Heze bearing, Heze 3...slewing bearing / ' (3,3,3) -, steel ball and ring channel surface defects
/ ' (3,3,3) - when the steel ball or ring When there are defects on the surface of the ring channel, scratch noise similar to pulse sound will be generated. If the defect is on the working surface of the ferrule, the scoring noise will always be generated continuously and has a certain periodicity. If the defect is on the surface of the steel ball, there may be no scoring noise and no periodicity.
/ ' (3,3,3) -, the spherical deviation, waviness and roughness of the steel ball
/ ' (3,3,3) -The steel ball has the greatest impact on the vibration and noise of the bearing It is obvious that the spherical deviation of the steel ball causes the bearing to produce low-frequency vibration and abnormal sound, the corrugation of the surface of the steel ball causes the bearing to produce high-frequency vibration and abnormal sound, and the roughness causes the bearing to produce composite frequency noise.
/ ' (3,3,3) -:, the roundness and waviness of the ring channel
/ ' (3,3,3) - If the roundness of the bearing ring channel surface And unreasonable waviness control will cause the bearing to produce high-frequency alternating or buzzing sounds. The roundness of the groove, especially the roundness below the edge, has a significant impact on the abnormal sound of the bearing. The density of the ferrule surface waviness has a great influence on bearing vibration and abnormal sound. The influence of dense waves is much greater than that of sparse waves.
/ ' (3,3,3) -, Structural parameters of the cage
/ ' (3,3,3) -When the bearing rotates, the cage and the rolling elements collide with each other to produce a cage noise. The generation of cage noise is closely related to the cage's structural type, structural parameters, guide clearance, radial momentum, pocket clearance, surface roughness, etc. Reasonable selection of the above parameters will help control the abnormal sound generated by the cage.
