FIELD: machine engineering.
SUBSTANCE: frictional planetary gear unit comprises a housing, the wheels and the carrier discs. The stationary central wheel is kept from turning by frictional interaction with a spring wound outside the fixed central wheel, one end of which is fixed in the body. The rotation of the central rotor is transmitted satellites, which axles are inserted into the slots of the guide and drive roll on the inner surface of the stationary central wheel angle cut.
EFFECT: increased service life of the gearbox.
