The vibration system consisting of steel degree, flexibility, mass and damping determined by the design parameters of self aligning ball bearing will generate vibration that is suitable for its operation under operation conditions.
The less the deviation caused by the deviation in the manufacturing process, the smaller the vibration. The ball surface roundness, waviness and surface roughness is the most important factor on the vibration of the self aligning ball bearing parts, the shape error and the surface of inner ring and outer ring raceway roughness is self aligning ball bearing again, cleanliness and lubricant quality etc..
Operating conditions such as installation conditions, speed, the direction of the load under the axial direction, the amount of value and so on.
Self aligning ball bearing rolling self aligning ball include deep groove ball bearing, self aligning bearing, ball linear motion self aligning ball bearing (thrust roller, ball, ball and so on), according to the above different criteria can be divided into the following aspects:
1. Tapered roller self aligning ball bearing
1. The inner and outer raceways are flaking, serious wear and crack in the inner and outer rings.
2. In the long direction of the roller, the forward shift of the center is more than 1.5mm, and the front-end of the cone roller is more than 2~3 mm.
3. The cage is worn, and the roller can not be closed in the inner ring. The rupture and deformation can not be repaired.
Two, plane self aligning ball bearing
1, two raceway washer peeling and serious wear.
2, breaking ball or pits.
3. The cage has a serious deformation and can not close the ball.
Three, deep groove ball self aligning ball bearing
1. The inner and outer raceways are flaking, serious wear and crack in the inner and outer rings.
2. The ball loses round or surface exfoliation, and there is a crack.
3. The wear of the cage is serious.
4, the rotation has the noise and the vibration, when the stop has the braking phenomenon and retrogression reversal.
5, the gap of self aligning ball bearing exceeds the maximum clearance.
