Definitions

  • the invention is based, a method and a task Show device for producing a built camshaft, by means of which the operational safety in a simple manner the camshaft in every engine operation is and the camshaft on due to the individual Motor design differently positioned counter bearing can be adjusted.
  • the task is according to the invention by the features of the claim 1 regarding the procedure and the features of claim 6 with respect to the device.
  • the hollow shaft outer diameter of the undeformed Output shaft largely independent of the bearing diameter be selected, whereby with a suitable choice of the outer diameter the hollow shaft is so large that a sufficient bending stiffness for every engine operating situation the hollow shaft is guaranteed, and at the same time so small is dimensioned that the cam due to a sufficient cam belt thickness still has so much rigidity that it has the joining stresses with the joining high pressure application of the Hollow shaft on the one hand and on the other hand in engine operation take whatever load without suffering damage can.
  • the probe 13 consists essentially of a metal rod which a central fluidic with a high-pressure fluid generating system connected pressure fluid guide channel 14. From Pressure fluid guide channel 14 branch axially spaced apart Cross channels 15 and 16, the outlet openings 17 and 18 own in the probe jacket 38. It is conceivable that in the area of Outlet openings 17 and 18 in the probe jacket 38 a circumferential Recess is incorporated, which is an annular pressure chamber open towards the hollow shaft 7. This will make one simultaneous and uniform high pressure application of the respective Widening of the hollow shaft 7 reached, whereby a Uniformity of the expanded point of the hollow shaft 7 achieved becomes.
  • the expansion area 19 and the section 21 are each by the sealing arrangement for pairs of sealing bodies forming the hollow shaft in the form of two axially spaced ring seals 24, 25 axially bounded on both sides by the probe 13 and for their mounting in the probe jacket 38 each two circumferential Recording grooves 26 are formed.
  • the ring seals 24, 25 are supported radially on the inside 27 of the hollow shaft 7 sealing off.
  • the support tool 28 and 29 consists of three jaw-like segments 39, 40, 41, the division joints 42 in contact with the hollow shaft 7 offset by approximately 120 ° to one another are arranged.
  • the probe 13 inserted into the hollow shaft 7, the probe 13 with the Outlet openings 17, 18 of the transverse channels 15, 16 of the pressure fluid guide channel 14 exactly to the respective expansion area 19 and the section 21 are axially aligned.
  • the hollow shaft 7 can, as already described, through the cam bores 9 the cam 4 are threaded through.
  • the cams 4 on a firmly clamped hollow shaft 7 pushed on and positioned there in the intended relative position become.
  • the cams 4 are now representative of the game characterized by the gap 30 in Fig. 2 - on the Hollow shaft 7 positioned. Then the support tools 28 or 29 move radially to the hollow shaft 7 until it on it issue.
  • the applied to the hollow shaft 7 directly to the Widening area 19 of the hollow shaft 7 adjoining sections 31 of the support tool 28 and 29 are the one to be expanded Bearing 20 spanning section 32 of the tool 28 and 29 are connected to each other.
  • Section 32 jumps compared to the contact surfaces 33 of the tool 28 or 29 so far back that he has an annular with the bearing 20 Includes expansion space 34 (Fig. 4a, b).
  • the depository 20 facing surface 35 of the spanning section 32 of the Tool 28 can be die-engraved for the expansion Bearing 20 be formed and is then to the best possible flow of material during expansion ensure highly polished (Fig. 3a, b).
  • the support tool 28 or 29 is in the position of use rigid, i.e. immovable, arranged and covered in such a way the ring seals 24, 25 that a lifting of the abutting them Hollow shaft material under the high pressure fluid of the ring seals 24, 25 is avoided, what else Loss would result in their sealing effect.
  • section 21 and area 19 of the depository 20 can be done simultaneously, but by the in contrast, faster contact of the cam 4 with the hollow shaft 7 to achieve the desired final shape of the bearing 20 on the cams 4 due to the larger expansion axial tensile stresses act, resulting in a reduction in transferable Torques can lead to the cam 4 in engine operation.
  • This can in turn be reduced by the fact that due to the Support by the tool 28 or 29, the hollow shaft 7 such is pinched that the hollow shaft material to expand the Bearing 20 not free from the length of the hollow shaft 7 but is obtained only from the area 19, so that the wall thickness the bearing 20 in its final form compared to its original form is reduced.
  • the reduced wall thickness of the bearing 20 is their wear resistance and rigidity detrimental.
  • the formation of the bearing point can be provided in a favorable manner 20 and the joining process of the cam 4 on the hollow shaft 7 done sequentially, the bearing 20 being formed first becomes.
  • a pressure relief valve is in the transverse channel 15 to the cam 4 37 arranged, which blocks the transverse channel 15, if the bearing 20 is subjected to high internal pressure.
  • the respective cam 4 is placed on the hollow shaft 7 in a provisional Joint position pushed or takes when threading the hollow shaft 7 in the cams 4 a provisional joining position on.
  • the bearing 20 is as desired according to FIG. 4a, b in a simple manner in the form of a bulge 36 by about 1-2 mm expanded. Accordingly, the counter bearing must be formed dome-shaped on the engine, which in turn some Effort means.
  • the tool section 32 in the manner of a die engraving can Bearing 20 when expanding after the hollow shaft material has been applied assume a cylindrical shape on the engraving, which simplifies the formation of the counter bearing of the engine will (Fig. 3a, b).
  • the section reproduced from a die engraving 32 can also be one of the support tool (28) separate tool shape can be formed.
  • the bearing point 20 with a comparatively substantial for expansion printing higher pressure can be calibrated.
  • the Shortening of the hollow shaft 7 occurring during the forming Compliance with the distances of the bearing points 20 from each other Provision of material by using a longer hollow shaft 7 or by gradually expanding the individual storage locations 20 can be countered, the cams 4 between the Bearing positions 20 positioned in their final joining position.
  • the cross channel 15 is released and section 21 of the Hollow shaft 7 in a second forming process with one opposite the expansion pressure described above for the bearing 20, in particular the internal pressure, which is much lower than the calibration pressure acted upon, with the expansion of the Hollow shaft 7 of the cams 4 to form a press fit it is added.
  • the shortening of the hollow shaft 7 in this Second forming is of no importance since the hollow shaft 7 only widens there by about 0.2 mm.
  • the hollow shaft 7 becomes the desired camshaft 2, as from Fig. 5 can be seen.
  • the pressure fluid is released, the Support tools 28 and 29 removed and the probe 13 from the Camshaft 2 pulled out. Then the clamping is released and removed the finished camshaft 2 for further installation.
