Globoidal Indexing Cam Mechanism Parameters Optimization Design And Simulation

Globoidal indexing cam mechanism is a precise transmission mechanism, because of its good performance, high speed high driving accuracy, positioning and reliable, the structure compact, carrying capacity and other significant advantages, is widely used in a variety of automatic machine and automatic production line. However, relative to the United States, Japan and other developed countries, China’s Globoidal indexing cam mechanism to carry out the research late, some of the key theoretical analysis is still under discussion, so the indexing cam mechanism further study on China’s mechanical automation technology has important practical significance.The paper researched on the Globoidal indexing cam mechanism by applying the theory of engagement in space and the method of rotary coordinate transformation, presented the equations of various types of parameters of the cam profiles,and analyzed the meshing characteristic.The paper focused on the parameters optimization design and simulation for Globoidal indexing cam mechanisms and established the parameters design system based on Visual C++Object-oriented method and Pro/Engineer secondary development, which can guide user to complete the data input with the friendly interface.It made synthesis of the mechanism and generation of the cam profile automatic.Then the assembly model was built under the circumstance of Pro/Engineer directly.And meanwhile the movement of the mechanism was simulated by using the Pro/Mechanism module of Pro/Engineer.The study of motion interference and properties base on the simulation under the circumstance of Pro/Engineer were made so that we can check whether the mechanism mesh properly or not.We can return to modify in time.
