Sealed refueling-free chain

Abstract

The invention provides a sealed refueling-free chain, and relates to the technical field of chains. The sealed refueling-free chain comprises outer chain plates, inner chain plates, a pin shaft, a roller and a roller, the two inner chain plates are located between the two outer chain plates, and the pin shaft penetrates through the two outer chain plates and the two inner chain plates. Through the arrangement of the oil filling port, the oil storage tank, the first pipeline and the second pipeline, lubricating oil can be added into the oil storage tank through the oil filling port, so that the situation that the pin shaft is lubricated by the lubricating oil after the chain is used for a long time can be avoided, and the service life of the chain is conveniently prolonged; the lubricating oil is promoted to absorb heat on the roller, so that the temperature of the roller during working can be reduced, the lubricating oil can also clean impurities in the roller, normal working of the roller is guaranteed, the pin shaft can be lubricated through the second pipeline, and excessive abrasion of the roller and the pin shaft can be avoided.

Description

technical field [0001] The invention relates to the technical field of chains, in particular to a sealed oil-free chain. Background technique [0002] Chains are generally metal links or rings, which are mostly used for mechanical transmission and traction. It is a chain used to obstruct the passage of traffic (such as in the street, at the entrance of a river or a harbor), and a chain for mechanical transmission; [0003] Chinese patent (notification number: CN213419791U, announcement date: 2021.06.11) discloses a sealed oil-free chain, including a chain body and an oil-free mechanism, and a solid lubricant is filled in the inner cavity of the sleeve. Heat will be generated during the process, so that the solid lubricant will melt and seep out through the penetration hole, and lubricate the pin shaft and the sleeve, the sleeve and the roller, which is simple and convenient, so that the whole can be used normally without oiling, and the roller The outer surface is equipped...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sealed oil-free chain, which solves the problem that the existing equipment that can add lubricating oil is not installed, so that the chain does not have enough lubricating oil to lubricate the pin shaft after long-term use. As a result, the service life of the chain has not reached the ideal period
