Problems solved by technology
However, the general structure of the current movable gear reducer cannot eliminate the slipping phenomenon, and it cannot be used in mechanisms that require more precise transmission accuracy.
The patent document with the application number 200520126603.2 discloses a three-phase movable tooth device, which uses a three-phase cam as a shock wave device, which can achieve three shock wave effects, but the shock wave device cannot achieve two-stage transmission during the transmission process to reduce the speed It cannot be used in the mechanism that needs to distribute the transmission ratio reasonably, which affects the wide range of applications of the movable gear reducer

The invention relates to oscillating tooth transmission devices, in particular to a chain wheel shock wave push rod oscillating tooth two-stage speed reducer. The chain wheel shock wave push rod oscillating tooth two-stage speed reducer comprises a single-row chain wheel input shaft, a fixed chain disc, a bidirectional chain ring, chain disc push rod oscillating teeth, a center wheel and an oscillating tooth output shaft. According to the chain wheel shock wave push rod oscillating tooth two-stage speed reducer, the shock wave mode of a shock wave device in a traditional oscillating tooth structure is changed, the transmission part between a driving shaft and the shock wave device is replaced with a two-stage transmission structure composed of an eccentric chain wheel input shaft, the fixed chain disc and the bidirectional chain wheel, the bidirectional chain wheel rotates around the fixed chain disc so that three times of shock wave motion can be achieved, and the speed reduction effect is achieved; the shock wave device and the oscillating tooth part are replaced with the structure formed by the bidirectional chain ring and the chain disc, motion and power are transmitted throughengagement between the chain ring and the chain disc, the slipping phenomenon is avoided, and the even transmission precision and the working performance of the mechanism in a poor or severe environment are improved.
Description
technical field [0001] The invention relates to a movable tooth transmission device, in particular to a sprocket shock wave push rod movable tooth secondary speed reducer. [0002] technical background [0003] With the rapid development of industrial automation, numerical control machining, industrial robots and other fields and the improvement of modernization level, scientific researchers have continuously researched and developed various new transmission mechanisms with exquisite ideas, novel structures and unique performances on the basis of traditional mechanisms. , some institutions have been widely used, and some institutions have good application prospects. Among them, the movable tooth transmission mechanism is a new type of transmission mechanism evolved from a planetary gear transmission mechanism with a small tooth difference. It uses a set of intermediate movable parts, namely movable teeth, to transmit the motion and power between two coaxial axes, breaking thr...
