    Abstract: A wire rope has an independent wire rope core including lubricated individual core wires that are encapsulated in a tubular sheath of elastomeric or polymeric material surrounding the core wires and retaining the lubricant. A plurality of strands are located radially outwardly from and adjacent to the core. Each of the strands include strand wires that are lubricated. The strand wires are encapsulated in a tubular sheath of elastomeric or polymeric material that retain the lubrication for the strand wires. The core and strand encapsulating materials prevent direct metal-to-metal contact between core wires and strand wires, and between strand wires of adjacent strands. The core and strand encapsulating materials are applied in a manner so as to avoid loss of lubricant. Retaining lubrication and preventing direct metal-to-metal contact significantly improves the useful life of the wire rope.

    Abstract: A tension member for an elevator system has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member. In a particular embodiment, the tension member includes a plurality of individual load carrying cords encased within a common layer of coating. The coating layer separates the individual cords and defines an engagement surface for engaging a traction sheave. The individual cords are constructed of several strands and each strand is separated from direct contact with each other strand by polymeric material. While aspect ratios of greater than one are preferred, tension members of other ratios including round also benefit from the prevention of direct contact.

    Abstract translation: 用于电梯系统的张力构件具有大于1的纵横比,其中纵横比被定义为张力构件宽度w与厚度t(w / t)的比率。 纵横比的增加导致与常规电梯绳索相比最大绳索压力的降低和增加的柔性。 结果,这种类型的张力构件可以使用较小的滑轮。 在一个具体的实施例中,张紧构件包括多个单独的承载绳,其包裹在公共涂层内。 涂层分离各个帘线并且限定用于接合牵引轮的接合表面。 单个帘线由多根股线构成,并且每股线与聚合物材料与彼此线直接接触分开。 虽然优选大于1的纵横比,但是包括圆形的其它比例的张力构件也可以从预防直接接触中受益。
