Detect FAG auto bearing troubleshooting methods

Used in the work of the sound characteristics of the bearing, only in this way can accurate to judge whether there are abnormal, when the rolling auto bearing in the work, under the condition of normal, stable running, light, no stagnation phenomenon, the sound of harmony and no noise, can be heard even and continuous 'sound' sound, or lower 'rumbling' sound. Noise intensity is not big. Now that you have to understand the normal sounds FAG bearings, then we can according to these as a standard to determine the cause of the abnormal situations: first, when heard auto bearing uniform and continuous 'hissed. ' this sounds in internal and external figure by roller rotation, contains a metal has nothing to do with the speed of irregular vibration noise. General performance for the bearing inner fatliquoring quantity is not enough, should be added. If the equipment downtime is too long, especially during the winter low temperature circumstances, auto bearing during operation sometimes rustling 'hissing sound, it has to do with auto bearing radial clearance to smaller and smaller work grease penetration. Should be appropriately adjust the auto bearing clearance, replacement penetration bigger new grease. Second, when they see the auto bearing continuous 'sound' sound in the homogeneous periodic 'wow' the sound is due to the rolling element and the inner and outer ring raceway there scars, grooves, rust spot. Sound cycle and FAG is directly proportional to the speed of the bearing. Deal with auto bearing for replacement. Third, when there is a car bearing a discontinuous 'terrier infarction' this sound is due to cage or inside and outside the circle to crack. Must be replaced immediately stop the car bearing. Fourth, when found that car bearing a irregular and uneven 'scrape' the voice is due to the car bearings into the iron filings, sand and other impurities. Sound intensity is small, is not connected with the revolution. FAG bearings cleaning, add fat or oil change again. Fifth, see the work of a continuous and irregular auto bearing of the 'sasha vujacic' this voice and auto bearing inner ring and shaft fits too loose or outer ring and bearing hole fits too loose. Sound intensity is larger, FAG bearing inspection cooperation relations, found that the problem timely repair.
