ABSTRACT:
In a device which provides a coupling between an electric motor and an element which is driven in rotation at very high speed and suspended from a connecting-rod which works in traction, the diameter and length of the connecting-rod are determined in respect of a given weight of the driven element and a given torque so that the ratio of the length to the diameter of the connecting-rod is higher than 50 and preferably between 90 and 200. The result thereby achieved is a minimum value of the natural frequency of the connecting-rod and maximum transverse stability.
