Abstract

The invention relates to the field of mechanical transmission reducers, and discloses a real-time anti-backlash variable-radius corrugated-toothed reducer comprising a reducer body, an eccentric input shaft, a wave generator, a roller, a moving rod, a fixed wheel, an output shaft and screws. The roller, the wave generator and the fixed wheel form an engaged pair, the reducer body and the fixed wheel are in interference fit, the moving rod is connected to the roller radially, one end of the moving rod is connected to the output shaft axially, and the other end is connected to the eccentric input shaft through a shaft sleeve and a bearing axially. The real-time anti-backlash variable-radius corrugated-toothed reducer is characterized in that the outer circumferences of the wave generator and the roller are variable-radius curves, the inner circumference of the fixed shaft is a curve, the centers of the screws are provided with through holes, an anti-backlash power output device is arranged between the reducer body and the fixed wheel, and a wearing backlash eliminating mechanism is arranged between the fixed wheel and the roller, backlashes in the engaged pair are eliminated, anti-backlash transmission is achieved, and transmission accuracy and transmission efficiency of the mechanism are guaranteed.

Description

technical field [0001] The invention relates to a mechanical transmission device, in particular to a variable-diameter wave gear reducer. Background technique [0002] Planetary transmission with small tooth difference is widely used in various fields of industry. With the increasing demand for high-quality products, the requirements for high precision, high stability and high transmission efficiency are put forward for planetary transmission with small tooth difference. [0003] After the meshing pair of planetary transmission with small tooth difference wears out, there will be gaps, which will cause backlash in the reducer, which will not only affect the transmission accuracy of the system, but also reduce transmission efficiency and system dynamic stability, and affect the promotion and application of planetary transmission with small tooth difference . Contents of the invention [0004] In order to solve the problem that the transmission accuracy and transmission eff...
