What is the nominal torque of the coupling?That is, the force on the shaft, multiplied by the radius of the shaft, 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.
How to measure torque?In fact, to measure the torque of the rotating shaft, a rotation sensor and a torque measuring instrument must be used, and the sensor is connected in series with the shaft.The sensor must be qualified by the measurement machinery.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. The sensor is used to measure the actual value.
