Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0024] It should be noted that when a component is said to be "connected" to another component, it may be directly connected to the other component or intervening components may also exist. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary s...

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.
Description
technical field [0001] The present application relates to the technical field of traction belts, in particular to an elevator traction belt. Background technique [0002] With the advancement of elevator technology, more and more elevators use traction belts to cooperate with traction wheels for power transmission. The forms of traction belts include flat steel belts, ribbed belts, etc. The body and the covering body wrapped outside the carrier body. [0003] Due to the constant contact between the covering body and the traction wheel, the traction belt will be worn during operation, especially when foreign matter (such as sand) enters the gap between the traction belt and the traction wheel, the foreign matter will be crushed by the traction belt. Increased wear and tear on the traction belt. When the wear of the traction belt reaches a certain amount, especially to the bearing body, the bearing body and the traction sheave will be in direct contact, and the wear will acc...
