Traction transmission belt and preparation method thereof

Abstract

The invention discloses a method for preparing a traction drive belt which comprises the following steps: firstly obtaining carbon fiber composite slender rods with diameter of 0.5-5mm after molding and curing carbon fiber beams which are doped with a resin adhesive solution under the action of attraction through a pultrusion mold; then arranging a plurality of carbon fiber composite slender rods in parallel along a length direction of a belt base, introducing into a belt building machine and recombining with elastic materials forming the belt base, forming a traction drive belt; finally performing a post-treatment according the use of the traction drive belt. Compared with the prior art, the preparation method of the invention has low cost, can satisfy the industry actual demand with continuous production. The characteristics of light weight, favorable toughness, corrosion resistance, fatigue resistance, favorable mechanical properties and the like of the carbon fibers are given full play, so that the prepared traction drive belt has the advantages of light dead weight and high operating efficiency, thereby lowering the energy consumption and saving the operating cost.

Description

technical field [0001] The invention relates to the technical field of traction transmission belts, in particular to a traction transmission belt and a preparation method thereof. Background technique [0002] At present, the traction transmission belt generally adopts twisted steel wire rope, that is, the steel cable as the main load-bearing component, such as the traction transmission component used for the up and down movement of the elevator. However, the common problem of this kind of traction transmission steel cable is: when the floor is high, the length of the steel cable required increases; when the load-bearing mass is large, thicker steel cables or the number of steel cables are required to achieve safe transmission. , Therefore, the dead weight of the transmission system will be greatly increased in the end, which will increase energy consumption accordingly and is not conducive to environmental protection. In addition, the bending radius of the steel wire rope ...

AI Technical Summary

Problems solved by technology

However, the common problem of this kind of traction transmission steel cable is: when the floor is high, the length of the required steel cable increases; when the load-bearing mass is large, thicker steel cables are required or the number of steel cables is increased to achieve safe transmission. , so, the weight of the transmission system will be greatly increased in the end, which will increase energy consumption accordingly and is not conducive to environmental protection

In addition, the bending radius of the steel wire rope is relatively large, resulting in a correspondingly large diameter of the traction sheave of the elevator lifting system, which will further increase the weight of the system

The fatigue and corrosion problems of steel cable metal materials are also relatively prominent shortcomings
