Yes these are flexible however they are not a one-size-fits-all proposition. Rather the flexible couplings are far from it, in fact.  It is needless to mention that few drive train components are as deceptively simple as a coupling. Two rotating shafts, a coupling to connect the two, and all systems are go – or seemingly so.

That’s the basic thing indeed however operations can sputter sometimes to a halt. In fact unless the couplings can readily contend with the performance requirements of the application and this is exactly where the speed and torque transmission, misalignment among connecting shafts etc should be considered, among other conditions. And all these and much more make Vulkan coupling ez spares a staggering hit. 

It is thus pertinent to be mentioned here that while their rigid counterparts are specified when precise alignment is required, however it is only the flexible couplings, which are employed when axes are at a slight angle or slightly displaced. Displacement might occur due to the result of tolerance build up or the rigors of operations, including bearing wear or structural deflection. 

So, here’s a brief description of the various types of misalignments – For instance the angular misalignment occurs when shaft centerlines intersect to form an obtuse angle. On the other hand the Lateral misalignment, results from lateral displacement among parallel centerlines. The Skewed misalignment refers to combinations of angular and lateral misalignment and the axial misalignment on the other hand relates to the movement of shaft members toward or away from one another. 

Of course the flexible-shaft and Vulkan coupling ez spares accommodate misalignment while transmitting torque between shafts. Depending on the configurations, the couplings also impart exceptional torsional rigidity, torsional strength and vibrational damping.

While the import of these attributes varies among operations, growing demand for high-speed, high-efficiency processing is driving greater demand for high-torque, high-misalignment, and low-inertia couplings with minimal compromise to torsional stiffness.

Keep in mind, for the systems requiring continuous motion and accuracy, rely on superior torsional strength such as that exhibits through the flexible gear couplings.

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
