped or frustoconical contoured and particularly advantageous at least partially having an outside diameter, which is larger than an adjacent inner diameter of the recess. Hereby, a particularly advantageous mounting of the hub on the shaft while canceling the game of the backlash-related teeth between shaft and hub is possible.
    Preferably, the clamping body has a hydraulic connection and hydraulic lines, over or during the assembly and / or disassembly of the clamping body in the recess of the shaft, the recess is radially expandable. About the hydraulic connection and the hydraulic lines, a particularly advantageous assembly and / or disassembly of the shaft-hub connection is possible.
    Preferably, a disc secures the clamping body inserted into the recess. As a result, the shaft-hub connection can be secured against accidental release.
    The method for producing or mounting the shaft-hub connection is defined in claim 6.
    The method for dissolution or disassembly of the shaft-hub connection is defined in claim 9.
    Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawings. Showing:

    The shaft 2 has in the outer toothing 5 bearing portion 4 radially inwardly of the external teeth 5 a recess 7. In this recess 7, a clamping body 8 is inserted and while canceling the game between the play inherent positive connection between the shaft 2 and hub 3, which is provided on the intermeshing teeth 5, 6 of shaft 2 and hub 3.
    For this purpose, the clamping body 8 has at least in sections on an outer diameter which is greater than the inner diameter of the recess 7, so that the inserted into the recess 7 of the shaft 2 clamping body 8 the
    Section 4 of the shaft 2, which carries the external teeth 5, with the suspension of the game between the teeth 5, 6 preferably expands to produce a bias between the shaft 2 and hub 3.
    Optionally, in the region of the teeth 5, 6 formed on the shaft 2 and hub 3 centering surfaces can be made by the clamping body 8 also free of play.
    In the illustrated, preferred embodiment, the recess 7 in the section 4 of the shaft 2 cone-like or funnel-like contoured in such a way that the recess 7, starting from the axial end of the shaft 2 tapers inwardly in the shaft 2 in the axial direction. The clamping body 8 is correspondingly cone-shaped or frustoconical contoured, namely, as already stated, such that an outer diameter of the same at least in sections thereof is greater than a corresponding, adjacent in the mounted state or opposite inner diameter of the recess. 7

    At the hydraulic port 10 while a hydraulic system, not shown, can be connected, wherein hydraulic oil via the hydraulic lines 11,12 in the direction of a contact region 13 between the outer diameter of the clamping body 8 and the inner diameter of the recess 7 of the shaft 2 can be performed. The hydraulic line 11 extends in the axial direction and the hydraulic line 12 in the radial direction.
    For producing or mounting such a shaft-hub connection 1, a shaft 2 is provided with an external toothing 5 and the recess 7 having portion 4 and a hub 3 with an internal toothing 6. Furthermore, a clamping body 8 is provided, which at least in sections has an outer diameter which is at least partially larger than an in the assembled state adjacent or opposite inner diameter of the recess 7 of the portion 4 of the shaft 2. The hub 3 is positively mounted on the shaft 2, preferably with play between the internal teeth 6 of the hub 3 and the external teeth 5 of the shaft 2 at the section 4 thereof. After this form-fitting, preferably clearance-bearing mounting of the hub 3 on the portion 4 of the shaft 2, the clamping body 8 in the recess 7 of the shaft 2, canceling the clearance between the shaft 2 and the hub 3, preferably generating a bias between shaft 2 and hub 3 mounted.
    For this purpose, either the clamping body 8 is cooled relative to the section 4 of the shaft 2 and / or the outer toothing 5 having portion 4 of the shaft 2 is heated or heated relative to the clamping body 8. As a result, the relative excess of the clamping body 8 relative to the recess 7 of the shaft 2 can be thermally released to simply insert the clamping body 8 in the recess 7 of the shaft 2. After temperature compensation then there is a press fit between the clamping body 8 and section 4 of the shaft 2, which widens the section 4 of the shaft 2 radially and thus the game between the teeth of the hub 3 and shaft 2 cancels.
    Alternatively or additionally, for mounting the clamping body 8 in the recess 7 of the period 2 of the external toothing 5 and the recess 7 having portion 4 of the shaft 2 are hydraulically expanded, namely using the hydraulic connection 10 and the hydraulic lines 11,12 of the Clamping body 8.
    The inserted into the recess 7 of the shaft 2 clamping body 8 can be secured below the disc 9 in its inserted into the recess 7 position within the shaft 2 below. For this purpose, the disk 9 is preferably mounted on the shaft 2 via a screw connection.
    To disassemble or release the shaft-hub connection 1, the optional disc 9 is first removed and then the clamping body 8 is removed from the recess 7 of the shaft 2 and while restoring the play between the shaft 2 and the hub 3, wherein subsequently the hub 3 is removed from the shaft 2. To disassemble the clamping body 8 from the recess 7 of the shaft 2 of the external teeth 5 and the recess 7 having portion 4 of the shaft 2 is radially expanded, preferably hydraulically using the hydraulic connection 10 and the hydraulic lines 11,12 of the clamp body eighth
    It is therefore within the meaning of the present invention to provide a shaft-hub connection 1 between a shaft 2 and a hub 3, which initially the hub 3 on the shaft 2 form-fitting with clearance via intermeshing teeth 5, 6 mounted , wherein subsequently over the clamping body 8 inserted into the recess 7 of the shaft 2, the play between the toothings 5, 6 is preferably canceled, producing a prestress between the shaft 2 and the hub 3. For this purpose, the clamping body 8 is preferably frustoconical or conically contoured, wherein the clamping body 8 receiving recess 7 of the shaft 2 is contoured conically or funnel-like contoured.
