Zusammenfassung
An approximation method is proposed to achieve the contribution of the square drive eccentricity in transfer torque wrench calibrations. This systematic contribution can thus be quantified and eliminated. By doing this, the influence of the contact surfaces in the square drive can be estimated more precisely. The approximation succeeds not only at complete 4-position calibrations but also - with the help of a numerical fit - with calibrations over only 3 positions, a procedure which is required in the current German guideline for torque wrench calibrations. The proposed method has been validated through a survey of transfer torque wrench calibrations and through Monte Carlo simulations
