Abstract
The utility model relates to a large-reduction-ratio angular harmonic speed reduction device which comprises a casing and two harmonic speed reducers arranged in the casing, namely the first harmonic speed reducer and the second harmonic speed reducer. Each harmonic speed reducer comprises a rigid wheel with inner teeth, a flexible gear and a generator with an oval cross section, wherein the rigid wheel is fixedly arranged in the casing, the generator is rotatably arranged in the casing, the flexible gear rotatably sleeves the generator through a flexible bearing and deforms with the generator so as to be oval, and two ends of the flexible gear corresponding to the long oval shaft end are meshed with the inner teeth of the rigid wheel. The flexible gear of the first harmonic speed reducer is in transmission connection with the generator of the second harmonic speed reducer. The harmonic speed reducers are connected in series to enable the reduction ratio to be greatly improved, and corresponding usage requirements are met. Due to the fact that a spiral gear is arranged between two harmonic speed reducers, the large-reduction-ratio angular harmonic speed reduction device can meet the angular transmission demand in any transmission direction at angles ranging from 90 degrees to 180 degrees.
