Problems solved by technology

However, since the steel core or steel wire rope is still used as the main force carrier in the elevator traction load-bearing member, and the specific gravity of the steel core or steel wire rope is still high, it is difficult to further improve the elevator traction load-bearing member under the premise of meeting the strength requirements. reduce own weight

Abstract

The invention discloses an elevator traction bearing component and an elevator. The elevator traction bearing component comprises one or more traction bearing units; each traction bearing unit includes a polymer substrate, and at least one nonmetal fiber embedded in the polymer substrate and continuously extending in the length direction of the traction bearing unit; the nonmetal fibers are glass fibers, carbon fibers or nylon fibers; and diameters d of the nonmetal fibers are 3-80 microns. The nonmetal fibers are leaded into the elevator traction bearing component to realize lighter design of the elevator traction bearing component, so that the weight of the elevator traction bearing component is largely reduced, and the use noise of the elevator traction bearing component is lowered. The elevator adopting the elevator traction bearing component with lighter design can be more suitable for a compact building hoistway to improve the elevator operation comfort.

Description

technical field [0001] The invention relates to an elevator traction bearing member and an elevator used for transmitting power and lifting a car in an elevator. Background technique [0002] In the traction elevator, the relative movement of the car and the counterweight is achieved by the friction between the traction rope and the traction wheel. This force is called traction or driving force. The traction rope is one of the elevator traction load-bearing components. Most of the current elevators use steel wire ropes as the elevator traction load-bearing components. However, with the development of elevator technology, elevator traction load-bearing components are developing in the direction of light weight. Due to the disadvantages of heavy weight, large diameter and high noise, traditional steel wire ropes cannot meet the needs of elevators with limited installation space and lightweight design. need. In order to solve such problems, elevator traction load-bearing com...
