Purpose and method of rolling bearing lubrication Rolling bearing is also a kind of commonly used mechanical hardware products. It needs to be lubricated continuously during the use process to ensure its normal operation. What are the main purposes of rolling bearing lubrication treatment? What are the methods of lubrication treatment? Today Xiaobian is doing the following sorting for you, hoping to help more people have an understanding and understanding of these bearings!
The main purposes of rolling bearing lubrication are:
1. Reduce friction and wear: Prevent metal contact and reduce friction and wear in the contact parts of the ferrule, rolling element and retainer that make up the bearing.
2, prolong the fatigue life: the rolling fatigue life of the bearing, in the rotation, the rolling contact surface is well lubricated, it is prolonged. Conversely, if the oil viscosity is low and the thickness of the lubricating oil film is not good, it is shortened.
3. Exhaust friction heat and cooling: The circulating oil supply method can use oil to discharge heat generated by friction or heat from outside to cool. Prevent the bearing from overheating and prevent the lubricant from aging itself.
4. Others: It also has the effect of preventing foreign matter from intruding into the bearing or preventing rust and corrosion.
The main method of rolling bearing lubrication:
At present, the lubrication method of the bearing mainly has two different ways of grease lubrication and oil lubrication; in order to make the bearing function well, first, it is necessary to select a lubrication method suitable for the use condition and purpose of use. Lubricity of oil lubrication predominates if only lubrication is considered. However, grease lubrication has the advantage of simplifying the structure around the bearing, comparing the advantages and disadvantages of grease lubrication and oil lubrication.
