Planetary gear for use in e.g. coreless motor, has tooth arrangement provided between wheels and/or ring gears for supporting moment against pitching, where position of arrangement is different from positions of other tooth arrangements

摘要

The gear (1) has a tooth arrangement provided between planetary wheels (7) and sun wheels (5, 6) and/or ring gears (13, 14) for supporting moment against pitching around a tilting axis (9) standing vertical to axles (8) of the planetary wheels. An axial position of the tooth arrangement is different from axial positions of other tooth arrangements. A driven shaft of the gear is connected with one of the ring gears. The other ring gears are firmly connected with a gear housing. One of the sun wheels is connected with the drive shaft in a torque-proof manner. . An independent claim is also included for an electric motor comprising a planetary gear.
