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
