Abstract: A deep rolling machine has a power unit (13) attached in a gate (31) such that the power unit (13) can be moved in the direction of force exertion (30). The power unit (13) is connected, with articulation, at one end (32), via a joint (33), to the end (11) of a shearing arm (3) of the deep rolling unit (15). The free end (34) of the gate (31) is fit with a back up roller (35) that is routed along a curved web (36), defined in a gap in the second end (11) of the shearing arm (3). In the closed position of the power unit (13), three joints (28, 29, 33) form a triangle (37). One of the joints (28) points to the rotating joint (5). The two shearing arms (3 and 4) of the deep rolling unit (15) are articulately connected to one another at the rotating joint (5). Also in the closed position, a crank lever (27) reaches a limit stop (39) at the end (12) of the shearing arm (4).

Abstract: A measuring instrument has a first section for rolling a wheelset under lateral guidance of the wheelset into a measurement section with an auxiliary rail for supporting the wheelset on the outer edges of its wheels and a third section for rolling out the wheelset into the railway track, with the first and third section of the measuring instrument also designed as track panels and for which the optical beam devices under the measurement section are intended. The first and third section of the measuring instrument are flexibly embedded in the ballast of the superstructure of the railway track, while at least one of the optical beam devices is mounted vibration-free on the formation of the railway track in a pre-determined position in relation to the measurement section of the measuring instrument with no contact to the other parts of the measuring instrument.

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: A mobile wheelset reprofiling device mounted on rollers which can be moved on a workshop track for reprofiling wheelsets is provided. The wheelsets are mounted in a bogie such that they can rotate. The reprofiling includes using a mobile wheelset lathe, which can be connected to a corresponding service container which is also mounted on rollers and can be moved on a workshop track. A device for supporting another wheelset which is currently not being machined is also provided. The mobile wheelset lathe, the service container and the device for supporting the wheelsets are attached to a common support frame which is mounted on rollers which can be moved in the workshop track.

Abstract: The present invention relates to an underfloor wheelset lathe for machining the profile of wheels (8, 9) of wheelsets for railway vehicles, in which the wheelsets are rotatably mounted in axle bearing housing outside the wheels (8, 9), with a machine bed (10), two supports mounted on the machine bed that can be moved in the X and Z-axis direction of the underfloor wheelset lathe and are provided for holding tools for the machining, entry track rails (5, 6) that can be removed during machining for positioning the wheels (8, 9) over the tools, clamping elements for gripping the axle bearing housings, roller pairs for each wheel (8, 9) for lifting, driving and lowering the wheelset before, during and after machining. The underfloor wheelset lathe is intended for installation in an inspection shaft (1) for rail vehicles. It has a machine bed (10) with a vertical height (11) that is less than the depth (2) of the inspection shaft (1).
