Dynamic off-axis torque wrench compensation

Abstract:

A torque wrench is provided that extends along a longitudinal axis and includes a head, a body, and a torque adjustment assembly. The head is shaped and adapted to engage at least one of a fastener or a torque-application adaptor aligned with a torque axis. The body includes a handle and a click-pivot assembly. The click-pivot assembly includes first and second members coupled by a link, and is configured to indicate application of a predetermined amount of torque via the handle. The head is pivotally coupled to the body via the torque adjustment assembly. A change in an angle between the torque axis and the longitudinal axis dynamically adjusts an amount of torque provided by the head by a predetermined amount relative to the predetermined amount of torque applied via the handle.
