How to do a Torque Test?
Torque testing usually involves multiple test items. Ensure a comprehensive evaluation of product quality and performance. Common inspection items include:
Fastener torque test:
Used to detect the tightening force and looseness of bolts, nuts and other fasteners in different environments.
Rotating parts torque test:
Evaluate the torque transmission efficiency of motors, transmissions and other rotating devices in operation.
Tool torque calibration:
Calibrate torque tools. such as torque wrenches and screwdrivers to ensure the accuracy of their output.
Connector torque test:
Check the sealing and durability of pipes, pipe fittings and other connectors.
How to Calculate Residual Torque?
Residual torque is the torque required to move the tightened thread relative to the mating thread. When the tightening assembly is completed, the bolt will rotate again after being tightened. There will be a significant change in the slope, and the torque value obtained at this time is the residual torque.
Breakaway method:
When we further tighten the already tightened bolt, a breakaway torque will be generated. By measuring this, we can get the residual torque we want.
