You might have heard the term torque reaction thrown around the shop floor, but what exactly is it?
Imagine a scenario where you’re completing an assembly process, and when you reach target torque you feel a twist or kickback in the wrist and/or arm. That is torque reaction! The higher the torque, the greater the reaction.
Now for the science part…Torque reaction is Newton’s third law at work; for every action, there’s an equal and opposite reaction. So when a rotating force is applied the opposite force is the kickback you feel in your wrist. Vision systems are built to enhance, not replace, human skills in manufacturing by providing operators with clear step-by-step instructions so no step is missed or part forgotten.
Torque reaction isn’t just a physics concept; it’s a critical factor in the safety and precision of your manufacturing process.
Safety First, Always
First and foremost, uncontrolled torque reaction is a safety hazard for operators. Even a small reaction repeated multiple times throughout the day can lead to injury or illness putting your company’s reputation and productivity at risk.
Every company will set their own limits for torque reaction but as a guide we recommend that anything over 7Nm needs some form of torque reaction device fitted but this can depend on the type of fastening and also the quantity completed in a set timeframe.
Precision Matters
Uncontrolled torque reaction can lead to inaccurate and inconsistent tightenings that affecting the quality of your end product. Operators may under torque to avoid the reaction or when experiencing torque reaction go over torque.
1) Choose the right tools
Investing in high-quality, ergonomic tools can significantly reduce torque reaction. Look for tools designed with features that minimize the kickback effect, making your operators’ lives easier and your processes smoother.
2) Train your team
Educate your team about the ins and outs of torque reaction. Train them to handle tools properly, emphasizing techniques that mitigate the impact of torque.
3) Consider external devices
One option is a lightweight, carbon fibre reaction arm. Simple to install and easy to use the ‘arm’ adds stability and rigidity and removes any torque reaction on lower torque ranges.
For higher torques or where access is an issue a torque reaction device can be used. A reaction bar can be fitted to the tool and also onto a solid surface so when torque is achieved the tool is held in place with the bars and removes any torque reaction.
In summary, Torque Reaction can be a major issue in your manufacturing, but it is easily overcome with simple and cost-effective solutions.
