Problems solved by technology

[0005] Although EPDM (Ethylene-Propylene-Diene Monomer, EPDM) has good low temperature resistance and high temperature resistance, its own defects such as poor tear resistance, poor dynamic fatigue resistance, and poor processability limit its use in transmission belts. The industry, especially the use of the V-belt industry, how to develop a new type of EPDM toothed V-belt to meet the actual needs has always been an object worth studying.

Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, the combined toothed V-belt in this embodiment includes a top fabric layer 1, a stretch layer 2, an adhesive layer 4 and a compression layer 5 from the outside to the inside. The adhesive layer 4 has a strength layer and a compression layer 5 respectively. A pressure-resistant layer 6 is distributed in it. Among them, the main rubber of the stretching layer, adhesive layer and compression layer is EPDM; °Warp and weft woven canvas; the strength layer is polyester cord treated with EPDM latex; the compression layer is polyester cord treated with EPDM latex. The top fabric layer is used to protect the belt surface and improve the wear resistance and scratch resistance of the belt surface; the strength layer is used to bear the longitudinal tension of the V-belt; the stretch layer is used to improve the transverse rigidity of the V-belt and ensure the stress position of the center of the strength layer ;The adhesive layer can enhance t...

Abstract

The invention provides a tooth-type jointing V-shaped belt which is characterized by comprising a top cloth layer, a stretching layer, an adhering layer and a compressing layer which are sequentially arranged from outside to inside, wherein reinforcing layers are distributed in the adhering layer; pressure resisting layers are distributed in the compressing layer; ethylene-propylene-diene monomer adhesives are served as the main adhesives of the stretching layer, the adhering layer and the compressing layer; and the ethylene-propylene-diene monomer adhesives are also the main adhesives for the latex or mucilage for dipping processing of the top cloth layer, the reinforcing layer and the pressure resisting layer. Compared with the prior art, the tooth-type jointing V-shaped belt has the advantages that the ethylene-propylene-diene monomer adhesives are adopted as the main adhesives, and the structural layers are reasonably distributed, so that the cold resistance of a product can be improved on the basis of the mixture ratio of special raw materials in each layer, and meanwhile, various physical properties also can be greatly increased, and the product can be ensured to be used stably and reliably.

Description

[0001] This application is a divisional application based on the Chinese invention patent application with the application number 201110088127.X, the application date is April 6, 2011, and the invention name is "Combined Toothed V-belt". technical field [0002] The invention relates to a mechanical transmission belt, in particular to a combined toothed V-belt for transmitting mechanical power, which is mainly used in some large-scale mechanical equipment. Background technique [0003] Earlier V-belts for mechanical transmission used a single structure. Later, with the continuous increase of transmission power, a single V-belt could no longer meet the requirements of use, and multiple V-belt transmissions appeared. In order to facilitate the synchronous transmission of multiple V-belts, and then There is also a combined toothed V-belt. At present, combined toothed V-belts are generally used in high-power mechanical equipment. [0004] At present, combined toothed V-belts are...
