Abstract

The invention is based on a hand-held power tool device equipped with a locking device. The locking device is provided for locking an output device and has at least one locking element for supporting at least one radial clamping force. According to a proposed embodiment, the locking element is provided to fasten and/or axially secure at least one component.

First claim

The invention claimed is:

1. A hand-held power tool device, comprising:
an output device including an output shaft;
a locking device adapted to lock the output device, the locking device including at least one locking element and at least one clamping element, the at least one locking element adapted to support at least one radial clamping force and the at least one clamping element arranged between the at least one locking element and the output shaft of the output device, wherein the at least one clamping element is embodied as a roller and acts directly on the output shaft;
wherein the locking device further includes a catch device which is embodied in one piece with a planet carrier of a planetary gear;
a pivot bearing unit that supports the output device and includes at least one bearing component which is fastened and/or axially secured by the at least one locking element, wherein the bearing component is directly fastened to the at least one locking element via a press-fit connection into a recess of the locking element.

2. The hand-held power tool device according to claim 1 , wherein the locking element directly supports the output shaft.

3. The hand-held power tool device as recited in claim 2 , wherein the locking element is at least partially manufactured out of a sintered material.

4. The hand-held power tool device according to claim 1 , having a housing unit in which the locking element is supported with a radial play of less than 0.1 mm.

5. The hand-held power tool device according to claim 2 , having a housing unit in which the locking element is supported with a radial play of less than 0.1 mm.

6. The hand-held power tool device according to claim 3 , having a housing unit in which the locking element is supported with a radial play of less than 0.1 mm.

7. The hand-held power tool device according to claim 1 , wherein a housing unit is molded around the locking element.

8. The hand-held power tool device according to claim 2 , wherein a housing unit is molded around the locking element.

9. The hand-held power tool device according to claim 3 , wherein a housing unit is molded around the locking element.

10. The hand-held power tool device according to claim 4 , wherein a housing unit is molded around the locking element.

11. The hand-held power tool device according to claim 1 , wherein the bearing component and the locking element are situated in at least one common plane extending perpendicular to a rotation axis of the pivot bearing unit.

12. The hand-held power tool device according to claim 10 , wherein the bearing component and the locking element are situated in at least one common plane extending perpendicular to a rotation axis of the pivot bearing unit.

13. The hand-held power tool device according to claim 1 , wherein the locking element axially secures at least one output shaft and/or at least one adjusting element.

14. A hand-held power tool equipped with a hand-held power tool device as recited claim 1 .

15. The hand-held power tool device according to claim 1 , wherein the bearing component is situated completely inside an axial region defined by the locking element.

16. The hand-held power tool device according to claim 1 , wherein the pivot bearing comprises an inner bearing ring which serves as an axial stop element for the at least one clamping element.

17. The hand-held power tool device according to claim 1 , wherein the at least one clamping element is capable of being carried along by the catch device.
