Due to the change of the radial dimension of the shock absorber cam profile, it generates radial thrust, which pushes the swinging movable tooth to swing around the uniform pin on the movable rack, and at the same time, due to the high pair between the swinging movable tooth and the center wheel The constraint of A forces the oscillating movable tooth to roll along the tooth profile of the center wheel, and pushes the movable tooth frame to rotate at an equal angular velocity by the uniform pin, so that the oscillating movable gear reducer completes the rotational speed changing motion. The N-type small-tooth difference planetary transmission such as the cycloidal planetary transmission of the mechanism has been successfully removed, which is determined by the transmission principle. The low speed of the planetary gear needs to be output from the output shaft through the W output mechanism. For example, the W mechanism of a cycloidal pinion planetary transmission consists of an equal split hole on the cycloidal wheel, a distribution shaft and a pin bushing mounted on the output shaft. The equal division accuracy of the equal-divided holes and other distribution axes has a great influence on the motion accuracy, transmission stability, noise and load carrying capacity of the reducer. Since the oscillating movable tooth reducer adopts the "swinging movable tooth technology", the oscillating movable tooth meshing copy body has the performance of the W mechanism, and the W mechanism is successfully removed, which fundamentally eliminates the manufacturing precision of the W mechanism and fails to meet the requirements. The above drawbacks are brought about.
Solved the problem of the life of the transfer bearing. The pin-pin type constant-speed output mechanism of the cycloidal pin reducer consists of a uniform pin on the output shaft and a uniform pin hole on the cycloidal wheel. The diameter of the pin hole is twice the diameter of the pin shaft, occupying most of the position of the cycloidal wheel, which limits the size of the shock absorber arm bearing. Therefore, the arm bearing becomes the weak link of the cycloidal pinwheel reducer. Its life determines the life of the cycloid reducer. The oscillating movable tooth meshing pair of the oscillating movable tooth reducer is used for the speed change, and also has the function of transmitting the rotational speed between the moving shaft and the fixed shaft, so that the hole pin type constant velocity output mechanism of the cycloidal pinwheel reducer can be removed. It provides enough space for the arm bearing to solve the key problem that the slewing pin wheel reducer's slewing bearing is limited by the radial size and the strength is insufficient. Therefore, under the condition of transmitting the same power, the oscillating movable gear reducer has smaller radial size, lighter weight and long service life than the cycloidal pin reducer.
