Abstract: The present invention relates to torque application tools, such as an electronic torque screwdriver, with a multiple axis gyroscope (such as a 3-axis gyroscope or other type of gyroscope) and torque sensor that allows for simultaneous or sequential measurement of torque and angle around the axis of the tool. Targets for torque and angle measurements may be used to create algorithms to detect breakaway torque, residual torque, or to perform error proofing to ensure unique fasteners are tightened.

Abstract: A digital torque wrench is disclosed having a transducer beam with a reduced thickness web therein. At least one strain gauge sensor is mounted to the internal web to measure the shearing stress within the web as the wrench is rotated. By using such a reduced thickness web, mounting the sensors in opposed orientations, mounting the transducer beam to the torque wrench handle using first and second longitudinal flanking pins, and providing the transducer beam in a tapered shape, the resulting measurement of the torque wrench is very accurate. Moreover, a rotational interface module with digital display is provided to facilitate reading of the display by the user.

Abstract: A coupling for torque transmitting devices is disclosed. The coupling employs polygonally shaped first and second ends having retaining balls held within each of the corners of the polygon. Pin cones are provided in each of the first and second ends. Actuation of a set screw or the like causes each of the pin cones to push the retaining balls radially outwardly in a simultaneous fashion thereby engaging a first and second members to be coupled.

Abstract: A combination torque tool and torque tool analyzer that includes a housing and a portable tool that can be mounted on the housing. The housing has a control panel with indicator lights and control buttons on an upper surface thereof and contains inside it a torque transducer and torque level alarm circuitry. The portable tool can be used as a torque tool, such as a screwdriver, or a torque tool analyzer.
