Definitions
- the present invention relates to a coupling arrangement having the features of the preamble of claim 1.
- DE 202017 102 534 U1 discloses a telescopic column with at least two telescopic elements that can be moved linearly relative to one another. Furthermore, there is a drive unit connected to a first of the telescopic elements, it being possible for the force generated by the drive unit to be transmitted to the second of the telescopic elements via a connecting element.
- DE 19908 934 A1 discloses a device for adjusting the angle of rotation of a camshaft.
- a rotary vane adjuster with a stator is known, which is driven by the crankshaft, preferably via a traction mechanism and a drive wheel.
- DE 3838 118 A1 discloses a fastening element for anchoring to a flat workpiece. There is an opening in the polygonal outer surface of the flat workpiece, into which a bushing is inserted. A flange is formed on one end of the bushing.
- the length of the socket is greater than the length of the opening into which the socket can be inserted until the flange is placed on the surface.
- the shape of the opening in the workpiece corresponds to the polygonal outer surface.
- the bush has a cylindrical inner bore.
- DE 102012 206 257 A1 discloses an arrangement for fastening a roller, in particular a cam roller.
- the roller is rotatably mounted with an axis in a receptacle of a connecting structure.
- the axle has a pin for engaging in the receptacle of the connecting structure.
- at least one fastening element is provided, which can be screwed axially into the axle and interacts with the pin at a clamping connection. By screwing in the fastening element, the pin and fastening element are axially braced on the clamping connection, with the clamping connection being expanded in the receptacle.
- the disadvantage of the prior art is that it is expensive to establish a coaxial connection between a drive wheel and a drive lever via a coupling unit which can be inserted into an opening in the drive wheel and also powers and/or connects the drive wheel to the drive lever is positively connected. Furthermore, the play between the drive wheel and the drive lever cannot be designed to be easily adjustable, with a torque-limiting effect being achieved at the same time.
- the present invention relates to a coupling arrangement for the coaxial connection of a drive wheel and a drive lever, the drive lever having a coupling unit which can be inserted into a receiving opening of the drive wheel.
- the coupling unit of the drive lever can be non-positively and positively connected in the receiving opening of the drive wheel by means of a connecting means which runs centrally and axially to the receiving opening of the drive wheel and is arranged in the coupling unit.
- possible play between the drive wheel and the drive lever can be designed to be compensated for or completely prevented by the connecting means and the positive and non-positive connection.
- the connecting means is a screw which, when screwed in, forms a thread with a material-displacing effect formed in the coupling unit and/or the drive wheel and the coupling unit widens radially directly or indirectly in the receiving opening.
- the material-displacing effect of the screw creates a frictional connection between the coupling unit and the receiving opening.
- the design of the connecting means as a screw and the formation of a thread when screwing in also makes it possible to retighten or change the screw later and at the same time a reversible connection between the coupling unit and the receiving opening is made possible, so that both the drive wheel and the drive lever after assembly are detachably connected to each other and a later exchange is possible.
- the drive wheel has teeth on its outer edge.
- the drive wheel can be mechanically contacted or coupled to other gear wheels.
- other forms of drive are conceivable, such as belts, chains or other levers and linkages.
- the receiving opening of the drive wheel is arranged centrally in or on the drive wheel.

- the receiving opening is arranged or has an opening on only one side of the drive wheel and/or that the receiving opening is formed on or in the drive wheel.
- the receiving opening By arranging the receiving opening on one side of the drive, it is possible to install the drive wheel flat and in relative proximity to other components in a larger device or to design the drive wheel itself narrowly. Due to the arrangement and the associated possible dimensioning of the receiving opening, the drive wheel and in particular the receiving opening can be dimensioned appropriately for corresponding mechanical requirements.
- the receiving opening of the drive wheel is designed as a blind hole, also known as a blind hole.
- This configuration prevents the coupling unit or the screw arranged in the coupling unit or the connecting means from being able to reach through the drive wheel itself and thus damage other components of the drive device.
- the receiving opening has the shape of a polygon or a non-convex or convex regular polygon.
- the configuration of the receiving opening and its shape it is possible to dimension the receiving opening to the mechanical forces occurring in the drive device and at the same time to prevent components other than the associated drive lever with its coupling unit from being inserted into the receiving opening.
- the receiving opening has a star shape or has the shape of a tetragon, a pentagon, a hexagon, a heptagon, an octagon, a nonagon, a decagon or a hendecagon or a dodecagon.
- the coupling unit viewed in cross section, has a shape that is congruent to the shape of the receiving opening or has a shape that can be inserted into the receiving opening with a positive fit.
- the coupling unit is formed by at least two housing walls.
- the coupling unit can be widened and the shape of the coupling unit can be adapted to the shape of the receiving opening.
- the coupling unit by means of the screw is frictionally connected to the drive wheel in the receiving opening.
- a slipping clutch By choosing a frictional connection between the drive wheel and drive lever, a slipping clutch can be implemented, since torques can only be directly transmitted up to a torque effect that does not exceed the frictional connection. With a higher torque effect, this is no longer transmitted to the drive wheel, but the coupling unit slips through in the receiving opening.
- the coupling unit can be fixed in the receiving opening in a non-positive and/or positive manner via the at least two housing walls by means of the screw.
- the coupling unit has a through-opening into which the screw can be inserted, and that in the through-opening there is a step that narrows the through-opening and on which the screw head of the screw rests, so that when the screw is screwed in, the tapered stage of the coupling unit expands and the coupling unit clamped or wedged in the receiving opening.
- the screw to be inserted lies with the screw head on the tapered step, which narrows the through hole, and when the screw is screwed in, the screw head displaces the material of this tapering step in the direction of the receiving opening and clamps or wedges the coupling unit in the receiving opening.
- a hollow rivet is inserted in the through-opening of the coupling unit, with the screw thread fitting through the hollow rivet, but the screw head resting on the hollow rivet, so that when the screw is screwed in, it squeezes the hollow rivet and the squeezed hollow rivet dies Coupling unit expands and jammed in the receiving opening.
- the screw to be inserted rests with the screw head on the tubular rivet, which is located in the through opening, and when the screw is screwed in, the screw head displaces or squeezes the material of the tubular rivet and uses it to push the coupling unit apart or widens the coupling unit in the direction of the Receiving opening and clamped or wedged the coupling unit in the receiving opening.
- a rivet can also be used instead of a tubular rivet.
- a bushing or an intermediate lining is inserted in the through-opening of the coupling unit, with the screw thread fitting through the bushing or the intermediate lining, but the screw head resting on the bushing or the intermediate lining, so that when the screw is screwed in this crushes the bush or intermediate lining and the crushed beech or intermediate lining the Coupling unit expands and jammed in the receiving opening.
- the screw to be inserted rests with the screw head on the bushing or intermediate lining, which is located in the through opening, and when the screw is screwed in, the screw head displaces or squeezes the material of the bushing or intermediate lining and presses with it the coupling unit apart or widens the coupling unit in the direction of the receiving opening and clamps or wedges the coupling unit in the receiving opening.
- fins are arranged in the through-opening in such a way that the fins are arranged symmetrically to one another in the through-opening and the screw thread fits between the fins, but the screw head rests on the fins, so that when screwing in the Screw that squeezes the fins and the squeezed fins expand the coupling unit and jam in the receiving opening.
- the screw to be inserted rests with the screw head on the fins, which are arranged in the through-opening.
- the screw thread fits between the fins.
- the screw head displaces or squeezes the fins and uses them to push apart the coupling unit or widens the coupling unit in the direction of the receiving opening and clamps or wedges the coupling unit in the receiving opening.
- the screw has a conical screw head has, which spreads open the coupling unit when screwing in the screw and clamped in the receiving opening.
- the intensity of the frictional connection between the coupling unit of the drive lever and the receiving opening of the coupling unit can be adjusted and varied by the torque used when screwing in the screw.
- the force by which the coupling unit is clamped in the receiving opening is specified via the torque used to screw in the screw. The more torque the screw is screwed in, the more the coupling unit is deformed, which then leads to the force with which the coupling unit is clamped in the receiving opening increasing.
