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').

Disclosed is a method for increasing the strength of a part, especially a crankshaft, which is subject to torsional and bending stress. In said method, essentially the entire part is provided with a nitride layer in a first step, the nitride layer is at least partially removed in at least one highly stressed area of the part by means of a machining process in a second step, and the at least one highly stressed area of the part from which the nitride layer has been removed is mechanically work-hardened in a third step.

METHOD FOR INTRODUCING TRANSITION RADII INTO A CRANKSHAFT AND DEVICE FOR CARRYING OUT THE METHOD
In a method for introducing transition radii into a crankshaft (1) between crank pins (2) and crank webs (3) and/or between the bearing pins and crank webs, wherein the contour profile of the transitions (5) between the crank webs (3), the crank pins (2) and bearings (4) of the crank pins (2) and/or between the bearing pins (Ia) and the crank webs (3) has in each case at least two differently sized partial radii, the transition radii are introduced in a plurality of working steps. In a first working step, a mechanical abrasion process is carried out on a continuous radius (R1), subsequently, in a second working step, a strain-hardening is carried out with a second radius (R2), and, in a third working step, in a further mechanical abrasion process, final radii are introduced in the form of a main radius (R01) and at least one second radius (R02, R03) which adjoins the main radius (R01) and is smaller than the main radius (R01).

In a method for measuring unmachined parts (2), particularly unmachined large crankshafts (2a), prior to the finishing operation and for determining whether a dimensionally accurate finished part can be produced from the unmachined part (2) by the finishing operation, measured actual values are compared to desired values of a target contour of the finished part or a target contour of the unmachined part (2). By means of a scanning device (6), a plurality of points on the surface of the unmachined part (2) are captured simultaneously and joined to form a three-dimensional actual contour of the unmachined part (2) using a data processing device (8), with this contour then being compared to the target contour of the finished part or the target contour of the unmachined part (2).
The invention relates to a method for increasing the bending strength and the endurance limit of crankshafts by locally restricted hammering in areas of high stress, such as grooves, the mouths of bores and cross-sectional transition zones, in which method pressure impulse machines or beating devices comprising heating tools are employed. The pressure impulse machines or beating devices only execute a relative displacement of the beating tool against the surface of the crankshaft segment to be processed when the compressive stress is introduced between the heating tool and said surface of the crankshaft segment to be processed. The invention also relates to a device for increasing the endurance limit of crankshafts.
