WAVE DRIVE Russian patent published in 2006 - IPC F16H1/00 F16H57/02 

FIELD: mechanical engineering.

SUBSTANCE: wave drive comprises housing (1), output shaft (3), and wave gear with unmovable flexible wheel (5). Rigid wheel (6) is secured to output shaft (3) and wave generator (7) mounted inside flexible wheel (5). Flexible wheel (5) receives projection (8) of housing (1) with bore (9). Electric motor (11) is mounted on the face of the bore. The gearing wheel of wave generator (7) engages satellites (13). Satellite (13) engages pinion (14) mounted on the shaft of electric motor (11). From the side opposite to electric motor (11), face (15) of projection (8) of the housing is provided with pin (16). The pin and projection are axially aligned. Output shaft (3) is hollow and embraces the pin. Bearings (2) of the output shaft are interposed between its inner surface and outer surface of pin (16). Projection (8) of housing (1) has n grooves for receiving satellites (13).

EFFECT: reduced sizes and weight.
