The viscosity is large, the lubrication oil film formed is thicker, and the anti-load ability is relatively large. 2, enough extreme pressure wear resistance Extreme abrasion resistance is the most important property and main feature of gear oil. It is based on the performance of preventing tooth wear, abrasions, and cementation in the movement. The wear resistance and load resistance performance are generally above 490 MPa due to gear load, while the hyperbolic tooth surface load is as high as 2942 MPa. In order to prevent tooth surface wear and abrasion caused by oil film rupture, extremely pressure abrasives are generally added to gear oil. Sulpho-chlorine, thio-phosphorus-chlorine, thio-chloro-zinc, thio-lead and thio-phospho-lead additives were commonly used. Sulfur-phosphorus or sulfur-phosphorous-nitrogen additives are commonly used.
