A Double Shock Roller Movable Tooth Reducer with Backlash Elimination Mechanism

Abstract

The invention discloses a double-shock-wave roller column movable tooth speed reducer with a gap eliminating mechanism. The double-shock-wave roller column movable tooth speed reducer mainly comprisesa first eccentric circle shock wave device, a second eccentric circle shock wave device, conical roller column movable teeth, a first center wheel, a second center wheel, a movable teeth frame, a shell, an input shaft and an output shaft. The two rows of conical roller column movable teeth are symmetrically arranged in opposite directions. The first eccentric circle shock wave device and the second eccentric circle shock wave device are arranged in opposite directions with a 180-degree phase difference. The conical roller movable teeth are adopted, so that the bearing capacity of the speed reducer can be improved, and gaps can be eliminated by adjusting the axial position. The input shaft is connected with the first eccentric circle shock wave device and the second eccentric circle shockwave device through a spline structure. Threads are machined at the two ends of the spline section to be connected with round nuts. Spring devices are arranged on the inner sides and outer sides of the first eccentric circle shock wave device and second eccentric circle shock wave device at the same time. The shock wave devices are pushed by elastic force to axially move to realize the function ofgap elimination. The bearing capability and the centering performance of the shock wave device and a shaft are improved by a spline. The elastic force of a spring is controlled through threaded connection.

Description

technical field [0001] The invention relates to a roller movable tooth reducer, in particular to a double-shock wave roller movable tooth reducer with an anti-backlash mechanism. Background technique [0002] Roller movable tooth transmission is the simplest structural form in movable tooth transmission, because of its simple structure and good transmission performance, it has attracted widespread attention. In the existing roller movable tooth transmission device, the movable tooth generally adopts cylindrical rollers, and steel balls are also used in some cases. After the device runs for a period of time, the movable tooth will wear out, the transmission device will have wear gaps, and the transmission noise will become larger. work has a greater impact. [0003] The patent application number is CN201310606488.8. A gapless power output device is installed between the body and the fixed wheel to generate a constant axial force to push the fixed wheel to move axially, and t...

AI Technical Summary

Problems solved by technology

However, there is no guiding device for the axial movement of the fixed wheel, which is prone to uneven force on the fixed wheel, deflection of the center line, affecting the transmission, and even causing jamming

The movable tooth is a hollow structure, which affects the rigidity of the movable tooth. The internal structure of the movable tooth is complex, which is prone to failure and affects the transmission.
