What’s a Disc Coupling?

Disc coupling connects two shafts with a flexible, spring-loaded connection to transfer power with minimal loss. The two main types are single and double disc, with the latter having more flexibility. Coupling allows for variations in shaft positions and individual bending, increasing strain capacity. Double disc has a secondary disc for greater flexibility and may be made of insulating material.

Disc coupling is a method of transferring power between two shafts. The couplers connect to the ends of the two shafts, creating a bridge between them. Couplers usually have a little leeway in their design; this explains the shaft mismatch and gives a small amount of flow during operation. There are two main types of disc coupling systems; single disc and double disc. These disc coupling systems work in a similar way, but the double disc system has more freedom than the single disc version.

One of the basic functions in any power generation system is the rotation of the trees. Whether the energy comes from an external source, such as a water wheel, or from within the system, such as a car engine, nearly all power systems rely on a shaft. This breakthrough provides core power that is transferred through the system to the operating areas.

One of the hardest parts of any power system is getting power to the areas needed. If the tree is too stiff, it will break or bind under strain; but, if it is too slow, it will lose power. To combat this problem, users have come up with a system called pairing. Coupling takes two shafts and connects them together using an external connection. When coupled, the two shafts rotate as one, but do not touch.

Generally, once mated, the two shafts are permanently joined. Most mating systems create a semi-permanent connection; it only comes off if a piece physically breaks. This connection allows power and torque to be transferred between shafts with minimal power loss.

Pairing also offers other benefits. When shafts are coupled, variations in shaft positions can be considered. This allows two shafts that don’t line up perfectly to still transfer power as if they did. Additionally, the coupling allows the shafts to bend individually. When subjected to severe stresses, the two shafts flex independently of each other, increasing the strain that can be applied to the system before a shaft fails.

A disc coupling system is a low profile, adaptable type of coupling. A single disc coupling system consists of two hubs that connect to the two shafts and a disc spring that connects them together. These couplers flex much more than other coupling systems, as they have a spring-loaded connection rather than a fixed connection.
The double disc version is almost the same as the single, except that it has a secondary disc between the two hubs. Each hub is connected to a spring and those two springs connect to the central disc. This central disc creates an even greater flex point, as there are two springs rather than just one. Additionally, the central disc may be made of an insulating material, preventing the transfer of heat and electricity through the connection.
