Herringbone gears, also known as double helical gears, are gear sets designed to transmit power through parallel axes or (less commonly) vertical axes. The unique tooth structure of herringbone gears consists of two adjacent opposing spirals in the shape of the letter "V".
Herringbone gears mate by using smooth, precisely manufactured V-shaped teeth. Like helical gears, multiple teeth mesh during rotation, spreading the workload and providing quiet operation. However, due to their tooth structure, herringbone gears counteract the axial thrust typical of helical gears.
The double helical design helps cancel out axial thrust forces, resulting in smoother operation and reduced noise compared to single helical gears. This is particularly beneficial in applications where noise and vibration are critical considerations.
The herringbone design distributes the load more evenly across the gear teeth. This results in better load-carrying capacity and enhanced durability, making them suitable for high-torque and heavy-duty applications.
The improved load distribution and reduced axial thrust contribute to higher efficiency in power transmission. Herringbone gears are known for their efficiency and reliability, especially in situations where precise and consistent motion is essential.
The concave and convex shape of the gear teeth in herringbone gears creates a natural channel for lubricant flow. This design promotes better lubrication and heat dissipation, leading to lower wear and longer gear life.
The double helical structure allows herringbone gears to handle bidirectional loads effectively. They are suitable for applications where the direction of rotation may change frequently without causing issues such as gear kickback.
The herringbone design helps cancel out axial thrust forces, which can be a common issue in single helical gears. This is particularly important in applications where axial forces need to be minimized to prevent damage to bearings and other components.
In precision machine tools, such as lathes and milling machines, herringbone gears are used to transfer power between motors and moving parts. This helps ensure precise machining and reduces unnecessary vibrations.
Whether in the energy sector or in industrial applications, turbines use herringbone gears to optimize power transmission. Vibration and noise reduction are particularly beneficial in high-speed applications.
In gear transmission systems, such as transmissions, herringbone gears are used to reduce rotational speed and increase torque. This improves system efficiency and stability.
Herringbone gears are used in mining and quarrying equipment and machinery, such as mills and crushers. Their ability to handle high loads and reduce vibration is critical in these demanding applications.
In the marine industry, herringbone gears are used in applications such as ship transmissions, ship propulsion systems and offshore wind turbines.
