【Abstract】 On the basis of analyses of traditional formulas for the calculation of velocity ratios in mechanisms having multiple structural components, the concept of transmission units and nodes were put forward, applying the finite element method as a reference. Multi-membered transmission units are reduced to two types of transmission units. Universal formula in the calculation of transmission velocity ratio of mechanisms having multiple structural components using the unit method was obtained. The paper developed the methods and steps to calculate the transmission velocity ratio of the mechanism using the unit method, and gave examples of calculation.更多还原
