Parametric Modeling of a Cycloid Drive Relative to Input Shaft Angle

Abstract

Creating an equidistant of the shortened epitrochoid curve for a cycloid drive disc is a complex process. By automating this process using a parametric input curve drawing program, the geometry can be precisely defined. In this paper a cycloid drive model is created using such a program written for these purposes. The program input also creates other drive component curves and places them in their current positions relative to the input shaft rotation angle. The model generated from this geometry represents a valuable and time efficient initiate for further stress analyses of cycloid drive components. Automating this process also decreases the possibility of human error and allows for easily changeable input shaft angles.
