Abstract
A cycloid speed reducer assembly is disclosed for optimizing the component structure. The accommodation space required for the sealing element is integrated into the track ring to save the material costs and significantly reduce the overall volume. A spacer ring placed between the front and rear bearings is used to adjust the clearances of the front bearing and the rear bearing to facilitate the quantitative production and control the yield. Since the compact structure of the cycloid speed reducer assembly includes two output ends, it facilitates to arrange an encoder between the speed reducer and the motor for closed-loop feedback control, so as to improve the control accuracy of the system. With the hollow input shaft, dual encoder applications can be realized. When a flexible structure is added to the output end, the flexible structure can be connected to another encoder to further realize the application of the torque sensor.
