LEVER-GEAR MECHANISM WITH TWO DWELLS OF THE DRIVEN LINK

Click to enlargeClick to enlarge Description

Gear 1 rotates about fixed axis A and meshes with gear 4 which rotates about fixed axis E. Gear 1 is connected by turning pair B to link 2 which, in turn, is connected by turning pairs C to links 3 and 5. Link 3 is connected by turning pair D to gear 4, and link 5 is connected by turning pair F to link 6 which turns about fixed axis G. The dimensions of the links comply with the conditions: A͞B=r, B͞C=C͞D=2.9r, C͞F=2.6r, D͞E=0.3r, F͞G=2.5r, A͞E=2.2r, A͞G=3.2r, E͞G=1.5r, r₁=1.5r and r₄=0.75r, where r₁ and r₄ are the pitch radii of gears 1 and 4. When driving gear 1 rotates, point C describes complex connecting-rod curve q whose portions a-a and b-b approximately coincide with circular arcs of radius C͞F=2.6r described from the corresponding positions of point F. In each full cycle of motion, driven link 6 has two long dwells during the time that point C passes over portions a-a and b-b of its path.
