Whether or not to involve the flexible couplings!

Flexible Couplings are typically the devices, which are used to connect two shafts together. To put things simply; these are used either for connecting a gearbox to a motor, or gearbox to a customer’s application. As a matter of fact the flexible Vulkan coupling ez spares are thus easy to connect and disconnect and can be used for transmitting the full power from one shaft to another. Worry not; flexible couplings are able to compensate for all types of shaft misalignment.

These are basically suitable for plug-in assembly devices and are also pretty easy to mount. It is necessary to mention that the sheer flexible elements thus help in compensating the shaft misalignments and also helps in absorbing the moderate shock loads of motor or driven machine.

There is no denying therefore; standard Vulkan coupling ez spare of a wide modular design range and application thus also covers a multitude of applications.

Benefits of Using the Range of Flexible Couplings

·        It guarantees a rather reliable transmission of the torque even in case of  shaft misalignment with low restoring forces

·        Suitable for vertical mounting position

·        Low degree of maintenance

·        Availability of many series and sizes

In short, the flexible couplings offer the ultimate 4-Way Flexing Action. They also absorb all types of shock, vibration and misalignment.

Are you still in dilemma whether or not to involve the flexible couplings? Well, here are a few significant pointers to mull over

Provides easy & quick installation – they can be installed quickly and easily because there are no seals. You can in fact check the alignment by placing the straightedge across the outside of the precision-machined flanges. No special tools are needed for installation.

No Lubrication Required And Offers Trouble-Free Operation –  Worry not; the teeth of the sleeve lock into the teeth of the flanges pretty easily.  The absence of any clamps or screws makes Vulkan coupling ez spares the most popular choice for trouble free operation. Also, there is no rubbing action of metal against rubber to cause wear.

This means flexible couplings are not affected by abrasives, dirt, or moisture. Yes, this eliminates the need for lubrication or maintenance and also provides clean, dependable, quiet performance

When life calls for Vulkan coupling ez spares & Flexible Coupling

Companies that upgrade their pumping systems, or companies that  install new systems, with the objective of improving efficiency commit themselves to substantial investment - not only in terms of the pumps themselves but also with new energy-efficient motors to drive them. However; there is no denying that achieving the optimum pump/motor interface would not be a problem if driving and driven shafts were perfectly aligned. Interface would not be a problem if machines did not vibrate, and if shafts never actually moved.

This is why flexible couplings are required. Typically the coupling is essentially a type of coupling that can connect aligned shafts or flex to accommodate shafts that are slightly misaligned.

Over-sizing a flexible coupling can result in a reduction in required flexibility or misalignment compensation. On the other hand, the flexible Vulkan coupling ez spares that are too large can put additional stresses on the pumps and motors being coupled.

With these pitfalls in mind, the pump user is equipped to undertake a selection procedure that essentially depends upon four basic conditions of shaft misalignment, or movement. These conditions include

parallel misalignment, angular misalignment, end float and the torsional flexibility. As a matter of fact; to be considered flexible, a coupling must handle parallel and angular misalignment.

Couplings with four-way flexibility need to accommodate both end-float and torsional movement.

It goes without saying that Shaft misalignment and rotor unbalance are major concerns in rotating machinery. It is also to be mentioned that the system response depends heavily on the relation between the system natural frequencies and the motor rotational speed. The matter of fact is the vibrations induced by misalignment are amplified into major vibration sources.

There is hardly any denying, the purpose of a flexible coupling is essentially to absorb the shaft restoring loads while maintaining some amount of rigidity in rotation and transmission of torque.

You should also bear in mind that the wide range of torsionally flexible couplings, can in fact compensate for relatively large shaft misalignments, while zero backlash couplings, which offer a greater degree of precision in their rotation, often come at a compromise to flexibility. 

Industry specifications on flexible Vulkan coupling ez spares are however limited to features such as bores/keyways and fits, balance, lubrication, and parameters for ratings.

Discussing in detail about the Flexible Coupling & Vulkan coupling ez spares

The idea is simple – mechanical couplings are typically used in the connection of rotating shafts for the greater purpose of transferring the rotary motion and torque. As it is with any other mechanical devices, a coupling must match its’ intended purpose and application parameters and the same stands true for the flexible couplings as well. There are thus a number of factors such as performance, environmental, use and service factors that comes into play for the coupling to work properly. 

When the flexible Vulkan coupling ez spares is selected with these design parameters in mind, and when installed and operating correctly, the coupling should have no failure issues over its’ lifetime. However, when the criteria are not met the coupling can prematurely fail and this may result in inconvenience, dire financial loss or personal injury. 

The good news is the choice of Flexible Coupling available to today’s engineers can be daunting; however, you can follow our guidelines to arrive the optimum coupling. Consider the following aspect – 

Does the flexible coupling provide adequate misalignment protection?

·        Can it transmit the required torque?

·        Do you need the axial motion or axial stiffness?

·        Can it sustain the required speed of rotation?

·        Will it fit within the available space envelope?

·        Does it provide the electrical isolation between the shafts?

·        Will it have the required life expectancy?

The Standard Range of Flexible Coupling however comprises

·        Shaft to shaft

·        Shaft to shaft with increasing shaft engagement

·        Flywheel to shaft

·        Flywheel to shaft with increased shaft engagement

 The significance of proper flexible coupling installation - 

Of course you can prepare the most delicious meal possible but fail to serve it properly will send your guests home disgruntled. The same holds true for the Vulkan coupling ez spares. The apt design and the attention when selecting a shaft coupling is essentially meaningless if the coupling is not installed properly or if the actual application parameters are outside of original design criteria. 

So here is the guideline of proper installation of the flexible couplings –

·        Prepare the coupling and shafts prior to installation by cleaning the mating parts. Also oil the shafts lightly.

·        Follow all instructions for fasteners

·        Don’t install the coupling too far left or right of the center line

·        Don’t install shafts too deep or too shallow in the hubs

·        Don’t introduce stress on the coupling by compressing or stretching it upon installation

·        Flexible Couplings must always be installed in their free-state

Application of the flexible couplings 

·        Generator sets

·        Pump set

·        Compressors

·        Wind turbines

·        Metal manufacture

·        Bulk handling

·        Pulp and paper industry

·        General purpose heavy duty industrial applications

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.
