Description

Large circle machine transmission belt

Technical field

The utility model belongs to transmission belt technical field, more particularly, to a kind of large circle machine transmission belt.

Background technique

Existing conveyer belt is mainly integrally formed by rubber, and rubber is due to intensity difference easy fracture in use, and And to avoid band body is excessively thin from often increasing its thickness, bending degree-of-difficulty factor is caused in this way and is increased, causes transport resistance big, simultaneously Its rough surface of rubber product to only needing the transmission for the conveyer belt for playing transmission effect to increase unnecessary resistance, therefore has Necessity is improved.

Summary of the invention

The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of large circle machine transmission belt, It has the characteristics that structure is simple, long service life.

To achieve the goals above, the technical scheme adopted by the utility model is a kind of large circle machine transmission belt, including Band body, the band body successively include outer glue-line, strand layer and double wedge layer, the outer glue-line, strand layer and double wedge layer from outside to inside It is integrally formed, the double wedge layer is made of discontinuous protrusion, and the outer glue-line is equipped with smooth layer far from the side of strand layer.

Further, the cross section of the protrusion is Ω shape.

Further, the strand layer is formed by silk group injecting glue, and wherein silk group is formed by least 5 silk thread twistings.

Further, the outer glue-line with a thickness of 1 ~ 2mm.

Further, the double wedge layer with a thickness of 1 ~ 2mm.

Further, the outer glue-line and double wedge layer are constituted using polythene material.

After adopting the above structure, the utility model is compared to the prior art advantageously:

1. the double wedge layer of the utility model is made of discontinuous protrusion, so that strand layer part is exposed to be convenient in this way Band body is bent, wherein being divided into 0.1mm between the protrusion that is connected is direct, is avoided that gear and strand layer are in contact to avoid silk in this way Line layer occurs abrasion and prolongs the service life.

It, can be really when being divided into 0.1mm between the protrusion that is connected is direct in this way 2. the cross section of the utility model protrusion is Ω shape The centre distance for protecting adjacent protrusion is not less than 5mm, and energy is preferably and gear cooperates the thickness that can increase protrusion to greatest extent simultaneously Degree can not only increase and improve transmission efficiency with the contact area of gear, while increasing and wear range and then can prolong the service life.

Detailed description of the invention

Fig. 1 is the schematic cross-sectional view of the utility model longitudinal direction.

Fig. 2 is the schematic cross-sectional view of the utility model transverse direction.

Specific embodiment

As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model It encloses, the present invention will be further described with reference to the accompanying drawings and examples.

Embodiment, as shown in Fig. 1 to Fig. 2: a kind of large circle machine transmission belt, including band body, it is characterised in that: wherein band body It from outside to inside successively include outer glue-line 10, strand layer 20 and double wedge layer 30, wherein outer glue-line 10, strand layer 20 and double wedge layer 30 1 Body formed, barrel shaped tooth layer 30 is made of discontinuous protrusion, so that the exposed such energy in strand layer part is curved convenient for band body Song is avoided that gear and strand layer 20 are in contact to avoid silk thread wherein the direct interval L1 of the protrusion that is connected is 0.1mm in this way Layer 20 occurs abrasion and prolongs the service life, and is equipped with smooth layer 11 far from the side of strand layer 20 in outer glue-line 10, is avoided that in this way Cause resistance to increase with exterior part contact, and then transmission efficiency can be improved.

Further, the cross section of protrusions be Ω shape, be avoided that so raised interior thickness it is excessive lead to not it is curved It is bent.

Further, strand layer 20 is formed by silk group injecting glue, and wherein silk group is formed by least 5 silk thread twistings, this Sample can slow down silk thread to be reduced because corresponding to the integral strength of silk group position caused by abrasion.

Further, outer glue-line 10 with a thickness of 1 ~ 2mm, barrel shaped tooth layer 30 with a thickness of 1 ~ 2mm, both avoid in this way Thickness is too small cause intensity it is too low cannot run well and meanwhile also avoid it is blocked up cause weight excessive, increase unnecessary resistance.

Further, outer glue-line 10 and double wedge layer 30 are constituted using polythene material, can improve the effect of self-lubricating in this way Prolong the service life.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
