ABSTRACT:
A roller-type drive somewhat similar to epicyclic gearing is provided wherein one of the three rollers present is a wedging roller which produces a tighter wedging action for all three planetary rollers in response to increasing torque. A stud or axle about which the wedging roller turns limits movement of the wedging roller and applies a drag thereto when a predetermined maximum torque is reached so that the drive begins to slip and does not exceed the predetermined torque desired.
