The invention regards a deep rolling machine (2) for crankshafts (5) with several deep rolling units (3) in a scissor-type configuration that are attached to the deep rolling machine (2) in the direction of the axis of rotation (4) of the crankshaft (5) with respective lateral distances (6) one besides another in a way that they can swivel thanks to the fact that some deep rolling devices (3) are intended for the deep rolling of main bearing journals (14) and other deep rolling units (3) are intended for the deep rolling of the pin bearing journals of the crankshaft (5) and that the deep rolling units (3) carry at the outer ends of their two scissor-type arms respectively one deep roller head (11) and a supporting roller head (9) that, together, form a deep rolling tool (3) where the deep rolling tool (10) along the scissor-type arms has a distance from the fastening point of the deep rolling unit (3) to the deep rolling machine (2) that is long when compared to the ratio between the width (7) of the scissor-type arms and their length. At least one of the deep rolling units (3) intended for the deep rolling of the main bearing journals (14) or of the pin bearing journals features a device (8) that enters into contact with the crankshaft (5) when the deep rolling unit (3) is in its working position, and that stabilizes the deep rolling unit (3) in the direction of the axis of rotation (4) of the crankshaft (5). |
