Gears for Renewable Energy Applications
Precision gears for wind turbine pitch and yaw drives, solar trackers and hydro equipment, using premium materials with full-process inspection.
What to Send When Requesting a Quotation
Drawings are the starting point, along with the design life and, where available, the load spectrum. Inspection and flaw detection requirements should also be stated. Submissions go to sales@dgpinyi.com.
Materials and Heat Treatment Options
Main load-bearing gears are typically produced from 20CrMnTi with carburising and quenching. Case depth is measured to GB/T 9450 and held within 0.5~3.0mm. For large parts, quenched and tempered 42CrMo is an alternative. Magnetic particle and ultrasonic testing can be added to the inspection process according to project requirements; the exact items are confirmed at quotation.
Operating Conditions These Parts Face
Wind turbine pitch and yaw systems, solar trackers and hydro equipment all share a common trait: long design lives combined with service access that is difficult or costly. As a result, outgoing inspection is stricter than for conventional industrial parts.
- Tooth flank fatigue is the primary evaluation criterion, because alternating loads persist over design lives measured in years.
- Installation is often high up or in remote locations, so maintenance costs are significant and correct assembly on the first attempt is essential.
- Outdoor temperature swings are large, which places demands on both material selection and lubrication.
Gear Types and Size Ranges
- Spur gears / helical gears: Module, outer diameter and tolerance class as stated on the drawing
- Gear shafts / spline shafts: Maximum length ≤1000mm, shaft diameter tolerance h6/h7
- Precision racks: Module M1~M12, ground DIN 6h25
