It has been carried out the analysis of stress-strain state of flexible element pack for flexible coupling as a result of the combined action of the forces from the torque transmitted by the coupling and the forces caused by misalignment of the coupled shafts. Plots of bending moments from external load and reactive forces arising in the flexible elements of the pack have been constructed. There have been obtained the analytical dependences of the deflections and rotations of the sections on the complex load. The effects of various force factors on the stress-strain state of a flexible element have been compared. Directions of increasing the fretting resistance of the flexible elements are proposed.
