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 maximizing the service life of SKF bearings, which is the highest performance of mechanical equipment. Performance status
1. Oil lubrication:
Viscosity is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of oil film formed between friction surfaces. The viscosity of lubricating oil at SKF bearing working temperature is generally 12-15cst. 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.
b. drip lubrication
Drip lubrication is suitable for bearing parts that need to supply lubricating oil quantitatively. The amount of dripping is generally one drop per 3-8 seconds. Excessive oil quantity will cause the bearing temperature to increase.
c. Circulating oil lubrication
The filtered oil is delivered to the bearing components by an oil pump, filtered through the lubricating oil after the bearings, and then cooled and used. Since the circulating oil can take a certain amount of heat to cool the bearing, this method is suitable for bearing parts with higher rotational speed.
d. Spray lubrication
The dry compressed air is mixed with the lubricating oil through a sprayer to form an oil mist. In the jet bearing, the air flow can effectively cool the bearing and prevent the intrusion of impurities. This method is suitable for the lubrication of high speed, high temperature bearing components.
