Detection of IKO roller bearing troubleshooting methods

Use IKO bearing voice characteristics in the course of work, only in this way can accurate to judge whether there are abnormal, when the rolling bearing in the work, under the condition of normal, stable running, light, no stagnation phenomenon, 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 know the noise made by the roller bearing under normal condition, then we can according to these as a standard to determine the cause of the abnormal situations: first, when heard IKO 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 equipment downtime is too long, especially during the winter low temperature circumstances, roller bearing operation of rustling 'hissing sound, sometimes with the bearing radial clearance to smaller and smaller work grease penetration. Should be appropriately adjust bearing clearance, replacement penetration bigger new grease. Second, when found IKO bearing in successive 'sound' sound 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 is directly proportional to the speed of the roller bearing. Bearing for replacement. Third, when there are bearing a discontinuous 'terrier infarction' this sound is due to cage or inside and outside the circle to crack. Must be replaced immediately stop IKO bearings. Fourth, when found bearing a irregular and uneven 'scrape' the sound is due to the bearing inner into the iron filings, sand and other impurities. Sound intensity is small, is not connected with the revolution. Cleaning should be made for roller bearing with fat or oil change again. Fifth, see the work of a continuous and irregular bearing of the 'rustling' sound general IKO bearings with inner ring and the shaft fits too loose or outer ring and bearing hole fits too loose. Sound intensity bigger, roller bearing coordination relations for inspection, found that the problem timely repair.
