Double Helical Gears

Double helical gears, or herringbone gears, overcome the problem of axial thrust presented by “single” helical gears, by having two sets of teeth that are set in a V shape. A double helical gear can be thought of as two mirrored helical gears joined together. This arrangement cancels out the net axial thrust, since each half of the gear thrusts in the opposite direction. However, double helical gears are more difficult to manufacture due to their more complicated shape.

High-Performance Double Helical and Herringbone Gears

RMT Tools is proud to produce quality parts to meet the stresses and demands of mechanical drives. Double helical gears are widely used because their design and operating features offer additional benefits.

What are Double Helical Gears?

Double helical gears, also known as double helical and herringbone gears, in which there are two separate sets of helical teeth. These sets of teeth are cut at an angle, and two cutting teeth are in opposition to each other so that they engage simultaneously. The result is reduced noise and vibration compared to single helical gears. It brings about a smoother, more effective operation.

Key Features

1. Higher Load Capacity: A double helical design increases the contact area, permitting the capability of carrying higher loads. They are applicable for heavy loads with high strength and durability.

2. Low Noise and Vibration: Impact forces and their resulting noise are reduced by engagement with the two sets of teeth. This is helpful in applications where working noise is essential and requires a low noise signature.

3. Improved performance: The teeth are helically placed so that the double helical gears transmit power more smoothly and reliably, resulting in a better performance of the intended mechanical system.

Description Double Helical Gear Angle

This means that the teeth are cut at a double helical gear angle. This is critical because it can mean the difference between a well-performing gear or not. Some of the parameters it affects are load sharing and efficiency, to name a few. Creating the proper gear angle can optimize it for particular applications that will bring better general system efficiency.

Common Uses of Double Helical Gears

Double helical gears are so popular due to their versatility in almost any working environment. Applications for double helical gears include heavy industrial machines, gearboxes, and drives that require reliability and strength.

Automotive Systems: When double helical gears are applied to automobile transmissions, noise becomes less while changing gears, resulting in a smoother drive.

Aerospace Applications: The gears’ high precision and load capacity make them appropriate for use in aerospace applications, where performance and reliability are crucial for gear systems.
