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 average) is higher The bearing vibration in the frequency band (speed) value. 3.3 Comparative Law vibration calibration (vibrationcalibrationbycomparison) It will be corrected with standard sensors sensors in the same vibration excitation, and to give each measurement measuring system Value, find the measurement error is the result of the comparison of the calibration, the calibration is called the comparison vibration calibration.

4 Overview

Speed bearing vibration measuring instrument is measuring the vibration speed rolling bearing special detection equipment, the principle is shown in Figure 1 As shown by the speed sensors, bearing vibration measuring instrument meter box (referred to above two parts vibration measurement system), bearing drive Actuating means, bearing mounting mandrel and axial (or radial) loads and other components. Vibration measurement system for measuring rolling
