Helical gear characteristics

Helical gears are defined by their unique design with angled cuts at the edge of the gear. They reduce friction, heat, and noise exceptionally well compared to other types of gear. Each gear tooth is designed to interlock with the teeth of the opposing helical gear, which rotates in the opposite direction.

Helical gears work like any other gear that rotates via interlocking teeth, but they are more tempered and progressive than different types. This is mainly due to how their teeth interact with the axis rotation, which can be parallel or crossed at a 90-degree angle.

Advantages of helical gears

The manufacturing of helical gears gives them unique properties, often seen as advantages.

For example, these gears are ideal for high load applications due to the increased number of teeth in contact during motion. They also have many uses since they can transfer movement and power on parallel and right-angled axes.

Helical gears are also known for their durability since they distribute the load evenly over the axles, reducing wear over time.

Finally, their inclined teeth gradually come into contact, making them much quieter and promoting steady, hassle-free operation.

Types of helical gears

When it comes to gear manufacturing, single and double helical gears can be custom-made. Single helical gears consist of a single row of miter teeth cut or inserted on the gear body perimeter, while double-helical gears consist of two rows of mirrored miter teeth. The advantages of double-helical gears over single ones are increased resistance and durability and the elimination of axial loading.

Applications of Helical Gears

Helical gears transfer heavy loads at a very high speed between parallel shafts. Here are the Applications of helical gears in various products.
