: High-frequency ultrasonic emissions (invisible in standard velocity spectrums).

Characterized by high axial vibration at 1X and 2X running speed , with a 180-degree phase shift across the coupling.

RPM in the direction. Phase shift across the coupling is approximately 180∘180 raised to the composed with power Parallel Offset Misalignment: Characterized by high Vibration Analysis Wall Chart Pdf

Digital PDFs allow users to instantly look up specific acronyms (such as "BPFO" or "Subharmonic") without scanning a massive physical poster.

A comprehensive Vibration Analysis Wall Chart will typically be divided into several core diagnostic sections. Understanding how to navigate these sections is crucial for accurate fault diagnosis. 1. Frequency Grouping If you primarily use or continuous online sensors

These include bearing defects (BPFO, BPFI) and electrical faults that do not occur at exact multiples of the shaft speed.

Integer multiples of the running speed (e.g., 2X, 3X), typically indicating mechanical issues like misalignment or unbalance.

Quick notes on the relative phase shifts between different measurement points (axial, radial, horizontal, vertical). Characterized by high axial vibration at 1X and

Standard charts, such as the Illustrated Vibration Diagnostic Wall Chart from Technical Associates or versions from RMS Ltd , typically include:

Use the PDF's "Recommended Action" column to write your work order. Example: "High 2X RPM with 180° phase shift—schedule laser alignment."

Tighten structural bolts, check baseplates, and inspect for wear in the bearing clearances. Gear Defects Frequency: Often found using gearmesh frequency ( fgmf sub g m end-sub
