The characteristics of helical gears are largely defined by their unique design: angled cuts at the edge of the gear. With their inherent qualities, they are capable of reducing friction, heat, and noise than other types of gears. Each of their teeth is perfectly intended to interlock with the teeth of the opposing gears that rotate in the opposite direction. The way their teeth interact with the gear axis rotation, crossed at a 90-degree angle or parallel, makes it more progressive and tempered than other gears.
Advantages of helical gears
The unique design properties of helical gears make them more advantageous to use. For instance, they are perfect for use for high load applications because of their increased number of teeth during rotation. Moreover, as they can transfer motion and power on right-angled and parallel axes, they can be used for many purposes.
These gears are also very durable because they can distribute loads evenly which also reduces wear over specific periods of time. Lastly, a helical gear operates more silently and steadily because the teeth are coming into contact only gradually, making the operation hassle-free.
Types of helical gears
Just like other gears available, helical gears are also made in different types and can be customized. One popular type is the single helical gear that is composed of a single row of miter teeth cut while the other type, which is the double-helical gear, is made of two rows of mirrored teeth. In terms of durability and resistance, it is the latter type that offers more benefits.
There are also some special types of double helical gears. These are the Chevron, form a letter V, and worm drives that have low loading capacities and are not ideal for high power transmissions.
So, if you are in the industry of transportation or manufacturing, the use of helical gear would be very advantageous due to the high speeds, lower noise, and smooth operation. You can ask us for further information about this gear and what type is best for your application.
