Abstract
The utility model relates to a sleeve sealed chain, which is characterized in that: hinge holes are arranged at both ends of a pair of inner chain plates; a sleeve is arranged on the hinge holes of the inner chain plate; a roller is movably arranged on the sleeve; a pin shaft is movably arranged in the sleeve; a pair of outer chain plates are arranged at both ends of the pin shaft. Concentric ring grooves are arranged at two side ends of the sleeve; an O-shaped seal ring is installed in the ring groove; through the O-shaped seal ring, loose materials are stopped from entering the clearance between the sleeve and the pin shaft through the part between the inner chain plate and the outer chain plate, the rotating of the inner/outer chain plates is ensured to be flexible, meanwhile, the wear and tear between the sleeve and the pin shaft is avoided, and the service life of a conveying chain is prolonged. Additionally, the sleeve sealed chain has advantages of simple structure and easy manufacturing.
Description
Technical field
The utility model relates to a kind of chain, especially a kind of sleeve seal chain.
Background technology
Chain generally is used for the conveyer of mine, the loading and unloading of harbour granule materials.Known chain structure is: a pair of inner plate two ends are shaped on hinge hole, on two inner plate hinge holes sleeve are installed, and are movably installed with roller on sleeve, are movably installed with bearing pin in sleeve, at the bearing pin two ends a pair of pin link plate are installed.This chain is in the casing chain load transfer device of carrying bulk material, chain rolls in orbit and advances in level, vertical, heeling condition, especially under the perpendicular movement situation, chain relative transposition of pin link plate in the sprocket wheel turning is returned, and pin link plate should rotate flexibly in it.In case when bulk material entered space between sleeve and the bearing pin between interior pin link plate, pin link plate rotated dumbly in will causing, and even rotates, this moment, pin link plate and bearing pin rotated, and then wear damage.When chain was carried the mill material that chiseling property is strong or viscosity is strong, above-mentioned friction was more violent, causes bearing pin, sleeve wear damage at short notice, causes chain not use, thereby needed to shut down maintenance.This not only makes, and operating cost increases greatly, the equipment operation rate descends, and enterprise's production has been caused considerable influence.
Summary of the invention
The utility model provides a kind of material worn-down sleeve seal chain of avoiding for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of sleeve seal chain, comprise that two ends are shaped on a pair of inner plate of hinge hole, are installed in sleeve on the inner plate hinge hole, are movably arranged on roller on the sleeve, are movably arranged on bearing pin in the sleeve and a pair of pin link plate that is installed in the bearing pin two ends, described sleeve two side ends is shaped on concentric annular groove, and the O RunddichtringO is installed in the annular groove.
The utility model can also adopt following technical scheme:
The cross section of described annular groove is rectangular.
The cross section of described annular groove is V-shaped.
Advantage and the good effect that the utlity model has are:
Owing to be shaped on concentric annular groove in the sleeve two side ends, the O RunddichtringO is installed in the annular groove, has stoped bulk material from entering the space between sleeve and the bearing pin between the interior pin link plate, pin link plate rotates flexibly in guaranteeing, avoid the wearing and tearing of sleeve and bearing pin, prolonged chain service life; The utility model also has advantage simple in structure, that be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the another kind of constructional drawing of sleeve annular groove.
Among the figure: 1, bearing pin; 2, sleeve; 3, roller; 4, inner plate; 5, pin link plate; 6, annular groove; 7, O RunddichtringO; 8, sleeve; 9, annular groove.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, a pair of inner plate 4 two ends are shaped on hinge hole, and sleeve 2 is installed on the inner plate hinge hole, are movably installed with roller 3 on sleeve, are movably installed with bearing pin 1 in sleeve, and a pair of pin link plate 5 is installed at the bearing pin two ends.Described sleeve two side ends is shaped on concentric annular groove 6, and the cross section of this annular groove is rectangular, and O RunddichtringO 7 is installed in the annular groove.Annular groove also can be made into the V-shaped annular groove in cross section 9 in addition, and shown in the sleeve among Fig. 28, its sealing effectiveness is identical.Like this, owing to be shaped on concentric annular groove, the O RunddichtringO is installed in the annular groove in the sleeve two side ends, stoped bulk material from entering the space between sleeve and the bearing pin between the interior pin link plate, pin link plate rotates flexibly in guaranteeing, has avoided the wearing and tearing of sleeve and bearing pin, has prolonged chain service life; The utility model also has advantage simple in structure, that be easy to make in addition.
