Rolling bearing lubrication purposes and methods


Rolling is also a class of common mechanical hardware products, which need to constantly be lubricated during use , in order to ensure its normal work , the main purpose of rolling bearings lubricated , what does ? Method of lubrication process and what it? Today small for you to make the following order, I hope to help more people to have a bearing on the kind of understanding and awareness of it !

The main purpose of lubrication of rolling bearings are:

1, to reduce friction and wear : mutual contact portion of the ferrule , and the rolling elements constituting the bearing holder to prevent the metal contacts , reducing friction and wear .

2 , to extend the fatigue life : the rolling bearing fatigue life, in rotation, the rolling contact surfaces oiled, then extended. Conversely, low viscosity oil , lubricating oil film thickness is not good , then shortened.

3 , the discharge of frictional heat , cooling : circulating oil to the oil discharge method can heat generated by friction or heat coming from the external cooling . Prevent bearing overheating, prevent oil itself aging.

4 , Other : There are also prevent rust , corrosion effect of foreign invasion of the bearing , or prevented.

Rolling bearing lubrication main methods:

Currently bearing lubrication methods are mainly two types of grease and lubricating oil in different ways ; in order to make a good play bearing function, first, to select the appropriate conditions , the use of lubrication purposes. If only consider 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 .
