Abstract
The invention concerns a process for roll straightening crankshafts (') using crankshaft deep rolling tools (to), in particular work rollers () which, while the crankshaft (′) is rotated about its axis of rotation (), are pressed into the recesses (to) or radii that delimit the bearing pins (Hi, Pi) on either side with a roll straightening force () that constantly fluctuates around the circumference of a bearing pin (Hto H, Pto P). Roll straightening is carried out by determining the individual vector () of the runout by size and direction () at each main bearing (Hi) of the crankshaft (′). The largest () or resulting vector () is determined from the individual vectors (), then the main bearing pins (Hi) and crankpins (Pi) of the crankshaft (′) are roll straightened with a roll straightening force () the size () and direction () of the largest () or resulting vector () of which is between 0 and a multiple of the largest () or resulting vector ().
