汽车齿轮油的作用有哪些
What are the functions of automobile gear oil
车辆齿轮油(vehicle gear oil)通常把用于汽车手动变速器、后桥主减速器及差速器的润滑油称为齿轮油。
Vehicle gear oil usually refers to the lubricating oil used for automobile manual transmission, rear axle final drive and differential as gear oil.
齿轮油的重要作用就是在齿轮的齿齿接触面上形成油膜或牢固的吸附膜和化学反应膜，以保证正常的润滑并防止齿面间胶合。
The important function of gear oil is to form oil film or firm adsorption film and chemical reaction film on the contact surface of gear teeth, so as to ensure normal lubrication and prevent tooth surface from gluing.
随着咬合方式不同，齿轮上润滑油膜的形式有显著差异。正、斜和螺旋伞等齿轮齿面上容易形成润滑油膜，双曲线齿轮体积较小，传递的动力大，齿面相对滑动速度大，齿面上难以形成润滑油膜，是最难润滑的摩擦之一。
The form of lubricating oil film on gears is significantly different with different occlusal modes. It is easy to form lubricating oil film on the tooth surface of spur gear, bevel gear and spiral bevel gear. Hyperbolic gear is one of the most difficult to lubricate because of its small volume, large power transmission and high relative sliding speed.
