Method to determine torque acting on shaft; involves using rotation bodies, which are arranged around shaft sections to rotate with the shaft, where torque is determined based on detected rotary positions of bodies

摘要

The method involves using rotation bodies (3,4), e.g. annular gear sections, which are spaced longitudinally along and arranged about sections of the shaft. The torque is determined from the detected positions or movements of the rotatable bodies, using rotatable second rotation bodies (5,6). An Independent claim is included for a device for implementing the method.
