Problems solved by technology

However, the material of the above-mentioned cord fabric is usually a relatively single material, such as a single material such as nylon or polyester, which is difficult to take into account the strength of the conveyor belt and the shrinkage rate in the warp direction
In this way, after being heated for a long time, the belt will shrink in the warp direction, and the width shrinkage rate will be 2-3%, which shortens the service life of the conveyor belt.
In addition, the above-mentioned power transmission belt is usually prepared by manually winding the back rubber layer on the mold, then manually cutting, then winding the core wire layer and the bottom rubber layer, and then performing the vulcanization process. Such preparation steps are cumbersome and increase manufacturing cost

Embodiment Construction

[0017] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0018] refer to figure 1 , a power transmission belt, which can be a V-belt, a synchronous belt, a V-belt, etc., and is mainly used in a power transmission device of an automobile. The power transmission belt includes a primer layer 1 , a back glue layer 3 , a core layer 5 arranged between the primer layer 1 and the back glue layer 3 , and a cord fabric 7 arranged in the back glue layer 3 .

[0019] The above-mentioned cord fabric 7 includes warp threads 9 and weft threads 11 criss-crossing, wherein the density and strength of the warp threads 9 are higher than those of the weft threads 11, and the warp threads 9 are made of a blended material, while the weft threads 11 are made of a single material or a blended material. become. The density of the warp 9 is uniform, and its blended material is fo...

Abstract

The invention discloses a power transmission belt, which comprises a bottom rubber layer, a back rubber layer, a core layer arranged between the bottom rubber layer and the back rubber layer, and a cord fabric arranged in the back rubber layer. The cord fabric includes criss-crossing warp threads and weft threads, the density and strength of the warp threads are higher than those of the weft threads, and the warp threads are made of blended materials, while the weft threads are made of single or blended materials. The power transmission belt of the present invention not only has longer service life, but also has low production cost.

Description

technical field [0001] The invention relates to a power transmission belt. Background technique [0002] Power transmission belts are divided into V-belts, synchronous belts and V-belts, and various power transmission belts usually include a primer layer, a back rubber layer, and a cord layer or core layer between the primer layer and the back rubber layer. . During the mold forming process of the power transmission belt, the core wires in the core wire layer tend to move to the side close to the mold, resulting in different core wires in the radial direction and not in the same plane, so that when the power transmission belt is driven, different core wires The force of the power transmission belt is different, which makes the power transmission belt easy to break; individual core wires may even escape from the adhesive layer and rub against the pulley, making it more likely to fail; at the same time, such a power transmission belt is also more noisy during operation.
