Abstract

A device for mounting at least one receiving element on a shaft may include at least one holder for holding a receiving element having a cut-out for receiving a shaft. A moveable guide slide may be configured to move the shaft in a first direction through the cut-out in the receiving element. A tailstock may be configured to move counter to the first direction. The tailstock may include a tailstock tip configured to couple to an end face of the shaft. A vibration generator may be arranged in the tailstock for vibrating the shaft.

First claim

The invention claimed is:

1. A device for mounting at least one receiving element on a shaft, comprising:
at least one holder for holding a receiving element, wherein the receiving element includes a cut-out for receiving the shaft;
a movable guide slide configured to move the shaft in a first direction through the cut-out in the receiving element;
a tailstock configured to move counter to the first direction, the tailstock including a to stock tip configured to couple to an end face of the shaft, the tailstock tip including an end bevel structured and arranged to couple the tailstock tip to the end face of the shaft when at least part of the end bevel is inserted within the shaft;
a vibration generator arranged within an interior cavity of the tailstock for vibrating the shaft and extending at least partially within the tailstock tip;
wherein the vibration generator is at least partially arranged in the tailstock tip adjacent to the end lever; and
wherein the vibration generator includes a driven eccentric.

2. The device according to claim 1 , wherein the at least one holder is displaceable in a plane extending transverse to an axis of the shaft.

3. The device according to claim 1 , wherein the end bevel has a cross-sectional area smaller than the cut-out in the receiving element such that the receiving element is alignable within the at least one holder when at least part of the end bevel is inserted within the cut-out.

4. The device according to claim 1 , wherein at least one of:
the vibration generator is configured to be switched on and off, and
the vibration generator is adjustable to vary at least one of a frequency of vibrations and an amplitude of vibrations.

5. The device according to claim 1 , wherein the at least one holder includes a plurality of holders arranged axially spaced apart relative to an axis of the shaft and each configured to hold a respective receiving element, and wherein the tailstock together with the vibration generator arranged therein are axially movable counter to the first direction and pass through the plurality of holders to facilitate aligning the respective receiving elements.

6. The device according to claim 1 , wherein the guide slide is configured to move linearly in the first direction towards the tailstock to push the shaft through the cut-out of the receiving element and the tailstock is configured to move linearly counter to the first direction towards the guide slide into the cut-out of the receiving element held by the at least one holder, and wherein the tailstock couples to the end face of the shaft via the tailstock tip.

7. The device according to claim 1 , wherein an outer diameter of the tailstock including the tailstock tip is smaller than an inner diameter of the cut-out in the receiving element.

8. The device according to claim 1 , wherein the eccentric is driven at least one of hydraulically, electrically, and pneumatically.

9. The device according to claim 1 , wherein the receiving element includes at least one of a cam, a balancing weight, a gear and a bearing.

10. The device according to claim 1 , wherein the tailstock tip is an elongated tubular portion of the tailstock.

11. The device according to claim 1 , wherein the interior cavity of the tailstock extends into the tailstock tip and defines an interior cavity of the tailstock tip, the vibration generator arranged within the interior cavity of the tailstock tip.

12. The device according to claim 8 , wherein the eccentric is an electric motor with an unbalanced mass.
