Definitions
- the invention relates to a method for the production of assembled camshafts according to the preamble of claim 1 and an apparatus for carrying it out.
- the cam belt undershoots a certain thickness, can a durable joining of the cam on the hollow shaft in achieving a Preßverbundes between the hollow shaft and cam can not be achieved because the cam is not sufficient rigidity has more to absorb the joining stress.
- an average pipe outside diameter to comply with, on the one hand, the camshaft and the Bearing has sufficient rigidity and the bearing point a sufficient wear resistance is given and
- the cam belt is still strong enough to absorb of the cam for the joining tension. This is constructively feasible.
- the bearing sleeves may occasionally only very thin (about 1mm) be measured, creating a Durability on the hollow shaft under load in motor operation practically is not given.
- the invention is based on the object, a method and a Show apparatus for producing a built-up camshaft, by means of which or in a simple way the reliability ensures the camshaft in each engine operation is and the camshaft is due to the individual Engine design differently positioned thrust bearing arbitrary can be adapted.
- 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 of this is sized so large that a sufficient flexural rigidity 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 this the joint stresses in the mating hydroforming the Hollow shaft on the one hand and on the other hand in engine operation gleichweicher Load even without suffering damage can.
- Fig. 1 is a device 1 for the production of a built Camshaft 2 shown which a plurality of successively arranged Tools 3 for positioning and holding the cams 4, which is pneumatically aligned in the tools 3 become.
- These tools 3 are located between one Hohlwellenzu evaluation 5 and a clamping tool 6, the Hollow shaft 7 at one end with a gripper 8 in a centric Position fixed.
- the hollow shaft 7 is doing before the fixation through the feed 5 through the cam holes 9 in the Tools 3 held cam 4 threaded through.
- On hollow shaft averted Page 10 of the clamping tool 6 is a with attached to an insertion funnel 11 provided probe insertion 12, by means of which a lance-shaped probe 13 (FIG. 2) exactly centered in the clamped hollow shaft 7 can be inserted is.
- the probe 13 consists essentially of a metal rod, the a central with a fluid high pressure generating plant fluidly connected pressure fluid guide channel 14 has. From Pressure fluid guide channel 14 branches axially spaced apart Transverse channels 15 and 16 from, the outlet openings 17 and 18th have in the probe shell 38. It is conceivable that in the field of Outlet openings 17 and 18 in the probe sheath 38 has a circumferential Recess is incorporated, which is an annular forms the hollow shaft 7 open pressure chamber. This will be a simultaneous and uniform high-pressure admission of the respective Aufweitstelle the hollow shaft 7 reaches, creating a Contour equality of the expanded location of the hollow shaft 7 achieved becomes.
- the expansion area 19 and the section 21 are each by the sealing arrangement for the hollow shaft forming sealing body pairs in the form of two axially spaced annular seals 24,25 axially bounded on both sides, which are supported by the probe 13 and for the holder in the probe sheath 38 each two circumferential Receiving grooves 26 are formed.
- the ring seals 24,25 are supported radially on the inner side 27 of the hollow shaft. 7 sealing off.
- the seal body pairs includes the Sealing arrangement for the bearing 20, a support tool 28th (Fig. 3a, b) and 29 (Fig. 4a, b), in the position of use on the outside the hollow shaft 7 circumferentially, leaving the widening Area 19 of the hollow shaft 7 rests rigidly and the ring seals 24,25 covers.
- the support tool 28 or 29 consists of three jaw-like segments 39,40,41, their division joints 42 offset in contact with the hollow shaft 7 by about 120 ° to each other are arranged.
- the probe 13th inserted into the hollow shaft 7, wherein the probe 13 with the Outlet openings 17,18 of the transverse channels 15,16 of the pressure fluid guide channel 14 exactly on the respective expansion area 19 and the portion 21 are axially aligned.
- the hollow shaft 7 can previously as already described by the cam holes. 9 the cam 4 are threaded through. Alternatively, however, can equally the cams 4 on a tightly clamped hollow shaft 7 postponed and positioned there in the intended relative position become.
- the cams 4 are now with play - representative characterized by the clearance gap 30 in Fig. 2 - on the Hollow shaft 7 positioned. Then the support tools 28 and 29 moved radially to the hollow shaft 7, until this at her issue.
- the support tool 28 or 29 is in the position of use rigid, so immovable, arranged and covers it in such a way the ring seals 24,25, that a lifting of the voltage applied to these Hollow shaft material under the fluid high pressure is avoided by the ring seals 24,25, what else a Loss whose sealing effect would result.
- the formation of the bearing 20 and the joining operation of the cam 4 on the hollow shaft. 7 take place sequentially, wherein the bearing 20 first formed becomes.
- a pressure relief valve 37 is arranged, which blocks the transverse channel 15, when the bearing 20 is subjected to internal high pressure.
- the respective cam 4 is on the hollow shaft 7 in a provisional Fuhrage pushed or takes in a threading the hollow shaft 7 in the cam 4 a provisional Fügelage on.
- the bearing 20 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, however, the counter bearing must be formed dome-shaped on the engine, which in turn some Effort means.
- the transverse channel 15 is released and the section 21 of Hollow shaft 7 in a second forming process with an opposite the above-described expansion pressure for the bearing 20, in particular the calibration pressure much lower internal high pressure acted upon by the local expansion of the Hollow shaft 7 of the cam 4 to form a Preßverbundes she is joined.
- the shortening of the hollow shaft 7 at this Second transformation is not significant because the hollow shaft. 7 there only expands by about 0.2 mm.
- Using of the support tool 29, it is useful to further widening to avoid during the joining process, in the transverse channel 16 also provide a pressure relief valve, this locks in the mentioned joining.
- the hollow shaft 7 is the desired camshaft 2, as shown Fig. 5 can be seen.
- the pressurized fluid is released, the Support tools 28 and 29 removed and the probe 13 from the Camshaft 2 pulled out.
- the clamping is released and the finished camshaft 2 removed for further installation.
