在这项研究中，提出了一种利用摩擦力锁定平带的新型机构。该机构由两个重要元件组成;平带在与曲面接触时折叠并重叠，并且可以通过使用约束辊来改变接触区域。这两个元素的前允许一个带被锁定时，施加一个大的张力，由于合成摩擦力，本文提出了一些理论来分析这种机制。同时，这两个元件中的后者确保带保持锁定或解锁，并且它仅使用少量的动力将带的状态从锁定切换到解锁（反之亦然），尽管大的力被施加到带。因此，所提出的机构导致用于平带的有效锁定装置。这种机制，以及相关的理论方程，进行了实验验证，并使用所提出的机制的实际设计的一个例子进行说明。
In this study, a novel mechanism that locks a flat belt using frictional force was proposed. The mechanism is composed of two important elements; the flat belt folds back and overlaps itself while coming into contact with a curved surface, and the contact region can be changed through the use of constrained rollers. The former of these two elements allows for a belt to be locked when a large tensile force is applied due to the resultant frictional force; some theories for analyzing this mechanism are proposed in this paper. The latter of the two elements, meanwhile, ensures that the belt remains locked or unlocked, and it switches the state of the belt from locked to unlocked (and vice versa) using only a small amount of power, despite a large force being applied to the belt. The proposed mechanism therefore results in an efficient locking device for flat belts. This mechanism, and the associated theoretical equations, were validated experimentally, and an example of a practical design using the proposed mechanism is described.
