Torsional Analysis

The OROS analyzers provide the instantaneous angular speed inside each shaft revolution, thanks to the integrated frequency to RPM converter.
The analysis of this speed in frequency or time domain give helpful information for vibrations reduction during prototyping or for source identification while doing service diagnostics.
With torsional analysis, detect, follow the torsional resonance of the shaft and, for example, identify problems due to flexible coupling.

Gear Analysis

Complex vibration signature, due to high frequencies, is analyzed with the OROS FFT-Diagnostics tool:

• The correlation is useful to determine the correlated part of signals from different locations on a structure. This helps tracking the root and cause of vibration phenomena machinery structure and/or cinematic.
• The cepstrum is an efficient tool to detect periodic shocks in bearings or parts of rotating machinery. It is specially adapted when the spectrum levels are noised with their impulsive components.

Roller Bearings

Damaged roller bearings vibration spectrum are measured with an accelerometer mounted on the casing. The OROS FFT-Diagnostics module uses envelope demodulation to analyze vibration sources to determine if the source is from the roller elements or the races.
