Abstract
A device includes at least one magnetic field generator placed on a first plane of a right section of a shaft and at least one magnetic field detector placed in a second plane of a right section of the shaft. The detector produces a signal proportional to the torque following the relative angular shift of the field generator in relation to the detector, the magnetic field generator having a magnetic structure supported by support mechanisms connected to the turning shaft. The magnetic field detector is located roughly opposite the magnetic field generator and is supported by support mechanisms connected to the turning shaft.
Claims33
A device to measure torque on a turning shaft, the measuring device comprising:
- a mounting hub, positioned about a shaft, for applying torque to the shaft;
- deformable support means extending radially inwardly from the mounting hub to the shaft for supporting the mounting hub relative to the shaft such that torque applied to the mounting hub results in elastic deformation of the support means and relative rotation of the mounting hub about the shaft;
- and
- a sensor, fixed with respect to the shaft, for sensing relative movement of the mounting hub to produce a signal proportional to torque applied by the mounting hub to the shaft.
