AUTOMATIC FRICTION VARIABLE SPEED DRIVE Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: automatic friction variable speed drive has housing with support surface, driving and driven shafts, intermediate solids of revolution coupled, respectively, with driving and driven members, pressure device and cage for accommodating solids of revolution in its sockets. Intermediate solids of revolution are brought into engagement with driving and driven members and support surface of housing. Pressure device is installed between driving shaft and driving member. Cage is coupled with driven shaft by flexible members one end of which is rigidly secured on driven shaft, and the other, on corresponding sockets of solid of revolution. Sockets for solids of revolution in cage are interconnected by flexible members. EFFECT: enlarged operating capabilities. 6 cl, 34 dwg
