Transient Thermal Lubrication Analysis of Involute Gear

With the development of modern machine, the gear sets have to operate under high power high revolution; lubrication performance plays a vital role to the gear sets. In this study, lubrication analysis of spur gears under high speed is conducted based on the elliptical contact and unified Reynolds equation system model. The transient effect and thermal effect are taken into considered. The results show that the transient effect strongly influences the lubrication characteristics during the mesh cycle, while thermal effect enhances the transient effect.
