A method of determining the torque within a torque transmitter of a gear unit comprising measuring by non-contacting means the angular windup of the torque transmitter, determining the mechanical torsional stiffness of the torque transmitter and then calculating the torque by multiplying the angular windup by the torsional stiffness of said torque transmitter. The angular windup may be determined by comparison of the instantaneous angular deviation between two spaced apart regions of the torque flow path of the torque transmitter when under load with the instantaneous angular deviation between the same two regions when the torque transmitter is rotating in a zero torque transmitting state. |
