Simulation and Calculation: Improve Work Life of Bearing on Driving Gear of Main Reducer

摘要

The driving gear and driven gear in car rear axle have function of transmitting power. As important part of supporting driving gear, work life and situation of bearing have influence on power transmission. This paper improves system stiffness of gear and bearing, improves force situation of bearing by researching span between two bearings on driving gear. Work situation of main reducer can be improved through extending bearing life. The vibration and noise are reduced. Car market competition is improved.
