Problems solved by technology

For example, the temperature of the transmission belt of an automobile engine can reach 120°C when it is normal, and the instantaneous high temperature can reach 150°C, while the winter temperature in the North and South Poles and Russia is below -40°C. In these cases, the service life of the V-belt used in mechanical transmission Often extremely short, often forced to use expensive and complex mechanical transmission methods such as chains
[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 needs of reality has always been an object worthy of research

Embodiment 1

[0019] Embodiment 1: as figure 1 As shown, the 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 sequentially from outside to inside, and a strength layer 3 is arranged inside the adhesive layer 4. 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 lateral rigidity of the V-belt and ensure the force on the center of the strength layer The position is at the position of the nodal line that is not bent or compressed; the adhesive layer can enhance the adhesion between the strength layer and other layers, and at the same time buffer the impact of the belt stretching and bending on the strength layer; the main working surface of the compression layer belt, and the pulley Friction transmits power.

Abstract

The invention discloses a tooth-type V-shaped belt, which is characterized by comprising a top cloth layer, a stretching layer, an adhesive layer and a compression layer sequentially from outside to inside, wherein a strong force layer is arranged inside the adhesive layer. Compared with the prior art, the invention has the advantages that: due to the rational arrangement of structural layers, the cold tolerance of a product is improved by combining the proportion of the raw materials of each layer, and physical characteristics are greatly improved at the same time, so that the product can bereliably and stably used.

Description

technical field [0001] The invention relates to a mechanical transmission belt, in particular to a toothed V-belt for transmitting mechanical power, which is mainly used in some motor vehicle equipment. Background technique [0002] At present, most of the V-belt materials used in mechanical transmission are natural rubber or neoprene. The effective use temperature range of natural rubber is -20°C to 80°C, and the effective use temperature range of neoprene is -20°C to 100°C. range, the service life of the V-belt will be greatly reduced. For example, at a service temperature of 120°C, the service life of the existing V-belt with natural rubber or neoprene as the main material does not exceed 30 hours; at a service temperature of -40°C Under normal circumstances, these two types of belts have lost their elasticity, and their lifespan is only about 10 hours. [0003] With the expansion of the application field of the V-belt, its working temperature has more and more stringent...
