  • Patent number: 11512735
    Abstract: The invention relates to a method for post-processing a crankshaft (4), in particular in order to correct concentricity errors and/or for a length correction. Sectors (S1,S2,S3,S4,S5,S6) of the crankshaft (4) which produce and/or characterize concentricity errors are detected and/or a length deviation (?L1 ?L2, ?L3) from a target length (L1,L2, L3) is determined for at least one section of the crankshaft (4). An impact force (Fs) is then introduced into at least one defined transition radius (8) between connecting rod bearing journals (5) and crank webs (7) and/or between main bearing journals (6) and the crank webs (7) of the crankshaft (4) by means of at least one impact tool (16) in order to correct the concentricity errors and/or the length deviation (?L1 ?L2, ?L3).

  • Patent number: 11344980
    Abstract: The invention relates to a method for work-hardening a crankshaft (4) comprising connecting rod journals (5), main bearing journals (6) and crank webs (7), the connecting rod journals (5) and the main bearing journals (6) being provided with oil holes (31). According to the invention, at least one end (30) of one of the oil holes (31) and/or at least one cylindrical portion (38) of the oil holes (31) is/are work-hardened.

  • Patent number: 11203056
    Abstract: The invention relates to a device 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). The device comprises an impact device (1) in order to introduce an impact force (FS) into at least one transition radius (8), wherein the impact device (1) has multiple impact heads (21) which are paired with the same transition radius (8).

  • Patent number: 11161206
    Abstract: The invention relates to a method for the impact treatment of transition radii (8) of a crankshaft (4, 4?), in particular transition radii (8) between connecting rod bearing journals (5, 5?) and crank webs (7, 7?) and/or transition radii (8) between main bearing journals (6, 6?) and the crank webs (7, 7?) of the crankshaft (4, 4?). 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?).

  • Patent number: 11141819
    Abstract: 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).
