Description

A kind of transmission belt for automatically-controlled door

Technical field

The utility model belongs to transmission belt technical field, more particularly, to a kind of transmission belt for automatically-controlled door.

Background technique

Existing transmission is integrally formed the low easy fracture of its intensity with rubber, causes efficiency to reduce, and rubber and gear Directly contact easily causes abrasion, causes service life short, causes increased costs, it is therefore necessary to be 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 transmission for automatically-controlled door Band, it has, and structure simple strength is high, wear-resistant, the characteristics of prolonging the service life.

To achieve the goals above, the technical scheme adopted by the utility model is a kind of transmission belt for automatically-controlled door, Including band body, the band body successively includes first layer, steel wire floor, the second layer and braiding layer, the second layer and volume from outside to inside Double wedge is equipped between tissue layer, the steel wire floor is formed by steel wire group injecting glue, the first layer, steel wire floor, the second layer and double wedge one It is body formed.

Further, the steel wire group is formed by least 5 steel wire twistings.

Further, the braiding layer is woven by warp and weft are interlaced.

Further, the warp is formed by least 2 silk thread twistings, and the weft is formed by least 2 silk thread twistings.

Further, the cross section of the double wedge is half elliptic.

Further, the braiding layer is fixedly linked by glue and double wedge.

Further, the thickness of the first layer and the second layer is 1 ~ 2mm.

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

1. the utility model be equipped with anti-skidding steel wire floor and steel wire floor the steel wire group injecting glue as made of at least 5 steel wire twistings and At can improve whole intensity and prolong the service life.

2. the braiding layer of the utility model is covered on double wedge is avoided that double wedge is directly in contact and then subtracts with gear in this way The abrasion of slow double wedge prolongs the service life.

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

Fig. 3 is the enlarged diagram of the utility model part A.

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. 3: a kind of transmission belt for automatically-controlled door, including band body, it is characterised in that: wherein Band body includes successively from outside to inside first layer 10, steel wire floor 20, the second layer 30 and braiding layer 40, in the second layer 30 and braiding layer 40 Between be equipped with double wedge 50, wherein steel wire floor 20 is formed by 21 injecting glue of steel wire group, wherein first layer 10, steel wire floor 20, the second layer 30 It is integrally formed with double wedge 50, whole intensity can be improved using the above structure and prolonged the service life, wherein braiding layer 40 covers It is avoided that double wedge 50 is directly in contact with gear and slows down the abrasion of double wedge 50 in turn and prolong the service life in this way on double wedge 50.

Further, wherein steel wire group 21 is formed the intensity that can improve steel wire floor 20, Jin Erti by least 5 steel wire twistings High whole intensity.

Further, wherein braiding layer 40 is by warp 41 and weft 42 is interlaced weaves, and middle longitude 41 is by extremely Few 2 silk thread twistings form, and equator 42 is formed by least 2 silk thread twistings, and the wearability that can improve braiding layer 40 extends Service life.

Further, the cross section of double wedge 50 is half elliptic, can make excessively more gentle, raising transmission effect in this way Rate.

Further, braiding layer 40 is fixedly linked by glue and double wedge.

Further, the thickness of first layer 10 and the second layer 30 is 1 ~ 2mm, both avoided in this way thickness it is too small cause it is strong Spend it is low cannot run well and meanwhile also avoid it is blocked up cause weight excessive, increase unnecessary resistance.

Further, it is covered with outlier 60 far from the side of steel wire floor 20 in first layer 10, wherein the surface of outlier 60 It is smooth in avoid impurity fall be attached to above cause to increase unnecessary resistance, thus achieve the effect that improve working efficiency.

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.
