Abstract
A method of assembling a universal joint comprising two shafts provided with yokes at their ends and connected by means of a universal joint spider having journals supported in bores in the yokes by bearing cups which are unilaterally closed by a bottom wherein the end faces of the journals abut against the bottoms of the bearing cups, comprising initially centering the universal joint spider and the shafts relative to each other and stationarily clamped, then pressing the bearing cups in the bores in the yokes and axially fixed therein wherein the yoke arms, if necessary, are widened radially outwardly and are always immovably fixed radially inwardly, characterized in that the axial position for each bearing cup (6) in the respective bore (3) of the yoke (5) in which the bottom (9) of the bearing cup (6) abuts against the end face (34) of the respective journal (1) is measured or determined and the pressing process of the bearing cup (6) in this position is either terminated or based on this position, the pressing process is continued under elastic flexion of the bottom (9) of the bearing cup (6) by a defined dimension (f) wherein the pressing force acts upon the bottom (9) solely…
