| Research Abstract |
This paper proposes a load-sensitive continuously variable transmission (CVT) driven by vibration. Its reduction ratio change automatically in response to the load. The CVT can transmit a power through a structure of machine and needs not a drive mechanism such as gear, shaft, pulley and belt. It is compact and simple. We have developed a remarkably small CVT and its size is 5mm in diameter and 15mm in length. It can install in an endoscopic surgical instruments. We experimentally verified that the CVT can drive a forceps.
