| Abstract: | By considering the compressibility of lubricant and the transient effect of variable load, sliding Velocities and curvature varying with time and coordinate, the transient elasto-hydrodynamic lubrication analysis on spur involute gears is given. A parametric study is conducted to in-verstigate the effects of geometry factors (including gear ratio, gear teeth module and central distance) on the lubrication behavior of a gear transmission. The distribution of the central film thickness, central pressure and coefficients of friction along the line of action is obtained. |
