  • Kop-Flex Coupling Selection and Design - Regal Beloit

    Since the center of gravity is moved closer to the bearing, the overhung moment is reduced, directly affecting the lateral critical speed (LCS) of the train. The larger the overhung moment, the lower the LCS. Given the adjustability of the coupling design, it is typically the most convenient and lowest cost location to tune the drive train.

  • Flexible Couplings - an overview | ScienceDirect Topics

    The purpose of a flexible coupling is to transmit torque from one piece of rotating equipment to another, while accepting at the same time a small amount of misalignment. Flexible coupling misalignment is expressed, as an order of magnitude, in thousandths of an inch. Actual misalignment, expressed in coupling terms, is angular in nature and expressed in angular units, that is, degrees.
