Motor Couplings

Motor couplings are flexible devices that provide distance changes along a lateral axis between a motor shaft and a device. Flexible shaft couplings are necessary to connect shafts that are slightly misaligned. The degree of misalignment a coupling can tolerate depends on its material and its application but in general, up to 5° of misalignment can be tolerated. Although they vary significantly, motor couplings are always composed of an outer casing with an axis and two sides and a carriage shaft, where a carriage moves sideways along an axis of rotation and is surrounded by ball bearings.

Motor couplings exhibit high torsionalstiffness which prevents system resonance. There are five main types offlexible 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 jawcouplings, are made of polyurethane or other plastic resin-basedmaterials. Each motor coupling has different degrees of torque, shaftmisalignment, stiffness, rotations per minute and space requirementsand these factors must be taken into account when choosing a couplingfor a motor application. Motor couplings are used in medical systemslike scanners, DNA analyzers and x-ray equipment, as well as homeappliances like blenders, dishwashers and washing machines.

Thefive kinds of motor couplings are different in size, shape andcharacteristics. Beam couplings have zero backlash and are machinedwith several spiral cuts to absorb impact. Oldham couplings have highparallel misalignment capabilities while jaw couplings are best forshock absorption because of their plastic dampening component called aspider. It serves to dampen impulse loads and minimize shock to amotor. These couplings are considered fail safe because if the spidermalfunctions, the jaws of the two hubs interlock and create directpower transmission so the vehicle can shut down safely. Jaw couplingsperform the best for applications that use a stop-and-go type ofmovement that also require accuracy; they are not optimal forapplications in which precise movements are required during movement.Disc couplings are torsionally rigid and therefore have highmisalignment capability. Bellows couplings offer the most rigidtorsional stiffness. They offer a near-infinite life span and arevirtually maintenance free. Their connection is hidden within thefit-length of the hub, enabling exact transmission of angular motionand torque. One of the most common methods of construction for motorcouplings is electroforming where the part is built by adding layers ofmetal on a mandrel until the desired thickness is reached. Anothermethod is mechanical forming such as roll-forming or extrusion. Weldedcouplings are made by welding a series of rings or washers inside andoutside.
