Lubricating oil is needed in gear processing, and there will be friction in gear processing. Therefore, in order to reduce the damage, lubricating oil is needed to reduce the friction in the processing process. How to choose the lubricating oil for gear processing?

Gear lubrication is an intermittent lubrication process. When the gears mesh, a new oil film will be formed between the teeth to lubricate between the teeth. In principle, gear lubrication has three lubrication modes: hydrodynamic lubrication, elastic dynamic lubrication and boundary lubrication.

The working conditions of gear processing are complex, and the requirements for the performance and function of oil are also different. Most gears are in mixed lubrication state, which is mainly due to boundary lubrication at start-up, boundary lubrication at low speed and heavy load, and elastic fluid lubrication at high speed and low load. When the tooth surface contacts, more heat is generated, and the instantaneous contact temperature is sometimes very high.

Most of the bearing capacity of gear processing is transmitted by the oil pressure of the lubricating oil in the lubrication gap, and the rest is transmitted by the tooth surface contact. Therefore, the load calculation capacity of the lubricating oil can reach or approach the strength value of biomaterials. The working environment performance of gear transmission control device is limited by torque and speed. If the torque and speed exceed our time limit, it will lead to various forms of damage: wear, scratch, pitting and fracture.

When the gear is processed and operated, it will be exposed to some corrosive media, water and gas, resulting in serious corrosion and corrosion wear. Therefore, the oil that can be used should have the effect of anti-corrosion and anti rust treatment. The above is to introduce the selection of lubricating oil for gear processing.
