The importance of lubrication for imported bearings is mentioned in the article "Checking the faults and handling of imported bearings in operation". Now let's talk about the effects of lubrication on imported bearings. Whether the lubricant or lubrication method is correct or not will greatly affect the life of the imported bearings.
The impact of lubrication on the performance of imported bearings can be divided into the following aspects:
1. Firstly, lubricate the parts of the imported bearings to reduce the friction and wear of the imported bearings;
2. The rolling contact surface of the imported bearing often forms an appropriate oil film to prolong the fatigue life of the imported bearing;
3. The heat generated by friction or other reasons inside the imported bearing is removed by lubrication;
4, through the lubrication can achieve the effect of rust and dust on the imported bearings.
The two main lubrication methods for imported bearings are grease lubrication and oil lubrication.
Grease lubrication has a sealing method in which the sealed bearing is filled with grease in advance, and a filling and fat filling method in which the inside of the outer casing is filled with an appropriate amount of grease and replenished or replaced at intervals. In addition, for machines that require multiple bearings to be lubricated, a centralized grease supply method that connects the pipes to each lubrication location is also used. Grease lubrication can be used after filling the grease for a long time without replenishing, and the structure of the sealing device is relatively simple, so it is widely used. Oil lubrication is relatively simple. Regular lubrication can increase the service life of imported bearings.
