羅定市殼牌shell液壓油-G220齒輪油銷售處
齒輪油以石油潤滑油基礎油或合成潤滑油為主，加入極壓抗磨劑和油性劑調制而成的一種重要的潤滑油。用于各種齒輪傳動裝置，以防止齒面磨損、擦傷、燒結等，延長其使用壽命，提高傳遞功率效率。齒輪油應具有良好的抗磨、耐負荷性能和合適的粘度。此外，還應具有良好的熱氧化安定性、抗泡性、水分離性能和防銹性能。
由于齒輪負荷一般都在490兆帕(MPa)以上，而雙曲線齒面負荷更高達2942MPa，為防止油膜破裂造成齒面磨損和擦傷，在齒輪油中常加入極壓抗磨劑，普遍采用硫- 磷或硫-磷-氮型添加劑。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. 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 performance and anti-rust performance. Because the gear load is generally over 490 MPa, and the hyperbolic gear load is even higher than 2942 MPA, in order to prevent the oil film from breaking and causing wear and abrasion, extreme pressure antiwear agent is often added to the gear oil, s-P or s-p-n type additives are widely used.
