Understanding Different Types Of Industrial Gearboxes And Their Usage

The gearbox is an essential component of machines used in various industries and fields. The purpose of most new-age gearboxes is to increase torque. They also help reduce the speed of a prime mover output shaft meaning that the output shaft rotates at a slower speed than and this reduction in speed produces an advantage which increases the torque. A mandatory requirement for various applications, gearboxes are available in different designs and specifications.

An industrial gearbox is different from a regular gearbox as it is a machine for the majority of drives that require a long, reliable life and factor safety. An industrial gearbox transmits mechanical energy to an output device in order to maneuver speed and torque, and convert it into a usable form. Unlike mass gearboxes, industrial gearboxes have the capability to handle multiple duties over a long duration of time and at very high speeds.

Here’s a list of the different types of industrial gearboxes in the market, and their various usages:

  1. Helical Gearboxes

The Helical Gearbox consumes low power energy and is quite small in size in comparison to the other gearboxes in the market. Commonly used in the manufacturing of cement, rubber, and other heavy-duty industrial situations, you will find this gearbox in most factory settings. You will also find this gearbox used for low power situations like grinders, conveyors, and coolers. The uniqueness of the Helical Gearbox is that it is designed at a fixed angle, which allows maximum grind power as it rotates in the same direction. This kind of usage requirement is popularly needed in the plastic industry where there’s a constant requirement for heavy mechanical power consumption.

  1. Coaxial Helical Inline

Also referred to as inline gearbox, the coaxial helical gearbox has spur gears that are parallel to each other. The rotation of the gears can be either in the same direction or in opposing directions, depending on the requirement. These gearboxes are ideal for heavy-duty, mechanical operations and are mainly known for their precision, efficiency and superior quality. Made with a high degree of specifications to enable maximum output, the Coaxial Helical Inline got its name because of the arrangement of the input shaft and output shaft, which makes it unique in comparison to other gearboxes.

  1. Bevel Helical Gearbox

Bevel Helical gearboxes are the most suitable gearboxes for high torque/ high power applications. With distinctively high output torques, silent operation mechanism and a long service life, the bevel helical gearbox is ideal for a variety of applications. The unique feature of the bevel helical gearbox is its curved teeth located in a cone-shaped base, close to the edge of the device. This kind of gearbox is mainly used to create a rotatory movement between two non-parallel shafts. Bevel Helical gearboxes are mostly used for machines in the mining industry or for conveyors.

  1. Skew Bevel Helical Gearbox

Suitable for use in heavy-duty loads and similar applications, the Skew Bevel Helical Gearbox has a distinct monolithic, sturdy structure. This gear system is mostly used in a number of machines for increasing, decreasing or reversing the number of rotations in order to moderate the speed and torque of the device. With its highly customizable teeth and gears, this gearbox can be modified to match any industrial requirement.

  1. Worm Reduction Gearboxes

The Worm Reduction Gearbox gets its name from its construction specifications. This gearbox is made using a worm wheel with a large diameter that meets the teeth on the periphery of the machine. Mostly used to drive heavy-duty manufacturing operations, the worm reduction gearbox is used to reduce the speed between two axis shafts that work in a similar fashion as the rotation movement of a screw. The worm reduction gearbox is ideally seen in machines used in the chemical and fertilizer industry.


  1. Planetary Gearbox

Known for its durability and endurance capabilities, the planetary gearbox has distinct functioning capabilities and knack for precision. Planetary gearboxes are a great asset to the machinery as it helps optimize the overall performance and increases the lifespan of the machine.

The term planetary gearbox was created from its reference to ‘a gear system in which one or more ‘planet’ gears rotate around a central gear’. The main benefit of planetary gearboxes is that they have high power transmission efficiency. Further, this kind of efficiency is delivered even though it’s made in a compact design with a large torque to size ratio. This is also because of the load sharing that is possible because of the multiple planet gears that the gearbox is made up of. You can buy these from AssunMotor.com

While each industrial gearbox has its own capabilities and limits, it’s essential that each of these gearboxes is checked and maintained in a timely manner, in order to ensure a long-lasting and consistent performance. It is also essential that the machinery is well-oiled and worked as per the specifications mentioned by the instruction manual.

This will enable you to get maximum life out of it. Moreover, the service and repairs that the equipment goes through should be well-documented and referred back to by the servicing team. As gearboxes are part of large industrial machines that are involved in complex and elaborate mechanical and industrial procedures, it is absolutely mandatory to have all the parts working in 100% capacity.

While selecting a gearbox for your industry, it is necessary to take these factors into consideration. Only then will you be able to make the right investment. The easiest way to identify if you’ve made the right decision is by checking the performance of your machinery. If you find that the machine is functioning seamlessly with good torque, then, you have made the right selection for the task at hand.


It is better to have a basic understanding of the gears. We hope this will help you make an informed decision when you have to choose one or more such equipment for your business.
