Description
Technical field
The utility model is related to tooth form variable velocity zone field, especially a kind of agricultural machinery tooth form variable velocity zone.
Background technology
Variable velocity zone is important part in speed changer, and variable velocity zone during work is because the driving between driving wheel and driven pulley is closed
System and stress cause double wedge and primer layer back-flexing stress increase in turn result in belt body stress transversely deforming, easily cause skidding
Phenomenon, reduces transmission efficiency.In addition when belt wheel is highly rotated, friction can produce high temperature, and radiating effect is poor, and wearability also becomes
Difference, physical life shortens.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of agricultural machinery tooth form variable velocity zone, solves belt body and laterally becomes
Shape, easily skids, and radiating effect is poor, the short problem of service life.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of agricultural machinery tooth form variable velocity zone, its
It is characterised by：Including top glue-line, cord ply, primer layer, double wedge and elastic force layer of cloth, the top glue-line is polymerized to one with primer layer
Body, the cord ply is wrapped in the place that is polymerized of top glue-line and primer layer；The primer layer has multiple double wedges, the double wedge
The flank of tooth by elastic force layer of cloth be bonded cover, the double wedge tooth top section for semicircle, two neighboring double wedge contact position arc transition；
The double wedge tooth top section is split into two tooth tops for semicircular small double wedge, and two described contact positions of small double wedge are in double wedge
The circle centre position arc transition in section.
Further technical scheme is that the top glue-line, primer layer and double wedge use ethylene propylene diene rubber.
Further technical scheme is that the top glue-line, primer layer and double wedge are used and uniformly divided in ethylene propylene diene rubber
Dissipate the complex that aramid fiber or polyester fiber are made.
Further technical scheme is that the cord ply uses some aramid fiber rigid lines or hard polyester line interval setting.
Further technical scheme is that the aramid fiber or polyester fiber are integrated with cord ply.
Further technical scheme is that the elastic force layer of cloth uses nylon66 fiber material.
It is using the beneficial effect produced by above-mentioned technical proposal：Top glue-line, primer layer and double wedge use ternary second
Third rubber and aramid fiber is added when it is kneaded, be driven belt higher intensity, with lateral stiffness higher and resistance to
Mill performance, makes belt be difficult to skid.The aramid fiber on cord ply can also be even utilized, it is dispersed in ethylene propylene diene rubber
Inside, sets two small double wedges at the tooth top of double wedge, make the stickiness of belt body and belt wheel more preferably, increased connecing for belt body and belt wheel
Contacting surface is accumulated, and increases frictional force, while the groove between two small double wedges can also radiate and enhance radiating effect, be increased and is used
Life-span.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the positive sectional view of the utility model；
Fig. 2 is the sectional view of the utility model side；
Wherein:1st, glue-line is pushed up；2nd, cord ply；3rd, primer layer；4th, double wedge；5th, small double wedge；6th, elastic force layer of cloth.
Specific embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new
Type can also be different from other manner described here using other be implemented, and those skilled in the art can be without prejudice to this reality
Similar popularization is done with the case of new intension, therefore the utility model is not limited by following public specific embodiment.
In the present embodiment shown in Fig. 1, Fig. 2 the utility model include top glue-line 1, cord ply 2, primer layer 3, double wedge 4,
Small double wedge 5, elastic force layer of cloth 6.
Cord ply 2 and primer layer 3 are sequentially provided with the glue-line 1 of top in the utility model, primer layer 3 has had multiple double wedges
4.Preferably, top glue-line 1 is polymerized with primer layer 3 and is integrated；Top glue-line 1, primer layer 3 and double wedge 4 use ethylene propylene diene rubber
It is made, or aramid fiber is added when it is kneaded, make belt that there is intensity higher, with lateral stiffness higher and resistance to
Mill performance, is unlikely to deform belt, is difficult to skid, and keeps transmission efficiency higher.Cord ply 2 using some aramid fiber rigid lines or
Hard polyester line interval setting；Which reduce the elongation of belt body, it is to avoid belt body elongation is skidded；Preferably, in ethylene propylene diene rubber
Aramid fiber and cord ply 2 be one overall, that is to say, that aramid fiber is to disperse out from cord ply；Each double wedge 4
Tip portion be equipped with two small double wedges 5, make the stickiness of belt body and belt wheel more preferably, increased the contact surface of belt body and belt wheel
Product, increases frictional force；The tooth top section of double wedge 4 is semicircle, the contact position arc transition of two neighboring double wedge 4；While two small
Groove is formd between double wedge 5 can also radiate, and enhance radiating effect, increased service life.In addition, the tooth top section of double wedge 4
Two tooth tops are split into for semicircular small double wedge 5, the circle centre position of described two contact positions of small double wedge in the section of double wedge 4 is justified
Arc transition.The flank of tooth of double wedge 4 and small double wedge 5 goes to orientation to be bonded with elastic force layer of cloth 6, and elastic force layer of cloth is preferentially using using nylon66 fiber material
Matter, increased the wearability of belt body, increased service life.
