What is Helical Gearbox?

A helical gear transmission includes a set of helical gears. A helical gear is a cylindrical gear with slanted tooth tracks. Compared to spur gears, they have higher contact levels, less vibration, excellent quietness and the ability to transmit larger loads. A set of helical gears have the same helix angle, but the helical hands are on opposite sides. Helical gearboxes are one of the most widely used and they are more efficient than any other gearbox. Their configuration is beneficial for many performances.

The Advantages of Helical Gearboxes

There are many benefits to using a helical gearbox. This type of gearbox is quieter than spur gears and can handle heavier loads than comparable gears. Its higher speed capability makes it ideal for applications such as conveyors, blowers, elevators, and the food and beverage industry. Double helical gears are another way to overcome some of the disadvantages of using a helical gearbox. But they are still less efficient than spur gears.

The two-stage helical gearbox is designed to minimize total power loss and bulk. The Pareto frontier is used to determine the minimum trade-off. Other design constraints include tribological requirements and hunting tooth frequency. These specifications were developed in accordance with the standards of the American Gear Manufacturers Association. In addition to these benefits, helical gearboxes are more efficient and save costs.
