Hysteresis Energy Caracteristic of SEGME-type in Flexible Coupling

The object of the study are representatives of the flexible couplings of the SEGME series, designed for a nominal torque of 25 Nm and 63 Nm. The amount of energy lost in the process of internal friction is determined on the basis of an experimentally recorded dynamic characteristic of the corresponding coupling. The load and unload lines from the characteristic are described by polynomials through regression analysis. The adequacy of the selected model was evaluated. The influence of the magnitude of radial misalignment on the energy determining the coupling’s damping ability was investigated. At the same levels of radial misalignment, a study was conducted on the influence of additional angular misalignment of the joined shafts. Recommendations are made for allowable two-dimensional misalignments of the drive and driven shafts.
