Abstract

In an assembly for connecting an adapter shaft to a shaft in a force-fitting manner using a clamping ring, the clamping ring is mounted on the adapter shaft, the shaft is inserted into the adapter shaft, the clamping ring has a first radially uninterrupted threaded bore into which a first screw part is screwed, in particular a first threaded pin, which exerts pressure on the adapter shaft, the clamping ring has a second radially uninterrupted threaded bore into which a second screw part is screwed, in particular a second threaded pin, and the second screw part projects at least partially into a recess of the adapter shaft and in particular exerts pressure on the adapter shaft.

Claims (31)

1. An assembly for connecting an adapter shaft to a shaft in a force-fitting manner, comprising:

a clamping ring adapted to be mounted on the adapter shaft, the shaft being insertable into the adapter shaft, the clamping ring having a first radially uninterrupted threaded bore and a second radially uninterrupted threaded bore;

a first screw part screwed into the first uninterrupted threaded bore and adapted to exert pressure on the adapter shaft; and

a second screw part screwed into the second radially uninterrupted threaded bore, at least partially projecting into a recess of the adapter shaft, and adapted to exert pressure on the adapter shaft;

wherein the adapter shaft includes axial slots set apart from one another at regular intervals in a circumferential direction; and

wherein a region covered by the recess in a circumferential direction encompasses a region covered by a first one of the axial slots in the circumferential direction.

2. The assembly according to claim 1 , wherein at least one of the screw parts includes a threaded pin.

3. The assembly according to claim 1 , wherein the axial slots are radially uninterrupted and/or terminate at a first axial end of the adapter shaft, the axial slots having an open configuration in a direction of the axial end of the adapter shaft, and leading into the environment and/or ambient air.

4. The assembly according to claim 1 , wherein the recess is arranged as a blind bore, as a radially directed blind bore introduced from radially outside, and/or to not radially extend through a wall of the adapter shaft.

5. The assembly according to claim 1 , wherein a surface region of the adapter shaft on which the first screw part is adapted to exert pressure is located diametrically opposite the recess, in a circumferential direction on the adapter shaft.

6. The assembly according to claim 5 , wherein a region axially covered by the surface region overlaps and/or encompasses a region axially covered by the recess.

7. The assembly according to claim 1 , wherein a surface region of the adapter shaft onto which the first threaded pin is adapted to exerts pressure is arranged as a flattened region and/or a flattened region that is tangentially aligned with respect to the adapter shaft.

8. The assembly according to claim 7 , wherein the flattened region is aligned perpendicular to a radial direction.

9. The assembly according to claim 7 , wherein a normal to the flattened region extends in a radial direction.

10. The assembly according to claim 7 , wherein the flattened region is aligned perpendicular to a radial direction that is aligned parallel to a normal direction of the flattened region.

11. The assembly according to claim 1 , wherein the axial slots are radially uninterrupted and/or terminate at a first axial end of the adapter shaft into the environment.

12. The assembly according to claim 1 , wherein the shaft is insertable into a region of the adapter shaft that is arranged as a hollow shaft region and/or is arranged coaxially with the adapter shaft.

13. The assembly according to claim 11 , wherein the axial slots have an open configuration in a direction of an axial end of the adapter shaft and lead into the environment and/or ambient air.

14. The assembly according to claim 1 , wherein region covered by the recess in an axial direction is encompassed by a region covered by the axial slot in the axial direction.

15. The assembly according to claim 1 , wherein a diameter of the first threaded pin is at least three times larger than a diameter of the second threaded pin and/or a diameter of the first threaded bore is at least three times larger than a diameter of the second threaded bore.

16. The assembly according to claim 1 , wherein the adapter shaft includes a chamfer and/or a lead-in bevel in an axial end region.

17. The assembly according to claim 1 , wherein the clamping ring includes a lead-in bevel in an axial end region.

18. A device, comprising:

an adapter shaft;

a shaft inserted into the adapter shaft; and

an assembly adapted to connect the adapter shaft to the shaft in a force-fitting manner, the assembly including:

a clamping ring mounted on the adapter shaft and including a first radially uninterrupted threaded bore and a second radially uninterrupted threaded bore;

a first screw part screwed into the first radially uninterrupted threaded bore and exerting pressure on the adapter shaft; and

a second screw part screwed into the second radially uninterrupted threaded bore, at least partially projecting into a recess of the adapter shaft, and exerting pressure on the adapter shaft;

wherein the adapter shaft includes axial slots set apart from one another at regular intervals in a circumferential direction; and

wherein a region covered by the recess in a circumferential direction encompasses a region covered by a first one of the axial slots in the circumferential direction.
