Title: TORQUE MEASUREMENT DEVICE, GEARBOX, AND TORQUE MEASUREMENT METHOD
Abstract:
This torque measurement device comprises: a sensor that measures the oscillation of at least one of a first shaft that is connected to rotating machinery, and a second shaft that rotates in conjunction with the first shaft; and a torque calculation unit that, on the basis of vibration information measured by the sensor, calculates the torque that is being applied to the shaft for which the sensor measured the vibration information.
