Gear Surface Improvement Lubricant

The main purpose of gear lubrication is to reduce friction, improve efficiency, reduce wear and contact fatigue of interacting tooth surfaces, and improve durability. Since the 19th century, gear tribology has solved the problem of lubrication performance. Subsequently, many engineers and researchers have continuously improved gear lubrication methods and conditions, and established a basic fluid lubrication theory for two rotating cylinders in contact, which considers sliding effect.

Over the years, gear lubrication has been continuously improved, and the research results have formed practical rules.

In theory, just like micropitting, wear and scratch damage can be eliminated through effective lubrication. This is the formation of an oil film whose thickness exceeds the combined height of the tooth surface roughness in the contact area. As reported by the researchers, the experiment investigated the relationship between the severity of lubricant starvation and sliding speed during sliding.
