Abstract

The invention relates to a cycloidal planetary gear speed reducer having a central shaft, comprising at least one ring gear disposed so as to be rigidly mounted in a housing, a set of planet gears in mesh with the ring gear, a rotatably supported planet gear carrier, on which the planet gears are mounted, and a plurality of drive plates arranged axially one behind the other in order to drive the planet gears, wherein the drive plates are mounted eccentrically on the central shaft in order to execute a circular translation movement, wherein at any given time during execution of a circular translation movement, the drive plates are in engagement with at least two planet gears.
