洪湖市经销点壳牌s2m液压油-极压齿轮油

　　齿轮油应具有良好的抗磨、耐负荷性能和合适的粘度。此外，还应具有良好的热氧化安定性、抗泡性、水分离性能和防锈性能。由于齿轮负荷一般都在490兆帕(MPa)以上，而双曲线齿面负荷更高达2942MPa，齿轮油的用量约占润滑油总量的6%~8%。齿轮油是性能优异的润滑油。

　　齿轮油以石油润滑油基础油或合成润滑油为主，加入极压抗磨剂和油性剂调制而成的一种重要的润滑油。用于各种齿轮传动装置，以防止齿面磨损、擦伤、烧结等，延长其使用寿命，提高传递功率效率。而双曲线齿面负荷更高达2942MPa，为防止油膜破裂造成齿面磨损和擦伤，在齿轮油中常加入极压抗磨剂，普遍采用硫- 磷或硫-磷-氮型添加剂。Gear oil should have good wear resistance, load resistance and appropriate viscosity. In addition, it should also have good thermal oxidation stability, anti-foaming, water separation and anti-rust performance. Because the gear load is generally over 490 MPa, and the hyperbolic gear load is even higher than 2942 MPa, the amount of gear oil is about 6% ~ 8% of the total amount of lubricating oil. Gear Oil is an excellent lubricant. Gear oil is an important lubricating oil made from petroleum-based base oil or Synthetic oil oil mixed with extreme pressure anti-wear agent and oiliness agent. Used in all kinds of gear transmission devices to prevent tooth surface wear, abrasion, sintering, etc. , extend its service life, improve the efficiency of power transmission. The load of hyperbolic tooth surface is 2942MPa. In order to prevent the wear and abrasion of tooth surface caused by oil film rupture, extreme pressure antiwear agent is often added to gear oil, and sulfur-phosphorus or sulfur-phosphorus-nitrogen type additives are widely used.
