Large metal noise
Reason 1: Abnormal load responses: Correction with research bearing clearance, load adjustment and correction block housing shoulder position.
Reason 2: Install the adverse responses: shaft, housing machining accuracy, improve the accuracy of installation, the installation method.
Reason 3: lack of lubricant or unsuitable responses: lubricant added, select the appropriate lubricant.
Reason 4: rotating parts in contact, Countermeasures: Modify the labyrinth seal contact portions.
Noise Rules
Reason 1: Because the foreign body causing the rolling surface indentation, rust or scratches, countermeasures: replacement of bearings, cleaning related parts, improve sealing device, use a clean lubricant.
Cause 2 :( steel after carburizing) surface deformation, countermeasures: replacement of bearings, pay attention to their use.
Reason 3: raceway stripping, countermeasures: replacement bearings.
Irregular noise
Reason 1: The clearance is too large, Countermeasures: A study with the bearing clearance and modify pre-load.
Reason 2: foreign invasion, Countermeasures: A study replacement of bearings, cleaning related parts, improve sealing device, use a clean lubricant.
Reason 3: Spherical injury, stripping, countermeasures: replacement bearings.
Abnormal temperature rise
Reason 1: too much lubricant, Countermeasures: reduce lubricant, used in moderation, choose a hard grease.
Reason 2: The lack of lubricant or unsuitable responses: lubricant added, select the appropriate lubricant.
Reason 3: Abnormal load responses: changes along with research bearing clearance, preload adjust, modify the position of the shoulder block housing.
Reason 4: Install adverse responses: improving machining accuracy of shaft and housing, accuracy of installation, the installation method.
Reason 5: The mating surface creep, seal friction is too large, countermeasures: replacement of bearings, with the study, modify, shaft and housing, change seals form.
Large vibration (shaft beating)
:( 1 reason carburizing steel rear) surface deformation responses: note bearing replacement operation.
Reason 2: Peel, countermeasures: replacement bearings.
Reason 3: Install poor Strategies: Modify the straight angle of the shaft, the housing block at right angles to the shoulder, the side of the pad.
Reason 4: foreign invasion, countermeasures: replacement of bearings, cleaning the parts, improve sealing devices.
Excessive lubricant leakage, discoloration
Cause: too much lubricant, dust and debris, wear powder produced foreign matter Countermeasures: the right amount of lubricant, lubricant selection change research, study the replacement of the bearing, clean housing.
