Abstract
The epicyclic drive unit has the friction ring (5) prestressed in the radial direction to transmit the torque, and acting as the sun wheel or annulus. The amount of stress can be adjustable being applied by oil or pneumatic pressure. The ring can be of thin steel, inserted in an elastic ring of rubber or plastics to grip the planetary rollers (3) running against the periphery of the sun wheel (1).
