The traditional chain generally increases the wear resistance of the chain by increasing the strength, hardness and the like of the material or the surface of the material, and can effectively reduce the wear by improving the lubrication state of a wear interface, and usually, a liquid or paste lubricant is added and injected on the wear interface. However, with the rapid development of industry and science and technology, the use environment of the chain is more and more, and lubricating oil or lubricating grease used under certain working conditions cannot meet the requirements of customers.
SUMMERY OF THE UTILITY MODEL
In order to solve the deficiency that prior art exists, this novel high wear-resisting self-lubricating chain that provides, non-maintaining in its use, the wearability is higher than current non-maintaining chain, is applicable to the operational environment such as packing, printing and weaving and requires higher, be not convenient for scribble lubricating oil or the occasion that does not allow to scribble lubricating oil.
In order to achieve the purpose, the technical scheme of the novel solution is as follows:
a high-abrasion-resistance self-lubricating chain comprises an inner chain plate, an outer chain plate, a sleeve, a roller and a pin shaft, wherein an abrasion-resistance self-lubricating coating is arranged on the surface of the pin shaft.
Preferably, the sleeve is an oil-containing sleeve subjected to process treatment.
Preferably, the wear-resistant self-lubricating coating is a composite coating.
Preferably, the composite plating layer is a Ni-P-graphite chemical composite plating layer.
Preferably, the Ni-P-graphite chemical composite coating needs to be subjected to 400 ℃ after being formedAnd heat treatment for at least 1 hour; after heat treatment, the Ni-P-graphite chemical composite coating is changed from amorphous state to crystalline state, and the crystalline state stable phase nickel-phosphorus intermetallic compound Ni generated in the heat treatment process3P is a hard phase, thereby increasing the hardness of the plating.
Preferably, the processing technology of the Ni-P-graphite chemical composite coating is as follows: cutting off the raw material of the pin shaft; performing fillet treatment on the end part of the pin shaft after cutting; carrying out heat treatment on the round-corner treated pin shaft; carrying out circular grinding on the outer wall of the pin shaft after heat treatment; polishing the outer surface of the round pin shaft; plating a Ni-P-graphite chemical composite plating layer on the outer surface of the pin shaft; carrying out heat treatment on the Ni-P-graphite chemical composite coating at 400 ℃ for at least 1 hour; and polishing the outer surface of the Ni-P-graphite chemical composite coating.

This neotype theory of use:
this neotype round pin axle surface is equipped with Ni-P-graphite chemical complex plating layer, graphite particle is added on traditional chemical nickel plating's basis to the complex plating layer, and concrete plating process does not do and does not give unnecessary details.
The composite plating layer formed after adding the graphite particles can ensure the corrosion resistance and acid and alkali resistance of the traditional chemical nickel plating and the surface high hardness characteristic (the HV of the surface of the Ni-P-graphite chemical composite plating layer can reach 1000), and meanwhile, an antifriction film can be formed on the surface of the pin shaft by the graphite particles in the using process of the chain, so that the friction coefficient of the surface of the plating layer is greatly reduced, the self-lubricating function is realized, and the abrasion loss of the chain can be greatly reduced through the high wear resistance and the self-lubricating function.
Because two most important parts that influence chain wearability are sleeve and round pin axle, so this is novel when carrying out technological improvement to the round pin axle, still set up the sleeve into oiliness sleeve (relevant technology has been disclosed, does not do the repeated description), through oiliness sleeve and the round pin axle that is equipped with Ni-P-graphite chemical complex plating layer, can make the life of chain prolong by a wide margin, can do the life non-maintaining.
