Definitions

  • the invention relates to a device for pressing out wheel flange hubs or flange spline hubs of motor vehicles or the like. From a shaft bearing which is fixedly arranged in a bearing receptacle which is provided with an annular groove-like recess at least on one side of the bearing face, consisting of spreading sectors, each of which adjoins One end is supported on a support member having a central threaded bore and each is provided at its ends of its outer lateral surfaces opposite the support member with radial anchoring projections which can be positively inserted into the recess in the bearing receptacle, the spreading sectors being screwed into the threaded bore of the support member by means of an intermediate cone and with Threaded spindle surfaces provided are expandable and in a central, continuous, at least partially provided with a nut thread axial bore of the expansion cone or the threaded spindle a pressure spindle is screwed in with a pressure piece, which has a key head at one end.
  • a trigger device for the drive pinion of electric motors which corresponds to the generic device.
  • the spreading sectors are formed by axial slots and are an integral part of an annular body which is centered on a flange ring.
  • This flange ring is adjustably screwed onto the external thread of a sleeve body provided with an expansion cone and with an internal thread and with a pressure spindle and serves as a support member for the expansion sectors.
  • This trigger device is only suitable for removing drive pinions with a very specific inner diameter. No other use is possible.
  • the pressure medium used to pull off the wheel flange hub from a double-row ball bearing of the bearing cylinder consists of a plurality of bolts which are screwed into axial threaded holes in the flange of the edge flange hub and face each other support 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 also already known (FR-PS 959 338), in which a plurality of clamping sectors are guided in an axially movable manner in a cylindrical sleeve concentrically to the sleeve axis, which are moved axially by means of an expansion cone which is inserted in a Internal thread of the outer sleeve is screwed in, can be clamped such that its ends opposite the expanding cone engage behind the ring to be removed in a hook-like manner or that inner annular 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.
  • diametrically opposed, radially adjustable support feet are arranged on a cross member with respect to a threaded spindle, which on the edge of a component on the For example, a ball bearing should be pulled out, can be placed (DE-PS 857 329).
  • the threaded spindle is provided at its lower end with a collet, the neck of which engages with the thread of the threaded spindle by means of an internal thread and the expansion limbs of which can be expanded by means of an expansion cone.
  • 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.
  • devices of this type are not suitable for pressing out wheel flange hubs or spline hubs from the shaft bearings of a bearing cylinder of motor vehicles.
  • 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 suitable for the purpose according to the invention.
  • This device has a support bell, which can be placed on the end face of the tube from which the ring or the ball bearing is to be pulled out.
  • 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 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 reliability, wheel flange hubs or flange splines of motor vehicles from their Push out 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 two spreading sectors consist of separate, shell-like, semi-cylindrical bodies, each of which has axially arranged axial pins on their end faces facing an annular disk-like support member, in that the support member has a plurality of axial bores each lying in pairs on the same radius with different distances from the central axis of the threaded bore is provided, in which the axial pins can be inserted pivotably, and that the pressure piece is plate-like.
  • the design according to the invention ensures the advantageous possibility that the device can be easily dismantled and assembled, and that the spreading sectors can be set in a very simple manner to different inside diameters of different bearing cylinders.
  • the particular advantage is that the device is simple in construction and, above all, easy to handle.
  • claims 2 and 3 ensures that the pressure piece automatically centers itself in the bore of the wheel flange hub or flange spline hub when the pressure forces become effective.
  • 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 these are set to the smallest possible expansion diameter. This extends the use 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 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 gesi against axial displacement by two locking rings 10 seated in ring grooves 8 and 9 chert.
  • 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 spreading sectors 13 and 14, which are diametrically or mirror-image opposite one another with respect to a common axis 12, a support member 15, a spreading cone 16 with a hollow threaded spindle 17, which is provided with a nut thread 18, 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 support member 15 with axial pins 22 and 23 arranged on the side, which can be inserted in axial bores 24 and 25, respectively, of the same pressure, which are arranged in pairs on the same radius 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 end 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 are set to the smallest possible diameter of a bearing bore 7 or an annular groove 8, the expansion cone 16 does not axially out of the expansion sectors when the expansion sectors 13, 14 are inserted into the annular groove 8 13, 14 protrudes.
  • 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 to form 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, into 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 rolling 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.
