Disc coupling: Transfers torque from a driving to a driven bolt extraneously on a typical bolt circle. Torque is transmitted between the bolts through a progression of thin, stainless steel riveted discs pack. Misalignment is cultivated by deforming of the material between the bolts.
A disc coupling is a superior performance motion control (Servo) coupling intended to be the torque transmitting component while accommodating for shaft misalignment.
There are two unique styles of disc coupling:
Single Disk Style couplings are made out of two hubs and a single, flat, stainless steel plate spring riveted disc pack.
Double Disk Style coupling is likewise made out of two hubs yet has an extra centre spacer sandwiching two riveted disc springs.
The middle spacer can be made out of a similar material as the hubs, yet is some of the time accessible in protecting joints, which makes the coupling electrically isolating.

The contrast between the two styles is that single disc couplings can’t suit parallel misalignment because of the complex bending that would be expected of the lone plate.
Double disc styles enable the two discs to twist in inverse ways to all the more likely oversee parallel offset. The discs are fastened to the hubs with tight-fitting pins that don’t permit any play or reaction between the disc and the hubs.
The discs can be bent effectively and accordingly, disc couplings have the absolute least bearing burdens accessible in a motion control coupling.
Torsionally hardened and still adaptable, disc couplings are an extraordinary answer for rapid applications.
The drawback is that they are more fragile than the normal coupling and can be harmed whenever abused. Exceptional consideration ought to be taken to guarantee that misalignment is inside the evaluations of the coupling.

A disc coupling is a kind of flexible coupling appropriate for high-performance control applications. The coupling transmits torque from a driving to a driven bolt extraneously on a typical bolt circle.
This torque is transmitted between the bolts through a progression of thin, stainless steel plates amassed in a pack.
This flexibility, however; has a drawback. While the coupling is appropriate for high-speed applications, it is likewise more delicate than most different couplings.
The disk springs can be effectively bent out of shape, which means the coupling can just deal with low bearing loads.
