Common Problems And Countermeasures In Bearing Use
Problem 1: strong metallic sound
Abnormal load: select appropriate assembly clearance and preload;
Poor assembly: improve the machining accuracy of the shaft, improve the installation method;
Insufficient lubricant: supplement or use suitable lubricant.
Question 2: regular sound
Foreign body causes channel corrosion, indentation and scar: clean relevant parts and use clean grease;
Channel spalling: fatigue wear, replace bearing.
Third, irregular abnormal sound
Foreign body invasion: clean relevant parts and use clean grease;
Excessive clearance: pay attention to cooperation and select appropriate clearance;
Steel ball scar: steel ball fatigue spalling or foreign body sticking, replace the bearing.
Problem 4: abnormal temperature rise
Excessive lubricant: reduce lubricant;
Insufficient or unsuitable lubricant: increase lubricant or select suitable lubricant;
Creep of mating surface or oversized sealing device: modification of bearing outer diameter or inner diameter mating surface and change of sealing form.
Problem 5: the rotary vibration of the shaft is large
Spalling: fatigue spalling, bearing replacement;
Poor assembly: improve the machining accuracy of the shaft, improve the installation method;
Foreign body invasion: clean relevant parts and use clean grease.
