Mechanical Features and Designs

A coupling is a device that connects two shafts for the purpose of transmitting power. The initial shaft is called the driver, as that is where the power is coming from. The second shaft connected to the coupling is referred to as the driven shaft. The driven shaft connects an attachment, such as a bucket or grapple, that allows the machine to carry out an assortment of tasks. Couplings are typically used on, but not limited to, equipment such as cranes, loaders, and excavators. Essentially any machine that can benefit from an attachment or implement can use a coupling to do so.

Couplings have become a standard component of some types of equipments. Most excavators will include couplings to add attachments, making them flexible for different applications such as digging, lifting, pushing, and cutting. Types of attachments that can be connected to couplings include a grapple for grasping materials, an auger, a hammer, and thumb attachments.

Some manufacturers specialize in the production of couplings.

Hydraulic snap couplings enable the shafts to be connected more quickly. Once the shafts are connected via coupling, they are not easily disconnected.

There are many types of couplings: rigid, muff, beam, pin, flexible rubber disc, spider, bibby, chain, gear, metastream, fluid, and universal.[1]
