【Abstract】 The 2K-V are planetary gears train with cycloid gears used in industrial robots and machines requiring good vibration characteristics. The natural frequency of the reducer should be as high as possible in order to apply these planetary gears in various industrial fields. In this paper, the dynamic model of 2K-V reducer is formulated. Moreover, the effects of the addendum modification coefficient and coefficient of tooth shape on the meshing stiffness were analyzed. Meanwhile, using the model, the effects of pin-diameter coefficient and stiff-nesses on the vibration characteristics were predicted.更多还原
