The Three-Dimensional Modeling Method of the Deformed Flexspline with Involute Tooth Profiles

Abstract:

This paper is focused on the micro harmonic drive with a planet type wave generator in which flexspline consists of internal and external gear rings. The mathematical relationship between the coordinates of the points on the tooth profile of the deformed flexspline and that of the undeformed flexspline is derived by carrying on the coordinates transformation. According to this mathematical relationship, the coordinates of the points on the both sides of the tooth profile of every gear tooth of the one forth of the internal and external gear rings of the deformed flexspline are solved with the use of the mathematical software, then the coordinates are imported into the software Pro/E, and connect in a correct order with spline curves, the two curves have been mirrored and extended to finish the 3D modeling of the deformed flespline. At last, the FEM analysis of the deformed flexspline has been carried out.
