摘要：
This article studies the lubrication state of the arc tooth cylindrical gears during injection lubrication. The mathematical model of arc tooth cylindrical gears are established based on meshing principle. The lubrication characteristics of arc tooth cylindrical gears under different injection methods and conditions are analysed by using computational fluid dynamics (CFD) model. The variation law of oil volume fraction in the gear-meshing zone is obtained. Comparing the two oil jet methods in into mesh lubrication, when the ratio of the pitch line velocity to the injection velocity is less than 1.5 times, the best lubrication is gained through the concave surface injection method, when the ratio of the pitch line velocity to the injection velocity is more than 1.5 times, the best lubrication is gained through the convex surface injection method. It shows that the tooth shape has significant influence on lubrication when the lubricating oil is injected.
