无动力索道的控速器,就是在其卷筒上缠绕着牵引索,用来控制荷重跑车运行速度和停车的一种装置。根据钢索在控速器卷筒上绕入边和绕出边张力T与t之间的关系及钢索与卷筒间摩擦系数μ的大小,将决定着钢索往卷筒上不同的缠绕方法,一般由所必须的包角α来确定。单卷筒的控速器如图a所示,当索道的牵引索缠绕卷筒半圈时,其包角只有α=。如果 Non-powered ropeway speed controller, is in its reel wrapped around the traction cable, used to control the speed of the sports car load and parking a device. According to the wire rope in the speed control device into the edge and around the edge tension T and t between the relationship and the cable and the friction coefficient between the size of the reel will determine the winding of the wire to the winding of different The method, generally determined by the necessary wrap angle α. Single drum speed control as shown in Figure a, when the cable traction rope wound half a circle, the wrapping angle only α =. in case
