Abstract

The utility model provides a chain. The chain comprises a plurality of chain sections, an outer chain plate, a sleeve, hinge pins, a connecting chain plate, a connecting hinge pin, cotter pins, idler wheels, clamp springs and lengthened hinge pins. The multiple chain sections are movably connected through the outer chain plate and the hinge pins. The chain section located at the tail end is movably connected with the connecting hinge pin through the connecting chain plate and composed of two inner chain plates and two rollers. The lengthened hinge pins are sleeved with the sleeve. The two ends of the lengthened hinge pins stretch out of the sleeve. The two stretching ends of the lengthened hinge pins are sleeved with the idler wheels. The top ends of the two stretching ends of the lengthened hinge pins are sleeved with the clamp springs. The inner chain plates are connected with the two ends of the sleeve. The outer chain plate is connected with the two stretching ends of the lengthened hinge pins. Every two adjacent lengthened hinge pins are arranged at intervals of three hinge pins. The joint of one end of the connecting hinge pin and one end of the connecting chain plate and the joint of one end of the hinge pin in the chain section located at the tail end and the other end of the connecting chain plate are respectively provided with one cotter pin. By the adoption of the chain, transmission performance is enhanced, stability of the chain is improved, and the service life of the chain is prolonged.

Description

A kind of chain

Technical field

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

Background technique

Chain is as a kind of device of common driving force, the chain that mechanically transmission is used, " chain " design by 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 there is following defect in the chain using in the market: 1, conveyer chain running ability is poor; 2, in use easily come off.

Model utility content

The technical problems to be solved in the utility model is to overcome existing defect, and a kind of chain is provided, and has strengthened transmission performance, has improved the steadiness of chain, has extended the working life of chain.

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

A kind of chain, comprise some pitch chain joints, outer plate, sleeve, bearing pin, connection carrier bar, connect bearing pin and cotter pin, also comprise roller, jump ring and lengthening bearing pin, between some pitch chain joints, by outer plate, bearing pin, be flexibly connected, the links that is positioned at end is crossed connection carrier bar and is connected bearing pin flexible connection;

Chain link is comprised of two inner plates and two rollers;

In sleeve, be set with lengthening bearing pin, stretch out outside sleeve at the two ends that lengthen bearing pin, and the two ends of stretching out that lengthen bearing pin are arranged with roller, and the top of stretching out two ends that lengthens bearing pin is arranged with jump ring;

Inner plate is connected with sleeve two ends, and outer plate is connected with the two ends of stretching out that lengthen bearing pin;

Between between every two lengthening bearing pins, be separated with three bearing pins;

The one end that connects bearing pin is provided with cotter pin with the joint that is connected carrier bar one end, and the bearing pin one end that is arranged in the chain link of end is provided with cotter pin with the joint that is connected the carrier bar the other end.

Further, two rollers are positioned in the middle of two inner plates.

Further, two inner plates are horizontally disposed, and two rollers are vertically disposed.

Further, every two spacing that lengthen bearing pin are 600mm.

Further, the thickness of outer chain sheet and inner chain sheet is 8mm.

Further, the diameter of bearing pin is 19.85mm, and length is 80.3mm.

Further, the diameter of roller is 39.68mm.

Further, the length of connection bearing pin is 87.2mm.

Further, the inner width of two inner plates is 38mm.

A kind of chain of the utility model has increased roller on the basis of original chain, makes transmission performance stronger; Increased jump ring, can make chain more firm; Increased lengthening bearing pin, made chain more solid, increased the service life.

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:
