    Abstract: A method for completely machining at least unprocessed centric journals (10) and crankpin journals (11), and the respective flat shoulders (9, 10) thereof surrounding the journals, of flanged or cast blanks of a crankshaft first includes turning the flat shoulders (9) associated with the journals (10). Then, the centric journals (10) are roughly ground without the flat shoulders (9) thereof and the crankpin journals (11) are roughly ground together with the flat shoulders (12) thereof. After the journals (10, 11) have been roughly ground, an allowance remains that is smaller than an allowance required for common finish grinding of journals and flat shoulders. The rough grinding is followed by the finish grinding of the centric journals (10) and the crankpin journals (11) from the smaller allowance (23) remaining due to the rough grinding to the final dimension.

    Abstract: 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.

    Abstract: The invention relates to a method for deep rolling the passes or radii on the transitions between journal and cheeks or flanges of crankshafts by means of a deep rolling device (1) of a deep rolling machine, said deep rolling device having a lazy tongs-type design. The deep rolling device (1) has two tongs arms (2, 3) that are articulated to each other via a pivot joint (24). The corresponding outer ends (4, 5, 9, 10) of the tongs arms (2, 3) are provided with a deep rolling tool (6) or a force generator (11) for generating the deep rolling force. A measuring tape (18) and a sensor (19) which are provided on the pivot joint (24) are used to measure the impression depth of the deep rolling rollers (12) under the effect of the deep rolling force. A measuring device (22) mounted on the exterior (21) of a tongs arm (2) is used to measure the degree by which the tongs arm (2) bends under the effect of the deep rolling force.

    Abstract: The deep-rolling device (8) of a deep-rolling machine (1) for crankshafts (3) is made in scissor construction. Two swivellable scissor arms (9, 10) opposite each other each carry a deep-rolling roller head (13) or a backing roller head (14) respectively. The backing roller head (14) is fitted with two parallel-axis backing rollers, the rotational axes of which lie in a common plane. The backing roller head (14) also has an axial guide which is arranged in front of the backing rollers in swivel direction (35) for closing, the longitudinal axis of which guide stands perpendicular to the rotational axis of the crankshaft (3) and lies in a plane which forms an acute angle with the common plane of the rotational axes of the backing rollers, and the axial width of which is greater than the width of the backing roller head (14) and slightly smaller than the distance of adjacent oil collars of a main bearing journal or big end bearing journal.

    Abstract: An apparatus (5) for the deep rolling of recesses (4) and radii of crankshafts (1). The deep rolling is accomplished with the aid of deep-rolling rollers (8) which, during revolution of the crankshaft (1), penetrate into the recesses (4) or radii of the crankshaft (1) under application of a deep-rolling force and at an angle of approximately 35° and bring about a deformation in the crankshaft (1) itself. According to the invention, the depth of penetration of the deep-rolling rollers (8) in the crankshaft (1) is measured in the radial direction and the magnitude of the deep-rolling force is regulated as a function of the measured penetration depth in such a fashion that in the course of at least one revolution of the crankshaft (1) a plastic deformation corresponding to a predefined rolling depth is obtained at least at one of the two recesses (4) or radii of a relevant journal bearing (2) after the deep rolling.
