Abstract

Harmonic drive show an extraordinary transmission characteristic with high with high efficiency and attract considerable attention. In this article, a double-arc tooth profile harmonic drive was designed. An explicit finite element analysis (FEA) about deformation, torsion, stress and contact force under different loads was put forward and compared with theoretical analysis and experimental results. The effect of different load to redistribution of stress on the flexspline (FS) and the change of the contact force distribution are also researched. The result shows that the hysteresis behavior in the torsion of FS cup due to energy storage and release lead to the change of distribution. Besides, the hysteresis behavior in FEA is also identified by the agreement with experimental results. Furthermore, the torsion of FS cup of double-arc tooth profile HD independent on kinematic errors is elaborated based on FEM. The article shows a meaningful attempt for the double-arc tooth profile harmonic drive improvement.
