Abstract
In a balance device for a mechanical press, a press body or frame rotatably mounts a crankshaft. A slide is supported from the crankshaft by connecting rods so that it reciprocates transverse to the axial direction of the crankshaft as the shaft is rotated. To avoid the development of an oscillating effect in the press body during operation a first gear is positioned on the crankshaft. Balancing gears are supported on the press body in meshed engagement with the first gear. Each of the first gear and the balancing gears has a balance weight for counteracting the tendency of the slide to cause oscillation and vibrations in the press body.
Claims6
Balance device for a mechanical press comprising a press body, an axially extending crankshaft rotatably mounted on said press body, connecting rods mounted on and spaced apart in the axial direction of said crankshaft, a slide attached to said connecting rods for reciprocal movement in a direction transverse of the axial direction of said crankshaft, a first gear positioned on said crankshaft for rotation therewith and positioned approximately midway between said slides, a plurality of balancing gears mounted on said press body, each of said balancing gears having the same number of teeth as said first gear with one of said balancing gears in meshed engagement with said first gear and located on the opposite side of said crankshaft from said slides and at least one other said balancing gear is meshed engagement with the one of said balancing gears and located on the opposite side of said one of said balancing gears from said crankshaft, balancing weights connected to each of said first gear and said balancing gears for counteracting the tendency of said slide to cause oscillation and vibration in said press body, and the center of said first gear and said balancing gears being aligned one above the other.
