摘要：
An approach of loaded tooth contact analysis of muti-gear for planetary transmission was proposed to simulate gears performances. The relative tooth clearances of external (internal) gear pair were calculated based on tooth contact analysis(TCA) considering accurate topography of tooth surfaces with alignment errors. The normal flexibility matrix caused by unit normal force of tooth surface point were obtained by computing flexibility coefficients based on finite element, and based on which normal flexibility coefficient of points on tooth contact lines for external (internal) gear pairs were calculated by interpolating and summing the the flexibility coefficient from sun and planet gears (planet gears and ring gear). With geometric analysis and mechanical analysis of gears, the tooth contact problem for gear pairs under load were represented to mechanical equilibrium problem of finite contact points. Besides, deformation, meshing stiffness, loads distribution and load sharing coefficient were obtained by solving the non-linear equations applied mathematical programming. Simulation results from transmission errors and load distribution under loads show validity of the method, which contribute to design of modified tooth surfaces and dynamic analysis for high-performance planetary gears. © 2019 Automation of Electric Power Systems Press.
