  • Alignment and Installation

    Flexible Shaft Couplings Shaft couplings are extremely invaluable in protecting machinery from stress, wear, and thus, untimely failure. This is because they often significantly lengthen the working life of the parts they connect. In precision applications, flexible couplings are compensating for three axes of shaft misalignment, while accurately transmitting velocity, position, and torque. Because of their important role, it is crucial that they are selected carefully and installed properly. Even though the flexible shaft coupler is able to compensate for misalignment, it is imperative to align the shafts as much...

  • The Third Shaft

    Flexible Shaft Couplings When I was a child, one of my favorite television shows to watch was School House Rock. On this delightfully musical and educational show was a song called Three is a Magic Number , and this is a statement I have always found stands true, even when it comes to the industrial world. For example, the third shaft, which is also sometimes known as the flexible gear coupling or gear coupling, is so vital to the proper running of a machine or vehicle it can be considered...

  • The Building Block Products of Renewable Energies

    Flexible Shaft Couplings With all of the hype involving oil and its related issues, both environmentally and economically, a focus on renewable energies has developed and continues to be a focal point for many industrial arenas. A variety of products are being developed specifically for renewable energy efforts, and some that are already in existence are simply being newly applied, like the shaft coupler. These shaft couplings are used to help transfer power from the source to what it is moving, easing the stress on the two shafts that connect...

  • Flexible Shaft Couplings: The Fluid Version

    Flexible shaft couplings are designed to secure rotary equipment to its stationary counterparts while removing some of the stress from the mechanical parts and correcting misalignment when it happens. Fluid couplings are a certain type of shaft coupling that is particularly special because it is a flexible shaft coupling that is a hydrodynamic device, which can not be claimed by any other coupling model. Hydrodynamic means that fluid couplings utilize liquids, usually oil to translate the movement of one part into power for another, while also maintaining some of the...

  • Bellows With A Twist - Electrodeposited nickel bellows couplings flex to fit misaligned shafts yet remain torsionally stiff.

    Electrodeposited nickel bellows couplings flex to fit misaligned shafts yet remain torsionally stiff. by Paul Hazlitt, Senior Engineer Servometer - PMG, LLC What do a micron-precision silicon wafer cutter, a surgical microscope focusing mechanism, and a target sighting system for an MIA2 Abrams tank all have in common? Each contains an electrodeposited nickel bellows coupling. Such couplings excel in instrumentation and fractional-horsepower applications but are occasionally overlooked because they tend to cost more than other types. Couplings are typically rated by their torque capacity, rotational inertia, resistance to the elements,...

Flexible Shaft Couplings

A flexible shaft coupling is a device that connects two shafts that can transmit torque even if misaligned. In ideal circumstances, shafts are connected by a coupling to form a straight line. However, two shafts can become out of line as the result of poor installation, thermal growth or shrinkage, foundation movement or component wear.

A flexible shaft coupling is needed to connect shafts that are slightly misaligned. In parallel misalignment, two shafts are virtually parallel but slightly offset. In angular misalignment, the shafts intersect at angles to each other. Axial misalignment is a combination of both parallel and angular misalignment. 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. The most common materials for flexible shaft couplings in automobiles are stainless steel, which protects against corrosion and increases torque capacity and strength, and aluminum, which is a lighter and less expensive option. Certain types of flexible shaft couplings contain a central disk comprised of plastic or rubber that transmits torque. Flexible shaft couplings are cylindrical in shape, and vary depending on the different types and their functions. Flexible shaft couplings are used to connect drive shafts in automobiles; they isolate driveline vibration, propeller pulse, and gear chatter in motorized boats. Other industrial applications include use in printing machines, paper making machines, roll forming machines, hydraulic pumps, and wind turbines.

There are many different kinds of flexible shaft couplings. The Oldham coupling consists of three components: two hubs and a central plastic disk. It accommodates slight parallel misalignment, while providing almost zero backlash. Backlash is the amount of lost motion due to clearance or slackness when movement is reversed and contact is re-established. The bellows coupling has two hubs and a thin walled metallic bellows and can accommodate all three types of misalignment. Single beam couplings are usually made of a single piece of aluminum and have a system of spiral cuts that allow it to bend in order to accommodate angular misalignment. Multiple beam couplings consist of two to three overlapping beams that address problems of torsional rigidity. Jaw, or spider, couplings consist of two metallic hubs, each with a set of interlocking teeth, and a flexible rubber or plastic piece (the spider), in the shape of a star which fits between them. Jaw couplings have zero backlash and function well at high speeds but do not tolerate a great deal of misalignment. A single disc coupling is composed of two hubs that bend to accommodate angular misalignment. The double disc coupling has two hubs that are connected by an additional center spacer that allows them to bend in opposite directions to manage offset shafts.
