汽车油封是汽车上使用广、数量多、易损耗配件,主要用于汽车各种回转轴上,如曲轴油封、气门油封、喷油泵油封、变速器油封、传动轴油封、差速器油封、半轴油封等。具有防漏密封、防尘、防水功能。 一、汽车各种回转部件对油封的性能要求: 1.良好的防漏性能 防漏是油封的重要技术性能。一般情况,固定密封只要材质符合要求,安装准妥,是可以达到“防漏要求”的。但是,对于运动部件,特别是回转轴类零件要做到不漏则不甚容易,而且漏油的原因复杂不易解决,所以一些国家对油封泄漏量作出
Automobile oil seal is widely used on the car, a large number, easy to wear parts, mainly for the automotive rotary shaft, such as crankshaft oil seal, valve seal, fuel injection pump seal, transmission seal, shaft seal, differential seal, Oil seal and so on. With leak-proof seal, dust-proof, waterproof function. First, the various components of the car on the oil seal performance requirements: 1. Good leak resistance leakproof seal is an important technical performance. In general, the fixed seal as long as the material meets the requirements, installation properly, is to achieve “leak-proof requirements.” However, for moving parts, especially rotary shaft parts are not easy to leak, and the reasons for the oil leakage is not easy to solve, so some countries on the oil seal leakage
