Lengthened shaft roller double-row conveying chain and technology thereof

Abstract

A lengthened roller double-row conveying chain comprises chain plates, pin shafts, rollers and sleeves. The chain plates include the outer chain plate and the inner chain plate. Two conveying chain bodies spaced by a certain distance are arranged and connected through shaft rollers. The two ends of the shaft rollers and the pin shafts are the same in shape and replace the positions of the pin shafts. The middle parts of the shaft rollers are thicker than the two ends of the shaft rollers. All parts of the conveying chain bodies are processed through multiple special machining technologies, for example, the strengthening carbon supplementing thermal treatment technology and the metal seepage technology are sequentially carried out on the surfaces of the pin shafts and the shaft rollers. The strength of the conveying chain bodies is high, the bearing area of the conveying chain bodies is large, the bearing capability and transmission precision are high, and the rotating speed is even. The synchronous running conveying step pitch is matched, the anti-impact performance and wear-resistant performance are high, and ultra-high corrosion-resisting performance is achieved.

Description

technical field [0001] The invention relates to the technical field of conveying chains, in particular to an extended shaft-roller double-row conveying chain and its technology. Background technique [0002] The conveyor chain is composed of a series of bearings, which are fixed by chain plates with restraint, and the positional relationship between them is very precise. Each bearing consists of a pin and a bushing on which the chain's rollers rotate. Conveyor chains are suitable for the transportation of various boxes, bags, pallets and other items. Bulk materials, small items or irregular items need to be transported on pallets or in turnover boxes. It can transport a single piece of material with a large weight, or withstand a large impact load. The double-row conveyor chain consists of two rows of chains installed in parallel. [0003] At present, ordinary double-row conveyor chains are combined together, there is no shaft roller between the chains, the load-bearing s...

AI Technical Summary

Problems solved by technology

[0003] At present, ordinary double-row conveyor chains are combined together, there is no shaft roller between the chains, the load-bearing strength is poor, the load-bearing area is small, the pitch of the blanking chain plate is large, the synchronous operation does not match the conveying step, and the heat treatment of ordinary materials , the chain strength is low, the service life is short, the surface of the chain parts is conventionally oiled to prevent rust, and the corrosion resistance is poor
