A brief discussion on Chain Couplings: A useful guide!

Chain coupling is defined simply as a three-piece flexible shaft coupling. The main use of this type of coupling is connecting the driving and the driven shafts in the process of mechanical power transmission. It is also quite helpful in solving the problem of misalignments that is quite a common thing to appear in connected shafts.

If we delve deeper into the structure of this coupling then one will see that it has identical right and left-hand sprocket. These sprockets are connected through duplex roller chains as well as acetal plastic chains.

Uses of Chain Couplings

Now, it is also important to understand and see where chain couplings are used? It is mostly used in low to moderate speed, high torque applications. Other features of this type of coupling include being rugged. Also, a major advantage that is offered by this coupling is that it is easy to install. If we have to talk about applications specifically then we have to mention line-shaft couplings on live-roller conveyers.

One can buy chain couplings with many variations in shaft sizes and capacities of torque. Now let us talk about misalignment. There are two basic kinds of misalignment that chain couplings can deal with. Firstly, it can deal with angular misalignment with a maximum of 1°. Secondly, for parallel, it mostly has a limitation of 2% of the chain pitch. In this regard, an important thing to note is that these allowances of misalignment are decreased in high-speed installation. Another major types of couplings are HRC Couplings.

There are a few things that one needs to know. The very first thing to know is the required bore and also the method of calculating the transmitted torque. Also one needs to know of multiplier supplied which will help rate the severity of the service. In this regard, we can also note that manufacturers have online calculators and this helps specifiers in better selection of couplings. One can also check Chain Coupling Catalogue for more.
