Abstract
The invention relates to a planetary gear with little play that comprises, for one stage of reduction each, at least one sun wheel, an elastically deformable internal geared wheel, planet wheels that are rotatably received by a planetary carrier and that act on the one hand on the sun wheel and on the other hand on the internal geared wheel, thereby transmitting power, and a housing. The aim of the invention is to provide a planetary gear that is simple in design and reliable in operation. To this end, the elastically deformable internal geared wheel is configured as an outer wall zone of the housing.
