DEVICE FOR MEASURING TORQUE OF DRIVING UNIT

PROBLEM TO BE SOLVED: To provide a device for measuring torque of a driving unit, with simplified design and without the need for electric signals transferred from rotating components to a fixed receiver. SOLUTION: This invention is related to the device for measuring the torque of the driving unit. The device is composed of a torsional component loaded by the torque and a corresponding tubular base component 21 being rigidly connected to a first end of shaft 10 at a first end of tube 22 and surrounding the torsional component 9. A second end of tube 24 is supported on a second end of shaft 11. The two ends of tube 22, 24 are associated with transmitting components 16, 34 respectively. A relative position of the transmitting components in the rotational direction around an axis of rotation 8 is recorded by a sensing component 35 that is associated with a housing 1, generates a signal at the every time when the two transmitting components 16, 34 pass through, and transfers the signal to an evaluating unit 36 that determines the loaded torque based on deviation of the signal.
