Brief: See the journey from feature description to real application in this concise overview. This video demonstrates how double helical gears deliver smooth power transmission in heavy-duty industrial machinery, showcasing their unique design that balances axial forces and enables high torque handling.
Related Product Features:
  • Symmetrical V-shaped tooth profile with opposing helix angles that self-balance axial forces.
  • Eliminates the need for additional axial positioning structures, reducing bearing loads.
  • High load-carrying capacity with 40%-60% larger tooth contact area than equivalent spur gears.
  • Transmits exceptionally high torque, suitable for thousands to tens of thousands of Newton metres.
  • Superior transmission smoothness with progressive engagement and minimal impact.
  • Low vibration and operational noise levels 10-15dB lower than spur gears.
  • Excellent structural rigidity with symmetrical design reducing gear deformation.
  • Adapts to prolonged heavy-duty operation in demanding industrial applications.
FAQs:
  • What are the main advantages of double helical gears over single helical or spur gears?
    Double helical gears offer self-balancing axial forces, higher load capacity with 40%-60% larger contact area than spur gears, superior smoothness with lower noise (10-15dB reduction), and excellent structural rigidity for heavy-duty applications.
  • In which industrial applications are double helical gears typically used?
    They are ideal for heavy-duty equipment requiring high torque transmission and smooth operation, including large rolling mills, mining crushers, marine main engine gearboxes, large generator sets, heavy construction machinery, and cement rotary kilns.
  • What manufacturing processes and quality standards are used for these gears?
    Our double helical gears are manufactured using gear milling and hobbing processes with teeth grinding, heat treated through carburizing/cement quenching, and achieve high accuracy grades of ISO 6 or AGMA 11 for reliable performance.
