The invention discloses a cosine involute small-tooth-difference transmission device capable of being used for a robot joint reducer. The cosine involute small-tooth-difference transmission device is composed of a high-speed-level sun wheel, a high-speed-level planet wheel, a planet wheel bearing, an eccentric shaft, a planet wheel gasket, a high-speed-level inner gear, a left end cover, a left end cover screw, a left end cover seal, a sealing seat screw, a sealing seat, a sealing seat gasket, an output shaft left rolling body, a low-speed-level inner gear, an output shaft right rolling body, a right end cover screw, a right end cover, an output shaft right cover, a low-speed-level right planet wheel, an output shaft rod penetrating assembly, an output shaft end cover plate, a low-speed-level left planet wheel, a right seal, an eccentric shaft right bearing rolling body, a left eccentric bearing rolling body, a right eccentric bearing rolling body and an eccentric shaft left bearing rolling body. The cosine involute small-tooth-difference transmission device is a novel precise reducer which is formed by changing the tooth profile of small tooth difference transmission based on planet gear transmission and small-tooth-difference transmission, and the cosine involute small-tooth-difference transmission device can serve as part or the whole of a robot joint reducer and a wind power generation speed increaser.
Description
technical field [0001] The invention relates to a cosine involute less-tooth-difference transmission device that can be used in a robot joint reducer. The novel precision reducer belongs to the technical field of mechanical transmission, and can be used as a part or all of a robot joint reducer and a wind power speed increaser. Background technique [0002] The precision, stiffness, efficiency, and volume of robot reducers have an important impact on its working performance. This type of reducer requires a large transmission ratio, generally above 100. If a planetary reducer is directly used, three-stage reducers are usually required in series. The advantage of the involute planetary reducer is that the transmission efficiency is very high, but the disadvantage is that the number of parts is large, which affects the reduction of volume and cost. Therefore, at present, the harmonic reducer and the planetary reducer with small tooth difference are mainly used. The former is su...
