Vibration caused by the bearing manufacturing errors
Rolling bearing, the outer ring raceway and the rolling surface along the circumferential direction different levels of the wavy processing traces - waviness, which is caused by bearing vibration induced noise and the Imperative of the axis of rotation axis of the eccentric motion a very important factor in . Vibration caused by processing traces the formation of waviness for bearing radial clearance, or can also occur in addition to other bearings of the outer ball bearing axial load is applied, in addition to the raceway waviness wave number lot of bearings, can also occur when subjected to radial load.
Manufacturing factors bearing rolling surface waviness, who wish to control its influence on the bearing vibration, only by increasing the rolling surface of the machining accuracy, reducing the shape of the raceway surface error to seek to resolve. To the modern technical level, this effort has been progress, but can not completely eliminate this important source of vibration and noise. Should be noted that the bearing manufacturing, installation factors bearing and shaft and bearing rigid conditions may make the bearing raceway surface waviness, and their influence is often greater than the manufacturing factors.
