EFFECT OF VISCOUS SHEAR HEATING ON BOTH FILM THICKNESS AND ROLLING TRACTION IN AN EHL LINE CONTACT - 2. STARVED CONDITIONS.

In this part, analysis is extended to consider the calculation of starved rolling traction and film thickness, including viscous shear heating of the lubricant in the inlet region. An approximate equation has been developed, which predicts both the isothermal and non isothermal starved film thickness for all conditions of inlet boundary distance, rolling speed, load, geometry, material constants and lubricant properties. The results show that both rolling traction adn film thickness are significantly reduced from the starved isothermal case. For the starved isothermal case, the theoretical analysis for the film thickness agrees closely with experimental data and published empirical formula by wymer and Cameron, (1974) and the theoretical work of Wolveridge, et al. (1971).
