ABSTRACT:
A power transmission device of a press machine comprises a rotary shaft rotated around a first axis by the rotation of a flywheel and an arm mounted on the rotary shaft and pivotally connected to a first link. A second link is pivotally connected to the first link so as to be rotated around a second axis, eccentric from the first axis, by the rotation of the arm. A lever is pivotally connected to the second link so as to be rotated around the first axis by the rotation of the second link and is also connected to a crankshaft so as to rotate the crankshaft. A rotor and guide constrain the rotary motion of the second link relative to the second axis to movement along a hypothetical circle centered on the second axis. The second link is engaged with the rotor at an engagement portion moved along the hypothetical circle in accordance with the rotation of the second link, whereby a uniform rotary motion is converted into a non-uniform rotary motion without using any gear and without making rotation axes of input and output shafts eccentric from each other.
