Load-sensitive continuously variable transmission driven by vibration of structure

提出了一种振动驱动的负载敏感型无级变速器。它的减速比随着载荷的变化而自动改变。CVT可以通过机械结构传递动力，不需要齿轮、轴、皮带轮、皮带等传动机构。它是紧凑和简单的。我们开发了一种非常小的无级变速器，其尺寸为直径5 mm，长度15 mm。它可以安装在内窥镜手术器械上。我们通过实验验证了无级变速器可以驱动一把钳子。

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.
