China Supplier Disc Coupling for Heavy-Duty Machinery

Product Description

Disc coupling: by definition, transmits torque from a driving to a driven bolt tangentially on a common bolt 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.

A disc coupling is a high performance motion control (Servo) coupling designed to be the torque transmitting element (by connecting two shafts together) while accommodating for shaft misalignment. It is designed to be flexible, while remaining torsionally strong under high torque loads. Typically, disc couplings can handle speeds up to 10,000 RPM.

There are two different styles of disc coupling:

Single Disc Style 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 Disc Style 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 styles is that single disc couplings cannot accommodate parallel misalignment due to the complex bending that would be required of the lone disc. Double disc styles 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 styles) 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)

TAG series

• Main choice for middle/high speed applications
• Factory-assembled middle transmitting unit, dynamic balance precision well kept, easy to mount/dismount
• Big hub design for relatively large allowable shaft diameters
• Have all the advantages of TAL
• Suitable for longer spacer distance applications compared with TAL
