Problems solved by technology
[0003] The addition of small diameter steel filler wire adds an additional manufacturing step with a corresponding increase in cost
Additionally, steel filler wire increases the stiffness of the rope, which results in higher bending stresses and reduced rope life

Embodiment Construction
[0030] exist Figure 1A , Figure 1B and Figure 1C A schematic diagram of an exemplary traction elevator system 10 is shown in . Features of the elevator system 10 that are required for an understanding of the invention (eg, guide rails, safety equipment, etc.) are not described herein. Elevator system 10 includes an elevator car 12 operatively suspended or supported in a hoistway 14 by one or more straps 16 . One or more straps 16 interact with one or more pulleys 18 for guidance around various components of elevator system 10 . One or more straps 16 may also be connected to counterweights 22 that serve to help balance elevator system 10 and reduce differences in strap tension on either side of the traction sheave during operation.
[0031] The pulleys 18 each have a diameter 20 , which may or may not be the same as the diameter of the other pulleys 18 in the elevator system 10 . At least one of the pulleys 18 may be a drive pulley. The drive pulley is driven by the mac...

A belt for suspending or driving an elevator car includes a plurality of wires arranged into one or more cords; and a jacket substantially retaining the one or more cords. At least one of the one or more cords includes a plurality of non-load bearing filler filaments interposed between adjacent wires of the plurality of wires. An elevator system includes an elevator car, one or more sheaves, and one or more belts operably connected to the car and interactive with the one or more sheaves for suspending or driving the elevator car. Each belt of the one or more belts includes a plurality of wires arranged into one or more cords and a jacket substantially retaining the one or more cords. At least one of the one or more cords includes a plurality of non-load bearing filler filaments interposed between adjacent wires of the plurality of wires.
Description
technical field [0001] The subject matter disclosed herein relates to tensile components, such as those used in the suspension and / or drive of elevator cars and / or counterweights in elevator systems. Background technique [0002] Tensile members for elevators generally comprise one or more cords formed from a plurality of steel wires arranged in a geometrically stable configuration. Depending on the wire diameter, only certain geometrically stable arrangements are possible. The cords are often arranged in a belt comprising a plurality of such cords at least partially enclosed in an elastomeric sheathing material. In strap construction, the interaction between the wire rope material and the individual strands with the sheath material is the primary basis for rope to sheath adhesion and bonding unless additional adhesion is used. Relatively small steel wires, also known as "fill wires", may be added to the rope construction to fill gaps in the rope construction and allow the...
