Motor Couplings
Motor couplings exhibit high torsional
stiffness which prevents system resonance. There are five main types of
flexible shaft couplings that are used for motor applications: beam,
Oldham, jaw, disc and bellows.
Components of motor couplings are mostly made out of metal like steel,
stainless steel and aluminum. Certain parts, like the spider in jaw
couplings, are made of polyurethane or other plastic resin-based
materials. Each motor coupling has different degrees of torque, shaft
misalignment, stiffness, rotations per minute and space requirements
and these factors must be taken into account when choosing a coupling
for a motor application. Motor couplings are used in medical systems
like scanners, DNA analyzers and x-ray equipment, as well as home
appliances like blenders, dishwashers and washing machines.
The
five kinds of motor couplings are different in size, shape and
characteristics. Beam couplings have zero backlash and are machined
with several spiral cuts to absorb impact. Oldham couplings have high
parallel misalignment capabilities while jaw couplings are best for
shock absorption because of their plastic dampening component called a
spider. It serves to dampen impulse loads and minimize shock to a
motor. These couplings are considered fail safe because if the spider
malfunctions, the jaws of the two hubs interlock and create direct
power transmission so the vehicle can shut down safely. Jaw couplings
perform the best for applications that use a stop-and-go type of
movement that also require accuracy; they are not optimal for
applications in which precise movements are required during movement.
Disc couplings are torsionally rigid and therefore have high
misalignment capability. Bellows couplings offer the most rigid
torsional stiffness. They offer a near-infinite life span and are
virtually maintenance free. Their connection is hidden within the
fit-length of the hub, enabling exact transmission of angular motion
and torque. One of the most common methods of construction for motor
couplings is electroforming where the part is built by adding layers of
metal on a mandrel until the desired thickness is reached. Another
method is mechanical forming such as roll-forming or extrusion. Welded
couplings are made by welding a series of rings or washers inside and
outside.
