ABSTRACT:
A device for measuring the torque on an elongate shaft which is twisted as the shaft is subjected to torque. An elongate tubing is located around the shaft and is attached at one end to the shaft. A flange member is located adjacent the opposite end of the tubing and includes an outer rim which is flexibly mounted to the shaft. A camming mechanism is located between the rim and the end of the elongate tubing so that the rim is axially deflected as the shaft twists under the torque relative to the free end of the elongate tubing. The axial deflection of the rim is measured and the torque on the shaft is determined by the magnitude of this deflection. The axial deflection is conveniently measured by measuring the effect on fluid flow out of a nozzle located adjacent to the rim.
