Abstract
In a gear unit that includes a rotatably mounted toothed part and a method for manufacturing a gear unit that includes a toothed part, the toothed part has bearing seats and a toothing, and the toothed part, e.g., together with the toothing, is produced from sintered metal powder. The toothed part is, for example, arranged as one piece, e.g., in an integral fashion.
Claims36
A gear unit, comprising:
- a rotatably mounted toothed part including bearing seats and a toothing, the toothed part being formed of sintered metal powder;
- wherein the toothing is arranged as a plane toothing;
- wherein the toothing has a first chamfer area at an outer edge in a radial direction;
- and
- wherein at each circumferential position and/or at each circumferential angular position, the first chamfer area has an angle amount in relation to an axial direction between 10° and 30° and/or between 15° and 25°.

A gear unit, comprising:
- a rotatably mounted toothed part including bearing seats and a toothing, the toothed part being formed of sintered metal powder;
- wherein the toothing is arranged as a plane toothing;
- wherein a transition region is arranged between a region covered by the toothing in an axial direction, an outer radius measured in a radial direction and/or a diameter increasing in a strictly monotonic and continuously differentiable manner with decreasing distance from the toothing;
- and
- wherein resting against a step of the toothed part, axially set apart from the toothing and disposed on a side of the toothing axially facing away from the transition area, is a shim washer arranged axially between the step and an inner ring of a bearing, the shim washer contacting the inner ring.
