The dust-proof chain of hinge is the extraordinary chain of one on a kind of load transfer device.Be widely used in the mass transport in metallurgy, mine, harbour, building materials, power plant's heating power, grain and oil, food processing process.
Chain of the prior art be by the assemblies such as multiple inner link and outer link with the form of hinges couple together around property part, Fig. 1 and Fig. 2 is respectively the structural representation of inner link of the prior art and outer link.Wherein Fig. 1 inner link 7 comprises the first inner plate 11, second inner plate 12, sleeve 2 and roller 3; Fig. 2 outer link 8 comprises the first pin link plate 41, second pin link plate 42 and bearing pin 6.In order to the alerting ability of hinge will be guaranteed, inner plate and pin link plate, between sleeve and bearing pin, gap must be designed with.Therefore, by the gap formed between inner plate, pin link plate, in some foreign particles can be allowed to enter hinges that sleeve and bearing pin form, thus make the service life of its wear and tear increase, shortening chains.
Summary of the invention
In order to the wearing and tearing overcoming the dust-proof chain of existing hinge are comparatively large, service life shorter deficiency, the dust-proof chain of hinge that the utility model provides a kind of and reduces wear, increases the service life.
The utility model solves the technical scheme that its technical matters adopts:
The dust-proof chain of a kind of hinge, comprise inner link and outer link, described inner link is connected with hinges form with described outer link, and described inner link comprises inner plate, sleeve and roller, and described inner plate comprises the first inner plate and the second inner plate; Described outer link comprises pin link plate and bearing pin, and described pin link plate comprises the first pin link plate and the second pin link plate; Described sleeve is through the endoporus of described roller, the two ends of described sleeve are arranged on described first inner plate and described second inner plate respectively, described bearing pin is successively through the first pin link plate, sleeve and the second pin link plate, described dust-proof chain also comprises dustproof construction, described dustproof construction comprises dust-proof cushion, described dust-proof cushion is provided with between described first inner plate and described first pin link plate, between described second inner plate and described second pin link plate, described dust-proof cushion is annular dust-proof cushion, and described annular dust-proof cushion is sleeved on described sleeve.
Further, described dustproof construction also comprises O RunddichtringO, contacts described inner plate side and has the first ring connected in star of opening towards described inner plate, be provided with described O RunddichtringO in described first ring connected in star at described annular dust-proof cushion.
Further again, described dustproof construction also comprises V-shaped seal ring, contacts described pin link plate side and has second annular groove of opening towards described pin link plate, be provided with described V-shaped seal ring in described second annular groove at described annular dust-proof cushion.
The beneficial effects of the utility model are mainly manifested in: the dust-proof conveyer chain of hinge has installed dustproof construction in inner link and outer link contacts side surfaces district, thus make foreign matters from the sideshake between inner plate and pin link plate, enter the hinges of sleeve and bearing pin, to reach the object that reduces wear, extend the service life of chain.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing inner link.
Fig. 2 is the structural representation of existing outer link.
Fig. 3 is the structural representation of the dust-proof chain of hinge.
Fig. 4 is the enlarged drawing in A portion in Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1 ~ Fig. 4, the dust-proof chain of a kind of hinge, comprise inner link 7 and outer link 8, described inner link 7 is connected with hinges form with described outer link 8, described inner link 7 comprises inner plate, sleeve 2 and roller 3, and described inner plate comprises the first inner plate 11 and the second inner plate 12, described outer link 8 comprises pin link plate and bearing pin 6, and described pin link plate comprises the first pin link plate 41 and the second pin link plate 42, described sleeve 2 is through the endoporus of described roller 3, the two ends of described sleeve 2 are arranged on described first inner plate 11 and described second inner plate 12 respectively, described bearing pin 6 is successively through the first pin link plate 41, sleeve 2 and the second pin link plate 42, described dust-proof chain also comprises dustproof construction, described dustproof construction comprises dust-proof cushion 9, between described first inner plate 11 and described first pin link plate 41, described dust-proof cushion 9 is provided with between described second inner plate 12 and described second pin link plate 42, described dust-proof cushion 9 is annular dust-proof cushion, described annular dust-proof cushion is sleeved on described sleeve 2.
Further, described dustproof construction also comprises O RunddichtringO 21, contacts described inner plate side and has the first ring connected in star of opening towards described inner plate, be provided with described O RunddichtringO 21 in described first ring connected in star at described annular dust-proof cushion.
Further again, described dustproof construction also comprises V-shaped seal ring 10, contacts described pin link plate side and has second annular groove of opening towards described pin link plate, be provided with described V-shaped seal ring 10 in described second annular groove at described annular dust-proof cushion.
