Abstract
A shaft coupling for transmitting power including a flexible hollow rod extending in a longitudinal direction and having pairs of helical slots formed thereon. The pairs of slots are spaced from each other along the longitudinal direction of the rod. The shaft is manufactured by providing a hollow rod and advancing the rod with a combined rotational and translational motion. An opening is machined across a diameter of the rod during its advancement to form a pair of intertwined helical slots.
Claims8
A method of manufacturing a flexible shaft coupling comprising the steps of:
- providing a hollow rod with a longitudinal central axis;
- rotating said hollow rod around its longitudinal central axis, and moving said hollow rod in an axial direction;
- and
- machining an opening across a diameter of said rod during said step of rotating and moving to form a pair of intertwined helical slots.
