Bearing the typical sound characteristics and causes

The reason why - voice describing character Ga ga zha ring sample not changes over turning speed ( Dust/foreign material) Sound changes over turning speed, Scratch) , dust/foreign material, orbital plane, ball bearings, roller surface roughness, orbital plane, ball bearing, roller bearing surface scratch yi's small orbital plane, ball bearings, roller surface roughness yi! - Introduction on and off, and the rules of the occurrence, and seal department contact, contact with the retainer and hermetic seal blare di di roar rings by turning speed changes, size are changed. According to the specific speed rotary sound bigger. Sometimes this is approximate alarm or flute. Resonance, cooperate with bad ( Axis shape bad) , orbital plane deformation, orbital plane, ball bearings, roller corrugated ( Large bearing such as a slight sound, it's normal) Crunching manual rotates, the feeling of orbital plane, scratch, The rules) The scratch, ball bearing, roller ( Irregular) Dust/foreign material, orbital plane deformation ( Part of the gap) Rumbling large bearing there was a continuous sound small bearings, high-speed rail, ball bearing, roller surface scratch blare - Om - Cut off power supply when the moment to stop, the motor electromagnetic sound cheep cheep, irregular ( Non rotational speed changes) , mainly for small bearings, with dust/foreign material jingle ring rules of tapered roller bearing and high speed continuous tone of large bearing small bearings, such as the retainer clear voice is normal, such as at low temperature grease by discomfort - gentle is good for maintaining internal abrasion, inadequate lubrication, insufficient bearing load operation. Hey! Hua when low speed at high speed is more obvious in continuously the impact of the retainer, internal, and insufficient lubrication. Reduce internal clearance or different tones disappear after preloading. Occurred, so all of the roller, the roller of the impulsive sound. Bang bang metal impact of louder sound of low-speed large thin wall bearing ( TTB） And so on. , rotating body tearing sound, sound track, squeaking wheel deformation MAO MAO mainly changes because of turning speed cylindrical roller bearing, can hear the sound loudly. After added lubricant, will stop at the moment. , lubricating oil too thick, the radial internal clearance is too large, lack of lubricating oil 摪 摪 between metal occlusal sound sharp sound, roller bearing roller and penal bites, internal clearance is too small, lubricating oil insufficient yi's small irregular voice of the bearings, lubricating oil in the bubble plosive PaCha PaCha irregular squeaking, with part of the skid, install the cheep cheep ring ring, key, etc in general the sound pressure is too large, orbital plane, roller, ball bearing, rough surface due to friction, orbital plane, roller, ball bearing, deformation due to friction, internal clearance is too large
