Abstract:
A multi-speed transmission (01) having a px and having a zx is described. The px is equipped with a sun wheel (84) and at least one planet wheel (08). The cycloidal gear stage equipped with a ring gear (02) with a ring gear axis (20), at least one cycloidal disk (05, 06) rolling in the ring gear, with at least one off-center opening and with a number, equivalent to the number of planet wheels (08), of shared off-center eccentric shafts (03), each connected nonrotatably with a planet wheel (08) and located jointly rotatably around the ring gear axis (20) and having a number of eccentric portions (31, 32), equivalent to the number of vbs (05, 06), which are each supported rotatably in a respective off-center opening of the at least one cycloidal disk (05, 06). The transmission (01) is distinguished by a support of its gear stages relative to the ring gear (02), also called and/or capable of being called a load-bearing body and being for instance at least a part of its machine frame, with bearing elements located exclusively on one side of the ring gear (02). First molding surfaces (33) are embodied on the eccentric shafts (03), and second molding surfaces (82) are embodied on the planet wheels (08), with which molding surfaces the planet wheels (08) mesh with the first molding surfaces (33) on the eccentric shafts (03).
