Abstract
This utility model relates to a kind of without supporting auto-tensioning sprocket wheel, belongs to a kind of sprocket wheel.Connecting pin and connecting plate composition connecting joint, adjacent two chain toothed portions are connected with each other with connecting joint, gap is had between adjacent chain toothed portion, spring leaf is arranged in the mounting groove that adjacent two chain toothed portions and body part are formed, spring leaf is evenly distributed on body part external peripheral surface, body part support chain toothed portion and spring leaf.Advantage is novel structure, under same Chain conveyer operating mode, compared to existing chain drive system tensioner, simplifies tensioning device structure, thus simplifies the structure of chain drive system, makes chain drive system be taken up space reduction；Simultaneously at structure, limited space, using under limited operating mode compared to existing tensioner, this utility model device could be used that.
Description
Technical field
This utility model relates to a kind of sprocket wheel, and more particularly, to one without support means and by tensioning chain
Wheel changes own form and realizes the tightener sprocket structure of auto-tensioning.
Background technology
Existing tightener sprocket is arranged in support shaft, and by carrying out tensioning worn chain with chain contact.Existing tensioning
The sprocket wheel tensioning mode to worn chain, it is common that realize the tensioning to chain by changing the physical location of tightener sprocket.
But existing tightener sprocket needs to be arranged in support shaft, it is desirable to have oneself auxiliary support device a set of so that whole chain passes
The structure of dynamic system becomes big, and the change that taken up space is big, while structure, limited space chain drive system in, existing Chain conveyer
Tensioner uses limited.
Summary of the invention
This utility model provides a kind of without supporting auto-tensioning sprocket wheel, and it has simplification tensioning device structure, and has applicable
In structure, the advantage of the chain drive system of limited space.
This utility model adopts the technical scheme that, connecting pin and connecting plate composition connecting joint, adjacent two chain toothed portions with
Connecting joint is connected with each other, and has gap, spring leaf to be arranged on adjacent two chain toothed portions and body part between adjacent chain toothed portion
In the mounting groove formed, spring leaf is evenly distributed on body part external peripheral surface, body part support chain toothed portion and bullet
Reed.
Spring leaf described in the utility model is made up of spring steel.
This utility model mounting groove shape is corresponding to the shape of spring leaf.
This utility model body part is hollow.
The utility model has the advantages that novel structure, under same Chain conveyer operating mode, compared to existing chain drive system
Tensioner, simplifies tensioning device structure, thus simplifies the structure of chain drive system, make chain drive system be taken up space and subtract
Little；Simultaneously at structure, limited space, using under limited operating mode compared to existing tensioner, this utility model device also can
Use.

Detailed description of the invention
Of the present utility model each embodiment is described more detail below, shows this with in description below in the accompanying drawings
The example of a little embodiments.Although this utility model will combine with exemplary and be described, but it should be appreciated that
Arriving, this specification is not intended to be limited to this utility model those exemplary.On the contrary, this utility model is intended to not
But cover these exemplary, and cover and can be included in this utility model being defined by the appended claims
Spirit and scope within various replacements, amendment, equivalents and other embodiments.
Hereinafter with reference to appended accompanying drawing, this utility model is described more comprehensively, show this in the drawings
The exemplary of utility model.
Exemplary is example of the present utility model and those skilled in the art can be carried out in every way
Amendment, so scope of the present utility model is not limited to exemplary of the present utility model described below.
Running through this specification, unless otherwise expressly, " including " any assembly will be understood as one that and means to include other
Assembly rather than discharge any other assembly.Additionally, the name of assembly is not intended to its function.
Fig. 2 is to illustrate the axonometric chart without supporting auto-tensioning sprocket wheel according to exemplary of the present utility model.
With reference to Fig. 2, support auto-tensioning sprocket wheel according to the nothing of exemplary of the present utility model and there is chain teeth portion
Point 1, spring leaf 2, body part 3, connecting pin 4, connecting plate 5；
Connecting pin 4 and connecting plate 5 form connecting joint, and adjacent two chain toothed portions 1 are connected with each other with connecting joint, adjacent sprocket
Gap 6, spring leaf 2 is had to be arranged in the mounting groove that adjacent two chain toothed portions 1 and body part 3 are formed between part, bullet
Reed is evenly distributed on the external peripheral surface of body part 3, body part 3 support chain toothed portion 1 and spring leaf 2；
Spring leaf 2 is made up of spring steel；
Spring leaf mounting groove shape is corresponding to the shape of spring leaf；
Body part 3 is hollow.
Operation principle, with reference to Fig. 1.
Being placed between two chains without supporting auto-tensioning sprocket wheel, sprocket is meshed with chain, and lower end chain supports this
Tight sprocket wheel, tightener sprocket pressurized during installation, tightener sprocket is become oval from circle, and after chain wear, chain length extends,
Tight sprocket wheel pressure reduces, and sprocketed wheel shape gradually reverts to circle, reaches the effect of auto-tensioning.
