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

FIELD: mechanical engineering.

SUBSTANCE: invention can be used as drives of aircraft and rocket automatic mechanisms. Proposed harmonic drive has housing 1, electric motor 4, output shaft 3, harmonic gear train, n (n=1, 2, etc) planet pinions 15 and torque-limiting clutch 12 arranged in space of output shaft. Bearing 10 of torque-limiting clutch 12 is arranged between shaft 17 of torque-limiting clutch and output shaft 3. Housing 1 has cup 18 whose bottom is located inside flexible wheel 6. electric motor is arranged inside cup coaxially with torque-limiting clutch and is secured on its bottom. Wave generator 7 is secured on housing of torque-limiting clutch. Gear wheel 15 is secured on shaft of torque-limiting clutch. Second bearing 11 of torque-limiting clutch is installed between gear wheel 15 and bottom 19 of cup 18.

EFFECT: reduced axial dimensions, simplified design.
