Purpose and method of rolling bearing lubrication

Issuing time:2019-06-22 00:00

Rolling bearing is a kind of commonly used machinery and hardware products, the need to constantly in the process of use for lubrication, to guarantee the normal work, so what are the main purpose of the rolling bearing lubrication processing? What are the lubrication methods? Today, I will make the following arrangement for you, hoping to help more people have a better understanding of this kind of bearing.


The main purpose of rolling bearing lubrication is:


1. Reduce friction and wear: prevent metal contact and reduce friction and wear in the contact parts of the bearing sleeve, rolling body and retainer.


2. Extend the fatigue life: the rolling fatigue life of the bearing is extended if the rolling contact surface is well lubricated during rotation. Conversely, the oil viscosity is low, the thickness of the lubricating oil film is not good, then the shortening.


3. Discharge of heat of friction and cooling: circulating oil feeding method and other methods can use oil to expel heat generated by friction, or heat from external sources, and cool down. Prevent bearing from overheating and prevent lubricating oil from aging itself.


4. Others: it also has the effect of preventing foreign matter from invading the bearing's interior, or preventing rust and corrosion.


Main lubrication methods for rolling bearings:


At present, there are two main lubrication methods: grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose the suitable lubrication method for use condition and purpose. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the surrounding structure of the bearing and comparing the advantages and disadvantages of grease lubrication and oil lubrication.
