The coupling cover has a simple structure (composed of four pieces), convenient assembly and disassembly, no need to move the connected two shafts when disassembling, compact size, light weight, certain compensation ability, low requirements for installation accuracy, reliable work, Advantages such as longer life and lower cost.The characteristics of the coupling cover: The chain coupling uses a common cover and meshes with two parallel sprockets with the same number of teeth. The main difference between different structure types of chain couplings is the use of different covers, which are domestic Widely used in foreign countries (KC series sprocket coupling), my country has also formulated as a national standard (GB6069-86).The material of the coupling cover is generally made of aluminum, with sealing rings and bolts inside, the model number is 3012-12220.The chain is a double-row chain, ranging from 4 to 3 inches, and the sprocket is a double-row wheel, ranging from 4 to 3 inches.
