High-Performance Gear Solutions for the Automotive & Motorcycle Industry

Industry Challenges: Power Density & NVH Control

Automotive and motorcycle components are facing higher power density and stricter NVH (noise, vibration, harshness) requirements. Whether for engines and transmissions, steering, oil pumps, water pumps, starter systems, or in-cabin mechanisms, gears must maintain consistent accuracy under high speed, repeated loading, and long operating hours—without risks of accelerated wear, abnormal noise, or efficiency degradation. OEMs need a custom gear manufacturer capable of meeting these rigorous standards.

Shyi Chang’s Advantageous Solutions

As a specialized spur gear supplier and bevel gear manufacturer, Shyi Chang addresses these challenges through:

• Durability and reliability under high torque
  To address fatigue and wear challenges in driveline and pump gears, Shyi Chang plans material selection and heat-treatment conditions to increase tooth-surface strength and wear resistance, ensuring stable performance over long service cycles.
  
• NVH control and smooth operation
  By managing gear profile accuracy and tooth-surface quality, we reduce meshing noise and vibration, improving overall vehicle comfort.
  
• Consistency and traceability for mass production
  With process control and inspection workflows, we ensure batch stability and help customers reduce assembly variation and after-sales risks.
