Abstract

A type series of gear-side motor end shields for an angle geared motor is disclosed, with the angle geared motor including a gear housing of an angle gear, in which a toothed wheel is mounted to rotate about a gear shaft axle, and a stator housing of an electric motor, in which stator housing a motor shaft is rotatably mounted. Each of the gear-side motor end shields includes a gear-side section for securement of the gear housing, and a motor-side section which is permanently connected to the gear-side section for securement of the stator housing. The gear-side motor end shields are configured such that each of the gear-side motor end shields produces a different axial offset between the gear shaft axle and an axle of the motor shaft.

First claim

The invention claimed is:

1. A kit of gear-side motor end shields for an angle geared motor, said angle geared motor comprising a gear housing of an angle gear, in which a toothed wheel is mounted to rotate about a gear shaft, axle, and a stator housing of an electric motor, in which stator housing a motor shaft is rotatably mounted, each of the gear-side motor end shields comprising:
a gear-side section for securement of the gear housing; and
a motor-side section permanently connected to the gear-side section for securement of the stator housing,
wherein the gear side motor, end shields are configured such that each of the gear-side motor end shields produces a different axial offset between the gear shaft axle and an axle of the motor shaft,
wherein at least one of the gear-side motor end shields is configured to produce a first axial offset in a first assembly position and a second axial offset in a second assembly position when the motor end shield is rotated by about 180 degrees around the axle of the motor shaft, said second axial offset being different from the first axial offset.

2. The kit of claim 1 , wherein the toothed wheel meshes with a pinion fastened to the motor shaft.

3. A gear-side motor end shield for an angle geared motor, said angle geared motor comprising a gear housing of an angle gear, in which a toothed wheel is mounted to rotate about a gear shaft axle, and a stator housing of an electric motor, in which stator housing a motor shaft is rotatably mounted, said gear-side motor end shield comprising:
a gear-side section for securement of the gear housing; and
a motor-side section permanently connected to the gear-side section for securement of the stator housing,
wherein the gear-side motor end shield is configured to produce a first axial offset between the gear shaft axle and an axle of the motor shaft in a first assembly position between the gear housing and the stator housing, and to produce a second axial offset between the gear shaft axle and the axle of the motor shaft in a second assembly position between the gear housing and the stator housing when the motor end shield is rotated by about 180 degrees around the axle of the motor shaft, said second axial offset being different from the first axial offset.

4. The gear-side motor end shield of claim 3 , wherein the toothed wheel meshes with a pinion fastened to the motor shaft.
