| Abstract: | Based on the elastohydrodynamic lubrication theory of finite rollers,the effects of the time dependence characteristics of gear transmission on its elastohydrodynamic lubrication states were studied.The influences of dynamic viscosity of oils,entraining speed,and curvature radius on lubricant film thickness were analyzed.And the lubrication mechanism was discussed and explained.The relationships between lubrication factors and film thickness were obtained.Furthermore,some methods that can be used to improve the lubrication states of gear transmission were presented. |
