Purpose of bearing lubrication:
The purpose of rolling bearing lubrication is to reduce the friction and friction loss of the bearing, to prevent burning, its lubrication effect is as follows.
. Reduce friction and friction.
In the bearing ring, rolling body and retainer contact parts, prevent metal contact, reduce friction, wear.
Extend fatigue life.
The rolling fatigue life of the bearing is prolonged if the rolling contact surface is well lubricated during rotation.Conversely, oil viscosity is low, lubricating oil film thickness is not good, then shorten.
. Discharge friction heat, cooling
The circulation oil method can remove the heat generated by friction, or heat from the outside, cooling.Prevent the bearing from overheating and prevent the lubricating oil from aging.
(4). Other
It also has the effect of preventing foreign matter from intruding into the bearing, or preventing rust and corrosion.
Lubrication method:
The lubrication method of bearing is divided into grease lubrication and oil lubrication.In order to make the bearing function well, first of all, to choose suitable for the use of conditions, use purposes of lubrication method.If only lubrication is considered, the lubricity of oil lubrication prevails.However, grease lubrication has the advantage of simplifying the structure around the bearing.
