Motor Greasing Fundamentals
Importance of Greasing
Proper motor greasing is crucial for:
- Reducing friction and wear
- Dissipating heat
- Preventing corrosion
- Extending bearing and motor lifespan
Factors Affecting Greasing
- Motor speed (RPM)
- Operating temperature
- Bearing type and size
- Environmental conditions
Key Considerations:
Over-greasing can be as harmful as under-greasing, leading to overheating and seal damage.
Always use compatible grease types when mixing or changing lubricants.
Calculation Formulas (Simplified)
Grease Quantity (grams):
G = ((HP × 0.4) + (RPM / 1000 × 0.1)) × Bearing Factor
Greasing Frequency (days):
F = 365 / (1 + (RPM / 2000) + (Temp / 20))
Example Calculation
For a 50 HP motor, 1800 RPM, Ball Bearing, 40°C:
HP: 50
RPM: 1800
Bearing Type: Ball
Temp: 40°C
Grease Quantity = ((50 × 0.4) + (1800 / 1000 × 0.1)) × 1 = (20 + 0.18) × 1 = 20.18 grams
Greasing Frequency = 365 / (1 + (1800 / 2000) + (40 / 20)) = 365 / (1 + 0.9 + 2) = 365 / 3.9 = 93.59 days
Result: Grease Quantity = 20.18 grams | Greasing Frequency = 93.59 days
