Problems solved by technology

[0004] 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

[0022] 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 discloses a jointed toothed V belt. The jointed toothed V belt is characterized by sequentially comprising a top cloth layer, a stretching layer, a bonding layer and a compression layer from outside to inside, wherein a strengthening layer is distributed in the bonding layer; a pressure resistant layer is distributed in the compression layer; the main body glue of the stretching layer, the bonding layer and the compression layer is ternary ethylene propylene rubber; and the main body glue of dipping treatment latex or mucilage of the top cloth layer, the strengthening layer and the pressure resistant layer. Compared with the prior art, the jointed toothed V belt has the advantages that: because the ternary ethylene propylene rubber is used as the main glue, the cold resistance of the jointed toothed V belt is improved by reasonable layout of structural level and combination of proportioning of specific raw materials of each layer, meanwhile, various physical properties are greatly improved, and reliable and stable use of the jointed toothed V belt is ensured.

Description

technical field [0001] 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 [0002] 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. [0003] At present, combined toothed V-belts are generally used in high-power mechanical equipment, and their main raw materials are natural rubber or neoprene. For such open documents, please refer to the Chinese utility model patent "A Combined Belt" with the patent number ZL2005200277...
