Definitions

  • the invention relates to a method for producing non-positive connections between nested pipe pieces or for fixing elements pushed onto pipe pieces by permanent radial expansion of several sleeves inserted into them in a coaxial arrangement.
  • Such a method has been used to manufacture assembled shafts such as crankshafts and transmission shafts.
  • One problem here is the printing task on the sleeves that are to be permanently radially expanded. So far, pressure medium probes connected to corresponding pressure generating devices have been used, which bear on the sleeves with pairs of seals and through whose inner channels pressure medium is applied to the sealed sleeves.
  • the disadvantage here is the expensive design of the probes and the limited service life of the seals.
  • the present invention has for its object to provide an improved method and an apparatus for its implementation, in which the generation of pressure is simplified, the problem of seal wear is avoided and, if necessary, the possibility of graduated printing in the various sleeves is opened.
  • the solution to this is that the sleeves are filled with hydraulic fluid and pistons are inserted into their openings, with each other Openings of adjacent sleeves are closed by a common piston and that the internal pressure is increased by approaching the two pistons closing the outward openings of the outer sleeves.
  • a holding device 1 is shown here, in which a pressure P1 is applied in a cylinder 2 in a manner not shown in detail and a stop part 3 is provided at the opposite end thereof.
  • a piston 4 is guided in the cylinder 2 and engages in a first sleeve 5 with a greatly reduced stepped diameter.
  • a further piston 6 is supported on the stop 3 and also engages in a second sleeve 7 with a greatly reduced diameter.
  • Another middle graduated piston 8 engages from the opposite side in the two sleeves 5 and 7.
  • the sleeves are pushed into a first tube 9, onto which an element 10 is pushed in the area of the sleeve 5 and a further piece of tube 11 is pushed in the area of the sleeve 7.
  • Latter are fixed and held in centerings 12, 13, 14 connected to the device 1.
