Patent ID: 7568993

Claim:
A planetary gear train, comprising: a ring gear ( 14 ), a sun gear ( 4 ), and a plurality of planetary gears ( 8 ) rotatably mounted on a planetary gear carrier ( 18 ) by corresponding planetary gear axles ( 16 ), wherein each planetary gear ( 8 ) is in tooth contact with the ring gear ( 14 ) and the sun gear ( 4 ), the planetary gear axles ( 16 ) are mounted at an inclined angle (α) with respect to an axle ( 2 ) of the sun gear ( 4 ), each planetary gear ( 16 ) is axially displaceable upon the corresponding planetary gear axle ( 16 ), and the ring gear ( 14 ) and the planetary gears ( 8 ) are of conical design, and an adjusting mechanism is operatively situated between the planetary gear carrier ( 18 ) and the planetary gears ( 8 ) for adjusting a position of the planetary gears ( 8 ) on the planetary gear axles ( 16 ) for a backlash.
