Embodiment

Be described in detail to the utility model below in conjunction with drawings and Examples, it should be noted that in the following description content, similar element represents with identical numbering.

Consult Fig. 2, Fig. 3 and Fig. 4, first embodiment of the utility model high-test chain comprises several inner chain sheet unit 2, several outer chain sheet unit 3 be separately positioned on outside described inner chain sheet unit 2, and several concatenation unit 4 being connected in series described inner chain sheet unit 2 and described outer chain sheet unit 3 respectively.Following content, will carry out aid illustration by defining a first direction A1 and second direction A2 perpendicular to one another.

Described inner chain sheet unit 2 is respectively along this first direction A1 spaced-apart relation.Each inner chain sheet unit 2 comprises and is spaced two relative inner chain sheets 21 along this second direction A2.Each inner chain sheet 21 generally in 8-shaped, and comprise four layers make with metal respectively and superimposed each other in lamella 211.The described interior lamella 211 of each inner chain sheet 21 matches to define in one first interior perforation 212 and one second and bores a hole 213.

Described outer chain sheet unit 3 comprises two outer chain sheets 31 respectively.Between each outer chain sheet 31 is positioned at outside adjacent two the described inner chain sheets 21 of this first direction A1, generally in 8-shaped, and comprise four layers and make with metal respectively and outer lamella 311 superimposed each other.The described outer lamella 311 of each outer chain sheet 31 matches and defines in one and corresponding first first of 212 coaxial communication of bore a hole and outer bore a hole 312, and second of one and the corresponding second interior 213 coaxial communication of boring a hole bores a hole 313 outward.

The elements such as described concatenation unit 4 can comprise chain rivet respectively, chain rolls, roller, because the method described inner chain sheet 21 and described outer chain sheet 31 are serially connected is conventional art, therefore, in this description will be omitted.

Generally speaking, as having lattice imperfection, then the metallic atom of this metallic material in metallic material, can hinder because being subject to lattice imperfection, and not easily poor row be mobile each other, and make this metallic material can have higher intensity.

Namely the utility model is utilize aforementioned principles dexterously: making described inner chain sheet 21 with the process of described outer chain sheet 31, several metal bullets can be utilized to impact described interior lamella 211 respectively with described outer lamella 311 to carry out surface treatment, namely Shot Blasting in the past, therefore described interior lamella 211 and described outer lamella 311 have the surface of Shot Blasting.When Shot Blasting, the metallic atom of described interior lamella 211 and described outer lamella 311, understand uneven displacement because being subject to uneven impact power, therefore described interior lamella 211 understands because having lattice imperfection storage surface pressure with described outer lamella 311.Described inner chain sheet 21 has the design of described interior lamella 211 respectively, and described outer chain sheet 31 has the design of described outer lamella 311 respectively, each inner chain sheet 21 and each outer chain sheet 31 can be made compared to the chain sheet of monolayer constructions will in the past, accumulation has higher surface pressure, and thus has higher fatigue strength.

Therefore, effect of the present utility model is: described interior lamella 211 can accumulate surface pressure when Shot Blasting respectively with described outer lamella 311, make described inner chain sheet 21 can obtain the surface pressure of higher total amount with described outer chain sheet 31 and promote fatigue strength, because the described inner chain sheet 21 of the utility model high-test chain by high-fatigue strength is formed with described outer chain sheet 31, therefore there is higher fatigue strength equally, and can the purpose of this utility model be reached.

In the present first embodiment, described interior lamella 211 is identical with the structure of described outer lamella 311, and thickness T1 is respectively 0.8mm, makes described inner chain sheet 21 be respectively 3.2mm with the thickness T2 of described outer chain sheet 31.

The thickness T1 of described interior the lamella 211 and thickness T1 of described outer lamella 311, according to the difference of use occasion, 0.15mm can also be respectively, 0.1875mm, 0.275mm, 0.35mm, 0.375mm, 0.425mm, 0.45mm, 0.75mm, 0.875mm, 1.0mm, 1.125mm, 1.25mm, 1.5mm, 1.6mm, 1.75mm, 1.85mm, 2mm, 2.125mm, 2.375mm, and 3mm, and make the thickness T2 of described the inner chain sheet 21 and thickness T2 of described outer chain sheet 31 be respectively 0.60mm, 0.75mm, 1.10mm, 1.40mm, 1.50mm, 1.70mm, 1.80mm, 3.0mm, 3.50mm, 4.0mm, 4.50mm, 5.0mm, 6.0mm, 6.40mm, 7.0mm, 7.40mm, 8.0mm, 8.50mm, 9.50mm, 12.0mm.

It should be noted that, principle of the present utility model is that the surface pressure utilizing the single chain sheet of raising to have is to improve the fatigue strength of single chain sheet, therefore each inner chain sheet 21 and each outer chain sheet 31 only will comprise several described interior lamellas 211 and described outer lamella 311 just enough respectively, quantitatively without the need to being particularly limited to.That is, each inner chain sheet 21 is not limited with the described interior lamella 211 with four layers, and each inner chain sheet 21 also can have two-layer, more than three layers or five layers described interior lamella 211 on the implementation.Similarly, each outer chain sheet 31 is not limited with the described outer lamella 311 with four layers, and each outer chain sheet 31 also can have two-layer, more than three layers or five layers described outer lamella 311 on the implementation.Under the prerequisite that described inner chain sheet 21 is fixing with the thickness of described outer chain sheet 31, lamella 211 can be thicker with the thickness of each outer lamella 311 in each for two-layer design liaison, that is in each lamella 211 and each outer lamella 311 independent process process time stability better; Although the design of four layers represents lamella 211 and the thinner thickness of each outer lamella 311 in each, described inner chain sheet 21 structure more two-layer with described outer chain sheet 31 can be made to accumulate more surface pressure, and there is higher fatigue strength, respectively have advantage.

In addition, the design that in described in this first embodiment, the thickness T1 of lamella 211 is identical with described outer lamella 311 thickness T1, there is the advantage of saving die sinking cost, but not as limit in enforcement, that is described interior lamella 211 thickness T1 to each other, described outer lamella 311 thickness T1 to each other, and described interior lamella 211 also can be different from described outer lamella 311 thickness T1 to each other, and make described inner chain sheet 21 thickness T2 to each other, described outer chain sheet 31 thickness T2 to each other, and described inner chain sheet 21 also can be different from described outer chain sheet 31 thickness T2 to each other, do not disclose with this first embodiment and be limited.

Consult Fig. 5, second embodiment and this first embodiment of the utility model high-test chain are similar, and different places is that described inner chain sheet 21 is different from the profile of described outer chain sheet 31.Described inner chain sheet 21 omits the recessed waist of ecto-entad with described outer chain sheet 31 and designs, and is a kind of chain sheet of straight kidney-shaped.Because described inner chain sheet 21 and described outer chain sheet 31 also all have the structure of four layers, high surfaces pressure can be accumulated equally and preferably fatigue strength can be had, therefore the object that the utility model provides the chain that a kind of fatigue strength is higher can be reached equally.
