Sound character using INA bearings in the work, the only way to accurately judge whether there is an exception, when the scroll when INA bearings in work, normally is, stable running, brisk, no stagnation, sound harmonious and without noise, you can hear uniform continuous "splashed" sound, or a lower "roaring" sound. Noise intensity is low. Now that you know what the normal state INA bearing the voice of, then we can as a standard to judge under these unusual circumstances because:
First, when heard INA bearing makes a uniform and continuous "hissing" sound effects of internal and external rotation resulting in the figure by containing irregular regardless of the speed metal vibration noises. General performance for the bearing and FAT volume, the supplement should be. If downtime is too long, especially in the case of winter low temperature, INA bearing sometimes occurs in operation "hissing rustling" sounds, the INA bearing radial clearance smaller, related to grease penetration small. Appropriate adjustments should be INA bearing clearances, replaced needle penetration of large new grease.
Second, when found INA bearings in continuous "splashed" sound make a uniform periodicity in "Wow Luo" the sound is due to the rolling elements and the inner and outer ring raceways caused by injuries, Groove, rust spot appears. Is proportional to the speed of the sound of a cycle and the INA bearing. INA bearings should be replaced.
Third, when INA bearing discrete issue of "MI MI" the sound is caused due to a cage or rupture of inner and outer rings. Must be replaced immediately shut down INA bearings.
IV, issued when INA bearings are found in an irregular, uneven "swish swish" sound is due to INA bearings in the hands of scrap iron, caused by impurities such as sand grains. Sound intensity of a smaller, and there is no connection to a few. INA bearing should be clean, fat or oil change again.
V, saw INA bearings in continuous work and irregular "swish swish" sound General and INA bearing inner ring and shaft fit too loose or the relationship between outer ring and bearing hole fit too loose. Sound intensity is the larger, should check the cooperation relationship of INA bearing, find problems repaired in a timely manner.
