There are several ways to lubricate imported bearings, and each type of bearing and all types of bearings are also different when using lubrication, which is more conducive to maximize the service life of imported bearings, which is the highest performance of mechanical equipment. Performance status
1, solid lubrication
Under some special conditions, a small amount of solid lubricant is added to the grease. For example, adding 3~5% of molybdenum disulfide No. 1 can reduce wear and improve the resistance to pressure and heat. For high temperature, elegance, high vacuum and corrosion resistance. Special conditions such as anti-radiation and extremely low temperature, the solid lubricant can be added into engineering plastics or powder metallurgy materials to make bearing parts with self-lubricating properties, such as bonding the solid lubricant to the raceway with an adhesive. A lubricating film is formed on the cage and the rolling elements, which has a certain effect on reducing friction and wear.
2, oil lubrication:
Viscosity is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of the lubricating oil and the thickness of the oil film formed between the friction surfaces. The viscosity of the lubricating oil at the working temperature of the bearing is generally 12-15 cst. The higher the speed, the lower the viscosity, and the heavier the load, the higher the viscosity. Commonly used lubricating oils include mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil, and the like.
Oil lubrication methods include:
a. Oil bath lubrication
Oil bath lubrication is the most common lubrication method. It is suitable for the lubrication of low and medium speed bearings. Part of the bearing is immersed in the groove. The lubricating oil is brought up by the rotating bearing parts and then flows back to the oil groove. The oil level should be slightly lower than the minimum. The center of the rolling element.
