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 radially uninterrupted threaded bore, into which a screw part is screwed, in particular a threaded pin, which exerts pressure on the adapter shaft. A cylinder bolt is accommodated in a first, in particular radially directed, recess of the clamping ring, which projects radially inward into a second, in particular radially directed, recess introduced into the adapter shaft, in particular projects into it, especially in order to form a protection against loss and an anti-rotation protection acting in the axial direction and in the circumferential direction.

First claim

The invention claimed is:

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 including a radially uninterrupted threaded bore into which a screw part is screwed, the screw part adapted to exert pressure on the adapter shaft; and
a circular cylindrical disk accommodated in a first recess of the clamping ring, the disk adapted to project radially inwardly into a second recess of the adapter shaft to form a protection against loss and an anti-rotation protection acting in an axial direction and in a circumferential direction;
wherein the first and second recesses are arranged as blind recesses.

2. The assembly according to claim 1 , wherein the screw part includes a threaded pin.

3. The assembly according to claim 1 , wherein the screw part is adapted to exert pressure on a flattened area of the adapter shaft.

4. The assembly according to claim 1 , wherein the adapter shaft includes axial slots, axial slots that are set apart from one another in the circumferential direction, and/or axial slots that are set apart from one another at regular intervals in the circumferential direction.

5. The assembly according to claim 4 , wherein the second recess overlaps with one of the axial slots.

6. The assembly according to claim 5 , wherein a region axially covered by the second recess overlaps with a region axially covered by the axial slot and/or a region covered by the second recess in the circumferential direction overlaps with the region covered by the axial slot in the circumferential direction.

7. The assembly according to claim 4 , wherein the axial slots at an axial end of the adapter shaft lead into ambient air.

8. 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.

9. The assembly according to claim 8 , wherein the shaft is arrangeable coaxially with the adapter shaft.

10. The assembly according to claim 1 , wherein the first recess and the bore are arranged diametrically opposite each other.

11. The assembly according to claim 10 , wherein centers of gravity and/or center points of the first recess and the bore have a distance of 180° in the circumferential direction.

12. The assembly according to claim 1 , wherein the adapter shaft includes a chamfer and/or a lead-in bevel in an axial end region and between the second recess and the axial end of the adapter shaft that leads to the second recess when the clamping ring is mounted on the circular cylindrical disk.

13. The assembly according to claim 1 , wherein, in an axial region between a region axially covered by the second recess and an axial end of the adapter shaft, the adapter shaft has a radially smaller extension in a region covered by the second recess in the circumferential direction than in a diametrically opposite region, in any other diametrically opposite region, and/or in the circumferential direction.

14. The assembly according to claim 1 , wherein a maximum radial distance of the adapter shaft in an axial region between a region axially covered by the second recess and an axial end of the adapter shaft increases from a region covered by the second recess in the circumferential direction to a region covered by the first recess in the circumferential direction.

15. The assembly according to claim 1 , wherein the first recess is rectangular and/or is tangentially aligned, and/or the second recess is rectangular and/or includes a circular blind bore that does not extend through the adapter shaft.

16. The assembly according to claim 1 , wherein the adapter shaft includes a chamfer and/or a lead-in bevel that covers a circumferential angular range in the circumferential direction that includes a circumferential angular range covered by the second recess, and, set apart from the chamfer and/or bevel in the circumferential direction, a bead is provided on the adapter shaft that covers an axial region that includes an axial region covered by the chamfer and/or bevel.

17. The assembly according to claim 16 , wherein the region covered by the bead in the circumferential direction includes a region covered by a flattened area, of the adapter shaft, in the circumferential direction.

18. The assembly according to claim 16 , wherein a radial distance region covered by the chamfer and/or bevel is located radially within a radial distance region covered by the bead and/or radially adjoins it in the radially inward direction.

19. The assembly according to claim 1 , wherein a characteristic of a maximum radial distance of the adapter shaft in the axial direction has a local minimum in the axial region covered by the second recess.

20. The assembly according to claim 1 , wherein a region axially covered by the first recess overlaps with a region axially covered by the second recess.

21. The assembly according to claim 1 , wherein a region covered by the first recess in the circumferential direction overlaps with a region covered by the second recess in the circumferential direction.

22. 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 including a radially uninterrupted threaded bore into which a screw part is screwed, the screw part adapted to exert pressure on the adapter shaft; and
a circular cylindrical disk accommodated in a first recess of the clamping ring, the circular cylindrical disk adapted to project radially inwardly into a second recess of the adapter shaft to form a protection against loss and an anti-rotation protection acting in an axial direction and in a circumferential direction.

23. A device, comprising:
an adapter shaft;
a 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, the shaft being inserted into the adapter shaft, the clamping ring including a radially uninterrupted threaded bore into which a screw part is screwed, the screw part exerting pressure on the adapter shaft; and
a circular cylindrical disk accommodated in a first recess of the clamping ring, the disk projecting radially inwardly into a second recess of the adapter shaft to form a protection against loss and an anti-rotation protection acting in an axial direction and in a circumferential direction.

24. The device according to claim 23 , wherein the first and second recesses are arranged as blind recesses.
