ABSTRACT:
A friction planetary transmission has a sun roller planetary roller and an elastically deformable outer periphery. The planetary rollers are attached to shafts which have a limited amount of radial movement. The outer periphery deforms to exert a frictional contact pressure on the planetary rollers such that a torque can be transmitted. The torque is adjustable by a circular disk which fits inside the outer periphery to regulate the amount of deformation. The circular disk can be moved axially to adjust the torque.
