Helical gears are also known as Dry Fixed gears. They are considered as the refined version of spur gears. These gears are built with the leading edges of the teeth are not parallel to the axis of rotation, instead, they are set at an angle. Since this type of gear is curved, this angling makes the tooth shape a segment of a helix. These gears can be meshed in parallel or crossed orientation.
In this article, you will so much about helical gears. From the advantages that they offer all the way to the most common applications that these gears are used. This article will give a complete overview about helical gears.
Various Advantages of Helical Gears
- The design of a helical gear allows it to provide a silent and smoother operation compared to spur gears.
- These gears are built and designed to handle heavy load applications. Making them ideal for heavy-duty equipment.
- Helical gears are also capable of transmitting the power and motion between two parallel shafts as well as between two non-parallel shafts.
- They offer more capability in transmitting load between two parallel shafts compared to a similar module and equivalent width of spur gears.
- Helical gears are more resistant to wear and tear compared to spur gears because the load on helical gears are distributed to several teeth.
Helical gears are normally used in applications that involve heavy loads. They are normally preferred to work under heavy load efficiency. They are also used for silent operations such as automobile applications. Other areas of applications of these gears include:
● Fertilizer industries, printing industries, and earth moving industries
● Steel industries, rolling mills, section rolling mills, power and port industries
● Textile industries, plastic industries, food industries
○ Conveyors
○ Elevators
○ Compressors
○ Blowers
○ Cutters
Now, with this information, you have the proper knowledge when it comes to helical gears. These small components are vital to various industries and applications.
