How to Select the Perfect Gearbox for Your Application
Choosing the right gearbox is crucial for optimal performance and longevity of your industrial equipment. At Tau Engineers, Ahmedabad, we've helped hundreds of clients across Mumbai, Delhi, Chennai, Bangalore and other Indian cities select the perfect gearbox solution.
Key Factors in Gearbox Selection
1. Determine Your Torque Requirements
Torque is the most critical factor in gearbox selection. Calculate using:
Torque (Nm) = (Power (kW) × 9550) / Speed (RPM)
- Always select a gearbox with 20-30% higher torque capacity than your calculated requirement
- Consider peak torque during startup
2. Understand Speed Reduction Needs
The gear ratio determines output speed:
- High ratio (20:1 to 100:1): Worm gearboxes
- Medium ratio (3:1 to 20:1): Helical gearboxes
- Precision ratios: Planetary gearboxes

3. Consider Operational Environment
- Dusty conditions: Sealed gearboxes with IP65 rating
- High temperatures: Special lubricants and cooling fins
- Corrosive environments: Stainless steel construction
Gearbox Type Comparison
| Type | Best For | Efficiency | Noise Level | Maintenance |
|---|---|---|---|---|
| Worm Gearbox | High ratio, low speed | 60-90% | Moderate | Low |
| Helical Gearbox | Medium ratio, high torque | 94-98% | Low | Medium |
| Planetary Gearbox | Precision, compact spaces | 97-99% | Very Low | High |
| Cycloidal Gearbox | Shock loads, heavy duty | 80-90% | Moderate | Medium |
Common Selection Mistakes to Avoid
1. Underestimating Service Factor
Always consider:
- Number of starts/stops per hour
- Shock loads in application
- Duty cycle (continuous vs intermittent)
2. Ignoring Mounting Requirements
Consider:
- Foot-mounted vs flange-mounted
- Shaft orientation (horizontal/vertical)
- Available space constraints
Pro Tip: For applications in cement plants, steel mills, or heavy industries, always opt for oversized bearings and special hardened gears to handle extreme conditions.
