摘要
Based on the study of planetary differential roller screw, a planetary differential micro-displacement mechanism is designed for tool compensation. Axial stiffness is an important factor of over-all properties of planetary roller screw. The structure of planetary differential roller screw is similar to planetary roller screw. The axial stiffness was analyzed with Hertz contact theory and confirmed with the ANSYS. Finally, the theoretical values and simulation values were compared to verify the simplified model, and the error was analyzed. The results show that the relative error between simulation values and theoretical values are less than 5%. Therefore, the simplified model of the finite element is reasonable.
