Abstract
The invention relates to an apparatus for measuring a torque, conducted through a rotatable machine element, by means of fork-shaped transmitter levers including tines which are connected with two parts which, when a torque is transmitted, resiliently rotate in relation to each other, and the fork handle of which is hinged on a transmitter ring, so that the relative rotation between the two previously mentioned parts generates an increased axial movement of the transmitter ring, which is detected as a measurement of the torque. To prevent an overload on the measuring device and breakage of its components in case of impermissibly high torque shocks, stops are provided which limit the relative rotation of the two parts which rotate in relation to each other during the transmission of torque to a value which corresponds to the maximally permissible stress on the material of the measurement apparatus.
