Abstract
There are three main rolling nodes in the cycloidal gear reducer: the gear, output mechanism and central bearing. To transfer the drive from the active side to the output side of the gear, an output mechanism is used, which is formed by bushings mounted on pins located in the output shaft. During the operation of the reducer, the bushings roll around the wheel holes with a cycloidal contour. Using the structure and geometry of the output mechanism, an analysis of the backlash distribution in it was conducted, taking into account the machining deviations of the elements and surfaces forming this mechanism. Then, the distribution of forces and contact pressures were determined. The results of the analysis suggest that the backlash distribution, forces and contact pressures largely depend on the tolerance of the radius of the bushings’ arrangement and the holes in the planet wheel. The results obtained allow for the optimal selection of machining deviations in terms of received contact pressures.
