Definitions

  • the invention relates to a pulling device for pulling a rolling bearing from a shaft, according to the preamble of claim 1, as is known from DE-A-819830.
  • the cone of the clamping sleeve slides on the conical outer surface, which is formed by the spring tongues, in accordance with the rotation and displacement movement of the clamping sleeve.
  • strong frictional forces act on the conical contact surfaces, so that for the rotational movement of the clamping sleeve requires large forces that can only be applied using auxiliary tools such as hook or fork wrenches.
  • the wear on the conical contact surfaces is high.
  • the clamping sleeve is divided into a pressure sleeve and an adjusting sleeve, but these two sleeves lie directly against one another with their facing end faces, so that considerable frictional forces have to be overcome in order to twist the adjusting sleeve .
  • the pressure sleeve can also be rotated unintentionally. In addition, it is not possible to reset the pressure sleeve by means of the adjusting sleeve.
  • the invention has for its object to simplify the handling of the puller.
  • the object is achieved according to the invention with the characterizing features of claim 1.
  • the inventive two-part design of the adapter sleeve with the connection via driver and bearing makes it possible to transmit only the axial forces to the spring tongues of the withdrawal sleeve, since only the adjusting sleeve forming part of the adapter sleeve is rotated on the hollow body and thereby relative to the other Part of the clamping sleeve forming the pressure sleeve rotates, but axially entrains this pressure sleeve. In this case, only a sliding movement in the axial direction arises between the conical contact surfaces, and the friction is considerably reduced in comparison to the known pulling devices, so that considerably lower actuating forces are accordingly required.
  • the device has a hollow body 1 through which a threaded spindle 2 passes.
  • the hollow body consists of a withdrawal sleeve 3, a shaft 4 screwed into this sleeve and a threaded insert 5 screwed into the shaft, which has an internal thread 6 for the spindle 2 provided with an external thread 7.
  • the division of the hollow body 1 into the withdrawal sleeve 3 and the shaft 4 makes it possible to use withdrawal sleeves of different types while maintaining the remaining parts of the device, as is described in detail in the aforementioned DE-AS 1 269 069.
  • the puller can also be extended if necessary by inserting a further shaft corresponding to the shaft 4, since the threaded insert 5 can also be unscrewed and a correspondingly longer threaded spindle 2 is to be used.
  • the withdrawal sleeve 3 is axially slotted up to close to its threaded end, so that separate tongues 9 are formed by slots 8, which are designed to be radial to the longitudinal axis A of the withdrawal device.
  • These spring tongues have outwardly flared ends 10 which form a conical outer surface 11 of the withdrawal sleeve 3.
  • the free ends of the conical ends 10 form pull-off elements 12, which in the exemplary embodiment are designed as grippers, but can also be claws, as are shown in DE-AS 1 269 069.
  • the pulling grippers 12 grip over the rollers of a tapered roller bearing to be removed and thereby grasp this bearing, for which purpose the spindle 2 is supported with its inner end on the end face of the shaft on which the bearing is seated.
  • an adapter sleeve 13 is provided, which essentially consists of a pressure sleeve 14 and an adjusting sleeve 15.
  • the pressure sleeve 14 ends in an inner cone 16, which has the same apex angle as the conical lateral surface 11 and accordingly rests with its inner lateral surface 17 on the surface 11 without play.
  • the pressure sleeve 14 is axially displaced by means of the adjusting sleeve 15.
  • the adjusting sleeve 15 with its internal thread 18 can be rotated on an external thread 19 of the shaft 4 and is thereby axially adjustable.
  • a driver designed as an annular disk 20 is provided, which is arranged with a press fit in the adjusting sleeve 15 and bears against a shoulder 21 of this sleeve, that is to say can be rotated with the adjusting sleeve.
  • One of two axial needle bearings 22 and 23 is located on either side of the annular disk 20.
  • the outer ring 24 of the bearing 22 is supported on a shoulder 25 of the pressure sleeve 14.
  • the outer ring 26 of the bearing 23 lies against a snap ring 27 which is inserted into the pressure sleeve 14 and which forms a fixed driver and does not touch the adjusting sleeve.
  • Another driver also designed as a snap ring 28, is inserted into the adjusting sleeve 15 near one end thereof.
  • a pot ring 29 which serves as a dust seal for the double bearing 22, 23 and with the outer ring 24 of the bearing 22 and with the outer surface of the pressure sleeve 14 forms a gap of very small width, so that it with them Sharing is not in touch.
  • a guide pin 30 is inserted into the pressure sleeve 14, which is slidably guided in an axial guide slot 31 of the shaft 4.
  • an annular gap of small width is an annular gap of small width, so that there is no surface contact.
  • the axial thrust force is transmitted via the driver 28, the pot ring 29, the driver 20, the bearing ring 26 and the driver 27 to the pressure sleeve 14, which is axially guided in the same way.
  • the adjusting sleeve 15 can be rotated by hand, which is facilitated by an external corrugation 32A.
  • two recesses 32 and 33 are provided in the adjusting sleeve 15, into which an adjusting tool, for example an open-ended wrench, can engage.
  • Two openings 34 and 35 are also provided in the threaded insert 5 for the use of such an auxiliary tool.
  • the withdrawal sleeve 14 also has two recesses 36 and 37 in order to support the withdrawal movement by means of an auxiliary tool if necessary.
