【Abstract】 The dynamics characteristics of transplanting mechanism with planetary spur gears were analyzed by using the method we derived. The method includes differential equations of rigid compound motion and stepwise solving solution of dynamics equations sets. Dynamics model of the mechanism was set up, and the relationships between rotary angle of planetary carrier and the force of several positions were obtained. The positions were chain, axle of central elliptical gear, axle of middle gears, axle of planetary gears, meshing point between central gear and middle gear, and meshing point between planetary gear and middle gear. What we mentioned above provided theoretical bases to optimize its dynamics parameters and analyze strength of the mechanism.更多还原
