  • Automatic torque calibration device
    Patent number: 8931324
    Abstract: The present invention provides an easy-of-use torque calibration device capable of improving workability and safety and attaining reduction in time of a torque calibration in calibrating a torque of a dynamometer. That is, the present invention includes a connecting shaft coaxially connected to a torque measurement rotor, a calibration arm integrally rotated with the connecting shaft, a plurality of calibration weights for applying loads to both ends of the calibration arm, a moving mechanism to move the connecting shaft between a connection position and a spaced position, and a rotating direction fixing mechanism for fixing the torque measurement rotor and the connecting shaft in the rotating direction at the connection position, and a control unit controlling the moving mechanism.
