Abstract
The present invention relates to a structure of a chain gear, an inner seat and an outer chain seat of the structure are connected together through an inner chain hole and an outer chain hole which are respectively arranged on the inner chain seat and the outer chain seat by a chain pin and a chain cover. The inner chain seat is composed of an inner chain sheet which is connected in a bridge connection mode between two inner chain sheets; the outer chain seat is composed of an outer chain bridge which is connected in a bridge connection mode between two outer chain sheets; one end of the inner chain sheets and the outer chain sheets is convex or forms in a circular arc shape. The arranged chain gear is combined into a chain, since the inner and the outer chain sheets are provided with the structure of the chain bridge, asymmetry arrangement is displayed. Thus, when the chain drives, mutual retardation action is generated between the inner chain bridge and the outer chain bridge, rotation restriction is generated between the inner and the outer chain sheets, making the chain to have certain directionality when drives. If restricted directionally, the inner and the outer chain sheets are caused to have ordered arrangement along one direction. The ordered arrangement has wide usage in the field of the mechanical transmission.
Description
Technical field
The present invention relates to mechanical transmission fields, perhaps transmission field of tool especially refers to a kind of structure of sprocket of chain.
Background technique
Chain has a wide range of applications in mechanical transmission fields, existing chain is interconnected by a plurality of sprockets according to purposes and transmission requirement and forms, each sprocket then is made of by chain pin and the chain case that is socketed on the chain pin sprocket inner chain sheet and outer chain sheet, and chain pin and chain case make up chaining with sprocket; This chain can only could normally use with gear engagement under the situation of tensioning, otherwise promptly can take off chain and can't use, because this chain is under non-tensioning state, the angle of sprocket and the misfit of chain between cog can be the positive negative angle of symmetry, be a kind of unordered arrangement, do not have the function of directed transmission; And the chain with directed transmission agency patent and market survey are found as yet by retrieval.
Summary of the invention
The structure of sprocket that the purpose of this invention is to provide a kind of chain of orientable transmission also claims a kind of structure of sprocket.
Technological scheme of the present invention is achieved in that
A kind of structure of sprocket is provided, comprises chain pin and chain case socket join structure, its inner chain seat and outer chain seat connect and compose with described chain pin and chain case by interior chain hole and the outer chain hole that is provided with respectively on it; Described inner chain seat is made of cross-over connection inner chain bridge between two inner chain sheets; Described outer chain seat is made of the outer chain bridge of cross-over connection between two outer chain sheets.
Two inner chain sheets and inner chain bridge on the aforesaid inner chain seat are connected as a single entity; Two outer chain sheets on the outer chain seat are connected as a single entity with outer chain bridge.
One end of aforesaid inner chain sheet and an end of outer chain sheet projection or be circular arc.
Through more than behind the sprocket combination chaining after being provided with, owing on interior outer chain sheet, be provided with the structure of chain bridge, and present a kind of asymmetry setting, thereby during transmission, produce mutual retardation between inner chain bridge and the outer chain bridge, inside and outside chain sheet produces the turn constraint each other, and makes chain have certain directivity when transmission, if in addition directed constraint then can make it along a direction to be orderly arrangement; This mechanical transmission fields that is ordered in has purposes widely.

Fig. 2 is that critical piece of the present invention splits structural drawing;
Fig. 3 is the three-dimensional structure diagram of a kind of chain three sprockets commonly used on the market;
Fig. 4 is user mode figure of the present invention;
Fig. 5 is that mould pulls and pushes the part-structure figure after core adopts the present invention.
Embodiment
Below in conjunction with the description of drawings embodiments of the invention:
Referring to Fig. 3, provide the structure of a kind of chain common on the market, its sprocket is made of by chain pin 1 and the chain case 2 that is socketed on the chain pin 1 inner chain sheet 7 and outer chain sheet 8, and chain pin 1 and chain case 2 make up chaining with sprocket; This chain can only could normally use with gear engagement under the situation of tensioning, otherwise promptly can take off chain and can't use, because this chain is under non-tensioning state, the angle of sprocket and the misfit of chain between cog can be the positive negative angle of symmetry, be a kind of unordered arrangement, do not have the function of directed transmission.
Referring to Fig. 1, provide a kind of embodiment of the present invention, it comprises chain pin 1 and chain case 2 socket join structures, its inner chain seat 3 and outer chain seat 4 connect and compose by the interior chain hole 5 that is provided with respectively on it and the described chain pin 1 of outer chain hole 6 usefulness and chain case 2; Cross-over connection has inner chain bridge 9 between two inner chain sheets 7.Cross-over connection has outer chain bridge 10 between two outer chain sheets 8; During production, two inner chain sheets 7 on the inner chain seat 3 are connected as a single entity with inner chain bridge 9; Two outer chain sheets 8 on the outer chain seat 4 are connected as a single entity with outer chain bridge 10.
In the foregoing description, an end of inner chain sheet 7 and an end of outer chain sheet 8 can be arranged to circular arc or projection, all not influence the present invention's function.
Referring to Fig. 5, be the part-structure of a kind of embodiment behind mould employing the present invention; With the chain that the present invention makes, by the core of gear driven mould, the structure of a kind of chain external that shows among Fig. 5 is applied on the mould, and during die sinking, chain changes the direction composition at a plurality of flex points place of die surface setting and finishes the process of loosing core to motion; During matched moulds, chain is the driven gear work of straight chain shape and finishes the lock pin process under the mutual constraint of sprocket.
Another kind of embodiment is provided, the structure that a kind of chain is built-in, chain is extended in the mold, when chain is loosed core, chain is pulled out in mould, and during lock pin, chain is under the mutual constraint of sprocket, be the driven gear work of straight chain shape and finish the lock pin process, reciprocating action, and finish process of producing product.
The essence that the design of the structure of outer chain bridge and interior outer chain sheet is the present invention within on the shape of the present invention's sprocket, the sprocket is wanted, and belongs to the emphasis of the present invention's protection.
The present invention makes of common metal such as stainless steel and gets final product.
