Abstract

Previous research revealed that gear tooth failure is close related with tooth surface and bulk temperature. In this paper, the bulk temperature of high-speed gear tooth is analyzed using finite element method. The analytical approach and procedure for estimating frictional heat flux and heat transfer coefficients of gear teeth in high-speed operational conditions is developed and accounts for the effects of pressurized oil jet cooling. The bulk temperature under oil jet and oil mist lubrication are compared and results show that oil jet lubrication is more effective in reducing gear bulk temperature than oil mist lubrication.
