Sun Gears for Renewable Energy Drives
Planetary stages in renewable-energy equipment can combine long service expectations with variable torque. The RFQ should state life and duty rather than only nominal power.

Application-specific RFQ checklist
| Parameter | What to Specify |
|---|---|
| Duty data | Torque spectrum, speed, cycles, target service life and temperature range. |
| Geometry | Planetary tooth relationship and load-sharing assumptions. |
| Interface | Spline or shaft connection, bearing seats, lubrication path and assembly datum. |
| Risk point | Long service expectations increase the importance of tooth contact and documented inspection. |
Confirm the whole planetary interface
Energy applications often make fatigue life, contact pattern, material condition and documented inspection more important than a simple nominal torque comparison.
Where design data are incomplete, provide the complete tooth-count set, number of planets, operating speed range and any existing inspection or material records from the original assembly.
