Abstract
This invention is a heavy-duty flexible shaft that accommodates for misalignments between an input and output shaft. The flexible shaft is comprised of a multiplicity of hollow, individually fabricated, interfitting members housed in a tubular, bendable shaft. Each segment is intimately engaged, one within the other, yet the segments are so designed to allow for limited longitudinal movement while restricting circumferential movement between segments during torsional transmissions from the input to the output shafts.
