    摘要： A balance system for an internal combustion engine or the like includes a counterbalance weight pivotally mounted to the crankcase and driven in a reciprocating manner by a link assembly connecting the weight to an eccentric on the crankshaft. The pivoting weight not only counterbalances the piston acceleration and deceleration forces but also cancels the torsional forces created by the weight as it pivotally moves through an arc in response to piston movement. This is accomplished by locating the center of gravity of the balance weight between the piston bore centerline and the stationary pivot of the balance weight itself. This location for the center of gravity causes a torque to be generated by a force couple created by the piston inertial force vector, the balance weight interial force vector, and the distance between them. This torque counteracts the torque generated by angular acceleration of the balance weight itself, to thereby substantially eliminate all torsional vibrations.

    摘要： An engine-balancing system for balancing the primary forces of single cylinder and in phase in-line multi-cylinder piston engines. The balancing system includes rotary, auxiliary counterweights mounted on the exterior of the engine block for rotation about fixed axes that are parallel to and spaced from the crankshaft axis and positioned at diametrically opposite sides thereof. The combined centrifugal forces of these auxiliary counterweights are preferably equal to that of the conventional crankshaft-carried counterweights. The auxiliary counterweights are drivingly-connected with the crankshaft by a flexible double-sided timing belt that is trained over sprockets of the same diameter coaxially fixed with respect to the crankshaft and with each of the pair of auxiliary counterweights so that the pair of auxiliary counterweights turn at the same speed as, but in the opposite direction from that of the crankshaft. The auxiliary counterweights coact with one another and with the conventional crankshaft-carried counterweight to significantly diminish vibration of the engine incident to its operation.
