Abstract
The invention relates to a big loading chain, which is formed by sequentially connecting chain links. Each chain link comprises an outer chain plate, an inner chain plate, a pin shaft, a sleeve and a roller, wherein two through holes are formed on each of the outer chain plate and the inner chain plate respectively and the outer chain plate and the inner chain plate are connected through the pin shaft; the sleeve is installed outside the pin shaft; and the roller is installed outside the sleeve. The big loading chain has the main technical characteristics as follows: the outer chain plate and the inner chain plate are chain plates provided with square through holes; the pin shaft is a chain pin shaft with a square head; and the square head of the chain pin shaft is fixedly inserted in each square through hole of the inner chain plate and the outer chain plate. The design is reasonable, and the chain is connected with the sleeve and the roller through the chain pin shaft with the square head and the chain plates with the square through holes, so that the pin shaft is prevented from jumping in the through hole of each chain plate, thereby improving the working stability of the chain; and the chain is also prevented from abrading the pin shaft at the same time, thereby prolonging the service life of the chain.
Description
Technical field
The invention belongs to field of chains, especially a kind of big load chain.
Background technique
Chain is the stronger engineering goods of a kind of versatility, because it has gear and belt concurrently, has therefore all obtained using widely at transmission, conveying and some special occasions.Chain is connected and composed by chain link usually successively; 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 through bearing pin, and sleeve is installed outside bearing pin, roller is installed outside sleeve realizes transmitting function.In existing big 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, need the rounded nose of bearing pin be inserted in the manhole of carrier bar and fixing, because big load chain in the course of the work; Bearing pin can produce play in manhole, therefore, and its less stable; Bearing pin rotation simultaneously can make carrier bar that bearing pin is produced to shear and cause bearing pin damaged, influenced the working life of chain.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, the big load chain of a kind of reasonable in design, stable performance and long service life is provided.
The present invention solves its technical problem and takes following technological scheme to realize:
A kind of big load chain; Connect and compose successively by chain link; Each chain link connects and composes by outer plate, inner plate, bearing pin, sleeve and roller, and outer plate and inner plate are equipped with two through holes and link together through bearing pin, and 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, and 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 square through hole and outer plate of inner plate and is fixing.
And described chain and chain-plate with square through hole comprises the carrier bar body, on the carrier bar body surface, is provided with two through holes, and a through hole is a manhole, and the another one through hole is a 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, on this square head portion, radially is shaped on a bearing pin through hole.
Advantage of the present invention and good effect are:
The present invention 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; Prevented bearing pin play in the carrier bar through hole effectively; Improved the stability of chain work, prevented the wearing and tearing of carrier bar simultaneously, the working life of having improved chain bearing pin.
Description of drawings
Fig. 1 is a structural drawing of the present invention;
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 present invention is done further detailed description:
A kind of big 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, and outer plate and inner plate are equipped with two through holes and link together through bearing pin; Sleeve is installed outside bearing pin, roller is installed outside sleeve realizes transmitting function.Innovation part of the present invention 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 square through hole and outer plate of inner plate; And in the bearing pin through hole, insert and pin and can inner plate, outer plate, sleeve, roller be linked together, be used with chain hinge pin through chain and chain-plate and can prevent bearing pin play in the carrier bar through hole effectively with square head portion with square through hole.Describe respectively in the face of the chain and chain-plate with square through hole, structure down 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, on the carrier bar body surface, is provided with two through holes, and a through hole is a manhole 6, and the another one through hole is a 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, on this square head portion, radially is shaped on a bearing pin through hole 10.
It is emphasized that; Embodiment of the present invention is illustrative; Rather than it is determinate; Therefore the present invention is not limited to the embodiment described in the embodiment, and every other mode of executions that drawn by those skilled in the art's technological scheme according to the present invention belong to the scope that the present invention protects equally.
