Abstract
The utility model relates to a novel large load chain. Chain links are connected in sequence to constitute the novel large load chain, each link is composed of an outer chain plate, an inner chain plate, a pin shaft, a sleeve and a roller in connected mode, each outer chain plate and each inner chain plate are respectively provided with two through holes, each outer chain plate is connected with each inner chain plate through each pin shaft, each sleeve is installed outside each pin shaft, and each roller is installed outside each sleeve. The novel large load chain is characterized in that the outer chain plates and the inner chain plates are both link chain plates which are provided with the square through holes, the pin shafts are chain pin shafts provided with square head portions, and the square head portions of the chain pin shafts are installed inside the square through holes of the inner chain plates and inside the square through holes of the outer chain plates in inserted mode and are fixed. The novel large load chain is reasonable in design, the chain pin shafts provided with the square head portions and the link chain plates provided with the square through holes are connected with the sleeves and the rollers, the pin shafts are effectively prevented from shifting inside the through holes in the chain plates, work stability of the chain is improved, the chain plates are prevented from abrading the pin shafts simultaneously, and service life of the chain is prolonged.
Description
Technical field
The utility model belongs to field of chains, especially a kind of novel large load chain.
Background technique
Chain is the stronger engineering goods of a kind of versatility, because it has gear and belt concurrently, therefore all is widely used at transmission, conveying and some special occasions.Chain is connected and composed successively by chain link usually, each chain link connects and composes by outer plate, inner plate, bearing pin, roller, sleeve, outer plate and inner plate are equipped with through hole and link together by bearing pin, and sleeve is installed outside bearing pin, be provided with roller and realize transmitting function between inner plate.In existing large load chain structure, the through hole that common carrier bar is provided with is circle, and corresponding bearing pin head also is circular, when installing and using, the rounded nose of bearing pin need to be inserted in the manhole of carrier bar and fixing, because large load chain in the course of the work, bearing pin can produce play in manhole, therefore, and its less stable, simultaneously bearing pin rotation meeting causes bearing pin damaged so that carrier bar produces to shear to bearing pin, has affected the working life of chain.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the novel large load chain of a kind of reasonable in design, stable performance and long service life is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of novel large load chain, connected and composed successively by chain link, each chain link connects and composes by outer plate, inner plate, bearing pin, sleeve and roller, outer plate and inner plate are equipped with two through holes and link together by bearing pin, sleeve is installed outside bearing pin, roller is installed outside sleeve, described outer plate, inner plate are the chain and chain-plate with square through hole, bearing pin is the chain hinge pin with square head portion, and the square head portion of chain hinge pin is inserted in the square through hole of the square through hole of inner plate and outer plate and is fixing.
And described chain and chain-plate with square through hole comprises the carrier bar body, is provided with two through holes at the carrier bar body surface, and a through hole is manhole, and the another one through hole is square through hole.
And described chain hinge pin with square head portion comprises the bearing pin body, is provided with the bottom at bearing pin body one end, is provided with at the other end of bearing pin body and is shaped as square head, radially is shaped with a bearing pin through hole on this square head.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, the chain hinge pin that use has square head portion links together itself and sleeve, roller with the chain and chain-plate with square through hole, effectively prevented bearing pin play in the carrier bar through hole, improved the stability of chain work, the wearing and tearing of carrier bar to bearing pin have been prevented simultaneously, the working life of having improved chain.
Description of drawings
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is the chain and chain-plate structural representation with square through hole;
Fig. 3 is the chain hinge pin structural representation with square head portion;
Fig. 4 is that the A of Fig. 3 is to view.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of novel large load chain, as shown in Figure 1, connected and composed successively by chain link, each chain link connects and composes by outer plate 1, inner plate 2, bearing pin 3, sleeve 4 and roller 5, outer plate and inner plate are equipped with two through holes and link together by bearing pin, sleeve is installed outside bearing pin, between inner plate, is provided with roller and realizes transmitting function.Innovation of the present utility model is: outer plate, inner plate are the chain and chain-plate with square through hole, bearing pin is the chain hinge pin with square head portion, in use, the square head portion of chain hinge pin is inserted in the square through hole of the square through hole of inner plate and outer plate, and the insertion pin can link together inner plate, outer plate, sleeve, roller in the bearing pin through hole, is used in conjunction with the chain hinge pin with square head portion by the chain and chain-plate with square through hole and can effectively prevents bearing pin play in the carrier bar through hole.The below describes respectively the chain and chain-plate with square through hole, the structure with chain hinge pin of square head portion.
As shown in Figure 2, the chain and chain-plate with square through hole comprises carrier bar body 1, is provided with two through holes at the carrier bar body surface, and a through hole is manhole 6, and the another one through hole is square through hole 7.
As shown in Figure 3, the chain hinge pin with square head portion comprises bearing pin body 3, is provided with bottom 8 at bearing pin body one end, is provided with at the other end of bearing pin body and is shaped as square head 9, radially is shaped with a bearing pin through hole 10 on this square head.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other mode of executions that the technical solution of the utility model draws, belong to equally the scope of the utility model protection.
