Rolling bearing lubrication methods and advantages and disadvantages of 1, the purpose of lubrication of rolling bearing lubrication goal is to reduce the bearing internal friction and wear, prevent burning stick, the lubrication effect is as follows: 1) Reduce the friction and wear in the form of bearing ring, rolling body and touch each other part of the cage, prevent metal contact, reduce friction and wear. 2) Extend the fatigue life of rolling element bearing fatigue life, in the rotation, good lubrication performance of the rolling contact surface, are extended. On the contrary, the oil viscosity is low, the thickness of lube film is not good, is shortened. 3) Eliminate friction heat and cooling cycle to oil to oil discharge produced by friction heat, or by an external sound of hot, have the effect of cooling. To prevent hotbox, prevent aging oil itself. 4) Other also has to prevent foreign matter into the bearing internal, or to prevent rust and corrosion effect. 2, lubrication methods and advantages and disadvantages of the bearing lubrication method, grease lubrication and oil lubrication, respectively. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. But the fat lubrication expertise around a simplified bearing structure.
