Response to FAG burn should pay attention to matters of cylindrical roller bearing

Fracture refers to as the cylindrical roller bearing raceway wheel rim or local part of the roller Angle are exerted impact or excessive load and a small number of fracture. Appear this kind of circumstance is the cause of FAG bearing has taken a knock during installation. The load is too large. Using bad fall, etc. The corresponding measures to improve the installation method ( Adopt the hot charging, using the appropriate tool holder) 。 Correct the load conditions. FAG bearing installed, supporting to guard. FAG bearings card injury occurs when the state of the so-called card injury is due to the cylindrical roller bearing in FAG injury parts of small burns summary of surface damage. Slide face, rolling surface circumferential direction of linear scars. End of the roller set linear scar near the end of the roller shaft torus card. FAG bearings card injury occurs too much too much load, the cause of preloading. Bad lubrication. Foreign body nip. The inner ring of the outer ring tilt, the deflection of shaft. The precision of shaft, bearing box. FAG bearings card injury occurs when the size of the measures to check the load. Preloading is appropriate. Improve lubricant and lubricating method. Check the shaft, the precision of the bearing housing. Bearing state of burn injury refers to: the bearing raceway wheel, roller and cage in the rotation sharply fever until discoloration, softening, deposition and damaged. The second is probably too big load ( Preloading is too big) 。 Speed is too large. Clearance is too small. With water or other foreign matter invasion. If the above two cases are not the shaft, the accuracy of bearing box, shaft deflection. See here, I think everyone wants to know the solution, first of all, to study lubricants and lubrication method, choose the right bearing lubricant, and its dosage, and the selection of the bearing must be corrected. Research to cooperate, cylindrical roller bearing clearance and preloading, and improve the sealing device. Check the shaft and the precision of the bearing housing. Test results, if found damage and cylindrical roller bearing abnormal situation, please according to the bearing damage phenomenon to find out the reason, to develop countermeasures. In addition, the test results, if there are several kinds of defects, cylindrical roller bearing can't use, need to replace new bearing. 一个。 Inner and outer ring, rolling body, to keep any of them are cracks and debris. b。 Inner and outer ring, rolling body any one strip. c。 Raceway surface, guard, significant injury of roller. d。 Maintains a badly worn or loose rivet badly. e. Raceway surface, rust and roller has a scar. f。 Had a remarkable indentation rolling surface, rolling body and make a mark. g。 Inner ring diameter or outer diameter on the creep. h。 Discoloration of overheating. 我。 Sealed bearing grease sealing and dust cover breakage to serious.
