摘要

During the operation of harmonic drive (HD), the parameters of the flexspline (FS) significantly influence the transmission performance of the HD. Furthermore, discrepancies between the actual deformation and theoretical deformation of the FS affect the transmission performance, as the tooth profile of the circular spline (CS) is calculated based on the FS's theoretical deformation. This study employs the envelope meshing theory to investigate the composite cycloid tooth profile, conducting a comparative analysis of how different parameters affect the conjugate region and conjugate tooth profile. The research also examines the error between the FS's actual and theoretical deformations, along with its underlying causes. Subsequently, the FS tooth profile is designed, and the deformed tooth profile is obtained through simulation, which is then used to calculate the corresponding CS tooth profile. The results demonstrate that appropriate selection of FS tooth profile parameters can effectively enhance the transmission performance of HD. The designed HD exhibits no tooth interference during operation, with 66.25% of the FS tooth profile maintaining continuous meshing with the CS tooth profile.
