Large metal noise cause 1: abnormal load; countermeasures: correction cooperation; study of painful bearing clearance; adjustment and load; /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Reason 2: Poor equipment; countermeasures: machining accuracy of shaft and outer casing; improvement of equipment precision and equipment method.
Reason 3: Lack of lubricant or unsuitability; countermeasures: make up the lubricant; pick the right lubricant.
Reason 4: The rotating part has a touch; Countermeasure: Correct the touch of the curved road seal.
Rule noise cause 1: Indentation, rust or scratch caused by foreign matter forming the rolling surface; Countermeasures: Replace the painful bearing; remove the relevant parts; improve the sealing equipment; use a clean lubricant.
Reason 2: (after steel carburizing) appearance deformation; countermeasures: replace the painful bearing; pay attention to its application.
Reason 3: Rolling surface peeling; countermeasure: replace the painful bearing.
Irregular noise cause 1: excessive clearance; countermeasures: study cooperation and painful bearing clearance; correct preload.
Cause 2: foreign matter intrusion; countermeasures: study and replace the painful bearing; remove the relevant parts; improve the sealing equipment; use clean lubricant.
Reason 3: Spherical injury, peeling; Countermeasure: Replace the painful bearing.
Abnormal temperature rise causes 1: excessive lubricant; countermeasures: reduce lubricant; excessive use; pick harder grease.
Reason 2: Lack of lubricant or unsuitability; countermeasures: make up the lubricant; pick the right lubricant.
Reason 3: Abnormal load; countermeasures: correct cooperation; study the clearance of the painful bearing; adjust the preload; correct the shoulder orientation of the outer casing.
Reason 4: Poor equipment; Countermeasures: Improve machining accuracy, equipment accuracy, and equipment methods for shafts and casings.
Reason 5: creep of the cooperation surface, excessive conflict of sealing equipment; countermeasures: replacement of the painful bearing; research cooperation; correction of the shaft and outer casing; change of the sealing method.
Large oscillation (bounce of the axis)
Cause 1: (after steel carburizing) appearance deformation; countermeasures: focus on the replacement of the pain bearing replacement operation.
Reason 2: Peeling; Countermeasure: Replace the painful bearing.
Reason 3: Poor equipment; countermeasures: Correct the right angle of the shaft, the outer shoulder of the shell, and the side of the liner.
Reason 4: foreign matter intrusion; countermeasures: replace the painful bearing; remove the parts; improve the sealing equipment.
Lubricant leaks too much; color change causes: excessive lubricant; foreign matter intrusion, wear of foreign matter in the powder; countermeasures: excessive use of lubricants; research and conversion of selected lubricants; research on the replacement of the painful bearing;
Note: The above anomalies are the same as other common bearings!
