INA Bearings-SSHB China

This is particularly true where multiple defects are present.

However, depending upon the dynamic range of the equipment, background noise levels and other sources of vibration bearing frequencies can be difficult to detect in the early stages of a defect.

Bearing vibration signals are rarely straight forward and are further complicated by the interaction of the various component parts but this can be often used to our advantage in order to detect a deterioration or damage to the rolling surfaces.

Ball pass frequencies can be generated as a result of elastic properties of the raceway materials due to variable complianceor as the rolling elements pass over a defect on the raceways.

The frequency generated at the outer and inner ring raceway can be estimated roughly as 40% (0.4) and 60% (0.6) of the inner ring speed times the number of rolling elements respectively.

Eventually this motor failed catastrophically and thermal loading (cross location) of the bearings was confirmed.

A number of harmonics and sum and difference frequencies are also evident in the spectrum.

If the bearing speed ratio is below predicted values it may indicate insufficient loading, excessive lubrication or insufficient bearing radial internal clearance which could result in higher operating temperatures and premature failure.

Likewise a higher than predicted bearing speed ratio may indicate excessive loading, excessive bearing radial internal clearance or insufficient lubrication.

The bearing speed ratio (ball pass frequency divided by the shaft rotational frequency) is a function of the bearing loads and clearances and can therefore give some indication of the bearing operating performance.

Speed changes will cause shifts in the frequency spectrum causing inaccuracies in both the amplitude and frequency measurement.

In variable speed equipment sometimes spectral orders may be used where all the frequencies are normalised relative to the fundamental rotational speed.

This is generally called °?order normalisation, the fundamental frequency of rotation is called the first order.

Generally the bearing characteristic frequencies will not be integer multiples of the inner ring rotational frequency which helps to distinguish them from other sources of vibration.

Since most vibration frequencies are proportional to speed, it is important when comparing vibration signatures that data isobtained at identical speeds.

However, in practice this is rarely the case and due to a number of factors the rolling elements undergo a combinationof rolling and sliding. As a consequence the actual characteristic defect frequencies may differ slightly from thosepredicted, but this is very dependent on the type of bearing, operating conditions and fits.
