Abstract

Receiving arrangements for receiving camshafts and methods for grinding machining camshafts may be used with camshafts that have a shaft body that extends along an axis of rotation and includes functional elements. A gearwheel may be mounted on the shaft body, wherein a receiving body is provided, by means of which the camshaft can be at least partially received for purposes of performing a grinding machining process. The gearwheel may include a receiving means onto which the receiving body can be engaged and by way of which it is made possible for the camshaft to be received by the receiving body.

First claim

What is claimed is:

1. A combination of a workpiece, a workpiece holder, and a gearwheel, the combination comprising:
a camshaft configured as the workpiece, the camshaft including a shaft body that extends along an axis of rotation and includes functional elements;
the gearwheel, which is mounted to the shaft body of the camshaft, the gearwheel including receiving means and teeth, wherein the receiving means of the gearwheel comprises a collar with an annular conical recess that is inward facing with respect to the gearwheel, wherein the collar is integral with the gearwheel and concentrically positioned about the axis of rotation; and
a receiving body configured as the workpiece holder, wherein the camshaft is at least partially received in the receiving body, wherein the receiving body is disposed farther from an axial midpoint of the shaft body than the gearwheel, wherein the receiving means of the gearwheel is engaged with the receiving body, wherein the receiving body comprises a receiving formation that is of a complimentary form to the annular conical recess of the collar of the gearwheel and which is engageable onto the annular conical recess of the collar.

2. The combination of claim 1 wherein a longitudinal extent of the shaft body in a direction of the axis of rotation protrudes axially beyond a position of the gearwheel on the shaft body such that the gearwheel is spaced apart from an axial end of the shaft body, the axial end of the shaft body being disposed within the receiving body.

3. The combination of claim 1 wherein an end of the receiving body comprises a cavity, wherein an end of the shaft body is received in the cavity of the receiving body.

4. The combination of claim 1 wherein at least one of the functional elements is a bearing element.

5. The combination of claim 1 wherein the collar on the gearwheel extends away from the axial midpoint of the shaft body towards the receiving body.

6. The combination of claim 1 wherein an end of the shaft body proximal the receiving body protrudes axially beyond an entirety of the gearwheel such that the gearwheel is spaced axially apart from the end of the shaft body proximal the receiving body.

7. The combination of claim 1 wherein the receiving body encircles and encloses an end of the shaft body.

8. The combination of claim 1 wherein at least a portion of the receiving body is spaced axially apart from an end of the shaft body proximal the receiving body.

9. The combination of claim 1 wherein a first portion of the receiving body protrudes axially away from the shaft body and a second portion of the receiving body overlaps axially with the shaft body.

10. The combination of claim 1 wherein the collar is disposed on a side of the gearwheel that faces away from the axial midpoint of the shaft body.

11. The combination of claim 1 wherein the gearwheel includes a through-hole, wherein the camshaft extends through the through-hole of the gearwheel and at least partially into the receiving body.

12. The combination of claim 1 wherein the teeth extend about an entirety of a circumference of the gearwheel.

13. A workpiece and holder combination comprising:
a workpiece having a shaft body including functional elements, wherein the shaft body extends along an axis of rotation; and
a gearwheel having teeth mounted on the shaft body, the gearwheel having a receiving means that is engageable with a workpiece holder receiving body and that permits the camshaft to be received by the workpiece holder receiving body, wherein the receiving means of the gearwheel comprises a collar with an annular conical recess that is inward facing with respect to the gearwheel, wherein the collar is integral with the gearwheel and concentrically positioned about the axis of rotation,
wherein the workpiece holder receiving body serves as a workpiece receiving arrangement during grinding machining of at least one of the functional elements, wherein the receiving body comprises a receiving formation that is of a complimentary form to the annular conical recess of the collar of the gearwheel and which is engageable onto the annular conical recess of the collar.

14. The combination of claim 13 wherein the collar is formed integrally on the gearwheel at a hub side and positioned concentrically around the axis of rotation.

15. The combination of claim 13 wherein a longitudinal extent of the shaft body in a direction of the axis of rotation protrudes axially beyond a position of the gearwheel on the shaft body such that the gearwheel is received on the shaft body and is spaced apart from an axial shaft end of the shaft body.

16. The combination of claim 13 in the form of an assembled camshaft, wherein the shaft body, the gearwheel, and the functional elements are formed separately and then joined together.
