CouplingThe nominal torque is blunt, that is, what is the force on the shaft?Then multiply it by the radius of the shaft, which is called torque. The nominal torque of the coupling is the limit value to ensure that the coupling does not cause fatigue damage when the shaft is twisted.
Some friends will ask how to know its torque, or what instrument to measure it?Measuring the torque of the coupling is actually measuring the torque of the rotating shaft. A rotating sensor and a torque measuring instrument must be used. The sensor is connected to the shaft in series, and the sensor must be qualified by the measurement agency.First, we need to estimate the size of the shaft torque to select the sensor. The shaft torque can be calculated by the shaft power and speed to get the calculated value. Use the sensor to measure the actual value.
