Abstract:: This article proposes a complete numerical method that calculates the problem of non -stable elastic fluid power lubrication, and applies this method to the elasticity calculation of the straight gear transmission. It is included in the changes, curvature radius changes, speed changes, and surface telescopic effects of various points on the meshing line. This article has successfully obtained the distribution of non -stable film thickness edges. The results show that there are many differences between non -stable computing results and steady -state calculation results. The thickness of the non -stable calculation of the thickness of the oil membrane has the characteristics of mutation with mutations with the oil membrane. Finally, this article discusses the effects of the surface telescopic effect on the calculation of non -stabilizing stream.
