Stress–strain behavior and specific friction of toric rubber-cord casings of flexible couplings

Abstract

The results of experimental studies of stress–strain behavior during hardening stages, as well as the stabilization and strength degradation of the rubber-cord casings during the static loading mode have been given. The influence of measurements of these characteristics on the drive dynamic loading has been shown. The physical processes of specific friction in the coupling flexible element have been considered. Dependence diagrams of the specific friction on dynamic torque, vibration frequency, torsion angles, and casing temperature have been made.
