    Abstract: Method of laser hardening of a surface area of a workpiece, such as a surface of a journal of a crankshaft, comprising: generating a relative movement between the surface of the workpiece and a laser source to allow a laser spot to subsequently be projected onto different portions of said surface area, and during said relative movement, repetitively scanning the laser beam (2) so as to produce a two-dimensional equivalent effective laser spot (5) on said surface area. The energy distribution of the effective laser spot is adapted so that it is different in a more heat sensitive subarea, such as in an area adjacent to an oil lubrication opening, than in a less heat sensitive subarea, so as to prevent overheating of said more heat sensitive subarea.

    Abstract: A system for assembling a vehicle drive shaft is provided with the steps of installing yokes on respective ends of a drive shaft tube, each yoke having first and second bores therethrough for receiving respective distal ends of respective spider arrangements, and rolling the outer edges of the bores using carbide rollers to urge a portion of the material of the yoke to overlie radially the respectively associated distal end of the spider arrangement. Datums are defined on the yokes and the shaft tube for determining a spatial relationship between the yokes and shaft tube. The rolling of the bore of the yoke is performed while the spider, the bearing caps, and the retention elements are maintained in preload to achieve zero tolerance. Prior to roller forming the outer edge of the bore, the spider arrangement is supported on the true rotating center of the drive shaft tube.

    Abstract: Bei einem Verfahren zum Fügen einer Nockenwelle unter Verwendung einer Welle (10) und von mehreren, jeweils eine Durchgangsöffnung für die Welle aufweisenden Nocken (21-26), werden die Nocken in einem Magazin (40) dicht gepackt, bezüglich ihrer Durchgangsöffnung für die Welle koaxial sowie in einer bestimmten Drehstellung relativ zueinander ausgerichtet. Dann wird die Welle in das Nockenpaket eingeführt und darin durch Verschieben in ihrer Längsrichtung nacheinander relativ zu einzelnen Nocken ausgerichtet. Die Nocken werden dabei nacheinander auf der Welle fixiert. Indem Welle neben ihrer Längsverschiebung ggf. auch noch um einen bestimmten Winkelbetrag gedreht wird, kann die notwendige Verdrehung der Nocken gegeneinander auf einfache Weise erzeugt werden.
