Structure improved chain

Abstract

The invention discloses a structure improved chain. The structure improved chain comprises a plurality of groups of main chain plates and a plurality of groups of auxiliary chain plates, wherein boththe number of each group of main chain plates and the number of each group of auxiliary chain plates are two, the two main chain plates in each group are arranged in a directly facing manner, and thetwo auxiliary chain plates in each group are arranged in a directly facing manner; the main chain plates and the auxiliary chain plates are distributed in a staggering manner; the two sides of the outer wall of each auxiliary chain plate are symmetrically and fixedly connected to connecting plates; movable grooves corresponding to the connecting plates are formed in the outer wall of each main chain plate; two symmetrical sleeves are fixedly connected between the two main chain plates facing to each other directly; the outer walls of the sleeves are in sleeve connection with rollers; the two sides of the outer wall of the middle of each sleeve are symmetrically and fixedly connected to convex blocks; a plurality of balls are uniformly arranged on the outer wall of each roller in a surrounding manner; a pin shaft penetrates the main chain plates, the connecting plates and the sleeves; the outer wall of one end of the pin shaft is in sleeve connection with an annular fixture block; and one end, far away from the annular fixture block, of the pin shaft, is in threaded connection with a nut. The structure improved chain has the beneficial effects that the structure improved chain is simple in structure and easy to operate; the frictional force is reduced; the biting of a chain wheel and the chain is facilitated; and the service life of the structure improved chain is prolonged.

Description

technical field [0001] The invention relates to the technical field of chains, in particular to a structure-improved chain. Background technique [0002] Chains are generally metal links or rings, mostly used for mechanical transmission, traction, chains used to obstruct traffic passages, and chains for mechanical transmission. Among similar products, the chain product series are divided according to the basic structure of the chain, that is, according to the shape of the components, the parts and parts meshing with the chain, and the size ratio between the parts. There are many types of chains, but their basic structures are only the following types, and the others are all deformations of these types. We can see from the above chain structures that most chains are composed of chain plates, chain pins, bushings and other components. Other types of chains just make different changes to the chain plates according to different needs, some are equipped with scrapers on the cha...

Problems solved by technology

Other types of chains just make different changes to the chain plates according to different needs, some are equipped with scrapers on the chain plates, some are equipped with guide bearings on the chain plates, and some are equipped with rollers on the chain plates, etc. These are all modifications for different applications, but the existing chain will make a huge noise when meshing with the sprocket, and the chain is severely worn, and the whole machine vibrates violently when it is running, which reduces the service life.
