Abstract

See full text

The invention relates to a method for the impact treatment of transition radii (8) of a crankshaft (4, 4′), in particular transition radii (8) between connecting rod bearing journals (5, 5′) and crank webs (7, 7′) and/or transition radii (8) between main bearing journals (6, 6′) and the crank webs (7, 7′) of the crankshaft (4, 4′). The crankshaft (4, 4′) is then rotated along a rotational direction into an impact position by means of a drive device (3, 3′). A locking device (12) is provided in order to lock the crankshaft (4, 4′) in the impact position, and an impact force is then introduced into at least one transition radius (8) by at least one impact tool (16, 16′).
