BALANCING MECHANISM FOR PISTON MACHINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: mechanism has a disk fitted on the second shaft whose speed of rotation is less by half than speed of rotation of a crankshaft. The disk is provided with mutually perpendicular guides wherein counterweights are received. The counterweights engage with an inner profiled surface of a stator made of a heart-shaped curve. Four points of a curve which is equidistant to the heart-shaped curve are arranged in periphery direction in series and an angular distance between them is equal to 90. The points are located at the same distance from the center of the stator which is coincident with axis of the disk. One part of the heart- shaped curve is located out of the periphery and the other one inside the periphery. When the disk rotates, common center of masses of the counterweights reciprocates with a frequency which is grater than the speed of rotation of the disk by factor 4 and is twice speed of rotation of the crankshaft. EFFECT: expanded functional capabilities. 5 cl, 7 dwg
