When design reference surfaces become excessively deformed and unusable, alternative surfaces must be selected as references, necessitating the reorganisation of dimensional chains. For instance, if the bearing housing exhibits significant deformation, the rotating assembly should serve as the reference.
Bearing dust covers and seals serve as vital barriers protecting the internal grease within bearings. They effectively prevent external particulates from entering while retaining the lubricant.However, different seal types exhibit varying levels of protection
During the rotation of rolling bearings, the free vibration of the cage and its impact with rolling elements or rings can generate noise.This noise may occur in various bearings, but it exhibits a low sound pressure level and is characterised by low frequency. Its features include
The cooling process following metal quenching significantly influences deformation. Hot oil quenching results in less distortion than cold oil quenching, typically maintained at 100±20°C. The cooling capacity of the oil is also crucial to deformation.
