A harmonic gear drive is a compact mechanical device guaranteeing high mechanical advantage and speed reduction. The harmonic drive operates on the principle of flexible-body mechanics, from which we can obtain high torque transmission capability in a single stage. The harmonic drive mainly consists of a wave generator, a flexspline, and a circular spline. Among these components, the flexspline plays an important role in operating the flexible-body mechanics. It is a thin cup-shaped feature containing teeth profile, and usually manufactured in metal. The present study aims to develop a flexspline for a plastic harmonic drive so as to reduce the part weight as well as manufacturing cost. A structural finite element (FE) analysis is carried out in order to verify the structural safety of the plastic flexspline under given deformation conditions. A nonlinear FE analysis considering a deformable body contact is also performed to investigate the contact stress between the teeth of the flexspline and the circular spline.
