GEAR-MOTOR DRIVE WITH INTEGRATED PRECESSING GEAR WHEEL (VERSIONS) Russian patent published in 2015 - IPC F16H1/32 H02K7/116 

FIELD: electricity.

SUBSTANCE: gear-motor drive comprises (1) a gear wheel (2) and inductance coils (10), and each coil has a movable core (11). The intermediate gear wheel (3) with tooth rings (4, 5) is fixed so that it ensures precessing motion of an auxiliary axis (7) placed by its first end in the body (2) and by the other end in the output shaft bore (9). The inductance coils (10) are placed in a circumferential direction in the peripheral part of the precessing gear wheel (3) with a gap between the butt end of the inductance coil and flat surface of the precessing wheel. The core (11) protrudes outside the butt end of the inductance coil (10) and in protruded state it is pressed to the flat surface of the precessing gear wheel. Gear rings of all gear wheels are equipped with end teeth. Versions of the gear-motor wheel with rigid core, inductance coils and ferromagnetic straps and the gear-motor wheel with permanent magnets and inductance coils are specified herein.

EFFECT: development of a new design for electric machine combining advantages of the butt electric motor and precessional planetary transmission.
