ABSTRACT
One of the most important components of any drive system is the device connecting the
rotating shafts together known as coupling. As it is nearly impossible to maintain perfectly
collinear centerlines of rotation between two or more shafts, flexible couplings are designed to
provide a certain degree of yielding to allow for initial or running shaft misalignment. There is
a wide assortment of flexible coupling designs, each available in a variety of sizes to suit
specific service conditions.
