2020-09-01
Geometric size and structure characteristics of the bearing;
Metal deformation process can damage (
Is converted into heat energy, same below)
;
3.
Contact spot in the micro sliding friction loss;
4.
Crush block content can damage (
Such as the outer ring rough surface, have dust sand, etc. )
, and runway circle, the surface is rough and running conditions can impact vibration damage;
Can other losses.
Such as roller and cage of sliding friction, collision, retaining ring can damage caused by sliding friction, etc.
In order to reduce the coefficient of rolling friction, can reduce the loss, in view of the above factors can adopt the following measures: improve rolling working surface hardness, can reduce the contact spot area and the deformation, fatliquoring lubrication to reduce rolling body and sliding friction ring, cage, reduce dust sand vibration and clean up the roll channel, abrasive dust;
To reduce the surface roughness to reduce rolling resistance against;
Improve the geometry precision and assembly precision;
Improve the conditions of bearing installation or running conditions, reduce the vibration impact when bearing movement, etc.
In terms of one's current level of rolling bearing manufacture and use, good lubrication is one of our key technology to improve the quality of bearing operation.
