Thanks to recent advances in electric actuators, the power mass density of servo motors has greatly increased. However, high power is only possible at the range of high speed where the output torque is relatively low. A harmonic reducer with a high reduction ratio is usually adopted to increase...
The differential motion equations of each subsystem are derived and assembled to formulate a governing equation of the overall transmission system. Based on the established dynamic model, a modal analysis is carried out to reveal the modal characteristics of the star-wheel reducer. The results showed...
Based on the proposed model,the nonlinear differential equations of motion are derived and solved iteratively by the Runge-Kutta method. An NGW planetarygear reducer with three planets is taken as an example to analyze the effects of nonlinear factors. The results indicate that thebacklashes induce...
