Definitions

  • the invention relates to a device for the simultaneous hydraulic expansion of a plurality of longitudinal sections of a hollow shaft for producing non-positive and / or positive connections with elements pushed onto them, such as cams, gears, bearing seats, in the form of a pressure medium probe with a longitudinal pressure medium channel (8) and radial feed bores (9) ) to each longitudinal section of the hollow shaft to be expanded, an expansion arrangement (24) each consisting of a one-piece expansion sleeve (24) covering the entire expansion area, which can be acted upon by pressure medium over substantial parts of its length, the surface of which expands during hydraulic expansion Hollow shaft creates on the inner surface.
  • WO-A-87/00457 Devices of this type are used for fastening parts to hollow bodies.
  • EP 0 257 175 Two processes are known from EP 0 257 175 (prior art according to Article 54 (3) EP Ü), one of which is characterized in that before the parts are applied to the hollow body by heating the parts and / or cooling the A temperature difference is generated in the hollow body and that each part is fastened to the hollow body by expanding the hollow body at least in the area of the fastening point and by subsequently shrinking the parts as a result of the temperature compensation taking place.
  • the second method described in EP 0 257 175 uses a probe which is in the Hollow body is introduced. At the attachment points of the parts to be applied to the hollow body, two sealing rings are arranged per attachment point, which form the expansion space. The sealing rings lie in grooves in the probe. The grooves are connected to a central pressure channel. By introducing pressure medium into the central pressure channel, the hollow body is expanded in a targeted manner between the sealing rings.
  • an expanding device which consists of an expanding sleeve which can be pressurized with a fluid from the inside.
  • the expansion sleeve lies with part of its surface on the inside of the hollow shaft to be expanded.
  • the expanding sleeve is held in position by two sleeves which laterally overlap the expanding sleeve.
  • the particular problem is that for series production Devices must be provided, the seals of which withstand the hydraulic pressures of the order of several thousand bar at least for the duration of one shift, ie for several hundred to several thousand expansion processes, and which are suitable for reliable sealing even on uneven, in particular not to bridge and seal the completely axial interior of the hollow shaft under the conditions mentioned at each expansion point.
  • an easy replacement and replacement of the worn sealing elements of the device should preferably be possible after the service life has been reached.
  • the object of the present invention is to provide such a probe.
  • pressure medium is supplied to each expansion arrangement via the longitudinal feed channel and via the individual radial feed bores, so that all expansion areas of the hollow shaft are pressurized and plastically deformed at the same time.
  • the leakage water that gets into the hollow shaft in the intermediate areas between the expansion areas outside the probe must be drained via radial relief bores located in these areas and a common longitudinal relief channel, so that no pressure build-up and no undesired deformation of the hollow shaft take place in these areas.
  • the expansion arrangement consists in each case of a one-piece expansion sleeve covering the entire expansion area, which can be acted upon with pressure medium from the inside over substantial parts of its length and radially expandable overall is, its surface lies against the inner surface of the hollow shaft for hydraulic expansion.
  • the advantage of such a configuration of the expansion areas lies in an improved possibility of sealing, the required radial path being easily bridged with a suitable choice of material for the expansion sleeves.
  • the sealing areas do not form on the relatively uneven inner surface of the hollow shaft, so that harder materials can be used for this reason alone. Sealing can take place in each case on the outer edge regions with respect to the probe body and / or on the end faces in the manner of labyrinth seals with respect to the adjoining spacer sleeves.
  • An annular space of small radial thickness located within the expansion bushes can be formed as an internal chamber in the sleeve or as a recess on the probe body. In this case, further punctures can also be provided in the probe base body as receptacles for additional sealing elements, without thereby departing from the basic idea of the invention.
  • the invention relates to a device for the simultaneous hydraulic expansion of several longitudinal sections of a hollow shaft of the type mentioned, in which the probe consists of a one-piece probe body with periodically arranged annular grooves, which receives the pressure medium supply and relief channels.
  • a possible first embodiment is characterized in that expansion grooves are accommodated by wide grooves, which are connected to the feed bores, an expansion arrangement each consisting of a one-piece rubber-elastic expansion sleeve covering the entire expansion area, which over a substantial part of its length from the inside Pressure medium can be acted upon and can be expanded radially overall and is sealed in its end regions with respect to the probe body, its surface bearing against the inner surface of the hollow shaft for hydraulic expansion.
  • a probe is shown, which is considerably simplified in its basic structure and in which the sealing elements are cheaper to manufacture at the expense of a slightly more complex assembly, since the basic probe body can be produced without special fits or threads.
  • An improved seal between the expansion sleeve and the probe body can be brought about in that the annular groove on the end faces is undercut in longitudinal section, i. H. z. B. dovetail-like or pawl-like.
  • the figure shows a device with a one-piece probe body with ring grooves with one-piece expansion sleeves.
  • FIG. 1 a shows a probe according to the invention, which shows a probe body 21 of essentially constant diameter in two different versions.
  • a thread 4 onto which a connection piece 5 is screwed, which in turn has an external thread 6 for connection to a pressure line of a pressure generating device.
  • the base body 1 has a thickened probe head 7 at its other end.
  • the connector 5 and the base body 1 are penetrated by a central feed channel 8, of which radial Feed holes 9 go out, which open into screwed-in annular spaces 10 below the expanding sleeves 2.
  • the probe has a relief channel 11, from which radial relief bores 12 extend, which emerge below the spacers 3.
  • the expanding sleeves 24 are sealed by O-rings 13 inserted in ring grooves.
  • the probe body has two annular grooves 22 of different cross-section, which are made directly in the probe body.
  • the annular groove 22a has on its flanks grooves 23, in which an expansion sleeve 24 engages like a pawl.
  • an annular space of small radial strength is screwed into the probe base body, which is connected to a feed bore 9, which starts from the central feed channel 8.
  • the expansion sleeve 24 is preferably made of inelastic material. Essentially the same applies to the annular groove 22b with a trapezoidal cross-section into which the expansion sleeve 24 is inserted.
  • 1 b shows a further embodiment as a detail, in which the dovetail-like cross-sectional shape of the groove 22c is even more pronounced, the flanks having pronounced tips 25.
  • reinforcements 26 made of plastic mass or plastic material are used, which prevent the rubber-elastic sleeve 24c from flowing away under high pressure into the gaps between the hollow body R indicated here and the probe base body 21.
