A low-vibration crankshaft (16) has crankarms (31-38) of decreasing inertia/mass and stiffness as their distances from a torsional vibration node (54) of the rotating vibration system increases. The mass and stiffness of the crankarms (31-38) may be varied by changing the lateral width of the crankarms (31-38) or by other means. The arrangement provides, in combination with an engine or other reciprocating piston machine, an increased, maximized torsional vibration resonant frequency and results in lower, minimized angular deflections of the crankshaft (16) in the condition of system resonance. |
