Features of roller chains for couplings:Chain couplingIt uses a common chain to mesh with two parallel sprockets with the same number of teeth at the same time. The main difference between different structure types of chain couplings is the use of different chains. Common ones include double-row roller chain couplings and single-row rollers. Chain couplings, toothed chain couplings, nylon chain couplings, etc.The performance of double-row roller chain couplings is better than that of other structural couplings. It is widely used at home and abroad (KC series sprocket couplings). my country has also formulated it as a standard (GB6069-86).
When designing the overall structure of the coupling, pay full attention to the lubrication and dust prevention between the tooth surface and the roller, and add a shell.In addition to preventing dust and oil, it also has a protective effect.Because if the chain breaks, it may cause a personal accident.
It can be used in the shaft transmission of textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery. It is suitable for high temperature, humidity and dusty working conditions. It is not suitable for high speed, severe impact load and transmission of axial force. The chain coupling should work under the condition of good lubrication and protective cover.
