The stiffness, stiffness, mass, damping, etc., of the vibration system determined by the design parameters of the bearing structure will produce vibrations corresponding to its mechanics under operating conditions.
Manufacturing process of the deviation caused by vibration, the smaller the deviation, the smaller the vibration. The roundness, waviness and surface roughness of steel ball surface are the most important factors of vibration in the bearing parts, followed by the shape error and surface roughness of the inner ring and outer ring channel, followed by bearing cleanliness and lubricant Quality and so on.
Operating conditions such as installation conditions, speed, axial load direction, magnitude and so on.
Rolling bearings include deep groove ball bearings, linear motion bearings, thrust bearings (roller, ball, ball), etc., according to the above types of different criteria can be divided into the following areas:
First, tapered roller bearings
1, the inner and outer ring raceway peeling, serious wear, inside and outside the ring cracks.
2, the length of the roller direction, the center forward volume of more than 1.5mm, tapered roller from the outer edge of the front edge of more than 2 ~ 3 mm.
3, cage wear, the roller can not Shoulong in the inner ring, rupture, deformation can not be repaired.
Second, the plane bearings
1, two roller washer stripping and severe wear.
2, ball broken or pitting.
3, cage deformation is serious, can not Shoulong ball.
Third, deep groove ball bearings
1, the inner and outer ring raceway peeling, serious wear, inside and outside the ring cracks.
2, the ball rounded or surface spalling, a crack.
3, cage wear serious.
4, there are noise and vibration when turning, stop when the braking phenomenon and reverse the reverse.
5, the bearing clearance with the provisions of the maximum clearance.
