8 Different Types of Couplings

by Kristen White Blogger

The elements here are normally the shafts. Therefore, a shaft coupling is a mechanical device that connects rotating shafts and absorb any misalignment between them. Shaft couplings can both be rigid and flexible, depending on the needs and requirements of the system. Power or torque can be transmitted between two rotating shafts in motors and pumps.

Types of Couplings

1. Beam Couplings

Beam couplings are those that have single or multiple helical cuts in their structure. These couplings can cater to parallel misalignments upto 0.025 inches and angular misalignment till 7 degrees. These couplings find applications in motion control devices.

2. Bellow Couplings

These couplings are also meant to be used for motion control in devices. Multiple convolutions of metal are present in these couplings to suit their applications. Multiple convolutions also provide good torsional stiffness. These couplings have lower levels of parallel and angular alignments because of high torsional stiffness. The torque transmission abilities of these couplings are similar to that of beam couplings. Make the most of the best Straub coupling services.

3. Chain Couplings

These couplings are used for power transmission. Power up to hundreds of horsepower can be transmitted using these couplings. The angular and parallel misalignments of these couplings have a lower range as compared to the others discussed above. These couplings use special roller chains and chain sprockets. These components allow them to function flexibly.

4. Jaw Couplings

Jaw couplings can be used for both motion control and power transmission. The design of these couplings is such that they can offer you torque transmission without backlash. The accommodation range for parallel and angular misalignment is low - 0.01 inch and 1 degree. Jaw couplings can operate without any lubrication also.

5. Diaphragm Couplings

If you need couplings that can help you in high power transmission, these are the ones for you. These couplings are generally found in turbomachinery. They have metal convoluted discs that transmit power to the inner shaft which is then transmitted out through the diaphragm and runs the machinery. These couplings can also operate without any lubricants. High torque and high speed are some of the other features of these couplings.

6. Disc Couplings

Single or multiple discs are used in the manufacture of disc couplings. These couplings are also used for power transmission. The flexibility provided by the thin metal discs are used to accommodate for the parallel and angular misalignments. Disc couplings are particularly not good at accommodating parallel misalignments.

7. Gear Couplings

These couplings are commonly used in pairs. They have high torque transmitting capabilities. One disadvantage of using gear couplings is that they require lubricants for functioning properly.

8. Grid Couplings

Coupling hubs are connected to each other in these couplings via spring-like connecting elements. They are used for high torque transmission and also have shock-absorbing capabilities. Hire the best Todo coupling services.

You need to consider several factors before choosing a coupling for your machines and devices.
