Effect Of Lubrication On The Vibration Characteristics Of Ball Bearings

Used specifically design making of test bearing and computer digital type vibration measurement analysis system, research has lubrication on center axis to load role Xia deep ditch ball bearing vibration and noise of site value and the frequency characteristics of effect. results showed that: full lubrication can effective to reduced bearing of vibration and noise level; lubrication not full or lubricant not clean can makes vibration and noise increased, induced contact resonance and howling, and makes contact surface produced minor injury; no lubrication Shi bearing vibration sharply increased, and caused wear failure; Meanwhile, the lubricant film "stiffening effects" bearing the natural frequency of the elastic contact vibrations increase.
