Gearbox Condition Monitoring

What this topic covers

Vibration, oil debris, temperature and performance indicators for geared equipment.

Core ideas

Gearboxes concentrate loads through meshing teeth and supporting bearings.

Tooth damage, lubrication problems and misalignment can alter vibration and debris patterns.

Load and speed should be considered when comparing trends.

Program tradeoffs

Load, speed and operating state can change signals even when machine condition is unchanged.

What good evidence looks like

Diagnosis should combine vibration, temperature, lubrication, process and maintenance history where appropriate.

Lifecycle perspective

Monitoring should produce actionable work or engineering review rather than accumulating alarms without response.
