Abstract

The invention discloses a production technology of an oblique tooth-shaped edge-cut triangular belt. The production technology comprises viscose blending according to technical requirements, mixing, calendaring, reversing splicing, molding, oblique tooth-shaped rubber sleeve preparation, vulcanization, cutting and grinding. The base rubber layer is prepared from an oriented nylon fiber-rubber compound and a nylon fiber group is transversely and orientedly arranged in a triangular belt compressed layer so that the lateral rigidity and resistance to side pressure load of the triangular belt are obviously improved, the load is uniformly distributed on the whole strengthening layer and the dynamic mechanical properties of the triangular belt are improved. The oriented nylon fibers are added into the base rubber layer so that hardness and impact strength of the base rubber layer are improved. The oriented nylon fiber-rubber compound can effectively prevent early damage of the surface of the triangular belt, improve wear resistance, improve holding power between the triangular belt and a grooved wheel, reduce transmission noise and satisfy maintenance-free technical requirements.

Description

technical field

[0001] The invention belongs to the technical field of transmission belt preparation, and relates to a toothed V-belt produced with rubber as a raw material, in particular to a production process of a helical-toothed edge-trimmed V-belt. Background technique

[0002] V-belt is a kind of conveyor belt widely used in various machinery. It is mainly composed of industrial canvas, polyester soft cord and fiber glue layer. The fiber glue layer is mainly composed of natural rubber, styrene-butadiene rubber, reclaimed rubber and compounding agent. (zinc oxide, stearic acid, anti-aging agent, carbon black, softener, etc.). During the use of the V-belt, the friction between the pulley and the pulley will increase and generate heat of 110°C. With the operation of the V-belt, the heat emitted will always surround the belt body, and the ambient temperature will increase. , so that the temperature of the belt itself will also rise. Rubber is a thermoplastic material. Whe...
