What Is a Chain Coupling?

The chain coupling uses a common chain and meshes with two parallel sprocket wheels with the same number of teeth at the same time. The main difference between different types of chain couplings is the use of different chains. Common two-row roller chain couplings Row roller chain coupling, toothed chain coupling, nylon chain coupling, etc. The chain coupling has a simple structure (composed of four pieces), is easy to assemble and disassemble, and does not need to move the two connected shafts during disassembly. It is compact in size, light in weight, has a certain compensation ability, does not require high installation accuracy, is reliable, and has a long service life. Longer and lower cost. Can be used for textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery shaft drive. Suitable for high temperature, humid and dusty working environment, 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.

The chain coupling uses a common chain and meshes with two parallel sprocket wheels with the same number of teeth at the same time. The main difference between different types of chain couplings is the use of different chains. Common two-row roller chain couplings, single Row roller chain coupling, toothed chain coupling, nylon chain coupling, etc. The chain coupling has a simple structure (composed of four pieces), is easy to assemble and disassemble, and does not need to move the two connected shafts during disassembly. It is compact in size, light in weight, has a certain compensation ability, does not require high installation accuracy, is reliable, and has a long life Longer and lower cost. Can be used for textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery shaft drive. Suitable for high temperature, humid and dusty working environment, 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.

Simple structure and easy assembly and disassembly. There is a free stroke when reversing, and it is not suitable for reverse transmission with a large impact load.

Several reasons for the failure of the coupling:

First, overload, the coupling is used more than the load;

Second, the chain or sprocket is worn out for a long time;

3. The cover is not installed, and the chain is rusted and broken.

Features: The chain coupling has a simple structure (composed of four pieces), is easy to assemble and disassemble, and does not need to move the two connected shafts during disassembly. It is compact in size, light in weight, has a certain compensation ability, does not require high installation accuracy, and works reliably , Long life, low cost and so on.

Roller chain couplings can be used for shafting transmission of textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical and other machinery, suitable for high temperature, humid and dusty working conditions, not suitable for high speed, severe impact Where loads and axial forces are transmitted, the chain coupling should work under conditions of good lubrication and a protective cover.
