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.
