How is the "belt rate" vibration categorized in vibration analysis?

In vibration analysis, the "belt rate" vibration refers to the frequency at which belts operate, such as those found in conveyors or other mechanical systems. This vibration is categorized as sub-synchronous because it occurs at a frequency that is lower than the fundamental rotational speed of the driven shaft, typically associated with the rotational speed of the equipment.

Understanding this categorization is crucial as sub-synchronous vibrations can indicate problems such as misalignment, tension issues, or wear in the belt system. Monitoring the belt rate allows for effective diagnostics to maintain equipment reliability and performance. Thus, recognizing that the belt rate is sub-synchronous helps technicians and analysts diagnose potential issues effectively by distinguishing the frequency characteristics of the vibrations they encounter during their assessments.
