在由单绳缠绕式提升机或落地式多绳摩擦提升机组成的提升系统中,天轮是重要的组成部分之一。在材料和制造等不存在缺陷的情况下,天轮使用寿命的长短在很大程度上取决于轮缘使用寿命。因此,延长轮缘的使用寿命对延长天轮使用寿命具有十分重大的意义。为了增加轮缘和钢丝绳的使用寿命,不少矿山采用了带衬垫的轮缘。其中除了铸铁轮缘必须采用衬垫以外,铸钢和焊接轮缘采用衬垫的也不少。带衬
In a lifting system consisting of a single rope winder or a floor-mounted multi-rope friction elevator, the sheave is one of the important components. In the absence of materials and manufacturing defects, the life of the celestial wheel depends largely on the service life of the rim. Therefore, to extend the service life of the rim to extend the service life of the wheel is of great significance. In order to increase the service life of the rim and wire rope, many mines use padded rims. In addition to cast iron flanges which must be used in addition to castings and welded flanges also use a lot of liner. Lined
