    Abstract: The crankshaft of a piston engine is assembled with a vibration damper into a discrete module prior to mounting of such module in axial and/or radial bearings of the housing of the engine. The damper has an input element which rotates with the camshaft and a mass which is angularly movable relative to the input element against the resistance of coil springs. The input element can be provided with a sleeve which surrounds a snout at one axial end of the crankshaft. Alternatively, the damper can be installed in or on or can constitute a cheek of the crankshaft. The coil springs can operate in parallel with a friction generating device which also opposes rotation of the input element and the mass of the damper relative to each other.

    Abstract: A flywheel capable of accommodating various automotive engines and transmission systems having different points of balance. The flywheel has a hub portion for securing to a crank shaft output arbor and a web portion integral with said hub portion on the periphery of said web portion and a weight is secured to the flywheel in such a way that the effective weight and effective position thereof is adjustable to a plurality of discrete positions, each of which is precisely correlated to each of the different points of balance of said various automotive engines having different points of balance, respectively. In a preferred embodiment, the weight is angularly and radially adjustable and is guided to each discrete position by at least one slot formed in the web, and a bolt passing through said weight and the slot. The bolts passing through the slots have safety attaching indentations therein for non-slip positive attachment of the weight in the different positions. An adaptor ring press is fitted within a hole in the hub for accommodating different output arbors of engine crank shafts and the adaptor ring and hub have cut-outs forming an elongated alignment slot for an alignment pin on the crank shaft arbor. A hole or aperture formed 180 degrees opposite the slots has an area of sufficient size as to provide a neutral balance condition when said weight means has been removed therefrom.

    Abstract: A crankshaft for a 90.degree. V-type eight-cylinder internal combustion engine having eight balance weights of No. 1 through No. 8 balance weights and supported by five supports. An angle defined between the No. 1 and No. 2 balance weights is set at the range of 15.degree.-45.degree. and an angle defined between the No. 1 and No. 3 balance weights is set at the range of 45.degree.-75.degree.. The mass of each of No. 1 and No. 8 balance weights is greater than the weight of any one of No. 2 through No. 7 balance weights. These relationships can reduce the weight of a crankshaft and bearing loads.

    Abstract: In power presses such as are used for stamping sheet metal and the like, the inertia forces of the reciprocating slide of the press and its attached parts set up very heavy and objectionable vibrations, particularly in high speed presses. The present invention provides primary and secondary counterweights. The primary counterweights rotate with the crankshaft or eccentric shaft of the press but with the center of gravity of the counterweight moving in a direction opposite to the direction of movement of the slide to neutralize at least a portion of the inertia forces of the slide and its connected parts. The secondary counterweight rotates opposite to the first counterweight but with its center of gravity moving in the same direction with respect to the vertical, so that the second counterweight has a cumulative effect with respect to the primary counterweight in neutralizing vertical inertia forces but has a subtractive effect with respect to lateral inertia forces produced by rotation of the primary counterweight.
