Upon inspection, the grease was found contaminated and separating, with noticeable "dents" or craters on the outer race.

A mining site faced recurring failures in vibrating screen gearboxes. Practical Case Studies On Vibration Analysis Pdf

Key takeaway:

High-frequency filtering techniques (such as PeakVue or Spike Energy) used to detect early-stage bearing and gear defects by isolating stress waves. Upon inspection, the grease was found contaminated and

300 kW gearbox, input 1450 RPM, output 290 RPM. Symptom: Intermittent high-frequency “clacking” under load; no change in housing temperature. input 1450 RPM

: Initial vibration levels on both fan bearings were found to be very high even under "no load" conditions.
