By using the SolidWorks,the entity model of general level two spur gear and the revolution of secondary cylindrical gear deceleration institution is established,and the model is imported into ADAMS to establish the kinematics simulation analysis,the adding method of constraints,speed,contact force and load is given,the gear meshing force and frequency of contact image are got.Compared with the secondary gear reduction mechanism of general condition of two kinds of state of motion,the simulation results show that,the theoretical value and the simulation value has a little error,a certain theoretical and technical support for the revolution speed and speed of gear transmission optimization design and strength checking of gear and shaft is provided.
