摘要:
An exemplary method of making a first component for contacting another component includes applying a wear and corrosion resistant material layer onto a surface of the first component. The wear and corrosion resistant material layer is then roughened subsequent to having been applied to the surface. A component comprises an exemplary elevator sheave that includes a metallic body having a sheave surface that is adapted to contact an elevator tension member. A corrosion resistant material layer on the sheave surface has a thickness that is greater than about 5 microns.

An elevator load bearing member assembly includes at least one roughened surface (46) on a polyurethane jacket (44). In one example, mechanical roughening is used to roughen the surface (46) after the jacket has been extruded onto tension members (42). In another example, the temperatures used for molding a jacket (44) are controlled to induce melt fracture and roughen the surface (46) during the forming process. Other examples include chemically roughening the jacket surface and using localized heating to roughen the surface. The roughened jacket surface improves friction characteristics of a load bearing member assembly.
摘要:
A belt and a method for manufacturing a belt is provided. The belt includes a plurality of lengthwise-extending tension members and a jacket. The jacket substantially retains the plurality of tension members. The jacket has a first side region, a second side region, and a center region between the first and second side regions. The first and second side regions of the jacket are more fire retardant than the center region of the jacket.
