The professor's analysis pointed out that when the INA bearing works under radial load; the INA bearing inner load zone and non-load zone; if the INA bearing has a certain radial clearance; the non-load zone roll and inner roll are not completed; The effect of the centrifugal force may be touched by the outer ring; for this reason; at low rotational speeds; when the centrifugal force is less than the weight of the tumbler; the rolling collar will fall off the cake with the inner raceway or the cage and arouse the inherent sensation and noise of the INA bearing; Has the following characteristics:
1. INA bearings that also occur at different scales and have different scales have different speeds.
2. It is also easy to attack when only the radial load is applied and the radial clearance is large.
3. It may be that the sound may be intermittent.
4. When the fat is smooth, it is easy to attack; when the oil is smooth, it is not easy to attack. When using the smooth fat, it is more likely to contain tax.
5. Motivation voyage attack.
6. The persecution sensation often provokes the second-order and third-order tortuous sensation of the outer ring; then announces the transformation of the students.
