Device for pressing in and pulling off bearings or sleeves, in particular for axle bearings and/or wheel flange hubs on motor vehicles

摘要

A device for placing i.e., pressing in and pulling off, bearings or sleeves, in particular for axle bearings and/or wheel flange hubs of motor vehicles, includes a threaded spindle with an abutment shoulder and threaded nut, a cylindrical spacer tube with a loosely insertable front wall receiving a thrust step bearing. The device includes several axial pressure pieces which can be arranged exchangeably on the threaded spindle between the threaded nut and a workpiece. To achieve universal usability, the spacer tube is provided on one side with an end ring surface interrupted by at least one wall cutout and on the other side with a centering cone or a centering rabbet. The front wall is insertable into the spacer tube through a centering projection selectively from both end faces. In addition, the thrust step bearing is accommodated in a bearing insertion part which can be screwed into a central threaded bore of the front wall and can be replaced with the threaded spindle e.g. by a hydraulic pressing device.
