Abstract

The invention is based on a power tool, in particular an angle grinder, having a motor and a gear. It is proposed that the motor and/or the gear is embodied as a mountable function module.

Claims

1. A power tool, in particular an angle grinder, having a motor and a gear, characterized in that the motor and/or the gear is embodied as a mountable function module.

2. The power tool of claim 1, characterized in that the gear is embodied as a mountable function module, with a gear input shaft supported in a gearbox.

3. The power tool of claim 2, characterized in that the gear input shaft is supported two-fold in the gearbox.

4. The power tool of claim 2 or 3, characterized in that the gear input shaft is fixed in the gearbox via at least one detent connection.

5. The power tool of claim 4, characterized in that the gear input shaft is fixed via a unit that is fixed in a gearbox via a detent connection.

6. The power tool of claim 5, characterized in that the gear input shaft is fixed via a detent connection in the unit fixed in the gearbox.

7. The power tool of one of the foregoing claims, characterized by the embodiment of the electric motor as a mountable function unit, which is supported in the housing via a damping unit.

8. The power tool of claim 7, characterized in that the damping unit forms at least one part of a compensation coupling.

9. The power tool of claim 7 or 8, characterized in that the damping unit includes at least one rubber ring.

10. The power tool of one of the foregoing claims, characterized in that the motor and the gear are connected via a coupling.

12. The power tool of claim 10 or 11, characterized in that the coupling is embodied at least partially integrally with a fan.

16. A coupling for connecting a motor and a gear of a power tool of one of claims 1 through 12.

17. The coupling of claim 16, characterized by the at least partially integral embodiment with a fan.

11. The power tool of claim 11, characterized in that the motor and the gear are connected via a male coupling.

13. An angle grinder gear having a gearbox, characterized by its embodiment as a function module.

14. The angle grinder gear of claim 13, characterized by a gear input shaft supported two-fold in the gearbox.

15. The angle grinder gear of claim 14, characterized in that the gear input shaft is fixed in the gearbox via at least one detent connection.
