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.
