The invention is a compact gear drive with a maximum transmission range for a constant crown gear diameter and constant axial displacement. A pinion is mounted on a bearing remote from the crown gear. The pinion is constructed as a hollow shaft and is fictionally connected to a drive shaft of a driving motor.
Claims19
A motor assembly comprising:
- a motor having a drive shaft which rotates during activation of the motor;
- a gear housing attached to the motor;
- a gear and a pinion meshing with the gear, the gear and the pinion being located within the gear housing with the gear driving a power takeoff;
- and
- a bearing, mounted in the gear housing at a position displaced from the toothed gear, for rotatably supporting rotation of the pinion during activation of the motor;
- and wherein
- the pinion has a hollow shaft with the hollow shaft engaging an outside surface of the drive shaft for directly driving the pinion.
