ABSTRACT:
A planetary gear system comprising housing, an input shaft at one end and an output shaft at the opposite end and transmission means drivingly connecting the shafts to one another. The transmission means includes a planet support having at least two planet wheel journals mounted therein. At least one of the journals mounts a planet friction wheel adapted to contact a friction ring having at least an elastically deformable portion. Means is provided for adjusting the pressure applying relation between the planet friction wheel and the elastically deformable portion of the friction ring. This arrangement provides a multiple step gear system wherein the play in the system is minimized and the system operates at low noise levels.
