Stainless steel bearing raceway of the abnormal phenomena of maintenance

Stainless steel bearing raceway groove sound sound and its control method is when stainless steel bearing operation, its rolling on the surface of the raceway and rolling body send out the voice of a line of continuous, happened all stainless steel bearing characteristic of the basic sound. The general stainless steel bearing ring raceway is combined with other sounds. The stainless steel and the stiffness of the bearing, the greater the raceway of sound pressure level is lower. Such as radial clearance is too small, the sound pressure level and the main frequency of the raceway sound can increase sharply with the decrease of radial clearance. The surface of the stainless steel bearing fatigue failure is a failure form, the main performance for fatigue crack initiation, expansion and fracture process, under alternating load generated by the fault of the long-term effects of the metal. 1, reason: low overall eccentric stainless steel bearing precision method: using regulation accuracy grade of stainless steel bearing 2, reason: different method of heart: main shaft bending or casing hole repair spindle or box 3, reason: belt too tight method: make the elastic of the belt can be adjusted properly, reason: poor lubrication methods: use prescribed brand of lubricating materials and proper cleaning, reason: low assembly quality methods: improve the quality of assembly, reason: stainless steel bearing inner shell run laps method: stainless steel bearings and related worn parts 7, method of axial force is too big: cleaning, adjustment sealing ring clearance requirement 0. 2 to 0. Between 3 mm, correcting impeller balance hole diameter and check static balance method: 8, stainless steel bearing damage replace stainless steel bearing raceway control acoustic method: choose low noise bearing waviness namely small stainless steel stainless steel bearings, carefully select and use conditions. Race often affect the mechanical noise, reduce the raceway can reduce the mechanical noise.
