Abstract

The normal section tooth profile of the hob basic rack is used creatively as the basic rack of the harmonic gear drive with double-circular-arc. Based on the clear selection methods of the basic rack tooth profile's main parameters, the optimization method and process of the basic rack tooth profile is proposed, and the validity and feasibility of the design is verified with example. By simulation, the composition of the circular spline (CS) tooth profile is determined, whose addendum and dedendum tooth profiles are formed by the flexible spline (FS) addendum tooth profile's enveloping, whose middle tooth profile is formed by the FS middle involute tooth profile's enveloping. It's concluded that the harmonic gear drive with this basic rack has fully realized the whole tooth conjugate contact, which is the most effective way to improve the comprehensive performance of the harmonic gear drive.
