    Abstract: When each of the crank arms is divided by the crank arm centerline-into a right arm portion and a left arm portion, an area moment of inertia of one of the right and the left arm portions that is in a side that is subjected to the maximum load is greater than an area moment of inertia of the other arm portion that is in a side opposite to the side that is subjected to the maximum load, and, the area moment of inertia of the arm portion that is in the side opposite to the side that is subjected to the maximum load is greater than the area moment of inertia of the arm portion that is in the side that is subjected to the maximum load.

    Abstract: A bumper for a pendulum that cannot inadvertently become loose is disclosed. The pendulum has at least one and preferably a pair of spaced apart, elongated bumpers. The elongated bumpers generally have an L-shape. The pendulum is comprised of two halves. L-shaped channels are formed in each pendulum half. The bumpers are fitted into channels of the same shape formed in the pendulum halves. When the two halves are fitted together, the L-shaped bumper is captured therebetween. Each pendulum half includes an elevated central area and a pair of recessed areas with each recessed area formed on one side of the elevated area. Side walls are formed at the intersections of the elevated area and the recessed areas. A base wall is formed along the lower edge of the elevated area. The bumper ends extend from the elevated area beyond the side walls and base wall.

    Abstract: A crankshaft for an internal combustion engine having a core formed from a first material and an outer layer formed from a second material, the second material being different from the first material, is disclosed. Both the first and second materials are preferably though not absolutely metals. The crankshaft core is preferably formed from forged steel, such as C1117 AISI or similar steel. The layer formed over the crankshaft core is preferably iron, such as nodular iron. The crankshaft core is preferably formed having an orienting keystone lock at each end. The iron layer formed over the crankshaft core may be of a variety of irons, though nodular iron is preferred. The disclosed crankshaft thus provides an alternative to the traditional forged steel crankshaft by utilizing a low cost, forged steel core and cast a nodular iron outer layer that includes the counterweights, cheeks, post, flange and journals.
