Qingdao University of Science & Technology, Qingdao, Shandong, China
The purpose of this paper is to derive the simplified elastohydrodynamic (EHD) lubrication model of the double involute gear (DIG) and study the effect of the segmented tooth waist on the lubricating properties of DIG. Geometric analysis of the DIG gear was performed on the simplified EHD lubrication model based on the engagement theory, and then the line contact steady isothermal Reynolds’ equation was established. Numerical analysis of EHD lubrication of the new gear drive was conducted by using the multi-grid method.
