As we all know, the gear is one of the important lubrication points of the reducer. It usually works in the special environment of high temperature and high speed. In order to meet the lubrication and noise of the reducer gear under the conditions of high temperature and high speed, high temperature gear grease made of synthetic oil must be selected. What is the role of gear grease?
1. Improve the fatigue resistance of the tooth surface
Tooth surface contact stress is the main factor that affects tooth surface fatigue. It has a stable and sufficient oil film strength. Its lubrication state directly affects the tooth surface contact stress and improves the tooth surface fatigue resistance.
2. Reduce the vibration and noise of gear transmission
Since there are many reasons for gear vibration and noise, the viscosity of gear grease, which is very important for lubrication, can reduce gear vibration, shock, and noise. However, because of the different effects of lubrication and grease on gear vibration and noise, So choose the right gear grease.
3. Reduce tooth wear
Gear grease forms a certain strength of lubricating elastic oil film between the meshing surfaces of the gears, separating the meshing tooth surfaces, and the extreme pressure additives in the gear grease chemically react with the metal surface to produce a lubricating film, so it can cope with the boundary conditions that occur at any time , To achieve the purpose of maintaining the separation between gears and eliminating wear.
4. Avoid tooth surface bonding damage
Bonding is a general form of poor gear transmission. That is, on the meshing tooth surface, when the load and speed exceed the load capacity of the lubricating film, the lubricating film ruptures, the material of the meshing tooth surface directly contacts and rubs, causing wear, the temperature of the tooth surface rises sharply, and the two meshing tooth surfaces adhere to each other. , Form bonding damage. Gear grease has a certain degree of cohesiveness, load capacity and extreme pressure to ensure the separation of tooth surfaces and avoid bonding damage.
