How to lubricate the gear reducer. Regarding the lubrication of the reducer, it is also very important for the maintenance of the reducer. Open type and semi-open type gear reducer transmission, or low-speed closed gear transmission, are usually replenished and lubricated by humans. The lubricant used is lubricating oil or grease. Reducer lubrication also has its own conditions, and the conditions for different reducer lubrication are also different. Let's take a look at how Shanghai Jinchuan reducer performs lubrication of gear reducer.

When the peripheral speed of the gear of the reducer is more than 12m / S, oil injection lubrication should be adopted, that is, the oil is supplied by the oil pump or the central oil supply station at a fixed pressure, and the lubricant is sprayed onto the gear table by the nozzle. When v≤25m / s, the nozzle can be located on the side where the gear teeth engage or whistle; when v> 25m / s, the nozzle should be on the side where the gear teeth whistle, in order to use the lubricant to cool the newly meshed Gear teeth also lubricate the gear teeth.

General closed gear reducer transmission, its lubrication method depends on the peripheral speed of the gear. When the peripheral speed V of the gear is less than 12m / s, the gear teeth of the large gear are often immersed in the oil field for oil immersion lubrication. In this way, when the gear is transmitting, it brings the lubricant to the meshed tooth surface, and at the same time, it also throws the oil on the box wall to dissipate heat. The depth of the gear immersed in the oil depends on the circumferential speed of the gear. For cylindrical gears, it is usually not more than one tooth height, but it should not be less than 10mm. half. In multi-stage gear transmission, the oil can be brought to the tooth surface of the gear that is not immersed in the oil by the oil tanker.

The amount of oil in the oil pool depends on the amount of power transmitted by the gear. For a single-stage transmission, the oil demand is about 0.35 ~ 0.7Lo for each Ikw of power transmitted. For a multi-stage transmission, the oil demand is multiplied by the number of stages.
