There are many different ways to lubricate the inner and outer rings of the bearings, each of which has its own specific application scenarios and advantages. The following are some common lubrication methods for the inner and outer rings of the bearings:
Grease lubrication:
This is one of the most commonly used lubrication methods. By applying an appropriate amount of lubricating grease between the inner and outer rings of the bearings, friction and wear can be effectively reduced, while protecting the bearings from corrosion. Grease lubrication has the advantages of long lubrication cycles and simple maintenance, and is particularly suitable for medium and low speeds, medium and low temperatures, and occasions where it is not convenient to supply oil frequently.
Oil bath (oil immersion) lubrication:
Part or all of the bearing is immersed in lubricating oil, and the oil is brought into the other parts of the bearing for lubrication through the rotation of the bearing. This method is fully lubricated, but the oil supply is not easy to adjust, and if there is no filtering device in the oil tank, it is easy to bring impurities into the bearing and cause damage. Oil bath lubrication is generally suitable for low-speed or medium-speed bearings.
Oil cup drip lubrication:
Lubricate the bearing by dripping oil through the oil-saving port in the oil cup. This method has a simple structure, is easy to use, and saves oil. The oil supply can be adjusted through the oil saving port. However, it should be noted that there are certain requirements for the viscosity of the lubricating oil, and lubricating oil with too high viscosity cannot be used. Oil cup dripping lubrication is suitable for low speed, light load and low working temperature occasions.
Splash lubrication:
The oil is splashed through other running parts and brought into the bearing for lubrication. This method is suitable for bearings with higher speeds, but the oil supply is not easy to adjust, and the lubricating oil level cannot be too high, otherwise it is easy to cause stirring loss and temperature rise, and impurities in the oil tank may be brought into the bearing.
Circulating oil lubrication:
The lubricating oil is sucked out of the oil tank by the oil pump and transported to the part of the bearing that needs lubrication, and then returned to the oil tank from the oil return port, and reused after filtration. Circulating oil lubrication is a relatively ideal lubrication method with the largest and most stable oil supply. It is suitable for high-speed, heavy-loaded and important sliding bearings.
Oil mist lubrication and oil-gas lubrication:
Oil mist lubrication is to atomize the lubricating oil into tiny oil mist particles and then transport them to the bearing part for lubrication. It is suitable for high-speed occasions. Oil-gas lubrication is to mix a small amount of lubricating oil with a certain pressure of gas and supply it to the bearing, which is also suitable for high-speed applications. Both methods have the advantages of saving oil, small temperature rise and less impurities, but the cost of lubrication device is relatively high.
In summary, when choosing the lubrication method of Processing Of Bearing Inner And Outer Rings, it is necessary to comprehensively consider factors such as specific working conditions, speed, load and environmental requirements.
