A brief discussion about Vulkan coupling ez spares, Flexible Coupling

Finally when the time comes for specifying replacements for mechanical power transmission couplings, it's common to take the easy path and find out something similar to the coupling that failed.

Or may be to apply a few over sizing fudge factors just to be conservative! Needless to say, it invites a repeat failure or often rather costly system damage. And the best solution is to add the flexible coupling without much delay.

Of course taking time to determine the right type of coupling is important  even if it only verifies the previous design. However it should lead you to something totally different that will work better and last longer. There is hardly any denying that it will reward you by extending the life of bearings, preventing fretted spline shafts, bushings and seals, minimizing noise and vibration, and cutting long-term maintenance costs.

In most of the cases industrial power transmission calls for flexible couplings rather than rigid couplings! It helps in forgiving minor shaft misalignment.

However determining the right type of flexible coupling and Vulkan coupling ez spares starts with profiling the application as follows :

·         type of prime mover

·         driven-system inertia values in relation to prime-mover inertia

·         vibration, both linear and torsional

·         shaft-to-shaft misalignment

·         axial (in/out) shaft movement

·         ambient conditions

The next step is however to review available types of flexible couplings to make sure which type best suits your application profile.

Typically, flexible couplings divide into two primary groups... metallic and elastomeric. While metallic types are all-metal designs the elastomeric types gain flexibility from using resilient, non-moving, rubber or plastic elements to transmit torque between usually metallic driving/driven hubs.

Metallic types are best suited to applications that require

torsional stiffness

operation in relatively high ambient temperatures

electric motor drive

relatively constant, low-inertia loads

Elastomeric types are best suited to applications that require

torsional softness

greater radial softness

lighter weight/lower cost, in terms of torque
