The development of cutter rotation drive system by the oil-pressure jack

Abstract

In this actuation system, a flexible maneuver of oil-pressure jack in transformed to rotary motion through crank system, and cutter is rotated. Moreover, by using oil-pressure jacks, maintenance is made easy and cost can be saved. In this experiment, it established that the revolution by the oil-pressure jacks is controlled with jack stroke. Telescopic motion of two or more jacks is overlapped and it its worked efficiently.
This results came from when it had arranged that the centerline of oil-pressure jack is not overlap, revolution torque was obtained efficiently and revolution of cutter is also stabilized was obtained as a result of this experiment.
