Herringbone Gears: Characteristics and Applications

Mar. 18, 2024 Share:

Herringbone gears, also known as double helix or double helical gears, are a specific type of spur gear characterized by teeth arranged in a "V" shaped profile. They find extensive applications across various industries due to their unique design.


What are herringbone gears?


Herringbone gears are distinguished by their teeth arranged in a "V" shape, with helixes wound in opposing directions. This arrangement provides a distinct appearance and enables smoother power transmission compared to conventional gears. The double helix structure of herringbone gears offers notable advantages, including enhanced load capacity and minimized vibration and noise.

Advantages of herringbone gears


Herringbone gears provide numerous benefits compared to other gear types. Their double helix configuration effectively balances axial thrust forces, thereby decreasing wear and enhancing the efficiency of both bearings and gears. This renders herringbone gears optimal for applications demanding dependable, silent, and high-performance power transmission.


Fields of application


Herringbone gears find wide applications in different industries. Some examples include:


Machine tools: In precision machine tools, such as lathes and milling machines, herringbone gears are used to transmit power between motors and moving parts. This helps ensure accurate machining and reduces unwanted vibration.


Turbines: Herringbone gears are utilized in turbines, both within the energy sector and industrial settings, to optimize power transmission. Their capacity for reducing vibration and noise proves especially advantageous in high-speed applications.


Gearbox: Within gear drive systems like gearboxes, herringbone gears are employed to lower rotational speed and boost torque, thereby enhancing system efficiency and stability.


Mining and quarrying: Herringbone gears are employed in machinery used for mining and quarrying, including mills and crushers. Their capability to manage heavy loads and minimize vibration is essential in these rigorous operations.


Marine industry: Within the marine sector, herringbone gears find applications in marine transmissions, propulsion systems, and offshore wind turbines.


Construction Challenges


The design and construction of herringbone gears can pose several challenges compared to traditional spur gears or single helix gears. Some of the major challenges include:


Axial Alignment: Achieving precise axial alignment is crucial for herringbone gears to ensure proper meshing of the teeth. Even a slight deviation can result in tooth collapse and reduced gear lifespan.


Special Machining: The complex shape of herringbone teeth makes machining more intricate than with spur gears. Specialized machines and equipment are necessary to achieve the correct tooth geometries and ensure high gear quality.


Tolerances and Accuracy: Given the complex interaction between herringbone teeth, strict attention to tolerances and accuracy during design and construction is essential. Variations in tooth sizes or angles can impact proper meshing and gear longevity.


Manufacturing Costs: Construction complexities and special machining requirements make herringbone gears generally more expensive to produce than spur gears. Nevertheless, the performance and reliability benefits often outweigh the investment.
