1)Descriptions of Double Helical Gear

Double helical gears are an efficient transmission component that combines the smoothness of helical gears

with the mechanical advantages of herringbone gears.

They are widely used in the heavy industry sector.

2)Features of Double Helical Gear

  • The transmission process is continuous and smooth, with lower vibration and noise compared to spur gears, approaching the performance of herringbone gears.
  • Suitable for high-speed and heavy-load applications, such as turbine machinery, large reducers and ship propulsion systems.

3)Advantages of Double Helical Gear

  • Smooth and quiet operation: Helical gears reduce impact, making them particularly suitable for applications that are sensitive to noise.
  • High reliability and long service life: The symmetrical tooth design reduces uneven load wear, thereby extending the service life of gears and bearings.
