Definitions

  • the spacer tube is provided at both ends with an internal thread, into which the threaded end wall with the axial support bearing and on the other hand one of the interchangeable support rings can be screwed.
  • the end wall itself has, on the outside opposite the threaded shoulder, a recess which is concentric with the central through-bore for the threaded spindle and in which the axial support bearing is accommodated and fastened.
  • the pressure pieces provided in this known device essentially designed as cylindrical washers of different diameters, are each provided on one side only with a centering projection and on the opposite side with a cylindrical recess for centering reception of a cylindrical guide part of the threaded nut, which means that they each can only be placed on the threaded spindle in a certain position.
  • the spacer tube has because it is closed all around at both tube ends End faces has the disadvantage that it can not be used in such bearing housings of motor vehicle axles that have no flat bearing surface all around, but are provided with elevations.
  • the end wall although detachably connected or connectable to the spacer tube, can likewise only be used in one pulling direction.
  • the invention is therefore based on the object of making the generic device more universally applicable by redesigning individual parts.
  • the spacer tube has an end face interrupted by at least one wall cutout on one end face and is provided on the other end face with a centering cone and / or a centering rebate and in that the end wall is centered from both end faces into the by a centering approach Spacer tube can be used loosely.
  • the embodiment of the invention according to claim 2 has the advantage that instead of the support bearing provided for the mounting of the threaded spindle, for example, a hydraulic pressing device can be screwed into the end wall in order to be able to use the device where higher pressing forces or tensile forces are required are that can not be generated with the threaded spindle.
  • the bearing insert part designed according to claim 3 has the additional advantage that it can be screwed into the end wall from one side or the other and this can optionally be used in one or the other pulling or pushing direction as a supporting element.
  • the embodiment of the invention according to claim 5 is used for easy handling of the bearing insert when screwing in and out of the end wall
  • the embodiment of the invention according to claim 6 enables the spacer tube in connection with the adapter tube also in such axle bearing housings of motor vehicles, in particular for pulling out the axle bearings, in which the maximum width of the end support surface has a smaller diameter than the spacer tube.
  • the embodiment according to claim 7 not only achieves additional centering between the one end face of the spacer tube and a supporting part resting thereon, but it also ensures that the interrupted end face does not have any radially outward pressing forces on the contrary, it is exposed to inward pressure forces that increase their resistance to breakage.
  • the embodiment of the invention according to claim 8 also gives the possibility of using the end wall itself as a centering support element without the spacer tube.
  • a threaded nut designed according to claim 10 simplifies the handling of the device in certain applications, specifically where its flange disc can be placed centering directly from a correspondingly configured end face of an axle bearing housing.
  • the device shown in the drawing consists of a threaded spindle 1, a bearing insert 2, a circular disk-like end wall 3, a spacer tube 4, support rings 5 and 6, an adapter tube 7, several axial pressure pieces 8, 9, 10 and 11, and a threaded nut 12 and a flange disk 13 replacing them.
  • the threaded spindle 1 is provided at one end with an annular flange 14 and behind it with a key profile 15, which preferably has a hexagonal shape.
  • the threaded spindle has a cylindrical centering projection 16, which ends at an annular stop shoulder 17 of the ring flange 14.
  • the bearing insert part 2 has a threaded shoulder 18, the axial length of which corresponds approximately to the total thickness of the end wall 3 and which can be screwed into a central threaded bore 19 of the end wall 3 alternately from both sides.
  • a threaded centering head 20 adjoins the threaded extension 18, which is larger than the threaded extension facing side has a radial stop shoulder 21 and is provided on its outer surface with a cross knurl 22.
  • the centering head can be provided with two parallel key surfaces so that it can be unscrewed in the threaded bore 19 by means of a key in the event of a tight fit.
  • the bearing insert part is provided with a through hole 23 for the threaded spindle 1.
  • an annular web 24 located approximately in the axial center, it also has, in two cylindrical recesses 25, an axial support bearing 28 or 29 secured by means of an axial locking ring 26 or 27, which can alternately serve as an attachment to the annular flange 14 of the threaded spindle 1.
  • the threaded shoulder 18 and the threaded bore 19 are designed such that, instead of the bearing insert part 2, a hydraulic pressure unit can also be used in the threaded bore 19, with which greater axial forces can be generated than is possible with the threaded spindle 1.
  • the end wall 3 has a cylindrical centering projection 30 matched to the inner diameter of the spacer tube 4, to which is connected an annular flange 31 matched in its outer diameter to the outer diameter of the spacer tube 4, the annular surface 32 of which facing the centering boss undercut by an undercut angle ⁇ of approximately 5 ° is. While the end face 33 of the centering lug 30 is flat, the opposite end face 34 of the end wall 3 has two short centering lugs 35 and 36 which are turned on in steps, on which, for example, roller bearing shells to be pressed in can be centered.
  • the spacer tube which in the practical version has an outer diameter of approximately 99.5 mm and a wall thickness of approximately 7.5 mm, is completely cylindrical on the inside and outside and has an axial length of approximately 80 mm.
  • These cutouts 38, 39, 40 serve for the unimpeded reception of projections and elevations which are present in some types of vehicles on the wheel bearing housings on which the spacer tube 4 has to be attached for pulling out the wheel bearing.
  • the spacer tube 4 On the end face opposite the wall cutouts 38, 39 and 40, the spacer tube 4 is provided with a centering inner cone 41 and then with a centering fold 42, both of which are matched to appropriately designed end faces of different axle bearing housings of motor vehicles.
  • the purpose of this undercut is the same as for the ring surface 32.
  • the two support rings 5 and 6 serve the same purpose as in the known device, only with the difference that they have no threaded attachments, but rather can be placed loosely on the end of the spacer tube 4.
  • the adapter tube 7 is provided at one end with a cylindrical centering projection 46, the outer diameter of which Inner diameter of the spacer tube 4 is matched so that it can be easily accommodated by this with little radial play.
  • the lying on the opposite side of the annular surface 45 extension member 46 ' has a tapering towards the opposite end face 47, so that its end face outer diameter D is smaller than the outer diameter of the spacer tube 4.
  • This adapter tube is used as an extension of the spacer tube 4 everywhere there, where an axle bearing housing has an end-face ring support surface, the largest outside diameter of which is smaller than the outside diameter of the spacer tube 4 and therefore the spacer tube 4 itself cannot be centered there.
  • the pressure pieces 8, 9, 10 and 11, which are essentially designed as cylindrical ring disks of different diameters and each have one or two cylindrical centering shoulders 49 to 55 of different diameters and can optionally be placed on the threaded spindle 1, are in their form on different roller bearings 56 matched so that they can be centered in the manner shown in FIGS. 1 and 4.
  • the device is shown as it is used for pressing a rolling bearing 56 into the bearing housing 57 of a motor vehicle steering knuckle 58 using both the spacer tube 4 and a support ring 5 and the pressure piece 8.
  • the bearing insert 2 is completely screwed into the threaded bore 19 of the end wall 3, that the threaded spindle 1 is inserted through the bearing insert 2 and the spacer tube 4, the support ring 5, the bearing housing 57, the roller bearing 56, and that Thrust piece 8 extends through and that the threaded nut 12 is screwed onto the end of the threaded spindle 1 protruding from the pressure piece 8.
  • the end wall 3 is also centered in the spacer tube 4 as with one of its inner support shoulders on the end face 57 'of the bearing housing 57 centered support ring 5.
  • the simultaneous centering of the pressure piece 8 in the roller bearing 56 ensures that when tightening the threaded spindle 1 under simultaneous retention of the threaded nut 12 on the bearing housing 57 and the roller bearing 56 do not allow tilting of the roller bearing, but rather guarantee a faultless insertion of the roller bearing into the bearing housing 57.
  • the flange disk 13 In the application example of FIG. 5, only the threaded spindle 1, the end wall 3 with the inserted bearing insert 2 and, instead of the threaded nut 12, the flange disk 13 are used by the device according to the invention for pressing a rolling bearing 56 into another bearing housing 62.
  • This flange disk 13 has a central threaded bore 63 which fits onto the threaded spindle 1 and a cylindrical hub shoulder 64.
  • the flange disk is provided in the vicinity of the circumference with an annular groove 65 which is approximately semicircular in cross section and which is also surrounded by a semicircular annular rib 66 is.
  • the cross-sectional profile of the annular groove 65 and the annular rib 66 are, as shown in Fig. 5, adapted to a corresponding counter profile 67 on the end face 68 of the bearing housing 62, so that the flange disc 13 can be centered there in the manner shown to the rolling bearing 56 in the direction of arrow 69 in the bearing housing 62.
  • the end wall 3, the spacer tube 4 and the pressure piece 11 as well as the threaded nut 12 are required by the device, as shown in FIG. 4, in addition to the threaded spindle 1.
  • the spacer tube 4 is placed on the annular end face 70 of the bearing housing 62.
  • This end face 70 is provided with a conical facet 71 which is exact fits into the inner cone 41 of the spacer tube 4 so that it is centered on this facet 71.
  • centering projection 51 of the pressure piece 11 protrudes centering into the bore of the roller bearing 56, so that when the threaded spindle 1 is rotated in the pulling direction, the forces acting on the roller bearing 56 and the bearing housing 62 run exactly axially and do not permit tilting.
  • FIGS. 1, 4 and 5 show that, depending on the application, different parts of the overall device are used.
  • the inventive design of the individual components of the device ensures that these are sufficient in minimal number for almost all applications when pressing in and pulling off axle bearings.
