    • A brake device is disclosed which has a function to adjust a speed of a hoisting machine, or stop the hoisting machine as a constituent element of an elevator system. The brake device includes: a rotating braked body having a rotary shaft interlocked with a rotation of the hoisting machine; a plurality of pads which are disposed on a surface of the rotating braked body in an attachable and detachable manner and have a function to give a braking force to the rotating braked body; and a plurality of calipers holding the pads. The plural calipers are structurally identical to each other, the pads have a pressing part to contact the surface of the rotating braked body and a recessed part not to contact the surface of the rotating braked body, and a position on the rotating braked body which contacts the pressing part of the pad in one of the calipers is different from a position on the rotating braked body which contacts the pressing part of the pad in another caliper. Thus, the frictional heat caused by the pads of the brake device can be reduced or dispersed, and also the calipers for holding the pads are made structurally identical so that assembling work and adjusting work can be easy.
    • 公开了一种制动装置,其具有调节曳引机的速度或停止作为电梯系统的组成元件的曳引机的功能。 该制动装置包括:旋转制动体,该旋转制动体具有与曳引机的旋转联动的旋转轴; 多个垫片,其以可拆装的方式设置在旋转的制动体的表面上,并且具有对旋转的制动体给予制动力的功能; 以及保持垫的多个卡钳。 多个卡钳在结构上彼此相同,垫具有与旋转的制动体的表面接触的挤压部和不与旋转的制动体的表面接触的凹部以及旋转的制动体上的位置, 在一个卡钳中的垫的按压部分不同于在另一个卡钳中接触垫的按压部分的旋转的制动体上的位置。 因此,由制动装置的衬垫引起的摩擦热可以减小或分散,并且用于保持衬垫的卡钳在结构上相同,从而可以容易地进行组装工作和调整工作。
