Common burn FAG self-aligning ball bearing failure of three major reasons

Self-aligning ball bearing failure of the three major reasons: common burns bearing lubrication bad; FAG bearing too much load; Axis, the precision of the bearing housing is the cause of bearing burns, bearing burnt under the following details for you. Bearing burn one of the reasons is due to the bad lubrication self-aligning ball bearings, may use the informal lubricant, or lubricant too much, too little, is not correct. Too much second reason is bearing load bearing burns; The speed of the bearing is too big; Bearing clearance is too small; With water or other foreign matter invasion. Burn the reason a third axis bearing, the accuracy of bearing box, shaft deflection. Bearings burned three reasons can cause bearing burn status will appear FAG bearing raceway wheel, roller and cage in the rotation sharply fever until discoloration, softening, deposition and damaged. Advice when used in bearing, pay attention to the installation, lubrication, clearance and so on each link all do it accurate as far as possible, reach the designated position, so it can reduce the bearing burns and prolong the service life of bearing. Bearing causes of noise is more complex, one is the bearing inner and outer surface wear. Due to the wear and tear, damage and shell, rolling bearing and the bearing axis of cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. Self-aligning ball bearing wear loose after kuang, maintains a looseness damage, also can produce sound. ( 1) Bearing damaged, should be replaced immediately. ( 2) Bearing grease is too little, too much, or has the impurity such as iron filings. Grease bearing capacity should not be more than 70% of the total volume, have impurities should be replaced. ( 3) Axis and FAG bearing fit too tight or too loose. Should be tight to grinding, must be set to a shaft with too loose. ( 4) Bearing and end cover fit too tight or too loose. Too tight when processing the bearing chamber, too loose inside the end cover set steel bushing. ( 5) Two motor end cover or bad bearing cover assembly. Will end cover or bearing cover check into mouth, flat, tighten the screws. ( 6) The belt too tight or bad coupling assembly. Adjust the belt tension, coupling correction. ( 7) Self-aligning ball bearing lubricating oil is too little, have impurities or oil ring stuck. Should such as refueling, change new oil, repair or replace the oil ring.
