机油和齿轮油虽然都属于涧滑油,但由于各自的理化性能和添加剂种类不同,两者不但不能混合使用,而且也不能互相替换使用,更不能用废机油代替齿轮油。我们发现有些驾驶员,把从油底壳放出来的废机油倒入变速箱作润滑齿轮用,这是极其有害的:1.废机油比齿轮油粘度小,在齿轮接触而上不能形成油膜,当两齿而相互滑动时,就会在较软的齿而上撕下部分金属,“焊”在另一较硬的齿面上,形成胶合沟纹,损坏齿面。同时,因废机油过稀,各传动轴轴承易发生干摩擦,加速磨损。2.废机油含有较多的金属磨屑和杂质,倒入变速箱后,就会随机油飞溅到齿轮啮合表面及变速箱支承轴轴承上,加剧了齿轮和轴承
Although oil and gear oil belong to the oil, but because of their different physical and chemical properties and types of additives, both not only can not be mixed, but also can not replace each other to use, but can not use waste oil instead of gear oil. We found that some drivers, the waste oil discharged from the oil pan into the gearbox for lubrication with gear, which is extremely harmful: 1. Waste oil viscosity than the gear oil, the gear can not be formed in contact with the oil film, When two teeth slide against each other, part of the metal is removed from the softer teeth and the “weld” on another harder tooth surface forms a glued groove that damages the tooth surface. At the same time, due to waste oil is too thin, the shaft bearings prone to dry friction, accelerated wear and tear. 2 waste oil contains more metal debris and impurities, into the gearbox, it will be random oil splashed gear meshing surface and gearbox bearing shaft bearings, exacerbating the gear and bearings
