Definitions

  • the invention relates to a clamping device for removing bearing rings from wheel flange hubs with two clamping jaws which can be moved relative to one another by threaded engagements and which are each provided with recesses opposite one another in a common plane.
  • Devices of this type are required and used to pull off inner rings of ball bearings pressed onto wheel flange hubs of motor vehicles.
  • the two clamping jaws consisting of essentially semicircular disks are parallel by two in a diametrical tangential position mutually extending arrangement on the clamping jaws threaded spindles can be pressed against each other.
  • the two jaws are each provided on the side facing each other with semicircular recesses, which can be more or less appropriately attached and braced on the end face of the collar of the bearing ring to be removed if a corresponding ring groove is present.
  • an additional drawing tool which has two threaded bolts attached to a beam, which can be screwed into the threaded bores of the two clamping jaws, a pressure spindle being arranged in the middle of the beam, with which the flange hub can be axially fixed with the help of a pressure piece Direction can be pushed out of the bearing ring.
  • the invention is based on the object of improving a device of the type mentioned in such a way that it is univer sell usable, easy to handle, attachable to different bearing rings of wheel flange hubs and, if necessary, can be used or used both with a mechanical pulling device having a pressure spindle and on pneumatic, hydraulic or mechanical presses.
  • the two clamping jaws each consist of equally thick, flat, plate-shaped bodies and are arranged in a form-fitting manner in a flat, flat clamping frame consisting of two parallel longitudinal legs and at least one cross leg connecting them such that at least one clamping jaw is movable along the longitudinal limbs and the middle of a threaded spindle seated in a threaded bore of the transverse limb can be pressed against the other by a stop or by screwing to the longitudinal limbs immovable clamping jaw.
  • the device is not only easy to handle and space-saving, but it also has the advantage that the attachment of the clamping jaws on the bearing ring to be removed can be seen and controlled as easily as the removal process itself.
  • Another important advantage of the this design is achieved consists in the fact that the entire device with a clamped bearing ring still seated on the bearing hub of a wheel flange hub can easily be placed on the work table of a pneumatic, hydraulic or mechanical press to push the wheel flange hub downwards.
  • the possibility is given to press out wheel flange hubs with a diameter of 12 cm and more on the press table of a press from the clamped bearing ring, in which the spacer blocks outside the diameter of the wheel flange can be placed as a support under the device .
  • the configuration of the innovation according to claim 4 is provided, the configurations according to claims 5, 6 and 7 serving, on the one hand, to simplify handling and, on the other hand, to increase functional reliability and vigorous resilience.
  • the device can also be used in combination with already known drawing devices or with a drawing device designed as a pull bell or pull bridge.
  • the clamping device 1 for removing bearing rings 2 from wheel flange hubs 3 consists of two clamping jaws 4 and 5, which are arranged between two parallel legs 6 and 7, which are connected at one end by a cross leg 8.
  • the longitudinal legs On their mutually facing inner sides, the longitudinal legs each have spring-like guide ribs 9 and 10, which positively engage in correspondingly profiled lateral longitudinal grooves 11 or 12 or 13 and 14 of the two clamping jaws 4 and 5.
  • the cross leg 8 is provided on both sides with grooves 8 ', in which the guide ribs 9 and 10 of the two longitudinal legs 6, 7 engage in a form-fitting manner, and contribute to the stiffening of the stenter.
  • the clamping jaw 5 is on the guide ribs 9 and 10 between the clamping jaw 4 on the one hand and the cross leg 8, which is also at the other end the two longitudinal legs 6 and 7 is screwed by screws 16, about 30 mm in the longitudinal direction back and forth.
  • the two clamping jaws 5 and 6 each consist of flat, plate-like bodies of the same thickness and that both the longitudinal legs 6 and 7 and the transverse leg 8 have the same thickness as the clamping plates 4 and 5, so that their flat surfaces are each in a common plane.
  • the two jaws 4 and 5 are each provided with semicircular recesses 17 and 18, each of which has a semicircular, rectangular or square in cross-section, spring-like edge rib 19 or 20, which for the positive reception different on the Outer shape of different bearing rings matched clamping shells 21 and 22 and 23 serve.
  • the longitudinal displacement of the clamping jaw 5 takes place by rotating a threaded spindle 24, which is seated in a threaded bore 25 of the transverse leg 8 and the front end of which is rotatably fastened by means of an O-ring 26 in an end blind bore 27 of the clamping jaw 5.
  • a toggle 28 at its free end.
  • the two formed as a semicircular body clamping shells 21 and 22 and also the clamping shells 23 and 23 ⁇ of Fig. 2 are provided on their circumference with an annular groove 29 which is shaped in profile so that it one of the edge ribs 19 or 20 of the two clamping jaws 4 or 5 can be positively but with a certain radial play, which enables exact centering on the bearing ring 2.
  • the two clamping shells 21 and 22 are each provided on their inside with a semicircular profile, inwardly projecting ring rib 30, the clamping shells 23 and 23 ⁇ have an inwardly projecting gripper nose 31 on their lower edges, which in corresponding recesses 32 (Fig.
  • a wheel flange hub 3 can engage behind the front of the bearing ring 2 to be removed, as shown in FIG. 2.
  • bearing rings 2 which have a ball groove 2 ⁇ on their circumference
  • clamping shells 21 and 22 are firmly clamped in the clamping device 1, which have correspondingly profiled ring ribs 30 on their inner sides, as shown in FIG. 3.
  • a pull-off bell 33 can be used, as shown in FIG.
  • the wheel flange hub 3 can be pressed out of the bearing ring 2 by means of a pressure spindle 41, which is rotatably seated in a central threaded bore 43 of the neck of the pull-off bell by means of a toggle 42, by means of a pressure piece 45 placed on the end face of the hollow hub 44. It is expedient to clamp the clamping device 1, for example in a vice, in order to be able to apply the necessary torque more easily to the threaded spindle 41.
  • annular flange 34 is provided with elongated holes 36 and 37 for pushing through the screws 38 so that centering of the pull-off bell 33 to the clamped-in wheel flange hub 2 is possible.
  • a pull-off bell or similar pull-off device for example a pull-off bridge
  • the clamping device 1 with the help of two spacer blocks 50 and 51 on the press table 52 one not further to set the press of any design and function and to push the hollow hub 44 out of the bearing ring 2 with the press ram 53 using a suitable pressure piece 54. It is understood that one can perform the pull-off process more easily with a hydraulically or pneumatically operated or with an eccentric press, which is able to apply several tons of pressure, than with a pull-off bell 33 or a similar pull-off device.
  • the clamping device 1 is designed such that the surfaces of both the clamping jaws 4 and 5 as well as the longitudinal legs 6 and 7 forming a clamping frame each form smooth planes.
  • at least the length or the width of the tensioning device 1 is chosen so large that it projects beyond the largest possible diameter of a wheel flange hub 3 by at least 4 cm, so that the two required spacer blocks 50 and 51 can be placed outside the wheel flange hub.
  • FIGS. 2 and 3 It can be seen from FIGS. 2 and 3 that the pulling-off process can be easily observed from above in one case as in the other.
  • clamping shells 21, 22 and 23, 23 ⁇ are available so that the clamping device 1 can be used universally. Due to the solid and flat design, the frame-like construction has a very high strength, so that high compressive forces can be absorbed or applied both in the clamping direction and in the pulling direction, with the possibility at any time, by appropriate rotation of the threaded spindle 24, the compressive stress with which the bearing rings to be removed are clamped in the device to increase.
