摘要:
A lubricating oil composition for high-speed gears, particularly those having a peripheral speed of at least 10 m/sec, prepared by compounding a lube base oil having a percentage CA of 5 or less and desirably a nitrogen content of 50 ppm or less and a sulfur content of 50 ppm or less with additives based on, respectively, sulfur, phosphorus and nitrogen in such amounts that the element ratio, 100 N/(S+P), in the composition ranges from 4 to 10 by weight. The composition serves to develop satisfactory hypoid gear performance, is reduced in sludge formation, and can lengthen the service life of oil seal used in the high-speed and high-temperature rotating parts.
摘要(中):
一种用于高速齿轮的润滑油组合物,特别是具有至少10m /秒的圆周速度的润滑油组合物,其通过将具有5或更低的CA值,期望的氮含量为50ppm以下的润滑油基础油和 硫含量为50ppm以下,添加剂分别以硫,磷和氮为基准,使得组合物中的元素比例为100N /(S + P)为4〜10。 该组合物用于发展令人满意的准双曲面齿轮性能,减少了污泥形成,并且可以延长高速和高温旋转部件中使用的油封的使用寿命。
