An elevator drive sheave for use with a coated steel cord includes a metal body and a divider. The metal body has a shallow circumferential groove having a groove depth. The grooves are separated from each other by a divider extending out of the metal body substantially greater than the depth of the grooves. The separator is made of or provided with a low friction cover layer. A coefficient of friction between the separator and the covering layer of the coated steel cord is much lower than a coefficient of friction between the metal body and the covering layer of the steel cord. The metal body may be assembled from discs each having a single groove. And the width of the groove is smaller than the diameter of the coated steel cord, so that the friction force of the coated steel cord can be further influenced. An elevator comprising a coated steel cord extending over a sheave is also claimed.

    一种与被包覆的钢帘线一起使用的电梯驱动槽轮,包括金属主体和分隔器。金属主体具有浅的周向凹槽,周向凹槽具有凹槽深度。凹槽通过延伸出金属主体远大于凹槽深度的分隔器彼此分开。分隔器由低摩擦覆盖层制成或设置有低摩擦覆盖层。分隔器和被包覆的钢帘线的覆盖层之间的摩擦系数比金属主体和钢帘线的覆盖层之间的摩擦系数低得多。金属主体可以由各自具有单个凹槽的盘形件组装而成。通过使凹槽宽度小于被包覆的钢帘线的直径,可以进一步影响被包覆的钢帘线的摩擦力。还要求保护一种包括在槽轮上延伸的被包覆的钢帘线的电梯。
