摘要： A belt for suspending and/or driving an elevator car extending longitudinally along a length of the belt. An inner belt layer formed from a first material is bonded to the plurality of tension elements at a first side of the belt. The inner belt layer forms an inner belt surface interactive with a traction sheave of an elevator system. An outer belt layer formed from a second material is bonded to the plurality of tension elements at a second side of the belt. The plurality of tension elements are located between the first side and the second side.

摘要： A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending longitudinally along a length of the belt and a plurality of fibers interlaced with the plurality of tension elements forming a composite belt structure. A coating at least partially encapsulates the composite belt structure to improve two or more operational characteristics of the belt. A method of forming a belt for suspending and/or driving an elevator car includes forming a plurality of tension elements and arraying the plurality of tension elements longitudinally along a belt. A plurality of fibers are interlaced with the plurality of tension elements to form a composite belt structure. A coating is applied to at least partially encapsulate the composite belt structure to improve at least two operational characteristics of the belt.

摘要： A method of forming a belt for suspending and/or driving an elevator car includes arraying a plurality of tension elements longitudinally along a belt and interlacing a plurality of warp fibers and a plurality of weft fibers with the plurality of tension elements to form a composite belt structure. A coating is applied to at least partially encapsulate the composite belt structure. The coating includes a base coating material and at least one additive mixed with the base coating material to improve an operational characteristic of the belt.

摘要： A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending along a length of the belt and a plurality of belt fibers transverse to the plurality of tension elements and interlaced therewith. The belt fibers define at least one traction surface of the belt. An edge fiber is located at a lateral end of the belt transverse to and secured to the plurality of belt fibers to secure the belt fibers in a selected position.

摘要： A belt for suspending and/or driving an elevator car includes a plurality of cords. Each cord includes a plurality of wires and at least one yarn thread disposed at an outer periphery of the plurality of wires. An elastomeric jacket substantially retains the plurality of cords. The at least one yarn thread is configured to promote adhesion of the elastomeric jacket to the plurality of cords and reduce fretting of the plurality of wires. A method of forming a belt includes arranging a plurality of wires into a cord, arranging one or more yarn threads at an outer periphery of the plurality of wires, arranging a plurality of cords into a selected arrangement and applying an elastomeric jacket to the cords to retain the cords. The one or more yarn threads are configured to promote adhesion of the elastomeric jacket to the cords and reduce fretting of the wires.

摘要： An illustrative example assembly for making an elevator load bearing member includes a fabric having a plurality of fibers arranged with some of the fibers transverse to others of the fibers. A plurality of cords are configured to support a load associated with an elevator car. The cords are included in the fabric and have respective coatings. The coatings include a first coating material and a second coating material, or include different coating thicknesses such that some of the coatings have a different coating thickness than others of the coatings, or the coatings include the first coating material and the second coating material and some of the coatings have a different coating thickness than others of the coatings.
