Bearing anomalies

Large metal noise reason 1: abnormal load, countermeasures: correction, the bearing clearance, adjustment and load, fixed shell over the shoulder position. Reason 2: bad installation, countermeasures: machining precision of the axis, a hood, improvement of installation accuracy, installation method. Reason 3: lack of lubricant or doesn't fit, countermeasures: added lubricant, select the appropriate lubricant. Reason 4: rotating parts there is contact, countermeasures: modify the sealing contact part of the curved road. Rules reason 1: noise caused by foreign body rolling surface indentation, rust or scars, countermeasures: change the bearing, cleaning related parts, to improve the sealing device, use a clean lubricant. Reason 2: ( After carburizing steel) Surface deformation, countermeasures: change the bearing, pay attention to their use. Reason 3: the raceway surface stripping, countermeasures: change the bearing. Random noise reason 1: the clearance is too large, countermeasures: research cooperation and bearing clearance, load changes. Reason 2: foreign invasion, countermeasure: the replacement of bearings, cleaning related parts, to improve the sealing device, the use of clean lubricant. Reason 3: spherical injury, stripping, countermeasures: change the bearing. Abnormal temperature rise reason 1: too much lubricant, countermeasures: reduce the lubricant, right amount used, select a hard grease. Reason 2: lack of lubricant or doesn't fit, countermeasures: added lubricant, select the appropriate lubricant. Reason 3: abnormal load, countermeasures: change to cooperate, the bearing clearance, adjust the preload, modify the shell over the shoulder position. Reason 4: bad installation, countermeasures: improve the machining precision and installation accuracy of shaft and the shell, installation method. Reason 5: cooperate with the creep, seal friction is too large, countermeasures: change the bearing, research cooperation, modify the shaft and the shell, change the sealing form. Vibration ( Axis of jitter, Reason 1: After carburizing steel) The surface deformation, countermeasures: pay attention to the bearing replacement operation. Reason 2: stripping, countermeasures: change the bearing. Reason 3: bad installation, countermeasures: modify the axis, a hood over the shoulder Angle, pad side of the straight Angle. Reason 4: foreign invasion, countermeasures: change the bearing, cleaning all parts, to improve the sealing device, etc. Lubricant leakage is overmuch, discoloration reason: too much lubricant, foreign invasion, wear powder to produce foreign body, such as countermeasures: use appropriate lubricant, study change select lubricant, research of bearing replacement, clean the shell.
