  • the axial pressure surface with which the axial pressure on z. B. the roller bearing to be pulled or pressed in is therefore located on a different part than the centering approach, the sole purpose of which is to center the pulling or pressing tool in the radial direction. This takes into account the fact that the inner diameters of the components to be drawn or pressed in on the one hand and the front diameters of these components on the other hand are often subject to different standard systems in practice.
  • a cylindrical seat is first formed on the centering sleeve, which surrounds the threaded spindle, axially one after the other, which serves to accommodate the thrust washer, and a centering projection formed directly on the centering sleeve, which, when the tool is used, is inserted into the inner bore, for. B. the rolling bearing to be pulled engages with little radial play and this centers the tool.
  • the centering sleeve also on the one hand and the threaded nut on the other hand are separate components, and that the Centering sleeve with a smooth through hole on the thread of the Threaded spindle is guided.
  • a division of tasks is hereby achieved in which the centering sleeve the seat of the thrust washer and the centering of the Tool is used, whereas the generation of the axial pressure by means of Threaded nut is made with an internal thread on the external thread the threaded spindle is seated.
  • the centering sleeve is preferably of identical design at both ends Provide shoulders for receiving one end of the nut. To this way, the centering sleeve can be used by both her and her push the other side onto the threaded spindle.
  • the Both ends of the centering sleeve can be designed differently, so either Centering approaches to form different diameters, or different to provide large cylindrical seats to accommodate thrust washers. in the Everybody therefore offers the sense of universal applicability of the tool Centering sleeve two different dimensions. Despite this variability, make the centering sleeve compact, if according to a further embodiment the paragraphs which are used to hold the respective end of the threaded nut are provided, are arranged within the centering lugs.
  • the centering sleeve with a radially expanded support collar is provided, on which the thrust washer axially supported.
  • This support collar allows a uniform over the circumference and tilt-free transmission of the axial pressure from the centering sleeve to the Pressure washer.

  • the roller bearing 1 is composed of an outer ring 1a, two inner rings 1b and the rolling elements 1c together.
  • the rolling bearing 1 sits in a bearing housing 3, which is part of the wheel suspension Motor vehicle is.
  • the installed rolling bearing 1 is via circlips 4a, 4b axially secured within the bearing housing 3.
  • the tool according to the invention has a basic component continuous threaded spindle 5, at one end with a flats provided hexagon 6 is integrally formed. Below the hexagon 6 is also integrally formed a stop shoulder 7, which at Embodiment supported on the outer ring of a thrust bearing 8. The inner ring of the Axial bearing 8 in turn is supported on the outside 9a of an end wall 9 which Is part of a bell-shaped support element 10.
  • the Support element 10 consists of a provided with openings 11 cylindrical part 12, as well as the end wall 9 formed thereon, whereby overall the shape of a bell results, with its open face can support the bearing housing 3.
  • the hexagon 6 with the stop shoulder 7 opposite end is a threaded nut 13 on the threaded spindle 5 screwed.
  • an internal thread 14 of the threaded nut 13 engages in the External thread 15 of the threaded spindle 5.
  • the threaded nut 13 is with a preferably integrally formed thereon hexagon 16. To this It is possible by a relative actuation of the two hexagons 6, 16 to move the threaded nut 13 axially along the threaded spindle 5 and on this way to pull or press the rolling bearing 1 or Apply the required axial pressure to the wheel flange hub 2.
  • FIG. 1 shows that the internal thread 14 of the Threaded nut 13 extends only over part of the total length, wherein this threaded section with respect to the center of the total length of the Threaded nut 13 is arranged asymmetrically.
