A Perfect Guide on Choosing the Perfect Right Angle Gearbox

An industrial right-angle gearbox is a vital component in many heavy-duty industries that rely on mechanical power transmission. Due to its compact size and high torque capacity, it is used in multiple applications like conveyor belts, mixers, agitators, and cranes. The reason why right-angle gearboxes are preferred over other types of gearboxes is it that it offers a cost-effective solution for power management and gives a performance output even in restricted spaces.

Understanding Right Angle Gearboxes

A right-angle gearbox is a type of gearbox wherein the input and output shaft meet a 90-degree angle. It allows torque to be transmitted from one axis to a perpendicular axis and uses rotation to transfer power.

There Are 4 Main Types Of 90-degree Gearbox

Worm Gearbox: Worm gearboxes are a type of gear system where higher torque is achieved at a low-speed gear ratio. Being simple and compact in design, they can achieve a higher gear ratio than helical gears.

Bevel Gearbox: A bevel gearbox transmits, splits or distributes the power of a single rotating drive shaft through a detailed angle which is generally 90 degrees. The name bevel gearbox is derived from the gear design that is used inside the gearbox. The gearboxes are a single-stage unit supplied with gear ratios ranging from 1:1 to 4:1.

Hypoid Gearbox: A hypoid gearbox is a unique type of precision gearbox where the axes intersect on two parallel planes. As compared to other bevel gearboxes, there is no axis offset and both the input and output shaft can rotate in the same as well as opposite direction

Spiral Bevel Gearboxes: Spiral bevel gears basically bevel gears but with the helical teeth positioned at a 90-degree angle. The teeth are designed with a slight curve for better flexibility and traction. Although they are hypoid gears, they have no offsets which means that they will not slip while in operation. That is why, they are preferred for high-speed and torque applications.

How To Choose the Perfect Right Angle Gearbox

1. Load And Torque Requirements

It is important that you clearly communicate with your vendor about the strength and size of the drive needed for specific applications. It is a common scenario wherein customers underestimate the amount of torque a drive will need on the job and later discover that the teeth are wearing off, bearings are failing, and pins are shearing. This is because each drive is rated for an ultimate static torque. That is why, it is important that you know your load and torque requirements.

2. Environmental Factors

To ensure your right-angle gearbox can support your application, you’ll also need to take into consideration the environment that it is in. Some environmental conditions may require special materials like corrosion-resistant paints and stainless-steel housing as harsh environments can accelerate the wear and tear of your unit.

3. Load Type

While choosing a right-angle gearbox, consider the type of load of your application which could be either a uniform load, non-non-uniform, or impact load. A uniform load remains constant during operation and continuously moves products. For e.g., a food or beverage processing conveyor belt. A non-uniform load changes during operation and requires a higher service factor as intermittent forces can cause a cyclical increase in your gearbox torque. With a high-impact load, you’ll want to consider the wear on the right-angle gearbox gear, shaft bearings and increased service factor.

Selecting the perfect right-angle gearbox requires a thorough understanding of your application’s needs, careful evaluation of technical specifications, and consideration of installation, maintenance, and cost factors. By following these guidelines, you can ensure that you choose a gearbox that meets your requirements and delivers reliable performance.
