Abstract
A torque sensing device includes an idle wheel disposed between a force input shaft and a force output shaft, the idle wheel receives a tangential force from the force input shaft and the force output shaft to generate a counterforce as a loading, the center of the idle wheel is pivotally disposed on a positioning beam or a basis nearby, the positioning beam has a beam central line where a strain gauge installed. The positioning beam transforms the loading of the idle wheel along the beam central line to a normal force on the cross section of the positioning beam along the beam central line, the positioning beam generates a strain due to the normal force on the cross section of the positioning beam, the strain gauge detects the strain as the torsion sensing value of the output shaft on the region between the force input shaft and the force output shaft. A rotational driving tool is combined with the torque sensing device to improve the detecting precision of the torsion.
