ABSTRACT:
Flexible shaft assembly includes a central flexible shaft having its ends permanently affixed within axial bores provided in a pair of end fittings. The end fittings are also provided with a plurality of outer bores disposed symmetrically around the axial bores for receiving the ends of a plurality of outer flexible shafts. At least one end of an end fitting's outer bores receives the ends of one end of the outer flexible shafts in free-floating relationship enabling the assembly to maintain substantial symmetrical disposition of the shafts even when rotating in a tight radius of curvature while transmitting high torques. Bearing supports however may be required to maintain the rotating flexible shafts along a predetermined tight path. By selecting shafts of proper lay, i.e., right-lay and left-lay, the entire assembly may be substantially torsionally balanced.
