In this paper, the lubrication condition of tractor transmission gear tooth surface is calculated by using the theory of fluid flow. The distribution curve of oil film thickness, contact pressure and friction coefficient along the tooth surface is made. The weak points of the tooth surface are analyzed. The direction and measures to improve the carrying capacity of the tooth surface are proposed.
