The Importance of Gearbox Flexible Coupling
                     The Importance 
Of Gearbox 
Flexible Coupling
Gearbox flexible coupling is used to transmit torque from one
shaft to the other when the shafts are slightly out of alignment.
Both inboard engine mounts and flexible couplings for geared
The drives have long been key in improving a marine vessel's
Importance performance and longevity. They are designed to isolate engineand drive line vibrations and improve the overall performance of a
Of Gearbox navigational system. Generally, they are used for vibration
damping and noise reduction in rotating shaft applications.
Flexible What is a Flexible Coupling?
Coupling These couplings use fixed position flexible metallic, rubber, or
plastic elements that rotate with the shafts to absorb
misalignment. The flexibility of these elements can be controlled
by adjusting their diameter.

Most of these elements are molded, though some are machined.
This allows the elements to be more accurate in their dimensions,
which can increase the axial and radial tolerances.
Why is a Flexible Coupling Important? 
The The type of coupling is crucial in determining the maximum
Importance tolerance of misalignment and axial position change that it canaccommodate. For instance, a gear-type coupling will have a larger
Of Gearbox tolerance than a flexible element type.
Misalignment tolerance is stated on the coupling drawing. The
Flexible larger the tolerance, the longer it will last.
Coupling What are Misalignments?
Angular offset is a type of misalignment that occurs when the axes
of the shafts do not meet in a straight line at the center points of
the coupling. Foundation setting, pipe strain, loose anchor bolts, or
thermal movement can cause it.

This can cause the coupling to fracture near the bolt hole or fret in
the area around the crack. It can also cause a loss of torque.
Often, these misalignments are not noticed until they affect the
The operation of the equipment. In such cases, the operator should
check with their supplier to determine what they are allowed.
Importance They should always be careful to operate their equipment within
its misalignment capacity. Otherwise, the life of the equipment will
Of Gearbox be significantly reduced.
