Disc coupling: by definition, transmits torque from a driving to a driven bolt tangentially on a commonbolt circle. Torque is transmitted between the bolts through a series of thin, stainless steel discs assembled in a pack. Misalignment is accomplished by deforming of the material between the bolts.

Adisc couplingis a high performance motion control (Servo)couplingdesigned to be thetorquetransmitting element (by connecting twoshaftstogether) while accommodating forshaft misalignment. It is designed to be flexible, while remainingtorsionallystrong under high torque loads. Typically, disc couplings can handle speeds up to 10,000RPM.

There are two different s of disc coupling:

Single DiscStyle couplings are composed of two hubs (the ends of the coupling, which are typically made from aluminum, but stainless steel is used as well) and a single, flat, stainless steel disc spring

Double DiscStyle coupling is also composed of two hubs, but has an additional center spacer sandwiching two disc springs. The center spacer can be made out of the same material as the hubs, but is sometimes available in insulating acetal, which makes the coupling electrically isolating.

The difference between the two s is that single disc couplings cannot accommodate parallel misalignment due to the complex bending that would be required of the lone disc. Double disc s allow the two discs to bend in opposite directions to better manage parallel offset. The discs are fastened to the hubs (and center spacer on double disc s) with tight fitting pins that do not allow any play or backlash between the disc and the hubs. The discs can be bent easily and as a result, disc couplings have some of the lowest bearing loads available in a motion control coupling.

Torsionally stiff and still flexible, disc couplings are a great solution for high speed applications. The downside is that they are more delicate than the average coupling and can be damaged if misused. Special care should be taken to ensure that misalignment is within the ratings of the coupling.

Advantages of disc coupling

1. Eliminates the need for lubrication and coupling maintenance

2. Coupling can be inspected without disassembly

3. Condition of disc packs can be inspected with a strobe light while the machine is running

4. Note: It is not recommended that couplings be operated without coupling guards.

5. Easy to assess equipment misalignment

6. Torsionally rigid without any backlash

7. No wearing parts

8. Resistance to harsh environments

9. Long life when properly sized and aligned

10. High power density (higher torque for a given outside diameter)

TAP series

Have all the advantages of TAL

Suitable for the shafts wide differing from each other in diameter and middle/low speed applications

Especially for the equipments such as electric generators and electromotors with big diameter shaft

Beneficial to protect small shaft equipment
