A crankshaft the crankpin consisting of a ring which has a throw variable from zero to several millimeters, and can transmit a relatively high torque value and withstand considerable stress applied at variable angles without buckling while permitting any desired adjustment of the crankpin throw during the crankshaft operation. The crankshaft comprises to this end a two-section hollow shaft with an intermediate rod engaging the bores of the shaft sections and, between these sections, a crankpin forming ring having a longitudinal cavity of elongated cross-sectional configuration and a width at least equal to the rod diameter and a major dimension at least equal to this diameter ; a diametral pin is locked to this ring by an outer sleeve which pin engages an oblique port formed in the rod whereby a change in the throw of the crankpin-forming ring is obtained by causing an axial movement of the rod. |
