For spacer shafts the table gives the maximum allowable offset for 1 . inch of spacer shaft length. For example, a machine running at 1800 RPM with 12 inch of spacer shaft length would allow a maximum offset of 0.6 mils/inch x 12 inches = 7.2 mils at either coupling at the ends of the spacer shaft. Angular Misalignment - an overview ScienceDirect TopicsAngular misalignment between two shafts connected with a flexible coupling introduces an additional driving force that can produce torsional or lateral vibrations. The forces in a typical industrial coupling are similar to those in a universal joint (Figure 18-2).When a small angular misalignment occurs, the velocity ratio across the joint is not constant. Are you using coupling tolerances to align your machines? The Lovejoy S-Flex coupling (not shown) is also a short flex coupling and the offset and angle are given in their misalignment capability guide for each coupling Parallel, the S-flex Endurance coupling accepts up to .062 inches of parallel misalignment. Angular, the S-Flex Endurance coupling accepts angular misalignment up to 1 degree.
