Abstract
A planetary gearbox having two ring gears arranged in different planes, of which a first ring gear and a second ring gear are designed to mesh during operation with at least one planet gear of a respective planet gear set, wherein a thrust washer is arranged axially between the two ring gears and a first contact area for making contact with the first ring gear is present on the first end face for making contact with the second ring gear is present on the second end face.
Claims17
A planetary gearbox, comprising:
- first and second ring gears which are arranged in different planes;
- a planet gear set, the first ring gear and the second ring gear are designed to mesh, during operation, with at least one planet gear of the planet gear set;
- a thrust washer is arranged axially between the first and second ring gears, a first contact area on a first end face of the thrust washer is configured for making contact with the first ring gear and a second contact area on a second end face of the thrust washer is configured for making contact with the second ring gear;
- the first ring gear has a first outer diameter that is smaller than a second outer diameter of the second ring gear;
- and
- the thrust washer has a first bend and a second bend, such that the first contact area adjoins a radially inner edge of the thrust washer and the second contact area adjoins a radially outer edge of the thrust washer.
