Daily Checks
Time required: 2-5 minutes per coupling
Visual Inspection
- Check for grease leakage
- Look for unusual discoloration
- Inspect guards condition
- Note any unusual noise
- Observe for excessive vibration
Recording
Document any observations in maintenance log.
Weekly Checks
Time required: 5-10 minutes per coupling
Temperature Monitoring
- Measure coupling temperature
- Compare to baseline
- Note ambient temperature
- Flag if >20°C above normal
Normal Temperature Ranges
| Operating Condition | Expected Temp |
|---|---|
| Aligned, properly lubricated | 40-60°C |
| Moderate misalignment | 50-70°C |
| Investigation required | >80°C |
Monthly Checks
Time required: 15-30 minutes per coupling
Visual Inspection (Enhanced)
- Detailed examination of seals
- Look for contamination
- Check fastener tightness
- Inspect grease nipples
- Evaluate guard condition
Grease Condition (Visual)
- Check grease color at seals
- Look for water contamination signs
- Assess grease consistency
- Plan relubrication if needed
Quarterly Checks
Time required: 30-60 minutes per coupling
Relubrication
- Clean grease nipples
- Add grease per specification
- Pump until fresh grease appears
- Wipe excess from seals
- Record quantity added
Grease Quantity Guidelines
| Coupling Size (OD) | Approx. Quantity |
|---|---|
| 100-150mm | 50-100g |
| 150-250mm | 100-250g |
| 250-350mm | 250-500g |
| 350-500mm | 500-1000g |
Documentation
Record in maintenance log:
- Date and time
- Grease type used
- Quantity added
- Observations
- Technician name
Annual Inspection
Time required: 1-2 hours per coupling
Complete Inspection
- Perform during scheduled shutdown
- Remove guards for access
- Check alignment (record values)
- Inspect coupling externally
- Evaluate for continued service
Alignment Verification
- Set up alignment equipment
- Measure angular offset
- Measure parallel offset
- Compare to tolerance
- Correct if needed
Decision Points
| Condition | Action |
|---|---|
| All within spec | Continue operation |
| Minor issues | Schedule correction |
| Major concerns | Plan replacement |
| Critical findings | Immediate action |
Extended Inspection (3-5 Years)
Comprehensive Overhaul
- Disassemble coupling completely
- Clean all components
- Measure tooth wear
- Check hub bore condition
- Inspect sleeve condition
- Evaluate seals
- Measure hardness (if concerns)
- Replace worn parts
- Reassemble with fresh grease
- Realign and document
Record Keeping Template
