Abstract
PURPOSE: To improve the precision of torque measurement by connecting the tip of a leaf spring, fitted to a driven shaft in the tangent direction, to an arm provided to the driving shaft and by sticking on the leaf spring a strain gauge detecting torque.
CONSTITUTION: When driving shaft 1 is turned, its turning is transmitted to driven shaft 2 by way of arm 5 and leaf spring 6. Then when no load is applied on driven shaft 2, leaf spring 6 stays upright and as the load increases, leaf spring 6 deforms bending. Additionally, projecting adjustment screw 8 to a certain degree causes leaf spring 6 strike the tip of adjustment screw 8 when leaf spring 6 increases in bending deformation, and consequently while the bending deformation is restrained, the opposite bending deformation is partially caused. As the leaf spring bends, strain gauge 7 stuck on it generates outputs (a), (b) and (c) corresponding to the turning states of A, B and C. Thus, the variation of the strain of leaf spring 6 attending torque variation is great, so that the measurement precision will improve.
