Definitions

  • the invention relates to a device for pressing out wheel flange hubs or flange splined hubs of motor vehicles or the like from a shaft bearing, which is fixedly arranged in a bearing cylinder, which is provided at least on one end face of the bearing with an annular groove for receiving a retaining ring, consisting of itself on the bearing cylinder supportive pressure media actuable by screw thread.
  • the pressure medium used to pull off the wheel flange hub from a double-row ball bearing of the bearing cylinder are made of several bolts that are screwed into axial threaded holes in the flange of the wheel flange hub and are supported on the end face on a radial surface of the bearing cylinder. Since it is not possible to turn all the bolts evenly at the same time, it is also not possible to prevent the wheel flange hub from tilting with these means. These means are therefore extremely inadequate for the professional removal of the wheel flange hub from its ball bearings.
  • FR-PS 959 338 Devices for pressing out shaft ends from pressed-on bearing rings or the like are already known (FR-PS 959 338), in which a plurality of clamping sectors are guided axially and radially movably in a cylindrical sleeve concentrically to the sleeve axis, which are moved by means of an expansion cone which is in an internal thread of the outer sleeve is screwed in, can be clamped in such a way that its ends opposite the expanding cone engage behind the ring to be removed in a hook-like manner or that inner ring beads of the clamping sectors engage in an annular groove of a bearing ring.
  • the end of the sleeve opposite the internal thread is provided with an inner cone on which the clamping sectors are supported in order to be moved radially inward when axially displaced.
  • the expansion cone itself is also provided with a coaxial threaded hole into which a pressure spindle is screwed, with which the axial pressure required for pressing out can be exerted on the end face of the shaft end.
  • the expansion cone has a long shaft which projects through the hollow body and which is provided at its upper end with a thread protruding from the upper end of the threaded spindle and clamped in the axial direction by means of a nut which is seated on the upper end face of the hollow threaded spindle can be.
  • the threaded spindle itself is also provided with a clamping nut, which is supported on a ring bearing of the cross member.
  • the expansion sleeve can be moved axially relative to the drawing tube, so that the expansion fingers can be expanded.
  • a threaded pressure spindle which is provided with a key head at its end protruding from the threaded bolt and with a pressure piece at the opposite end, which can be placed on the end face of a shaft enclosed by the ring seal .
  • This device is also not for suitable the purpose of the invention. The same also applies to another known pulling device, which is used to pull pressed rings or ball bearings out of hollow shafts, pipes or the like (US Pat. No. 2,031,938).
  • This device has a support bell, which can be placed on the face of the tube from which the ring or the ball bearing is to be pulled out.
  • a freely rotatable threaded spindle In this support bell is a freely rotatable threaded spindle, the lower end of which is provided with an expansion cone and the upper end, which protrudes from the support bell, is provided with a toggle nut which is seated on a counterpressure surface of the support bell.
  • On the expanding cone are two diametrically opposed arranged spreading fingers, which are provided with radially outwardly projecting hook-like gripping elements which can reach behind the ring to be pulled out. These spreading fingers are provided with radial angle pieces which have bores through which the threaded spindle protrudes. Threaded nuts are arranged above and below these two angle pieces, with the help of which the axial position of these spreading fingers can be fixed on the threaded spindle.
  • the invention has for its object to provide a simple, space-saving and adjustable to different diameters of bearing cylinders device of the type mentioned, with which it is possible in a simple manner and with the necessary operational safety, wheel flange hubs or flange splined hubs from motor vehicles their shaft bearings in which they are stuck, thereby ensuring that the compressive forces required for pressing out act in exactly the coaxial direction and that damage to the hub is avoided with certainty.
  • the configuration according to claim 2 ensures the advantageous possibility that the device can be easily dismantled and assembled, and that the spreading sectors can be adjusted in a very simple manner to different inner diameters of different bearing cylinders.
  • the design of claims 3 and 4 ensures that the pressure piece automatically when the Centered compressive forces in the bore of the wheel flange hub or flange spline hub to be released.
  • the embodiments of the invention according to claims 5 and 6 ensure that the device can also be used with the movable pressure piece in those cases in which the annular groove of the bearing cylinder is located directly on the end face of the shaft bearing. Furthermore, it is ensured by the features of claim 6 that the expansion cone is still in the axial direction within the two expansion sectors and is not a hindrance when the expansion sectors are set in an annular groove if this is set to the smallest possible expansion diameter. This extends the application possibilities of the same device in that it can be easily adjusted to different inside diameters of bearing cylinders.
  • the bearing cylinder 1 of a motor vehicle steering knuckle 2 with a wheel flange hub 3 is also shown.
  • the wheel flange hub 3 has a cylindrical, hollow spline hub 4 which is pressed firmly into a roller bearing 5 serving as a wheel bearing and is to be pressed out with the aid of the device according to the invention in the direction of arrow 6 from this roller bearing 5, which at least initially remains in the bearing cylinder 1.
  • the roller bearing 5 is pressed into the cylindrical bore 7 of the bearing cylinder 1 and secured against axial displacement by two retaining rings 10 seated in ring grooves 8 and 9.
  • the pressure tool 11 which serves to press the wheel flange hub out of the roller bearing 5
  • the securing ring 10 has already been removed from the annular groove 8 and is therefore not visible in FIGS. 1 and 2.
  • the pressure tool 11 consists of two with respect to a common axis 12 diametrically or mirror image opposite, consisting of semi-cylindrical shell bodies consisting of spreading sectors 13 and 14, a support member 15, an expanding cone 16 with a hollow threaded spindle 17 with a nut thread 18 is provided, and a pressure spindle 19 and a pressure piece 20 which is arranged elastically on a cylindrical end projection 21 of the pressure spindle 19.
  • the nut thread does not have to extend over the entire length of the threaded spindle 17.
  • the two spreading sectors 13 and 14, which are of identical design, are each provided on their end faces facing the supporting member 15 with axial pins 22 and 23, respectively, which are arranged in pairs and have axial bores 24 and 25, respectively, of the same radius, of the pressure piece 15 designed as a cylindrical disk are.
  • the diameter of the axial bores 24 and 25 are larger than the diameter of the axial pins 22 and 23, so that the expansion sectors 13 and 14, when the axial pins 22 and 23 are inserted in the axial bores 24 and 25, can also be pivoted in the radial direction. As can be seen from FIGS.
  • the pressure piece has a total of three pairs of such axial bores, namely still the additional pairs of axial bores 26 and 27 or 28 and 29, which are each arranged symmetrically to the central axis or to the center of the disk-shaped support member 15 and whose distances R1 or R2 and R3 are of different sizes or are arranged in pairs on differently sized radii R1 / 2, R2 / 2 or R3 / 2.
  • R1 or R2 and R3 are of different sizes or are arranged in pairs on differently sized radii R1 / 2, R2 / 2 or R3 / 2.
  • the two expansion sectors 13, 14 have, on the end sections facing away from the support member 15, enlarged inner recesses 33 into which the expansion cone 16 can be freely inserted, while the remaining sections of the two Spreading sectors each have semicircular recesses 34 of smaller diameter, which each form spreading edges 35 at the transition to the larger recesses 33, which can be conical or rounded and against which the spreading cone 16 lies with its conical outer surface. It can be seen from FIG. 2 that the spreading edges 35 are at a certain axial distance from the drinking edges 13 'and 14' of the spreading sectors 13 and 14, respectively.
  • This distance is chosen so that when the two expansion sectors 13 and 14 to the smallest possible diameter of a bearing bore 7 or an annular groove 8 are set, the expansion cone 16 does not protrude axially from the expansion sectors 13, 14 when the expansion sectors 13, 14 are inserted into the annular groove 8.
  • the minimum distance must at least correspond to the expansion stroke of the expansion cone 16.
  • the two expansion sectors 13 and 14 have radially outwardly projecting, rib-like anchoring projections 36 and 37 which, as can be seen from FIG. 2, can be inserted in a form-fitting manner in the annular groove 8 of the bearing cylinder 1.
  • the expansion cone 16 is moved with the aid of the threaded spindle 17 relative to the two expansion sectors 13 and 14 in the direction of the arrow 38, so that the two expansion sectors 13 and 14 are axially anchored in the annular groove 8 results. Thereafter, it is only necessary to turn the pressure spindle 19 by attaching a rotary key to the hexagon key head 32 so that an axial movement occurs in the direction of arrow 6, through which the pressure piece 20, which is located on the bore of the spline hub 4 provided with splines 4 ′ can center itself, pushes the wheel flange hub 3 out of the roller bearing 5, which is still secured against axial displacement by the locking ring 10.
  • a helical spring 39 is provided, which is joined into a ring and is guided in outer annular grooves 40 of the two expansion sectors 13 and 14.
  • the annular groove 8 of the bearing cylinder 1, in which the rib-like anchoring projections 36 and 37 of the two expansion sectors 13 and 14 are anchored, is in the immediate vicinity of the end face of the roller bearing 5 or the spline hub 4, it is necessary for the pressure piece 20 within the axial length of the two expansion sectors 13 and 14 to provide a space in which the pressure piece 20 can be sunk in the axial direction when the two expansion sectors 13 and 14 are fastened in the annular groove 8.
  • the two recesses 33 are sufficient to be able to insert the pressure piece 20 axially deep enough into the two ring sectors 13 and 14.
