Abstract

PURPOSE:To express lost motion separately by an angle of play rotation due to the back gap of a transmission element and a torsion spring constant due to elastic deformation, by processing measurements of torque of rotation and an angle of rotation. CONSTITUTION:A measurement part 11 and a load device part 15 are coupled with a rotation transmitting device 1, rotation is fixed by a braking device 13, and a rotation driving device 7 is driven. Simultaneously with the starting of the rotation driving device 7, an arithmetic device 16 obtain torque T and an angle theta of rotation detected by a rotation torque detector 9 and a rotation angle detector 10 at specific intervals of time, and then stores them in a storage part 16b; and an arithmetic part 16a calculates the rate of variation in torque of rotation to the angle of rotation between adjacent measured values. The angle of rotation which satisfied dT/dtheta<=e (e: constant) is outputted from an output device 17 as an angle of play rotation due to a back gap between transmitting elements. From the gradient of a straight line function obtained by approximating measured values of torque and an angle of rotation which are not within said range to two straight lines, a mean gradient K is found and then outputted from the output device 17 as a torsion spring constant due to elastic deformation of a transmitting element.
