Abstract
Generally there is provided an improved design for a nutrunner appliance drive mechanism and strain gauge mounting. The design for the drive mechanism and strain gauge mounting of the nutrunner appliance facilitates placement of the strain gauge nearer the nut engagement extremity. The drive mechanism includes a shaft member mounted at an angle transverse to the motor shaft, and having a beveled gear at one extremity and a nut engaging member on the other extremity. A strain gauge is mounted between these extremities and provides signals to contacts rotating with the shaft. A brush contact protruding from a removable terminal block is used to pick up the electrical signals from the strain gauge contacts.
