摘要： The invention relates to a method for measuring and calculating geometric parameters of the wheels of a wheelset for rail vehicles, wherein the wheelset to be evaluated is rotatably mounted in a wheelset machine tool or in a wheelset diagnostic system and wherein measured values for profile measurement with respect to profile wear to be detected are determined during rotational motion of said wheelset. The problem addressed by the invention is to expand already available measuring methods on known wheelset machine tools and wheelset diagnostic systems in such a way that further geometric parameters can be detected and evaluated. This problem is solved in that methods for measuring and calculating the equivalent conicity and the radial run-out property of a wheelset are integrated as new measurement functions, wherein solution approaches are proposed for these additional methods.

摘要： The invention concerns a rolling unit for machining the wheel running surfaces of wheelsets for rail vehicles, with the rolling unit featuring at least one work roller by means of which the wheel running surface to be machined is subjected to a deep rolling process following manufacture of the wheelset in new condition or, at a later date, after reprofiling to increase the service life of the wheel running surfaces. The task is solved to create a relevant rolling unit by means of which the wheel running surfaces can be deep-rolled in the forward feed process using work rollers. This task is solved by the rolling unit featuring a base body on which a support arm is located in a vertical position to the base area, on which a receptacle is supported that is unilaterally fixed in position via a thread in the support arm and on which an angular contact ball bearing is located; this supports at least one work roller featuring at least two different rolling radii.

摘要： A method and compression roller tool for increasing the strength of load-bearing surfaces on shafts, in particular on crankshafts, which surfaces are pre-machined with the removal of chips, wherein the cylindrical surfaces of the main bearing journals and pin-bearing journals and optionally also the journal of crankshafts have additional oil bores. At least one of the load-bearing surfaces is compression-rolled by way of at least one cylindrical body which has a surface structure and extends over the width of the load-bearing surface. Afterwards, the compression-rolled load-bearing surfaces are machined with the removal of chips with a low chip depth. The compression roller tool consists of a cylindrical compression roller body and a supporting body opposite it, wherein the compression roller body has thickened portions on its cylindrical surface, which thickened portions run either in the circumferential direction or in the axial direction or diagonally with respect to the axial direction.

摘要： The disclosure relates to a method for radially aligning wheelsets of rail vehicles relative to a coordinate system of a wheelset diagnosis tool and/or wheelset machine tool, which method can be implemented quickly with sufficient precision and comprises the following steps: a) positioning the wheelset at a working position of the tool; b) defining a tool-side coordinate system in an assumed wheel centre point of each wheel, where an X-axis adopts a vertical extent, a Y-axis adopts a horizontal extent and a Z-axis describes the resulting depth extent of the wheel; c) measuring the distance of the wheel backs with respect to one another and defining the Z-position=0 on each wheel back; d) defining a unique Z-position for each measuring point; e) positioning each measuring sensor at the specified Z-position; f) measuring the X-position of each measuring point; g) aligning the wheelset by vertically displacing one of the wheels in order to match the X-positions of the measuring points of two wheels.

摘要： A rolling tool for the roller finishing of bearing surfaces of a crankshaft is pivotable around a crankshaft axis, with a finishing roller head and with a support roller head. In order to prevent damage to the guide mechanisms, the roller finishing roller is guided on all sides in a roller cage and the finishing roller head has a frame wherein it is mounted pivotably around a first pivot axis which is perpendicular to the crankshaft axis and parallel to a tangent on a working side of the roller finishing roller. Additionally or alternatively, the support roller head comprises a support roller frame in which the support roller housing is mounted pivotably around a second pivot axis perpendicular to the crankshaft axis and parallel to the first pivot axis, and around a third pivot axis perpendicular to the crankshaft axis and perpendicular to the first pivot axis.
