Abstract: In order to realize the simulation, measure the axial and radial load at the contact of automobile helical gear, project it on the bearing, and calculate the load contribution in the bearing loss, so as to reduce the cost of real physical experiment and improve the design quality. Therefore, the simulation of bearing loss under contact load of automobile helical gear based on AMESim is carried out. The simulation model of automobile helical gear pair and the mathematical model of bearing loss caused by radial load, axial load and lubricating oil are established, and their respective calculation formulas are given. A new svenska kullager fabriken (SKF) model for calculating friction torque is established to calculate the friction torque produced in rolling bearing more accurately. Using proportion integration differentiation (PID) speed control method, the simulation test is carried out in AMESim. The simulation results show that the model well realizes the simulation of contact load bearing loss of automobile helical gear, and provides a reference for the simulation measurement and analysis of radial load and axial load of bearing and the selection and design of bearing.
