DUAL HARMONIC GEAR DRIVE Russian patent published in 2018 - IPC F16H1/32 

Abstract RU 2668455 C2

FIELD: instrument engineering.

SUBSTANCE: invention relates to the wave gear transmission. Wave gear transmission comprises two gear wheels, the flexible external gearing gear wheel, the wave generator for bending the gear wheel. External gearing gear ring of the dual wave gear transmission is equipped with the first and the second outer teeth (7, 8), which have a different number of teeth, and bends in order to obtain an ellipsoidal waveform by the wave generator. When t(1) is the thickness of the rim wall at the root of the tooth of the first outer teeth (7), and t (2) is the thickness of the rim wall at the root of the tooth of the second outer teeth (8), the ratio t(1) / t(2) is set by the value, which satisfies the inequality 0.5 > t(1) / t(2) < 1.5. In the dual wave gear transmission, the first and the second outer teeth, which have a different number of teeth, can be suitably bent, forming an engagement with the corresponding gears of internal gearing.

EFFECT: expansion of the application field is achieved.
