The orthogonal anal⁃ysis method is used to analyze the range of the factors affecting the gear oil loss. The main factors affecting thegear churning power loss are speed，gear oil kinematic viscosity，oil depth，number of teeth，tooth width，gear he⁃lix angle and pressure angle，and the specific influence sensitivity of each factor is studied. Through Particle⁃Works and Romax software，a transmission efficiency analysis model of the reducer is constructed and a trans⁃mission efficiency experiment is conducted. Through the comparison and analysis of the experiment and thetransmission efficiency simulation，the feasibility and accuracy of the simulation model are verified. A new meanto study the transmiss...
