    Abstract
  • The transmission performance was analyzed , based on the device structure and transmission principle of the discrete teeth harmonic drive. The optimization design model for the rigid spline was established based on the relationship between the character of rigid spline and the transmission performance. And that the pressure angle of rigid spline tooth profile minimum as the optimization design goal was confirmed to improve the transmission efficiency; the optimizing design variables were confirmed according to the tooth profile curve equation of the rigid spline to achieve the parameters of the rigid spline optimized, and the constraint conditions were confirmed on the basis of the transmission properties to ensure normal transmission. The example shows the method above can effectively reduce the pressure angle of rigid spline tooth profile, which improves the transmission property.
