Abstract
In this study, the geometric analysis of an eccentric transmission with intermediate rolling elements is performed. The outer surface of the disk is mounted on the drive shaft. The rolling elements interact with the outer surface of the disk, the inner cam profile of the central wheel, and the surfaces of the radial grooves of the driven shaft with eccentricity. The transmission has low material consumption. The transmission provides transmission ratios in the range of 6...60 in a single stage. The design does not have an additional mechanism for transmitting rotation from the satellite to the driven shaft. The motion trajectories of the centers of mass of rolling elements are obtained. The trajectory equations are the equations of the center curves of the cam profile of the center wheel. An algorithm for calculating the main geometric parameters of transmissions is developed. Experimental samples of reducers based on eccentric transmission are created.
