  • Method for the roller-straightening of crankshafts
    Patent number: 9676017
    Abstract: The invention concerns a process for roll straightening crankshafts (8, 8?) using crankshaft deep rolling tools (1 to 7), in particular work rollers (18,19) which, while the crankshaft (8, 8?) is rotated about its axis of rotation (21), are pressed into the recesses (14 to 17) or radii that delimit the bearing pins (Hi, Pi) on either side with a roll straightening force (27, 30) that constantly fluctuates around the circumference of a bearing pin (H1 to H5, P1 to P4). Roll straightening is carried out by determining the individual vector (34) of the runout by size and direction (35) at each main bearing (Hi) of the crankshaft (8, 8?).
