The purpose of bearing lubrication
2015-07-01 by zysbearing
The purpose is to reduce the lubrication of rolling bearings inside the bearing friction and wear, to prevent burning stick, its lubrication utility as follows.
(1), to reduce friction and wear.
Mutual contact portion of the ferrule, and the rolling elements constituting the bearing retainer, to prevent the metal contacts, reducing friction and wear.
(2), to extend the fatigue life.
Bearing rolling contact fatigue life, in rotation, the rolling contact surfaces oiled, will be extended. Conversely, low viscosity oil, lubricant film thickness is not good, it is shortened.
(3), the discharge of frictional heat, cooling.
Circulating oiling method, etc. can be discharged oil heat generated by friction or heat coming from the external cooling. Prevent bearing overheating and prevent oil itself aging.
(4) Other
Also prevent dust and debris inside the bearing, or prevent rust, corrosion effect.
Lubrication methods:
Bearing lubrication methods, divided into grease and oil lubrication. In order to play well bearing measurement function, first, to select suitable conditions, using purpose of lubrication method. If only consider the lubrication oil lubrication dominant. However, there can be simplified specialty grease around the bearing structure, the grease and oil lubrication compare the pros and cons.
