When you seeking smooth and durable helical gear solutions for your high-speed, heavy-duty transmission systems, our products deliver core values of high-efficiency transmission, ultra-quiet operation, and exceptional torque capacity, specifically engineered for premium applications such as automotive transmissions, aerospace equipment, industrial robots, and wind turbine gearboxes. Addressing industry challenges like excessive noise, significant axial vibration, and fatigue fractures under high-speed conditions, we offer three innovative solutions: carburized 20CrNiMo alloy helical gears (optimized 30° helix angle design, 40% increased contact ratio), high-strength nylon composite helical gears (self-lubricating, impact-resistant, ≤50dB noise), and titanium alloy lightweight helical gears (3x higher specific strength than steel). Leveraging 5-axis CNC grinding processes (ISO Class 5 precision) and modified helix angle correction technology, we achieve ≥99.5% transmission efficiency with precise axial thrust control. Validated by rigorous data: 12dB noise reduction in NEV reducers, GL-certified 20,000-hour maintenance-free operation in wind turbine gearboxes, and robotic joint transmission backlash <1 arc-minute. Let our cutting-edge helical gears empower your systems with silent strength and relentless reliability.
