Abstract
This paper describes the load-sensitive screw clamping mechanism to realize self high speed and high torque mode change. In order to realize the automatic mode change with just only the mechanical configuration, we adopt the worm screw mechanism. Linear motion of the worm screw can rotate the worm gear faster, on the other hand, the rotational motion of the worm screw car rotate the worm gear slower, this means the high torque is transmitted on this mode. Based on this principle, the prototype model was designed and developed. The basic motion of the prototype was confirmed experimentally.
