Understanding Torque and Torque Testing

Torque, also known as 'moment of force' in mechanical engineering, refers to the angular force necessary to rotate an object. It is easiest to imagine a force as a simple push or pull, with torque being a twisting force acting upon an object. Torque has many everyday applications, although the most commonly seen are in mechanical fastenings, and on smaller individual scales such as parts of engines, transmissions, or motors.

Torque testing itself involves establishing and measuring the total amount of force an object is exposed to. Whatever the application, rigorous torque testing is essential to ensure the quality of individual parts and larger mechanisms, and can be used to identify process-wide defects with serious implications.

How Do You Measure Torque?

Most testing involves the use of a tool called a torque transducer or sensor. The device is finely inserted between the applied force and object to be tested, allowing a detailed torque measurement to be taken. There are two main approaches to torque testing and calibration. The in-line testing technique offers a more conventional measurement of the torque needed to turn a rotating component, while reaction testing instead focuses on the amount of force needed to prevent a part from spinning.

Largescale Torque Testing and Applications

Today, large industry is reliant upon torque testing. Complex machinery and large products can require thousands of individual parts and components, with potentially millions of bolts and screws tightened by some kind of torque driver or other. Regular testing of largescale machinery and equipment is essential to ensure no single fastener is compromised.

It only requires the failure of one fastener to affect the structural integrity of larger components and products, making it crucial that manufacturers deploy rigorous testing and inspection to ensure each and every fastener is properly tightened, and showing zero signs of weakness or structural integrity.

It's relatively straightforward to ensure fasteners are tightened to maximum torque, but monitoring weaknesses and establishing pre-existing issues can be a much trickier affair. Torque testing can identify progressive problems, as well as establish issues that might have been around since installation.

Torque-to-Turn Tests

Torque-to-turn measurements are a crucial way to diagnose and determine problems for large-scale manufacturing, assembly lines, and any industry depending on machinery involving rotary parts, transmissions, motors etc. Basic torque-to-turn testing falls into two broad categories; breakaway torque testing, and running torque testing.

Breakaway torque is the measurement of how much torque it takes to get a component going with enough force to tart rotary motion from standing. This is obviously a pivotal part of any process, but can often be compromised due to commonplace problems like out-of-date parts and fixtures, poor maintenance, stresses in construction, and even lack of service oil.

Testing breakaway torque is a good indicator of the overall health of the larger parts, and a good way to determine integrity of machinery quickly. Runaway torque testing quantifies how much torque is needed to sustain the movement of things and keep rotating parts in motion. Simply measuring the average torque can indicate and help diagnose the root cause of larger issues.

Torque Testing - Essential Quality Assurance

For total peace of mind and the rigorous compliance to safety standards, regular testing of manufacturing equipment and assembly line machinery is crucial for any growing business. Torque testing is a key part of inspection and maintenance of structures to ensure quality and prevent any potential safety issues. Of course, inspections should be carried out regularly however it is understandable that for some buildings and structures accessing awkward areas can be difficult.
