<p>A crank mechanism (10) for an internal combustion engine includes a connecting rod (11) extending to a piston. The mechanism (10) includes a support (12) which rotatably supports a primary shaft (13) for rotation about a longitudinal axis (14). Fixed to but spaced laterally to the primary shaft (13) is a link shaft (16) having a longitudinal axis (15). In operation, the shaft (16) together with its axis (15) rotates about the longitudinal axis (14). Rotatably supported on the shaft (16) is an external gear (17) meshingly engaged with a stationary internal gear (18). The gear (17) when driven rotates about the longitudinal axis (15) while the longitudinal axis (15) rotates about the axis (14) in the opposite rotational direction. This motion therefore causes rotation of the shaft (13) about the axis (14) in the opposite direction to the arrow.</p> |
