Abstract

Beschrieben wird eine Wellenricht- und -härtemaschine, mit einer Aufnahme für ein wellenförmiges Werkstück, in welcher das Werkstück um seine Längsachse drehbar gehalten ist, mit einem Drehantrieb und einem Kühlmittel für das Werkstück, sowie mit wenigstens einer an einer vorgegebenen Richtstelle der Werkstücklänge angeordneten Richteinrichtung, welche eine gegen das Werkstück zustellbare Richtrolle sowie ein Paar von auf Wellen gelagerten Gegenrollen aufweist, wobei die Wellen um eine zur Werkstücklängsachse parallele Achse drehbar sind. Zur Vereinfachung der Zustellung der Gegenrollen beim Einrichten des Werkstückes ist vorgesehen, dass jede Gegenrolle des Paares auf das freie Ende ihrer Welle drehfest, jedoch austauschbar aufgesteckt ist, und durch die vorgegebene radiale Abmessung des Werkstückes an der Richtstelle der Durchmesser der Gegenrolle des Paares bestimmt ist.

Figure 00000001
A shaft straightening and hardening machine is described, with a receptacle for a wavy workpiece, in which the workpiece is held rotatably about its longitudinal axis, with a rotary drive and a coolant for the workpiece, and with at least one straightening device arranged at a predetermined straightening point of the workpiece length which has a straightening roller that can be set against the workpiece and a pair of counter rollers mounted on shafts, the shafts being rotatable about an axis parallel to the longitudinal axis of the workpiece. To simplify the infeed of the counter rollers when setting up the workpiece, it is provided that each counter roller of the pair is non-rotatably but interchangeably attached to the free end of its shaft, and the diameter of the counter roller of the pair is determined by the predetermined radial dimension of the workpiece at the point of alignment ,
