Abstract

The invention relates to a transmission chain which comprises a plurality of outer chain plates and a plurality of inner chain plates. The outer chain plates and the inner chain plates are opposite pairwise. Shaft holes are formed in the two ends of each outer chain plate and the two ends of each inner chain plate respectively. Chain shafts penetrate into the shaft holes to enable the adjacent outer chain plates and inner chain plates to be connected together. The chain shafts are sleeved with shaft sleeves. Stress planes are arranged at the tops of the outer chain plates and the tops of the inner chain plates respectively. Shear force borne by chain shafts of an existing chain for transmitting thrust is large, and consequently the chain shafts and chain plates are prone to being abraded. The transmission chain is adopted and has the advantages that shearing force borne by the chain shafts is small, abrasion to the chain shafts and the chain plates is small, and thrust can be transmitted; and the service life is long, and the transmitting precision is high.

Description

A kind of drive chain

Technical field

The invention belongs to transmission device field, be specifically related to a kind of drive chain.

Background technique

In the spentnuclear fuel equipment for after-treatment of nuclear power station, because certain advantage of open type chain, the structural type transmitting thrust of open type chain need be utilized, and normally used drive chain is mainly used in bearing pulling force, and the load between each carrier bar is mainly born by chain rivet, this makes chain rivet bear shearing force again while bearing rotation friction, is unfavorable for its transmitting thrust, therefore need to design a kind of can the new open type drive chain of transmitting thrust.

Summary of the invention

For the defect existed in prior art, the object of this invention is to provide a kind of drive chain.This chain effectively can reduce the wearing and tearing of chain rivet and carrier bar, makes chain possess the effect transmitting Driving force simultaneously.

For reaching above object, the technical solution used in the present invention is: a kind of drive chain, comprise some outer plates facing each other and inner plate, the two ends of described outer plate and inner plate are equipped with axis hole, penetrate chain rivet in described axis hole adjacent described outer plate and inner plate are linked together, on described chain rivet, cover has axle sleeve, and the top of outer plate and inner plate is provided with plane of constraint.

Further, the plane of constraint of described outer plate extends to the inner side of described outer plate, the described plane of constraint of described inner plate extends to the outside of described inner plate.

Further, when chain is bending, connected described outer plate, the described plane of constraint of inner plate abut against together, common formation transmission plane.

Further, described chain rivet extends to outside described outer plate, inner plate both sides.

Further, the part cover that described chain rivet extends to outside described outer plate, inner plate both sides has guideway.

Further, outside described outer plate, inner plate both sides, be also provided with the guide channel that can hold described guideway and roll.

Effect of the present invention have following some:

1. decrease the shearing force suffered by chain rivet, decrease the wearing and tearing of chain rivet and carrier bar, extend the life-span of chain;

2. chain not only has the effect transmitting pulling force, also has the effect transmitting thrust simultaneously;

3. the transmission accuracy of chain is higher, and structure is firmer, and reliability is higher.

Embodiment

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

In order to reach the object reducing the chain rivet of chain and the wearing and tearing of carrier bar, and making chain possess the effect transmitting thrust, on the basis of existing common open type chain, being realized by increase plane of constraint and guide channel.

As shown in Figure 1, a kind of drive chain, comprise some outer plates facing each other 1 and inner plate 2, the two ends of described outer plate 1 and inner plate 2 are equipped with axis hole 6, one end of described outer plate 1, inner plate 2 is linked together by the chain rivet 4 be through in described axis hole 6, the part cover that described chain rivet 4 is clipped between described outer plate 1 facing each other, inner plate 2 has axle sleeve 3, and the top of outer plate 1 and inner plate 2 is provided with plane of constraint 7.

As shown in Figure 2, the plane of constraint 7 of described outer plate 1 extends to the inner side of described outer plate 1, the described plane of constraint 7 of described inner plate 2 extends to the outside of described inner plate 2 (structure of inner plate 2 is similar with outer plate, and just the bearing of trend of the plane of constraint at top is contrary).Outer plate 1 is the same with the width of the plane of constraint 7 on inner plate 2.When chain is not bending (under chain straightened condition), (abutting against together) closely can be connected between the plane of constraint 7 at described interconnective outer plate 1, inner plate 2 top, the transmission plane of a common formation long strip, relaxed state is between carrier bar main body under plane of constraint 7 and chain rivet 4, the transmission plane be made up of multiple plane of constraint 7 to bear the pressure between each carrier bar, thus significantly reduces the shearing force that chain rivet 4 bears.

Because the shearing force of originally being born by chain rivet 4 is converted into the pressure born between each plane of constraint 7, the wearing and tearing of chain rivet 4 under the condition of high thrust, Reusability are greatly reduced, simultaneously, the stressed arc surface by chain rivet 4 of chain is made to become plane between each plane of constraint 7, add the rigidity of whole chain under the state of bearing thrust, thus improve transmission accuracy and the reliability of chain.

In addition, chain rivet 4 stretches out, and outside the both sides protruding from outer plate 1, inner plate 2, and this part protruded outside is also overlapped and had rotating guideway 5.Outside the both sides of outer plate 1, inner plate 2, also be provided with guide channel, guide channel can hold the guideway 5 of chain both sides, when chain setting in motion, guideway 5 can roll in guide channel, both chain can have been made to run according to the direction of guide channel, chain can have been avoided again because deadweight sinking causes transmission to be obstructed, further increase transmission accuracy and the reliability of chain.

Device of the present invention is not limited to the embodiment described in embodiment, and those skilled in the art's technological scheme according to the present invention draws and other mode of execution belongs to technological innovation scope of the present invention equally.
