What are WS Type Worm Gearboxes?

Worm gearboxes, a cornerstone of our rotary component range, embody the synergy between worm gears and worm drives to create a compact, high-torque output solution.

These components are marvels of engineering, designed to transfer motion at a 90-degree angle efficiently. The worm (a gear in the form of a screw) on the input shaft meshes with the worm wheel (a spur gear) of the output shaft, enabling a unique interaction that allows for significant reduction ratios in a minimal space.

This distinctive configuration makes worm gearboxes an essential component in various applications, ensuring smooth, reliable operation where precise control and torque are required.

How Worm Gearboxes Work.

The true beauty of worm gearboxes lies in their speed reduction and operational versatility. They are pivotal in scenarios demanding precise motion control and high torque output, such as in aerospace, robotics and heavy-load systems.

The compact worm drive gearbox's design allows for reduction ratios ranging from 10:1 to 50:1, making them ideal for applications where torque is paramount and space is at a premium. For instance, in the automation industry, the reduction gearbox can adjust the speed of robotic arms, ensuring precise, controlled movements. Their worm and wheel gearbox configuration translates into a mechanism where high reliability meets exceptional performance, embodying efficiency in motion transfer.

What Materials Worm Gearboxes Are Made From.

Accu's worm gearboxes are engineered for excellence, utilising high-grade materials to ensure durability and performance. The shell is crafted from robust aluminium, offering a lightweight yet sturdy housing that stands up to rigorous use. Inside, the gears are made from premium carbon steel, chosen for its toughness and resistance to wear.

This material selection ensures that each worm gear gearbox operates flawlessly in various environments, from clean, controlled manufacturing floors to more demanding industrial applications, enhancing the worm gearbox's efficiency and longevity.

What Size and Type Worm Gearboxes Are Available.

Our worm gearboxes cater to a wide range of engineering projects, with the smallest shaft diameter starting at 5mm and the largest at 8mm. This range, combined with worm gearbox ratios from 10:1 to 50:1, allows for precise customisation to match specific requirements. Our product line includes worm screw gearbox options designed for right-angle motion transfer, making them perfect for use with shaft couplings.


Q: What does a worm gear box do?.

A: A worm gearbox reduces rotational high-speed input and increases torque in machinery, allowing for precise control and motion at right angles from the input shaft to the output.

Q: What are the disadvantages of worm gearboxes?.

A: While worm gearboxes are highly efficient in reducing speed and increasing torque, they can exhibit lower efficiency compared to other gearbox types due to friction and heat. However, these issues can be minimised with proper material selection and project design.

Q: How are Accu's worm gearboxes installed?.

A: Accu's worm gearboxes are designed for straightforward installation. They can be mounted using cap head screws via the counterbored mounting points, ensuring a secure and efficient setup. These fixing points can also be tapped with their own threads to facilitate a lightweight installation.

Q: What does WS type mean?.

A: The WS type is an identifier for Accu's worm-type gearboxes. This designation helps distinguish them from other types, such as the BS type bevel gearboxes, ensuring that customers find the exact gearbox to meet their needs.
