The purpose and method of rolling bearing lubrication

Rolling bearing is also a kind of commonly used mechanical hardware products, its use in the process of constantly need to be lubricated, in order to ensure its normal work, so what are the main purposes of rolling bearing lubrication treatment?What are the methods of lubrication treatment?Today xiaobian for you to the following arrangement, I hope to help more people have a understanding of this kind of bearing and understanding it! The main purposes of rolling bearing lubrication are:1、Reduce friction and wear: in the form of bearing ring, rolling body and holder of mutual contact parts, prevent metal contact, reduce friction and wear2、Prolonging fatigue life: the rolling fatigue life of the bearing can be prolonged when the rolling contact surface is well lubricated during rotation.On the contrary, low oil viscosity, lubricating oil film thickness is not good, then shorten.3、Exhaust friction heat, cooling: oil circulation method can be produced by the friction of oil exhaust heat, or heat from the outside, cooling.Prevent the bearing from overheating and the lubricating oil from aging.4、Other: also have to prevent the invasion of foreign bodies inside the bearing, or prevent rust, corrosion effect.Main methods of rolling bearing lubrication:
At present, the lubrication methods of bearing mainly include grease lubrication and oil lubrication.In order to make the bearing function well, first of all, to choose suitable conditions for use, use the purpose of lubrication.If only considering lubrication, the lubricity of oil lubrication is dominant.However, grease lubrication has the advantage of simplifying the structure around the bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication.
