Technical Field

The invention relates to the field of triangular belt preparation, in particular to a high-strength triangular belt.

Background

The triangle has two kinds of special belt core structure and rope core structure, which are respectively composed of wrapping cloth, top rubber, tensile body and bottom rubber. The triangular belt with the rope core structure is convenient to manufacture, general in tensile strength, low in price, widely applied, good in toughness and high in strength, and is suitable for occasions with high rotating speed. The prior art does not mention the manner of adding tension wire, except that the addition of reinforcing bars to the cushion gum provides an increase in strength.

Disclosure of Invention

In order to improve the mechanical strength of the V-belt by arranging the tension wires in the V-belt, the invention provides the following technical scheme:

a high-strength V-belt comprises wrapping cloth, top rubber, buffer rubber and bottom rubber; the top glue, the buffer glue and the bottom glue are sequentially arranged inside the wrapping cloth from top to bottom; the wrapping cloth is refined by all-cotton canvas, vinylon, polyester cotton and interwoven pulp-soaking cloth through the working procedures of calendering, forming, vulcanizing and the like; reinforcing ribs are arranged inside the buffer rubber; tension wires are arranged inside the top adhesive layer and the bottom adhesive layer, and the tension wires in the top adhesive layer are modified aluminum-plastic alloy wires; the tensile wires in the base rubber are nylon wires; the tensile wires form a fiber framework of top glue and bottom glue.

Furthermore, the aluminum-plastic alloy wires are woven by a warp knitting method.

Further, the nylon yarn is woven by a weft knitting method.

Furthermore, the reinforcing ribs are in a shape of a round strip.

The invention has the beneficial effects that: the special tensile wires are added into the top rubber and the bottom rubber respectively to form a fiber framework, so that the strength and the wear resistance of the V-belt can be greatly improved on the premise of ensuring the toughness of the V-belt.
