Abstract

The utility model provides a short pitch chain. A plurality of chain sections are divided into two parallel rows connected with each other. Adjacent chain sections in each row are connected through outer pieces on the two sides, the corresponding chain sections in the two rows are connected through hinge pins and middle pieces, the two chain sections at the tail end are movably connected with a connecting hinge pin through connecting chain pieces on the two sides, and each chain section is composed of two inner pieces and two rollers. One hinge pin is sleeved with two sleeves arranged on the two rows in parallel, wherein the two ends of the hinge pin extend out of the two sleeves, and the middle of the hinge pin penetrates through the two middle pieces. The two inner pieces of each chain section in two rows are connected with the two ends of the sleeves respectively, and the outer pieces on the two sides of each chain section in two rows are connected with the two extending ends of the corresponding hinge pin respectively. The position where one end of the hinge pin in one chain section at the tail end is connected with one end of one connecting chain piece is provided with a cotter pin, the position where one end of the connecting hinge pin is connected with the other end of the connecting chain piece is provided with a cotter pin, and the middle of the connecting hinge pin penetrates through the middle pieces. According to the short pitch chain, the strength of the rollers is improved, and the using strength of the chain is improved.

Description

A kind of short pitch chain

Technical field

The utility model relates to a kind of driving force device, specifically a kind of short pitch chain.

Background technique

Chain is as a kind of device of common driving force, and the chain that mechanically transmission is used, by " chain " design of hyperbolic bank, reduces friction, and is used in the larger and place that motion speed is slow of power, than belt transmission have obvious must superiority.This money chain belongs to heavy-load bending plate chain, is generally used on bench.

But the roller in the chain using is in the market frangible.

Model utility content

The technical problems to be solved in the utility model is to overcome existing defect, and a kind of short pitch chain is provided, and has improved the intensity of roller, the working life that has strengthened chain.

In order to solve the problems of the technologies described above, the utility model provides following technological scheme:

A kind of short pitch chain, comprise some pitch chain joints, outer plate, middle, bearing pin, sleeve, connection bearing pin, connection chain sheet and cotter pin, some pitch chain joints are divided into the interconnective chain link of two rows arranged side by side, between each row's adjacent link, by the outer plate of both sides, connect, between the upper corresponding chain link of two rows by bearing pin, middle connection, the connection chain sheet of the two pitch chains joints that are positioned at art end by both sides be connected bearing pin flexible connection;

Chain link is comprised of two interior sheets and two rollers;

In two sleeves that are set up in parallel on two rows, be set with a bearing pin, stretch out outside two sleeves at the two ends of bearing pin, and the middle part of bearing pin is through middle;

In two rows, two interior sheets of every shot of a cable joint are connected with sleeve two ends respectively, and the outer plate of both sides is connected with the two ends of stretching out of bearing pin respectively;

Be arranged in bearing pin one end of chain link of end and the joint of one end of connection chain sheet is provided with cotter pin, connect one end of bearing pin and be provided with cotter pin with the joint of the other end of connection chain sheet, the middle part that connects bearing pin is passed middle.

Further, two rollers are positioned in the middle of two sheets.

Further, two interior sheets are horizontally disposed, and two rollers are vertically disposed.

Further, the quantity of middle is 2, and 2 middle sheets are corresponding settings with outer plate.

Further, the material of roller is 40Cr.

A kind of short pitch chain of the utility model, the material of roller changes 40Cr into by original 10#, has improved the intensity of roller, has strengthened the working strength of chain.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
