Vibration frequencies at higher multiples of the rotating speed correspond with the number of components in a specific rotating part, such as the number of balls in a bearing. Other sources of vibration frequencies at multiples of the rotating speed may include fan blades, impeller vanes, rotor bars or stator slots, or some combination thereof.
Effective Monitoring of Cooling Towers A case study in using vibration analysis to monitor cooling towers at a Potash mine in Canada Effective Preventive Maintenance In 1993, the Skoghall Mill installed extensive on-line equipment for the shock pulse measuring of bearings on Board Machine No. 7 (BM 7). Thanks to this investment, today they can ...

Below are the formulas from ISO 7919 that define the vibration Zone boundary limits as a function of machine operating speed (rpm).
Strip vibration applies a dynamic component on the rolling force acting on the work roll and may excite the resonance of the mill stand.This problem moti-vates predicting the cluster mill dynamics by using a numerical model. It may help in planning the maintenance operation of rolls and bearings and in reducing the service costs. A complete

Measuring Fan and Motor Vibration ... Motor and Fan Bearings Vibration sensors should be placed in the radial (vertical & horizontal) and axial locations on the motor and fan bearings. This will provide the best detection of all vibration components including:
deflection and vibration. The milling head can be tilted right or left up to 90 degrees. Precision machine tools spindles equipped with taper roller bearings and a spindle concentricity of .0005" at the spindle nose. The cross slide table is precision ground with t-slots, adjustable limit stops, scale and three metal adjusting hand wheels.
In their models, the effects of different factors such as natural frequency of the shaft and bearing assembly, varying the number of balls, ball passage frequency, spindle speed variation, preload, misalignment, and manufacturing defects influencing ball bearing vibration were investigated.
The Vibration Parameters, Acceleration, Velocity and Displacement. Measuring Units When we looked at the vibrating tuning fork we consid- ered the amplitude of the wave as the physical displace- ment of the fork ends to either side of the rest position.
Machinery Vibration Limits and ... The vibration levels at or near the four bearings were recorded initially. The unfiltered readings ... The vertical scale for coherence functions varies from zero to one as shown in Figure 5. Peaks in the transfer function plots represent resonances. That is, vibration velocity is …
with 2 times rotational vibration. Problems in a motor such as a rub, loose parts, a bent shaft extension or elliptical bearing journals can cause vibration at 2 times rotational frequency. Due to it's closeness in frequency to twice line frequency vibration the two levels will add when they are in phase and
