3.1 Bearing Vibration (bearingvibration)
Bearing during rotation, in addition to some inherent, by the function of the required motion between the bearing parts Other
Everything has a cycle characteristic movement are called bearing vibration.
Bearing vibration measured in this specification refers to. the bearing inner ring against the end face of the spindle shaft shoulder, and with a constant rotation
Speed rotation, the outer ring does not turn, bear certain axial or radial load, its rolling cross-section of the outer ring outer cylindrical track center
(Highest point) of the outer ring of the bearing radial vibration at the intersection.
3.2 bearing vibration (velocity) value (velocityofbearingvibration)
At a certain speed and load testing, select a circumferential direction of the outer cylindrical surface of the bearing outer race substantially three points equally spaced
Testing at low, medium and high frequency band respectively over three vibration velocity arithmetic mean, which is in the corresponding bearing
Vibration frequency band (speed) value. If the bearings need to test both sides, then take each band (three-point averag
