Chain coupling is the use of common chain, while the same number of teeth in the same side of the sprocket bite, chain coupling structure is mainly different from the chain used. We usually have a common double row of roller chain coupling, single row of roller chain coupling, tooth chain coupling, nylon coupling and so on. Chain coupling is characterized by simple structure, generally composed of four separate pieces, easy disassembly, disassembly without moving the shaft at both ends of the shaft, compact size, light weight, a certain degree of compensation, the installation accuracy requirements High, reliable, long life, low cost and other advantages of some of the columns. Botou City Friends of Sheng Co., Ltd. of the technical staff concluded chain coupling can be used for textile, agricultural machinery, lifting transport, engineering, mining, light industry, chemical machinery shaft drive. Suitable for high temperature, humidity and dusty environment, not suitable for high-speed, severe impact load and transmission of axial force occasions, the chain coupling should be a good lubrication and a protective cover under the conditions of simple structure, Demolition convenient. Reversal when the free travel, should not be used for a large impact load reverse drive.

    Then the chain coupling failure is caused by what causes? Here we come to sum up: First, overload overload overload operation will cause damage to the coupling itself, followed by the chain or chain wheel length Time of excessive wear and tear, and then there is no chain coupling shell is installed, resulting in chain corrosion, fracture.
