- the invention relates to a pressure rolling device and a method for producing ring gears with two axially arranged internal gears, at least one of which is helical. There is also a thread under helical teeth understand.
- Ring gears with internal teeth made of steel alloys and other metallic materials in particular for power transmission on driven wheels from for example, trucks or tractors. Ring gears of this type have on their end faces open ends of externally accessible internal gears on.
- the two internal gears can one have different diameters when the ring gear for example in a gearbox.
- the Ring gear can be a spur gear in which the teeth run parallel to the axis of rotation, have or a helical toothing or a thread.
- WO 96/20050 describes a process for the production described by internally toothed parts, in the case of ring gears with two internal gears are produced by Press rolls the workpiece over forming tools Flow-forming. However, there are only ring gears with double-sided Straight toothing can be produced.
- the invention has for its object the manufacture of internally toothed parts to improve that also parts with two internal teeth, from where at least one is helical, simple are to be produced.
- the invention proposes a pressure rolling device which each have a first and second mold an external toothing, spinning rollers for spinning one on the interconnected molds seated workpiece and a holding means that the Work piece during the press rolling of the first internal toothing on the first mold against twisting secures, has.
- At least one of the molding tools has a helical toothing in which the individual Teeth like a thread at an angle to the Longitudinal axis of the mold run.
- At least one Scraper is provided that the finished Ring gear from the molding tool or tools with helical teeth under relative rotation between the mold and Pushes ring gear. During the production of the ring gear the two molds are non-rotatable with each other coupled.
- the holding means can surround the second molding tool sliding sleeve.
- the sleeve presses that Workpiece against the first mold during the first internal toothing is formed.
- the sleeve holds thereby securing the workpiece on the molds it at the same time against twisting.
- the workpiece is then through the first toothing held on the mold.
- the holding means can also be an embossing element of the first Mold, such as a spur toothing.
- a spur toothing at The workpiece is started by the contact pressure the pressure rollers on this spur toothing pressed so that a rotation of the workpiece without further holding means is prevented.
- a preferred embodiment of the invention stands one of the molds from a tool holder from which is slidably guided in the other mold and attack to take it with you can.
- the two molds are therefore from one Side freely accessible, so that the workpiece is easy can be pushed onto the two molds and the completed ring gear simply from the two Molds can be pushed off. So can too Ring gears are made behind a toothing have a paragraph that has a smaller diameter than the toothing has because the ring gear is stripped from the molds. The molding tool does not have to be pulled out through the paragraph of smaller diameter become.
- this points to the first Mold facing end of the second mold a smaller diameter than the external teeth of the second mold.
- FIG. 1 to 3 points the pressure rolling device 1 a first mold 2 in Shape of a hollow mandrel. This is rotatable on the Shaft of a machine attached. The machine is in the Figures not shown; it is on the left next to the pressure rolling device 1.
- the mold 2 has one at its end facing away from the machine Helical toothing 3.
- a second molding tool 4 runs in the central one Cavity of the first mold 2 and is pending a front opening of the first mold 2 out. It is on a shaft-side tool holder 5 attached, which is located in the central cavity and rotated and moved axially by the machine can.
- the displaceable tool holder 5 engages a conical surface 7 in a corresponding inner cone of the first mold 2 for rotary driving.
- to Creation of a conical clamp between the tool holder 5 and the first mold 2 is with a hollow mandrel 8 operated by the machine against that first molding tool 2 pressed.
- the second mold 4 has parallel teeth at its protruding end 6 which have a smaller diameter than that Helical toothing 3 has.
- the two molding tools 2.4 consist of materials containing chrome or molybdenum, which are hardened and hardened.
- FIG. 1 that is to be formed into a ring gear Workpiece 9 already pre-shaped so that each a short tubular circumferential region 9a or 9b the beginning of the teeth 3 or 6.
- This tubular areas 9a, 9b have a greater wall thickness than the ring gear to be manufactured because the tubular Areas 9a, 9b of greater length and less Wall thickness can be rolled.
- Pressure rollers 10 made of hard metal or HSS steel form it Workpiece 9 on the molds 2.4.
- the pressure rollers 10 are arranged in a radial plane and rotate around its central axis 11 with simultaneous feed.
- the pressure rollers 10 are with a radial Force pressed against the workpiece 9.
- the one so angry Pressure can be, for example, ⁇ 35 t.
- the entire scope of the Machining workpiece 9 evenly must be a rotary Relative movement between the workpiece 9 and the Press rollers 10 take place. You can either use the molding tools 2.4 with the workpiece 9 held thereon can be rotated or the pressure rollers 10 can Workpiece 9 are moved all round.
- a tailstock-side mandrel 12 of the machine has Spring assembly 13 on a centering pin 12a of the riding pin mandrel 12 is arranged.
- the centering pin 12 engages in an end centering opening 14 of the second mold 4.
- the thorn 12 is axially movable. This structure forms an ejection device 15, the tool holder 5 from the Release the conical pressure with the first mold 2 can.
- the tailstock mandrel 12 and the toothing tion 6 of the second mold 4 are of a movable Surrounding sleeve 16 which the workpiece 9th holds non-rotatably on the molds 2.4.
- the workpiece 9 from the tailstock side onto the two molds 2.4 postponed, the ejection device 15 and retracted the holding sleeve 16, that is, from the second Mold 4 are separated.
- the holding sleeve 16 is then advanced. she presses the workpiece 9 against the face of the first Forming tool 2.
- the hollow mandrel 8 on the machine side advanced until the spring assembly 13 against the in position driven tailstock-side mandrel 12 in compressed Condition is present. This will cause the tool holder 5 a conical clamping with the first mold 2 comes in, resulting in a rotationally fixed Coupling of the two molds 2 and 4 leads.
- the spring assembly 13 of the ejection device 15 pressurized.
- the first mold 2, the tool holder 5 with the second mold 4, the hollow mandrel 8, the ejector 15 and the holding sleeve 16 thus form together with the workpiece 9 a rotating unit.
- the pressure rollers 10 are now on the tubular area 9a of the workpiece 9, which is the beginning of the helical toothing 3 of the first mold surrounds, moved up. Each spinning roller 10 rotates about its axis 11. The pressure rollers 10 are placed together on the machine Moves towards the material of the workpiece 9 in front of you and at the same time in the Press helical toothing 3 of the first mold 2, so that ent in the workpiece 9 internal teeth stands. At the bottom of Fig. 1 is a spinning roller 10a in the end position shown, as well as the completed first internal toothing of the workpiece 9.
- Figures 1 and 2 each show two processing steps.
- a scraper 18 which surrounds the first mold 2 against the End face of the ring gear 17 pressed.
- the wiper sleeve 18 points against the ring gear 17 pressing end face on a thrust bearing 19, so that translational, but not rotational, movements be transmitted.
- To detach the ring gear 17 the scraper sleeve 18 against the end face of the ring gear 17 pressed so that it rotates from the first mold 2 is pushed off. At the same time, it slides Ring gear 17 towards the tailstock and is thus from the first Forming tool 42 is rotated.
- the loosened ring gear 17 ' which is shown here in dashed lines, can be removed from the pressure rolling device 1 as soon as the Ejection device 15 is moved to the tailstock side and is thus separated from the second mold 4.
- the second toothing 6 also has a helical toothing a second wiper sleeve is provided, which runs on the ejector 15 to the Ring gear 17 also from the second toothing in the same Way to solve.
- the first mold 102 also has helical teeth 3. However, it is not designed as a hollow mandrel, but rather tubular with a front central opening, into which the second mold 104 engages.
- the second molding tool 104 has parallel teeth 6 and is with the tailstock-side tool mandrel 12 firmly connected.
- the tailstock side tool mandrel For inserting the workpiece into the spinning roller device 101 is the tailstock side tool mandrel with the second mold 104 from the first Forming tool 102 pulled out and the workpiece on the first mold. 102 positioned and then the second mold 104 through the workpiece through into the opening of the first mold 102 inserted.
- a rotatable coupling of the two Molding tools 102, 104 can be made by pressing the both molds 102, 104 or e.g. by not shown Securing pawls take place. Then will as described above, formed the first internal toothing.
- a holding sleeve is not absolutely necessary, since the first mold 102 has an end toothing 116 against which the workpiece from the pressure rollers is pressed at the beginning of the forming process, so that the workpiece and the first mold 102 a non-rotatable Establish connection. In addition, however, can still a holding sleeve may be provided. Also the second internal toothing is shaped as described above. After this the ring gear 17 has been completed, the rotary coupling released between the two molds 102, 104, the scraper sleeve 18 pressed against the ring gear 17 and the first mold 102 from the internal toothing of the Ring gear 17 unscrewed. The tailstock-side tool mandrel 12 is pulled out of the ring gear 17, so that this is removed from the spinning roller 101 can be.
