Abstract
A worm shaft is provided with an intermediate worm thread section between first and second end structures, wherein at least one of the first and second end structures has a coupling structure for a desired extension of a plurality of modular worm shaft extensions. The desired extension and the intermediate worm thread section are both selectable based on the desired application, the desired gearing ratio, and other features. Accordingly, the multi-component worm shaft of the present technique increases flexibility, reduces manufacturing costs, and reduces inventory.
