Bearing quenching technology support methods

    Select the appropriate quenching medium were particularly important, it determines the bearing parts and properties after quenching, quenching medium is usually a solid, liquid and gas are three bearing quenching medium according to the change of state change of state is divided into fat and non-biological Hair biological state change classes.
    After the restoration of the right way bearing the same performance with the new bearings. The accuracy of its clearance and other parameters can meet the new requirements of the Swedish bearings, it is important to understand and recognize the degree of injury to select the correct repair program. Such as surface grinding process can be cleared to make some minor damage, but can not clear the real fatigue level, not the removal of debris caused by depression or wear. Therefore, if only to make the bearing surface grinding treatment, generally not suitable for serious damage bearings. And if after a comprehensive re-manufacturing repair process, the bearing fatigue layer is completely removed, but also a full replacement of rolling elements, cage, also have a full order, so that the bearing can achieve the performance requirements of the new bearings.
    Once the bearing damage occurs, you must go through a very rigorous testing process to determine whether the damage can be repaired bearing. Bearings must be repaired thorough cleansing, and then very strict comprehensive testing. The first is the detection of bearing damage as long as the existence of cracks, flaking and large overheating such as discoloration, the existence of these bearings is likely to damage beyond repair and must be scrapped.
    Bearing a rotating inner ring and outer ring raceway, the rolling contact with the rolling body is thus running track for the dark side, running track attached to the roller surface does not belong to an exception, which can be very variable load conditions, So remove the bearing case, strict attention and observation raceway running track. If you look at the trajectory, then this will only burden that radial load to bear large axial load, moment load to bear, or the extreme rigidity of the bearing housing inequality.
