The gear (1) has a crank hinge pin (4) inserted into small eyes (3) of a connecting rod (2) of the gear and designed as a cradle joint (5) that comprises two cradle pieces (6, 7). The cradle pieces exhibit equal cross-section, and the small eyes comprise a guide contour that is directly molded or machined. The cradle pieces are guided through a guide bush that comprises an anti-twist plate and is formed as a sintered part. The hinge pin comprises an axial locking device (11). The small eyes are spaced from each other and arranged next to each other along the hinge pin.
