Engineering & Manufacturing Capability
We bridge the gap between engineering blueprints and reliable transmission performance. Whether you need prototype development, replacement parts, or volume OEM manufacturing, our technical team provides complete DFM optimization and precision machining.
How ZhongYi addresses the root causes of premature gear failure, excessive backlash, and operational wear in the field:
Utility-scale solar farms in remote deserts and offshore wind installations demand extreme reliability. Unexpected gear failure or premature wear leads to massive maintenance costs and lost power generation.
Turbulent wind storms create sudden holding torque peaks and reversing dynamic loads on solar tracker slewing drives and wind turbine yaw/pitch gears. Teeth must resist catastrophic shear fracture.
Continuous exposure to desert UV radiation, blowing sand abrasives, coastal marine salt spray (C5-M environment), and extreme temperature shifts (-40Ā°C to +60Ā°C) causes rapid seal failure and corrosion.
Solar tracking efficiency depends on holding precise PV panel angles against wind buffeting. Slewing worm drives require tight backlash control without binding over decades of operation.
20-Year Outdoor Service
Optimized metallurgical alloys, deep carburizing, and C4/C5 marine-grade protective coatings for extreme outdoor longevity.
Up to 50,000+ NĀ·m Rated Torque
Heavy alloy steel forging and tooth induction hardening engineered to withstand hurricane-force wind gust holding moments.
DIN 6 / AGMA 10-12
Enveloping and cylindrical worm gear pairs with precision CNC thread grinding and high-load phosphor bronze wheel hubs.
Charpy V-Notch at -40Ā°C
Vacuum-degassed 18CrNiMo7-6 and 42CrMo4 steel tested for high impact fracture toughness in cold-climate wind farms.

Tier-1 Utility-Scale Solar PV Tracking System Integrator (Company E)
20-Year Longevity
Withstands 160 km/h Desert Wind-Gust Shocks
The customer experienced excessive backlash increase and tooth surface galling on solar tracker azimuth worm drives during extreme desert windstorms (wind gusts exceeding 130 km/h), causing tracker position errors and lost solar generation.
ZhongYi developed an optimized hour-glass / enveloping worm gear set combining a deep-carburized 42CrMo4 worm shaft (59ā62 HRC, ground Ra 0.3 Āµm) with centrifugally cast high-strength nickel phosphor bronze (CuSn12Ni2) worm wheel. We applied lead crowning to distribute wind shock torque and added C5-M anti-corrosion sealed housing interfaces.
Withstood simulated 160 km/h gale-force wind-tunnel shock load tests with zero tooth deformation
Maintained verified backlash under 0.08Ā° over 30,000 continuous full-rotation tracking cycles
Certified for 20-year maintenance-free outdoor service in harsh desert environments
Enabled customer to secure utility-scale 500MW+ solar farm bids with a 10-year mechanical warranty
Technical FAQ
Clear answers to common engineering, metallurgical, tolerance, and procurement questions for international OEM machinery buyers.
Our solar tracker worm sets use an optimized contact ratio and high-strength centrifugally cast phosphor bronze (CuSn12Ni2) mated with carburized alloy steel (42CrMo4, 60 HRC). The optimized tooth crowning spreads high wind holding moments across multiple teeth simultaneously, preventing tooth shear even under 150+ km/h wind gust shocks.
We manufacture pitch and yaw gears from premium vacuum-degassed 18CrNiMo7-6 or 42CrMo4 forgings per DIN / ISO standards. Teeth are carburized or induction hardened with deep case depth (1.8ā2.5 mm) and 100% NDT (UT and MPI) inspected with Charpy impact testing certified at -40Ā°C.
