The invention relates to an elevator traction belt which comprises a bearing body set located in the center, wrapping bodies wrapping the bearing body set and at least two isolation layers. The two isolation layers are arranged on the two sides of the bearing body set in the thickness direction of the elevator traction belt. In the thickness direction of the elevator traction belt, the wrapping bodies located on the same side of the bearing body set are divided into two layers, the corresponding isolation layer is arranged between the two layers, and the wrapping body, close to the bearing body set, of the two layers of wrapping bodies has the higher hardness. Compared with the prior art, the scheme has the advantages that the isolation layers can disperse the surface stress of the elevator traction belt and prevent the stress on the surface of the elevator traction belt from being transmitted to the inner layer of the elevator traction belt. When the surface layer of the elevator traction belt is damaged, the isolation layers can also prevent cracks on the surface layer of the elevator traction belt from stretching into the elevator traction belt, so that the wear resistance of the elevator traction belt is improved, and the service life of the elevator traction belt is prolonged.

    本申请涉及一种电梯曳引带,包括位于中心的承载体组、包覆所述承载体组设置的包覆体以及至少两组隔离层,两组隔离层沿电梯曳引带厚度方向布置于承载体组两侧;沿电梯曳引带厚度方向,处在承载体组同侧的包覆体分为两层,两层之间设置有所述隔离层,两层包覆体中靠近承载体组的一者具有较高的硬度,该方案相对于现有技术,隔离层能够将电梯曳引带表面应力进行分散,避免电梯曳引带表面的应力传递至电梯曳引带内层;电梯曳引带表层发生损伤状况时,隔离层还能够防止电梯曳引带表层的裂纹不会延伸至电梯曳引带内,以增加电梯曳引带的耐磨,提高电梯曳引带的寿命。
