　　极压抗磨性是齿轮油最重要的性质、最主要的特点。

　　是赖以防止运动中齿面磨损、擦伤、胶合的性能。

　　抗磨、耐负荷性能 由于齿轮负荷一般都在490MPa以上，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，在齿轮油中一般都加入极压抗磨剂，以前常用硫-氯型、硫-磷-氯型、硫-氯-磷-锌型、硫-铅型和硫-磷-铅型添加剂。普遍采用硫-磷或硫-磷-氮型添加剂。

　　3、良好的抗乳化性

　　齿轮油遇水发生乳化变质会严重影响润滑油膜形成而引起擦伤、磨损。

　　4、良好的氧化安定性和热安定性

　　良好的热氧化安定性保证油品的使用寿命Extreme pressure and wear resistance are the most important properties and main characteristics of gear oil.

　　It is a performance that relies on preventing tooth wear, abrasion, and adhesion during movement.

　　Due to the fact that gear loads are generally above 490 MPa, and hyperbolic tooth surface loads can reach up to 2942 MPa, extreme pressure anti-wear agents are generally added to gear oil to prevent tooth surface wear and abrasion caused by oil film rupture. Previously, sulfur chlorine, sulfur phosphorus zinc, sulfur lead, and sulfur phosphorus lead additives were commonly used. Sulfur phosphorus or sulfur phosphorus nitrogen additives are commonly used
