Structure of mechanism |
| Function |
A manually powered winch has two geared drive trains. Both originate from a simple set of gear teeth (7) formed into the diameter of a drive input shaft (5). The final drive, common to both gear trains, to an internal gear track (18) on the drum (3) of the winch is one part (12) of a two part gear (8,12). The part (12) is directly borne by a hub (20) on an axle (10) in the winch. Its gear teeth are on the outer face of an annulus (22) on the inner face of which are ratchets (14) of a pawl-and-ratchet unidirectional drive (16) between the two parts (8,12). The other part (8) of the two-part gear is preferably borne not directly on the axle (10) but on the hub (20) of the part (12). |
