Abstract

A kind of double cog band, including outer rubber layer, inner rubber layer, are provided with cushion gum layer between outer rubber layer and inner rubber layer, the cushion gum layer is embedded with the aramid line layer for being wound by aramid fiber or being woven；Outer rubber layer and inner rubber layer surface are respectively separated the tooth that passing power is distributed with.The utility model provides a kind of double cog band, improves the performance of double cog band, has high abrasion, the characteristic of high intensity.

Description

Double cog band

Technical field

The utility model belongs to transmission belt technical field, refers in particular to a kind of double cog band.

Background technology

Double cog synchronous belt, with light structure, without slippage engaged transmission, low noise the features such as by it is vast machinery, weaving, essence The industries such as close instrument and meter, petrochemical industry, communication cable understanding, approve and be widely applied.It not only combines gear The advantages of transmission, Chain conveyer and V belt translation, the shortcomings of overcoming other drive belt slips, extend, constitute a kind of unique biography Flowing mode.

There is the problem of wearing no resistance, low intensity in existing double cog band, therefore be used in some spies using two-sided toothing The different occasion life-span is shorter, and as using on atv motorcycle, the sand grains on sandy beach easily wears double cog band, causes to damage.

The content of the invention

The purpose of this utility model is to provide a kind of double cog band, improves the performance of double cog band, has high abrasion, height The characteristic of intensity.

What the purpose of this utility model was realized in：A kind of double cog band, including outer rubber layer, inner rubber layer, outer rubber Cushion gum layer is provided between glue-line and inner rubber layer, the cushion gum layer is embedded with the aramid line layer for being wound by aramid fiber or being woven； Outer rubber layer and inner rubber layer surface are respectively separated the tooth that passing power is distributed with.

Preferably, the inner rubber layer is made up of abrasive rubber.

Preferably, the elastic layer of cloth of inner rubber layer surface distributed.

Preferably, double cog band described in sulfidization molding between the outer rubber layer, cushion gum layer and inner rubber layer.

Preferably, the tooth on outer rubber layer and the inner rubber layer surface staggeredly or symmetric arrays.

Compared with prior art, the beneficial effects of the utility model are：Aramid fiber is a kind of new high-tech synthetic fibers, tool There is the premium properties such as superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, in light weight, insulation, anti-aging, life cycle length, will It is not easy off-line, and can lift the tensile strength of double cog band in cushion gum layer；Cushion gum layer causes the tooth on two sides to have There is buffer capacity, impact resistance is good, increases the service life.

Brief description of the drawings

Fig. 1 is structure chart of the present utility model.

Reference:1st, outer rubber layer；2nd, inner rubber layer；3rd, cushion gum layer；4th, elastic force layer of cloth；5th, aramid line layer.

Embodiment

The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1：

A kind of double cog band, including outer rubber layer 1, inner rubber layer 2, buffering is provided between outer rubber layer 1 and inner rubber layer 2 Glue-line 3, the cushion gum layer 3 are embedded with the aramid line layer 5 for being wound by aramid fiber or being woven；Outer rubber layer 1 and the surface of inner rubber layer 2 It is respectively separated the tooth that passing power is distributed with.

Preferably, the inner rubber layer 2 is made up of abrasive rubber.

Preferably, the elastic layer of cloth 4 of the surface distributed of inner rubber layer 2.The surface of 4 surface inner rubber layer of elastic force layer of cloth 2, prolongs Long life.

Preferably, double cog band described in sulfidization molding between the outer rubber layer 1, cushion gum layer 3 and inner rubber layer 2.

Preferably, the tooth on outer rubber layer 1 and inner rubber layer 2 surface staggeredly or symmetric arrays.

Compared with prior art, the beneficial effects of the utility model are：Aramid fiber is a kind of new high-tech synthetic fibers, tool There is the premium properties such as superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, in light weight, insulation, anti-aging, life cycle length, will It is not easy off-line, and can lift the tensile strength of double cog band in cushion gum layer 3；The material of cushion gum layer 3 selects hardness Less than inner rubber layer 2 and the sizing material of outer rubber layer 1 so that the flexible buffer capacity of tooth on two sides, impact resistance is good, extends Service life.

Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model Within the scope of.
