What is backlash and why is it a problem?

Many components are spaced out to ensure that contact surfaces do not touch. This may be to allow for lubrication or thermal expansion, or it could be down to manufacturing tolerances or deflection under load. This spacing of components can cause backlash within the application.

Backlash occurs when a force is applied to a component as a result of the movement of another component. This can be seen in action when a train changes direction: the carriages shake and you hear clattering noises.

Even systems which are described as zero-backlash are likely to have a small amount of backlash. However, this is often so small that it doesn’t affect the application.

Precision applications such as robotics and servo applications need a high level of accuracy, so any lost motion caused by backlash is a problem.

Backlash is commonly associated with couplings. This is because backlash can accumulate in couplings as the joining piece for components. By selecting a backlash free coupling, the effects of backlash can be minimised within the system.

If you need assistance with minimising backlash in your application, contact our dedicated couplings division.

Back-lash free couplings FAQs

What is backlash free coupling?

Backlash-free couplings is a specialised coupling designed to eliminate backlash, ensuring smooth and precise motion control in various applications.

Why does backlash happen?

Backlash occurs when there are small gaps or clearances between the mating components in mechanical systems, such as gears or couplings. These gaps allow for slight movements when the direction of force changes, which leads to a delay in the system's response. 

This can happen because of manufacturing tolerances, wear and tear, or improper installation. At Acorn, our backlash-free couplings are designed to eliminate these gaps and ensure smooth, precise, and reliable operation of your machinery.

In which applications are backlash-free couplings typically used?

They are commonly used in servo motors, stepper motors, encoders, and positioning systems where precision and accuracy are essential.

What does zero backlash mean?

Zero backlash means that there is no play or clearance between mating components in a mechanical system. This means that when you apply force, it responds quickly and accurately without any gaps or slipping.
