Estimating the term…
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).
A method for the impact hardening of transition radii of a crankshaft, in a particular of transition radii between connecting-rod bearing journals and crank webs and/or transition radii between main bearing journals and the crank webs of the crankshaft for the introduction of an impact force into at least one of the transition radii, wherein a highly loaded region, a lightly loaded region and interposed intermediate regions are defined along the respective transition radius running in annularly encircling fashion around the crankshaft, wherein impact hardening is performed such that the impact force introduced into the intermediate regions is increased in the direction of the highly loaded region, wherein the impact head of the at least one impact tool introduces the impact force into the transition radius at an adjustable impact angle.
