Elastohydrodynamic Lubrication Analysis of Elliptical Contacts with Rolling and Spinning
Tae-Jo Park , Hee-Jang Rhee and Gyeong-Mo Yeo
ABSTRACT
A theoretical study of elastohydrodynamic lubrication of elliptical contacts with both rolling and spinning has been carried out. A finite difference method and the Newton-Raphson method are applied to solve the problem systematically. The velocity vectors resulting from combined rolling and spinning motion of the mating surfaces lead to asymmetric pressure distributions and film shapes. Film contours and variations of the minimum and central film thicknesses are compared with various spin-roll ratios. At high spin-roll ratios the minimum film thickness is considerably reduced, whereas the central film thickness decreases less dramatically. Therefore present numerical scheme can be used in the analysis of general elliptical contact EHL problems.
