Abstract

See full text

The invention relates to a method for the impact treatment of transition radii (8) of a crankshaft (4), in particular transition radii (8) between connecting rod bearing journals (5) and crank webs (7) and/or transition radii (8) between main bearing journals (6) and the crank webs (7) of the crankshaft (4). In order to apply an impact force (FS) to at least one of the transition radii (8) along the respective transition radius (8) circulating about the crankshaft (4) in an annular manner, a heavily loaded region (BMAX), a lightly loaded region (BMIN), and intermediate regions (BZW) lying therebetween are defined, and an impact treatment is then carried out such that the impact force (FS) introduced into the intermediate regions (BZW) is increased in the direction of the heavily loaded region (BMAX).
