A Study of the Dynamic Stiffness of Flexible Couplings with a Rubber–Metal Element Type SEGME

Abstract

The dynamic characteristics of flexible couplings with a rubber–metal element type SEGME have been studied. The hardness of the rubber element of the SEGME 25 coupling is 53 Shore A, and that the SEGME 63 coupling is 73 Shore A, respectively. The experimental study was carried out in conditions of alignment of the connected shafts, and also at different levels of radial misalignment. The influence of an additional angular misalignment was investigated. The results show that, for this coupling type, the radial misalignments induce a downward nonlinear dependence on the dynamic stiffness. The presence of a small angular displacement in the shafts causes significant radial deformations. The sensitivity of the coupling decreases with the high hardness of the rubber element.
