Flexible shaft couplings provide mechanical power in
the form of torque to pieces of rotary equipment. Manufacturers utilize
shaft couplings during the production of rotary equipment, such as power
transmissions, generators, pumps and turbines, in a variety of industries
including automotive, oil/gas, aerospace, water/waste treatment and construction
industries. Engineers mount rotary equipment upon shafts. Shafts aid
in the correct positioning of the equipment and supply the equipment
with an axis of rotation. Shaft couplings connect the shafts of rotating
equipment, allowing greater efficiency during operation. Manufacturers
determine the type of shaft coupling based on the presence of shaft misalignment.
In certain industrial applications, shafts remain aligned with one another,
in which case rigid shaft couplings remain an effective choice. However,
during operation, shafts tend to shift, causing misalignment. When shaft
misalignment is common, manufacturers choose flexible shaft couplings.
Flexible shaft couplings provide efficient accommodation for moderate
shaft misalignment. Shaft misalignment occurs when the shafts’ axes
of rotation become skewed. When shafts remain aligned with one another,
performance is optimum and the shafts’ axes of rotation intersect
in one straight line. Movement, bumps or vibration cause shaft movement,
which results in parallel, angular or skewed shaft misalignment. Parallel
misalignment occurs when shafts' axes are parallel to one another, but
do not intersect with one another. Angular misalignment occurs when the
axes of shafts intersect with one another at an angle. Skewed misalignment
occurs when axial and angular misalignment occur in conjunction with
one another. Flexible shaft couplings provide the means by which rotating
equipment can continue to function during moderate displacement measuring
up to 5° of misalignment.
In addition to transmitting torque and accommodating shaft misalignment,
flexible shaft couplings perform other functions. Flexible shaft couplings
accommodate axial displacement. Axial displacement, also called end float,
occurs when the shafts move along the axis of rotation, either toward
or away from one another. Flexible shaft couplings also provide shock
absorption and lessen the intensity of vibrations, a process known as
damping.
Numerous types of flexible shaft couplings exist. Correct flexible coupling
requires careful analysis of the industrial application and environment
in which the coupling will be used, and the performance of individual
couplings. Certain flexible couplings are better suited than other flexible
shaft couplings for a particular application. Flexible shaft couplings
are categorized according to their means of flexibility and their application.
Three types of flexible shaft couplings exist: mechanical flexible shaft
couplings, elastomeric flexible shaft couplings, and metallic membrane
flexible shaft couplings. Not all manufacturers of flexible shaft couplings
create all three types. Certain manufacturers can make custom flexible
shaft couplings for rare or odd connections.
Types of Flexible Shaft Couplings Including: Universal
Joints, Shaft Couplings, Flexible Couplings, and Gear Couplings.
Compression couplings
offer several advantages, which include efficient torque transmission,
high overload tolerance and high torsional stiffness. Compression couplings
include jaw couplings, pin and bush couplings and donut couplings.
Diaphragm couplings permit angular misalignment, but only a small
degree of axial motion. A sub-type of metallic membrane coupling.
Disc couplings accommodate angular misalignment, but do not accommodate
parallel misalignment or axial motion. A sub-type of metallic membrane
coupling.
Drive shafts transmit torque from engines to moving parts.
Elastomeric couplings
contain a resilient element, such as rubber or plastic. Elastomeric
couplings possess many advantages, including a high damping ability,
high shock absorption, a high degree of misalignment accommodation,
and do not require lubrication; however, elastomeric couplings are larger
than metallic couplings, and possess sensitivity to ultraviolet light,
chemicals and high temperatures.
Fail-safe couplings
are designed to continue operating for a certain length of time after
the application of torque has ceased.
Flexible couplings transmit power while compensating for any misalignment.
Gear couplings
offer efficient torque transmission in a compact mechanism, and permit
a high degree of axial movement. However, gear couplings require piloting,
and may malfunction at very high or very low torques.
Grid couplings
offer adequate vibration damping and shock absorption. However, significant
axial movement may compromise coupling resilience.
Mechanical flexible
couplings obtain flexibility through loosely fitted parts that
move past one another. Mechanical flexible couplings maintain high torsional
stiffness and accommodate a high degree of angular misalignment; however,
mechanical couplings require lubrication and maintenance, and may not
permit adequate axial movement.
Metallic flexible couplings
do not contain a rubber or a plastic element. Metallic flexible
couplings offer high torsional stiffness and great resistance to chemicals,
ultraviolet radiation and high temperatures.
Metallic membrane or
metallic element couplings obtain flexibility through the bending
of a membrane within the coupling. Metallic membrane couplings require
low maintenance and no lubrication; however, these couplings may be
more expensive than mechanical flexible couplings.
Shear couplings
provide a high degree of misalignment accommodation, produce low reactionary
loads and offer high torsional softness. Shear couplings include tire,
sleeve and molded-element couplings.
Common Terms Related To Flexible Shaft Couplings
Including: Universal Joints, Shaft Couplings, Flexible Couplings, and
Gear Couplings.
Angular Misalignment
- The condition in which the axes of shafts intersect with one another
at an angle; angular misalignment is calculated by measuring the angle
at the intersection of the connected axes, expressed in degrees.
Axis of Rotation - An imaginary line in the center of an object
around which the object rotates.
Axial - Characterized by movement along the axis of rotation.
Axial Displacement - Condition in which shaft's move axially; also
called end float.
Axial Freedom - The amount of movement along the shaft axes that
a coupling can permit.
Axial Stretch - The change in a shafts length, whether an increase
or decrease in length, upon the application of a load.
Backlash - The extent of shaft movement.
Bending Flexibility - Measurement indicating the comparison of
flexibility between shafts.
Bending Stiffness - The shaft's resistance to the application
of torque.
Bore - The hole on the shaft onto which the coupling is mounted.
Burst Pressure - The pressure at which a device fails and loses
ability to retain fluid.
Damping - The reduction of vibration between shafts; this reduction
is caused by an elastomer in the coupling.
Field Repairable - In such cases the entire coupling does not have
to be replaced and only certain components are repaired on site of the
coupling.
Horsepower (hp) - Measurement
unit indicating the time rate of work a piece of equipment produces. With
regard to mechanical power, horsepower equals the movement of 33,000 pounds
one foot per minute or the movement of 550 pounds one foot per second.
Horsepower equals 746 watts of electrical power.
Hysteresis - A delay in the response of an object to forces, especially
magnetic forces, acting upon the object; often observed in elastic and
magnetic objects.
Inherent Balance - Balance of
the coupling found in the original design of the coupling itself. This
also can be a factor of the materials used in construction of the coupling,
as certain stocks of metal are better for equilibrium.
Keyway - Rectangular opening in the coupling bore in which a key
may be inserted to lock couplings and shaft parts into place.
Parallel Misalignment - The condition in which shafts axes are
parallel, but do not intersect with one another; also called parallel
offset or radial misalignment.
Piloting - The process of guaranteeing that shafts and couplings
maintain the same axis of rotation.
Reactionary Load - The coupling's
exertion of force upon shafts during parallel misalignment, which causes
the shafts to bend.
RPM (Revolutions Per Minute) -
Measurement of operating speed indicating the number of full rotations
a shaft completes in one minute.
Shear Pin - A protective pin used in some couplings to prevent
cut off.
Shrouded Bolt - An optional
bolt found on some flexible couplings, which are used during high speed
applications. Installed with a socket wrench.
Thermal Expansion - Lengthening

Torque - The measurement of the extent to which a force applied
to an object causes the object to rotate.
Torsional Softness - The low
resistance of a shaft to twisting motion, opposite of torsional stiffness.
Torsional Stiffness - The measurement of a shaft's resistance
to twisting during operation. High torsionsal stiffness indicates minimal
shaft twisting; low torsional stiffness indicates little resistance to
twisting.
Torsional Vibration - The change in a rotational system's
torque.
