Load-sensitive continuously variable transmission driven by vibration of structure

提出了一种振动驱动的负载敏感无级变速器。它的减速比根据负载自动改变。CVT可以通过机器的结构来传递动力，并且不需要诸如齿轮、轴、带轮和带的驱动机构。它是紧凑和简单的。我们已经开发了一个非常小的无级变速器，它的尺寸是直径5毫米，长度15毫米。它可以安装在内窥镜手术器械。我们通过实验验证了CVT可以驱动镊子。

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.
