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
