Chain coupling
The chain coupling uses a common chain and is meshed with two parallel sprockets with the same number of teeth at the same time. The main difference between chain couplings of different structural types is that different chains are used. Common chain couplings are double row roller chain couplings, single row roller chain couplings, toothed chain couplings, nylon chain couplings, etc. The chain coupling has the advantages of simple structure (composed of four parts), convenient assembly and disassembly, no need to move the two connected shafts during disassembly, compact size, light weight, certain compensation ability, low requirements for installation accuracy, reliable operation, long service life, low cost, etc. It can be used for shafting transmission of textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery. It is suitable for high temperature, humid and dusty working conditions, not suitable for high-speed, severe impact load and axial force transmission occasions. The chain coupling should work under the condition of good lubrication and protective cover.
