<p>A rotatable apparatus includes a pair of rotatable members joined by a stress dissipating structure. The stress dissipating structure can be employed in a gear (Fig. 20) (205), sprocket, clutch (Figs. 24-28) or the like. In one embodiment (Fig. 20) of the present invention, anti-buckling plates (211, 231) generally spanning between a hub (223) and rim (209) define a hollow cavity. In another embodiment (Fig. 45) of the present invention, the stress dissipating structure includes specifically configured sets of nodules (2301, 2303) between the hub (Fig. 42) (2071) and rim (2077). An additional aspect of the present invention provides a stress dissipating structure employing various anti-buckling plate attachment constructions. In still another embodiment of the present invention (Figs. 17-20; Fig. 40), a uniquely sized and packaged gear, gear housing and/or motor are employed in order to maximize output force per pound of material efficiences. Another embodiment employs a stress dissipation member in a door lock mechanism (Fig. 49).</p> |
