Low Criticality Gearbox
From Imrtwiki
Return to Gearbox Asset Management Strategies
Criticality/ Risk Cost = < $1000/year >$100/year
Suggest 1 year frequency of routine monitoring. Ideal is the gearbox is operational but is not a mandatory requirement.
Brg/gear fatigue/wear Brg Temperature PdM
Baseline only - Bearing casing temperatures higher speed shafts
Brg/gear fatigue/wear Visual PdM
Check build-up or debris or guards rubbing around input or output shaft
Brg/gear fatigue/wear Lube Wear Debris PdM
Removable magnetic Chip collector – Quantitative analysis and trend
Brg/gear fatigue/wear HS Gear/Brg Prob PdM
Baseline only - Vibration monitoring(VA) high speed shafts (simple vibration meter)
Brg/gear fatigue/wear LS Gear/Brg Prob PdM
Listening rod (or equivalent) audible noise analysis if gearbox is operational
Brg/gear fatigue/wear Lube Condition PdM
Portable oil dialelectric testing (lube condition)
Brg/gear fatigue/wear Lube Contam. PdM
Check breather desiccant colour change. Change if req.
Baseline only - Patch testing on-site- comparison chart ISO cleanliness
Brg/gear fatigue/wear Lube Temp PdM
Oil Temperature or equivalent (eg. lower casing temp) if gearbox is operational
Brg/gear seizure Lube Level PdM
Oil level check & filtered top up if required
Check for visual indications of oil leaks
Coupling Inefficiency Coupling Temp PdM
Non-contact temperature of input coupling if gearbox is operational
Non-contact temperature of output coupling
