|SKF RLS 13 bearing
The raceway sound of INA bearings and its control method The raceway sound is a smooth and continuous sound produced by the rolling body rolling on the raceway surface when the bearing is running. It is a unique basic sound that occurs in all bearings. The general bearing sound is the raceway sound plus other sounds. The greater the rigidity of the bearing housing, the lower the sound pressure level of the raceway sound. If the radial clearance is too small, the sound pressure level and main frequency of the raceway sound will increase sharply as the radial clearance decreases.
INA bearing fatigue failure is a surface form of failure, mainly manifested as fatigue crack initiation, propagation and fracture process, the metal caused by the long-term impact of the load failure generated under alternation. Cracks in two ways . From the bearing surface, it is still from the cracks in the surface layer, these two goals (part carburization, quenching and other surface heat treatment, if there is uneven hardness, structure, and non-uniform internal stress and other disadvantages, then the contact stress Generally from the effect of producing the opposite underground cracks, if the surface quality of the parts is poor, there is a defect (oxidation, decarburization), poor friction or lubrication, cracks from the surface.
