Abstract
A reduction gear includes a housing (210) and gear stages with an externally toothed first gear wheel (240), and an internally toothed second gear wheel (260), meshing with the first gear wheel, and rotationally fixed to an output (270). The first gear wheel is moved circularly by an eccentric (226). A torque support disc prevents the first gear wheel rotating relative to the housing. The first gear wheel has a guide pin which engages in a guide groove of the torque support disc, or the torque support disc has a guide pin, which engages in a guide groove of the first gear wheel. The first gear wheel has a base body with a cam or the torque support disc has a base part with a cam which projects in the axial direction and contacts the torque support disc whereby the guide pin does not completely engage in the guide groove.
