Abstract

PURPOSE: To reduce diameter of a driving gear by using a distance ratio of 0.4 W0.6 between an eccentric distance of an eccentric pin, which is provided on the driving gear, and a distance from center of the driving gear and center of a crankshaft.
CONSTITUTION: A driving pinion 3 is fit in a driving shaft supported on a frame of a press. A driving gear 4 to be engaged with the driving pinion 3 is supported on the frame in free-to-turn arrangement. The driving gear 4 is provided with a pin 6 with a shaft at a position of an eccentric distance R. A crankshaft 9 is equipped with a lever 8 for sliding of a slider 7 on the pin 6. At this time, an angle to be formed by a line drawn from O in parallel with O'C and O-O line 45° and the ratio between O-O' line and the aforementioned R is to become 0.4W0.6.
