Bearing is precision components, its use has to be carefully accordingly. No matter how high performance fag use bearing, if use undeserved, it will not be expected high performance. So what is the use of bearing method? In the use of bearings with must pay attention to the following:
1, keep bearing and its surrounding clean.
Even the small dust eyes see, also can give bearing bring bad effects. So to keep clean around, make dust from invading bearing.
2, carefully use fag in use give bearing bearing a strong impact, will produce the scars and impress, become the cause of the accident. Severe cases, will crack, fracture, so must pay attention to.
Three, use proper operating tools
Avoid to existing tools instead of, must use appropriate tools.
4, want to note bearing corrosion
Operation bearing, hands sweat will be the cause of rust. To pay attention to use clean hand operation, better try to bring gloves.
The rolling bearing remove when the examination, but according to bearing damage judgment of the bearing fault and the causes for the damage.
1. The groove surface metal peeling off
Bearings rolling elements and inner and outer surface rolling way all bear the role of periodic pulse load, which causes the cycles of contact stress. When the stress cycling times up to a certain value, in the rolling body or the inner and outer groove work surface fatigue is peeling off. If bearing load is too big, can make the fatigue intensified. In addition, fag installation is not straight, shaft bearing bending, also can produce groove spalling phenomena.
Rolling bearing of the tao will reduce shaft of spalling fatigue running accuracy, make the organizations that vibration and noise.
2. Bearing burns
Burn the groove, rolling bearing on the body back to HuoSe. The cause of the burn is usually insufficient lubrication, lubricating oil quality requirements or metamorphism, and bearing assembly too close, etc.
3. Plastic deformation
Fag of tao and roller bearings rolling contact surface appear evenly pit, explain bearing produce plastic deformation. The reason for this is bearing in a large static load or impact load, the work of the surface of the local stress more than material of the yield of limit, this generally occur in low speed rotating bearing.
4. Housings circle crack
Housings circle crack reason may be fag bearing with close, bearing foreign or inner circle, become loose, bearing tolerance a deformation, installation of poor surface processing bearings.
5. Keep a fracture
Its reason is insufficient lubrication, crushing roller, a circle skewed, etc.
6. Keep frame of metal in the rolling adhesion body
The reason is probably rolling elements are stuck in a cage in or insufficient lubrication.
