Operating temperatures of oil-lubricated medium-speed gears : numerical models and experimental results.

Long, H. and Lord, A. A. and Gethin, D. T. and Roylance, B. J. (2003) 'Operating temperatures of oil-lubricated medium-speed gears : numerical models and experimental results.', Proceedings of the I MECH E part G : journal of aerospace engineering., 217 (2). pp. 87-106.


This paper investigates the effects of gear geometry, rotational speed and applied load, as well as lubrication conditions on surface temperature of high-speed gear teeth. The analytical approach and procedure for estimating frictional heat flux and heat transfer coefficients of gear teeth in high-speed operational conditions was developed and accounts for the effect of oil mist as a cooling medium. Numerical simulations of tooth temperature based on finite element analysis were established to investigate temperature distributions and variations over a range of applied load and rotational speed, which compared well with experimental measurements. A sensitivity analysis of surface temperature to gear configuration, frictional heat flux, heat transfer coefficients, and oil and ambient temperatures was conducted and the major parameters influencing surface temperature were evaluated.

Item Type:Article
Keywords:Tooth temperature, Frictional heating, Convection heat transfer, Finite element temperature analysis, Spur gear transmission.
