Abstract

The invention relates to the field of driving belts, and discloses a preparation method of a high-performance molded elastic multi-wedge belt and a mold device therefor. The preparation method solves the problems that the existing multi-wedge belt preparation technology usually adopts a production mode of preparing a wedge by a profiling grinding wheel, and thus in production, raw material consumption and energy consumption are high and in multi-wedge belt running, large noise and wedge wearing can be produced easily. The preparation method of the high-performance molded elastic multi-wedge belt comprises the following steps of A, preparing a rubber sleeve, B, carrying out pretreatment on a rubber sheet, C, rolling the pretreated rubber sheet, D, pasting the rolled rubber sheet to obtain a belt cylinder, E, vulcanizing the belt cylinder, and F, cooling and cutting to obtain a finished product. The preparation method of the high-performance molded elastic multi-wedge belt has the advantages of low raw material consumption, low energy consumption and excellent product quality.

Description

technical field [0001] The invention relates to the field of transmission belts, and relates to a method for manufacturing high-performance molded elastic ribbed belts and a mold device thereof. Background technique [0002] The V-ribbed belt refers to an endless rubber transmission belt with a flat belt as the base body and equidistant trapezoidal wedges arranged on the inner surface, and its working surface is the side of the wedges. The advantages of the V-ribbed belt are: the contact area and friction between the V-ribbed belt and the pulley are large, and the load is distributed evenly along the belt, so the transmission capacity is greater; The working stress is small, and it can work on smaller pulleys; the V-ribbed belt also has the characteristics of small transmission vibration, fast heat dissipation, stable operation, small elongation in use, large transmission ratio and high limit linear speed, so the service life is longer; energy-saving effect Obviously, the t...
