What Is A Double Helical Gear
Double Helical Gear - an overview | ScienceDirect Topics
The double-helical gear, also referred to as the herringbone gear (Figure 39.8), is used for transmitting power between parallel shafts. It was developed to overcome the disadvantage of the high-end thrust that is present with single-helical gears. Sign in to download full-size image Figure 39.8. More Information
What is a double helical gear? - Quora
Herringbone Gears or Double Helical Gears are an improved version of the Helical Gear. In a Helical Gear a resultant thrust is developed along the axis of the Gear and this has to be accommodated by having a thrust bearing. This reduces the efficiency of the system. More Information

Difference Between Single Helical Gear and Double Helical Gear
Such a helical gear arrangement is termed as double helical gear. Here, thrust force developed by each of the helical gears is opposite in direction but same in magnitude, and thus resultant thrust load becomes zero. More Information
A Guide to Double Helical and Herringbone Gears
A double helical gear can be identified if the pair of helical gears demonstrate opposite helix cuts on a gear blank with a narrow gap, allowing them to maintain the benefits of helical gears while also ensuring axial thrust loads are negated. More Information
The Different Types of Gears | Rexnord
Double helical gears are a variation of helical gears in which two helical faces are placed next to each other with a gap separating them. Each face has identical, but opposite, helix angles. Employing a double helical set of gears eliminates thrust loads and offers the possibility of even greater tooth overlap and smoother operation. More Information
Single vs. double helical gears SELECTION DEPENDS ON ...
The double helical gear eliminates internal thrust without introducing a thrust bearing, while maintaining a helical design for load sharing and smooth transfer of load from tooth to tooth. However, this style of gear is subject to a mismatch of the helices between the pinion and the gear. More Information
Difference Between Herringbone Gear and Double Helical Gear
In double helical gear, a small gap (2 – 10cm based on size) is maintained between left hand helix teeth and right hand helix teeth. Difficulty in manufacturing the gears: While cutting the gear teeth for herringbone gear, the cutter is not allowed to move beyond the teeth face in one side (where junction exists). More Information
What is a Helical Gear? (with picture) - InfoBloom
In a variation on the basic helical gear known as the double helical gear or herringbone gear, the gear has two sets of teeth side by side, slanting at different angles. This reduces the amount of thrust, eliminating the need to use specialized bearings. More Information
Helical gears: What are they and where are they used?
(The difference between the two designs is that double helical gears have a groove in the middle, between the teeth, whereas herringbone gears do not.) This arrangement cancels out the axial forces on each set of teeth, so larger helix angles can be used. It also eliminates the need for thrust bearings. More Information
Double helical gear advantages and disadvantages
A double helical gear is expensive as compared to helical gear. Balancing of thrust forces depends upon the equal distribution of load between the right and left parts of the gear. Therefore, a high degree of precision is required to locate double-helical gears axially on the shaft. No external forces are present. More Information
