Definitions

  • the invention relates to a cone crusher with a held on a driven eccentric cone crushing cone, wherein the eccentric bushing rotates about a trained as a journal crusher axis in the radial guidance, which is firmly clamped in a provided in the lower housing lower part receptacle.
  • Cone crushers of this type but also gyratory crushers have long been known from the prior art. According to their purpose, the mass crushing of rocks, they are exposed to heavy loads and correspondingly high levels of wear in harsh environments. In order to ensure reliable operation, the wearing parts, which include in particular the crushing cone held on the cone carrier and also the bearing of the cone carrier, must be replaced from time to time. It is advantageous for the service life, if this work can be carried out on site at short notice. Since the external conditions on the ground, however, are quite uncomfortable and the personnel employed for the maintenance work sometimes becomes impatient due to the failure due to the failure, the handles must be simple and can be carried out without special tooling. In particular, the use of heavy tool due to the risk of damaging the crusher is to be avoided as possible.
  • An apparatus according to the preamble of claim 1 is made WO 2012/140307 A1 known.
  • Object of the present invention is now to design a maintenance-friendly and cost-effective cone crusher, in which the assembly and disassembly of the journal are easily possible even under adverse conditions and without the use of heavy tool.
  • the essential aspect of the invention is to provide the problematic for large cone crusher conical seat of the journal by a To replace cylindrical seat and to clamp the journal in this cylindrical seat in a purely mechanical way non-positively, this tension the same secure hold as a conical seat, while avoiding the disadvantages of consuming (De) assembly and the difficult positioning of the oil passages ,
  • This is inventively achieved in that the crusher axis designed as a journal has a cylindrical upper bearing portion which is clamped in a bore forming the axle journal.
  • the frictional clamping takes place by means of an externally accessible and purely mechanically actuated clamping device, which offers as such a clamping device, the use of a conical clamping set, as is known from the prior art, in particular for the production of shaft-hub connections.
  • the bracing of the journal is not only a single upper clamping device, but by means of two axially spaced from each other and dependent on the bending moment mechanical tensioning devices, which are held with sufficiently large force application surface in the housing base , Accordingly, the journal in addition to the upper bearing portion in addition to a cylindrical lower bearing portion which is clamped by means of the second "lower" mechanical tensioning device in a corresponding lower portion of the annular space provided in the housing lower part.
  • clamping sets can also be formed by individual ring segments, which are arranged symmetrically around the circumference of the journal.
  • axle journal For the simple and precise installation and for the secure hold of the axle journal, it is also advantageous to provide an axial stop in the axle journal, against which the axle journal rests with a correspondingly annular support.
  • the axle journal is then simply inserted from above into the axle journal holder until it stops.
  • the attack defines the so Exact axial mounting position of the journal, in particular, the running in the journal oil lines are reliably positioned.
  • the annular support of the stop is advantageously realized in that, on the one hand, the axle journal and, on the other hand, the axle journal receiver experience a reduction in the diameter in the lower region. The annular support then results at the transition between the two different diameters.
  • conical clamping sets with radially divided pressure rings, which are quasi one behind the other.
  • the clamping sets have a front thrust ring, which faces the inner ring, and a rear thrust ring, wherein both pressure rings are acted upon by their assigned and the inner ring by cross-clamping screws.
  • Another advantage of the invention is the tension in relation to the previous conical bearing significantly lower structural complexity of storage. In addition, it is possible to dispense with the need for the conical storage separate fixation of the vertical mounting position of the axle journal.
  • the invention thus provides a maintenance-friendly and economically viable alternative to the existing type of axle mounting.
  • FIG. 1 First, a section through the head of the cone crusher according to the invention is shown.
  • the crusher abandoned the crushing material between the fixed crushing ring 1 of the upper housing part 2 and the seated on a conical seat of the trunnion 4 crushing cone 3 is crushed.
  • the cone carrier 4 is offset by the driven eccentric bushing 5 in a tumbling motion, whereby the crushing gap 6 between crushing ring 1 and crushing cone 3 changes continuously circulating.
  • the crushed material is crushed by squeezing and impact effect until it can leave the cone crusher through the crushing gap 6.
  • the driven eccentric bushing 5 rotates in a radial guide about a journal 7, which is firmly clamped in the lower housing part 8.
  • a journal 7 For axial support of the cone carrier 4 is a arranged at the top of a cylinder piston 9 spherical thrust bearing 10, which receives the tumbling motion of the cone carrier 4.
  • the cylinder piston 9 is integrated in a frontal bore of the axle journal 7 and allows the axial displacement of the cone carrier 4 with the seated crushing cone 3, which leads to adjustment of the width of the crushing gap 6.
  • the supply of the cylinder piston 9 with hydraulic oil is done via introduced into the journal 7 oil lines 18th
  • the journal 7 is rotationally cylindrical and inserted into the corresponding provided in the housing lower part 8 and designed as a bore axle journal 11, wherein between the journal 7 and the axle journal 11, a sufficiently large game is provided.
  • the axle journal 7 within the axle journal receptacle 11 has this a cylindrical upper bearing portion 15 ( FIG. 2 ), which is braced by means of an upper mechanical tensioning device in the form of a conical clamping set 14.1 in the axle journal receptacle.
  • the conical clamping set 14.1 is received in an opening provided in the axle journal 11 annulus 12.
  • the journal 7 is additionally held by a second lower tension 14.2.
  • this has a cylindrical lower bearing portion 13 which is clamped by means of a corresponding lower mechanical tensioning device in the form of a further conical clamping set 14.2 smaller diameter in a lower portion of the axle journal 11.
  • the clamping set 14.2 receiving annular space 16 is excluded from the journal.
  • the attachment of the axle journal 7 is characterized in that it is clamped over two bending moment dependent, different sized clamping sets 14.1 and 14.2 with sufficiently large force application surface in the housing base 8.
  • the clamping sets are 14.1 and 14.2 installed in two provided and designed as cylindrical guides construction sections between the journal and axle journal recording.
  • the axle journal 7 bears against a stop 17, which the axle journal receiver 11 forms.
  • a transition from a small to a larger bore diameter and corresponding to the journal 7, a transition from a larger to a smaller shaft diameter is provided between the upper bearing portion 15 and the lower bearing portion 13.
  • This stop 17 in the axial direction defines the installation depth of the axle journal 7 in the axle journal receptacle 11.
  • the clamping sets used in this embodiment each have three mutually displaceable elements, wherein the required clamping force is set by means of corresponding screw assemblies.
  • the upper clamping set 14.1 is oriented such that the voltage applied to the upper bearing portion 15 tapered inner ring 20 tapers down to the lower bearing portion 13 out.
  • the lower clamping set 14.2 is oriented such that the lower bearing portion 13 adjacent tapered inner ring 19 tapers up to the upper bearing portion 15 out.
  • clamping sets 14.1, 14.2 are used, each comprising a closed inner ring 20 and two consecutive closed pressure rings 21.1 and 21.2, wherein each of the pressure rings 21.1 and 21.2 is braced by a separate screw 22.
  • the upper clamping set 14.1 is oriented so that the heads of the screws 22 are accessible from the top with the eccentric bush removed, the lower clamping set 14.2 can be braced by screws whose heads are accessible from below.
