According to transmission principle and structure characteristics of two-tooth dltterence swing movable teeth transmission, three-dimensional solid modeling and virtual assembly of two-tooth difference swing movable teeth transmission system were carried out in Pro/E environment. Kinematics simulation of transmission system was performed. With help of virtual assembly and kinematics simulation of transmission system, interference checking was made through with. The simulation results were analyzed and show that structure design of two-tooth difference swing movable teeth transmission is feasible and rational. By using study method put forward , design defects can be found earlier, design cycle can be shorten and cost of product development can be reduced. The method can be applied to virtual prototype design of other mechanisms also.
