The geometry and structure characteristics of the 1 bearing;
The 2 metal deformation process of energy loss (converted into heat energy, the same below);
The 3 contact spot area of micro friction energy loss;
4 rolling block the energy loss (such as the outer surface roughness, dust sand), and runway circle loss, uneven surface and operation condition caused by the shock energy loss;
5 other energy loss. For example, roller and cage sliding friction, collision, ring sliding friction energy loss caused by the.
In order to reduce the coefficient of rolling friction, reduce the energy loss, in view of the above factors may adopt the following measures: improve rolling work surface hardness, reduce the contact spot area and deformation energy loss, grease lubrication to reduce body roll and ring, keep the sliding frame, vibration relaxation and cleaning the raceway on the dust, debris; to reduce the surface roughness, reduce rolling resistance; improve the precision and assembly precision; improve the bearing installation conditions or operating conditions, reduce the shock bearing movement, etc.. The rolling bearing manufacturing level and apply, we improve the running quality of one of the key technology of bearing lubrication is still good.
