Abstract
In order to improve a device for the manufacture of a shaft assembly for a hydrodynamic bearing by pressing a shaft into a fit bore in a bearing disk, comprising a first pressing tool and a further pressing tool, in such a way that enables high accuracy to be achieved when the shaft is pressed into the bearing disk, with the lowest possible cost and effort in setting up the press, it is proposed that a shaft receiving portion which receives and guides the shaft aligned exactly to a central axis is associated with the first pressing tool, that a bearing disk receiving portion which receives and guides the bearing disk with a flat surface aligned exactly perpendicular to an axis is associated with the first pressing tool, and that for the pressfitting process, the first pressing tool acts on the shaft or the bearing disk by means of a first pressing element and a second pressing tool acts on the bearing disk or the shaft by means of a second pressing element.
