Flexible shaft coupling element and flexible couplings incorporating same

摘要

A flexible shaft coupling element comprising a sleeve shaped body having a central annular portion and a coupling receiving portion at each of two opposing sleeve ends. The coupling receiving portions include axially extending teeth on their inner surfaces. The flexible shaft coupling element is characterized in that the annular portion possesses a torsional shear capacity and the area defining the axially extending teeth possesses a shear capacity, and the tooth shear capacity exceeds the annular portion torsional shear capacity.
