Abstract: A setting torque tool to tighten a screw or a similar fastener to a target torque is disclosed. The torque tool comprises a main body with a housing and a drive shaft, which is firmly attached to the housing to transfer a torque. The drive shaft has a connection area, to which a drive can be connected. An adapter for an operating tool rotates together with the housing and the drive shaft to transfer the torque, Sensor measure and evaluate the torque transferred. A release mechanism, which is arranged in the housing, releases the torque tool upon reaching a target torque.

Abstract: The invention relates to a torque sensor comprising an inner body, an outer annular body surrounding the inner body concentrically and webs connecting the inner body to the outer annular body in a star shape. Further on the torque sensor comprises a means for introducing torque and at least one measuring element on a web for determining deformation. The webs have the form of a u-profile.

Abstract: An operating device for testing torque wrenches is formed with a carrier for fixing a torque wrench to be tested. A transducer is coupled to the head portion of the torque wrench. A grip holder is provided for fixing the grip of the torque wrench and a deflecting mechanism is adapted for generating a torque to the head portion of the torque wrench to be tested. Further on a sliding mechanism is provided for sliding the grip in the grip holder without friction.

Abstract: The invention relates to a torque sensor for calibrating screwing tools such as dynamometric keys or impact screw drivers. A torque sensor for calibrating screwing tools has an inner body defining an axis with respect to which a torque is to be measured. The inner body has a seat for engaugement of a screwing tool to be calibrated. An outer annular body is held stationary. This outer annular body is coaxial with the inner body and is connected therewith through radial webs of a first type and through radial webs of a second type. The first type webs have relatively large widths circumferentially but have relatively small axial dimensions. The second type webs are relatively narrow circumferentially but have relatively large axial dimensions. The torque sensor further comprises torsion measuring elements attached to said first type webs for measuring torsional deformation due to torques exerted on said inner body.
