The mechanical hysteresis and backlash on reduction gears for positioning mechanism, have significant effects on dynamic performances itself. So the Non-Backlash Reducers have been developed to eliminate the backlash, but they are not able to be eliminated the effects of the mechanical hysteresis. So that the hysteresis must be analyzed to improve these dynamic performances. In this report, at first the special rigid coupling with mechanical hysteresis of arbitrary amount are developed, so called "Mechanical Hysteresis Test Unit". The magnitude of mechanical hysteresis are defined using the developed unit. Then the evaluation methods of mechanical hysteresis influences are proposed for dynamic performances. And the hysteresis characteristics are tested using positioning mechanism with mechanical hysteresis test unit. It is proved that the hysteresis have large influences on these dynamic performances.
