Flexible couplings can also be known as elastic couplings. These couplings tend to have an elastic section between the ends of the coupling. There are a number of flexible couplings unique in construction made specific to applications. Flexible couplings are designed to transmit torque while allowing radial, axial, and angular misalignment. Flexible couplings can compensate for angular misalignment up to a few degrees and some parallel misalignment.

As a requirement of good shaft alignment, flexible couplings should be easy to connect or disconnect. The transfer of power from one shaft to the other should not incur any loss. Flexible couplings allow misalignment between two adjacent shafts. The goal is to minimize the remaining misalignment in running operation to maximize the power transmission and to maximize machine runtime while utilizing flexible couplings.

Flexible couplings can protect machinery from wear and premature breakdown. Flexible couplings can play a large role in extending the life of a components attached to the coupling and at the same time, not degrading the performance of the machine. Flexible couplings should have a proper fitting and this is sometimes overlooked which can be critical to machine design quality.

Flexible Couplings call for a regularly scheduled inspection, but maintenance is relatively easy. Inspections include:
•Performing visual inspections, regularly cleaning of flexible couplings as well as analyzing them for signs of wear and fatigue.
•If the flexible couplings are lubricated, checking and changing the lubrication annually. Some flexible couplings should be checked more often if they are used in adverse environments or in demanding operating conditions.
•Dating and documenting maintenance that is performed on each flexible coupling.

Flexible Couplings can fail even with proper maintenance. The main reasons for flexible couplings failure consist of:
•Inaccurate or improper installation
•Inadequate selection of flexible couplings
•Operation above the capability of the flexible couplings design

Understanding the problem of what caused a failure and correcting it before installing new flexible couplings can improve the overall flexible couplings life. Some things to look for that signifies future flexible couplings failure include:
•Abnormal noise, including screeching, squealing or chattering
•Extra wobble or vibration
•Lubrication leakage or contamination by means of failed seals

Flexible couplings are usually balanced at the factory before they are shipped, but every once in a while they go out balance during operation. Re-balancing flexible couplings can be expensive and difficult; it is usually only done when operating tolerance effort outweighs the expense. The characteristics of the specific connected machines dictate the amount of flexible couplings unbalance that can be tolerated by any system; this can be determined by experience or detailed analysis.

Love Joy Couplings are mechanisms used to connect two different motor shafts within a single application. It can be used as a means to connect two different systems, to repair a single system’s connection, or to reduce shock or wear between two shafts. There are two options that can be used to join a system: rigid or flexible couplings. Flexible couplings allow for some movement between the shafts, while Love Joy Couplings are used when precise alignment and a secure connection are needed. Love Joy Couplings help maximize a machine’s performance by holding the shafts tightly in place, and keeping them perfectly aligned. This also extends the machine’s expected lifetime. There are two different types of Love Joy Couplings: Sleeve-style couplings, or clamped Love Joy Couplings. The cost-effective and easy to use, Sleeve-style couplings consist of a single tube, with an inner diameter that is equivalent to the shaft size. The material that makes up the sleeve slips over the two shafts so they meet at the coupling’s midpoint. Set screws can be tightened to touch the top of each shaft, in order to prevent an individual shaft from passing all the way through the coupling and ensure the two meet in the middle. The second type of Love Joy Couplings are Clamped, or compression Love Joy Couplings. These couplings entail two pieces that fit around the shafts of the motor to form a sleeve. These Love Joy Couplings can be used on fixed shafts, and are a bit more flexible than a sleeve-style coupling. They have set screws that can pass through the entire coupling, in order to ensure a firm hold. For industrial applications with heavy loads, Flanged Love Joy Couplings are recommended. These Love Joy Couplings have short sleeves surrounded by a perpendicular flange. Each flange faces each other, with a coupling on each shaft. Screws and bolts can be added to hold the two flanges together. Flanged components can align shafts before they are joined, due to their durability and size. When exact shaft alignment is needed for an application, typically Love Joy Couplings are used. When a shaft is misaligned, both the coupling’s performance and lifespan are affected.
