Common problems and countermeasures of bearings.
Strong metal volume
1. Abnormal load: select appropriate assembly clearance and preload.
2. Poor assembly: improve the machining accuracy of the shaft and improve the installation mode.
3. Insufficient lubricating oil: Supplement or use appropriate lubricants.
Rules of the sound
1. Foreign bodies cause corrosion of the trench. Indentation. Damage: Clean related parts with cleaning grease.
2. Ditch stripping: fatigue wear, bearing replacement.
Asymmetric heterophony
1. Foreign invasion: clean relevant parts and use clean grease.
2. Clearance is too large: pay attention to coordination, and choose the appropriate clearance.
3. Bearing ball damage: the ball falls off or is blocked by foreign bodies. Replace the bearing.
Abnormal temperature rise
1. Excess lube: Reduce lube.
2. Insufficient or inappropriate lubricating oil: increase lubricant or choose appropriate lubricant.
3. Mating surface creep or sealing device is too large: bearing outer diameter or inner diameter mating surface modification, change the sealing form.
Rotating shaft vibration is large.
1. Stripping: fatigue stripping, bearing replacement.
2. Poor assembly: improve the machining accuracy of the shaft and improve the installation method.
3. Invasion of foreign objects: clean relevant parts and use cleaning grease.
Bearing lubricating oil leakage, serious discoloration.
