- a sprocket is located on the rotor 4 Drive wheel 30.
- the rotor 4 has a collar 4a for receiving of the drive wheel 30. This collar 4a is axially above the end face of the rotor.
- the manufacture of the federal government 4a is complex and expensive because it has to be manufactured by turning operations.
- For alignment of the drive wheel 30 relative to the stator 1 are centering or positioning elements 34 provided in bores in the drive wheel and engage in stator 1. The production of these center holes is also complex and expensive.
- the invention has for its object the generic device to be trained so that they are simple and inexpensive to manufacture can be.
- the drive wheel in the direction of rotation opposite the stator by the centering element and the cooperating counter element aligned.
- the centering element is provided in the peripheral area of the stator, so that it does not have to be provided with center holes. same for also for the drive wheel, which due to the counter element none Center hole needed more. This makes the stator easier Be produced as a sintered part.
- the adjustment device is a camshaft adjuster, with which in known Way a camshaft in an internal combustion engine Motor vehicle can be adjusted. Because the training of such Adjustment device is known, it is only briefly below explained. It has a stator 1, which has a cylindrical jacket 2 has, from which radially inward (not shown) ridges protrude, between which pressure chambers are formed. The webs are lying with their end faces sealing on a base body 3 of a rotor 4 on, which is rotatably connected to a camshaft 5. From the rotor body 3 protrude radially wings 6, with their end faces seal against the inner wall 7 of the stator sheath 2.
- Every Pressure chamber of the stator 1 is a wing, the width of which is smaller than the distance between those delimiting the respective pressure chamber Side walls of the stator webs.
- the rotor 4 can face the stator 1 are rotated relatively far until the rotor blades 6 each according to the direction of rotation on one of the two boundary walls of the Apply pressure chambers of the stator 1.
- the rotor blades 6 are pressurized by a pressure medium from both sides, depending on the desired one Direction of rotation of the rotor 4 relative to the stator 1.
- the print medium is controlled by at least one (not shown) Valve, supplied through holes 8 or 9 in the camshaft 5.
- the pressure medium passes through the radial bores 8, 9 in axially extending feed lines 10, 11 in the camshaft 5. About these supply lines 10, 11 are the pressure medium over radially extending Bores 12, 13 on the corresponding side of the rotor blades 6 promoted.

- the camshaft 5 has a radial distance from its free end outwardly projecting collar 19 on which a flange 20 is seated. He is arranged by the screws 15 distributed over the circumference connected to the stator 1.
- the rotor 4 or its base body 3 has two flat end faces 21 and 22.
- the rotor 4 is advantageously a sintered part. After sintering of the rotor 4, the two flat end faces 21, 22 by one simple grinding process can be finished. With the front 22, the rotor 4 bears against the cover disk 14.
- the opposite End face 21 is provided with a central recess 23, which is used to center the rotor 4 on the camshaft 5.
- a Sleeve 24 serves to separate the feed lines 10 and 11.
- the camshaft 5 is advantageously formed in one piece and carries the federal government 19.
- the camshaft lies with the end projecting over the collar 19 5 with its outer lateral surface 25 on the inner wall 26 of the recess 23 of the rotor. This makes the camshaft 5 easier Radially aligned with respect to the rotor 4.
- the axial alignment is carried out by placing the federal government 19 on the flat face 21 of the rotor 4.
- the recess 23 in the rotor 4 can be provided during the sintering process be, so that a subsequent incorporation of this central Recess 23 in the rotor 4 is not required.
- Not that one ) sprocket is over the flange 20 through the camshaft 5 centered.
- the flange 20 can also be designed as a chain wheel become.
- the collar 19 is used for mounting 27 of the flange 20. So can absorb radial forces caused by the drive and minimizes the friction between the rotor 4 and the stator 1 become.
- the camshaft 5 has an inner diameter that is larger than the outer diameter of the screw 18.
- the sleeve 24 is inserted through which this annulus 28 divided into the two supply lines 10 and 11 for the pressure medium becomes. These feed lines 10, 11 are thus each annular spaces are separated from each other by the sleeve 24.
- FIG 3 shows an adjustment device in the form of a camshaft adjuster, in which a sprocket on the collar 19 of the camshaft 5 30 sits.
- a sprocket on the collar 19 of the camshaft 5 30 sits.
- the radial centering takes place of the rotor 4 relative to the camshaft 5 in that the Camshaft 5 with its end projecting axially beyond the collar 19 on the inner wall 26 of the recess 23 in the end face 21 of the Rotor 4 is present.
- the sprocket 30 is by threaded bolts 31 which are advantageously distributed over the circumference of the stator 1, screwed on the front to the stator 1.
- the sprocket 30 in the circumferential direction with respect to the stator 1 can be aligned, there is at least one centering element on the stator casing 2 33 provided that in the exemplary embodiment a recess is in the outer surface.
- the sprocket 30 is with a Positioning element 34 provided.
- an assembly tool 36 is used for the stator 1. It has a base plate 37 on which an alignment element 38 is provided is.
- the base plate 37 has a triangular depression 39 provided, in which when mounting the assembly tool 36 to the Stator 1 engages the positioning element 34.
- the alignment element 38 of the assembly tool engages 36 into a groove 40 which is in the outside of the casing 2 of the stator 1 is provided and axially between the cover plate 14 and the sprocket 30 extends (Fig. 7). Leave the threaded bolts 31 easy to assemble and the cover plate 14, the stator 1 and that Connect the sprocket 30 firmly together.
- stator 1 Since in the manner described on the positive locking element 34 and the groove-shaped centering element 33 the alignment of stator 1 and Sprocket 30 is carried out in the circumferential direction, the stator 1 in a simpler and be produced inexpensively as a sintered part. After sintering is only the plant side of the stator 1 for the To edit sprocket 30, preferably to grind.
- the alignment element 38 is advantageously spring-loaded, so that the centering in the circumferential direction between the stator 1 and the sprocket 30 regardless of the radial orientation of the chain wheel 30 can take place with respect to the rotor 4.
- Fig. 8 shows the possibility of the sprocket 30 radially opposite Align rotor 4.
- the assembly tool 36 a centering mandrel is used, which has a stepped cross-sectional design having. The gradation is provided so that the sprocket 30 rests on the centering mandrel 36, which in turn with its tapered End 41 on the inner wall 26 of the front recess 23 of the rotor 4 is present.
- dehumidifying chambers 42 and 43 into which a pressure medium is supplied via a feed line 44 becomes.
- the centering mandrel 36 has in the region of the expansion chambers 42, 43 such a thin wall that it is under the pressure of the medium expands elastically. This eliminates any play between the centering pin 36 and the sprocket 30 or the rotor 4 balanced. In this way, the sprocket 30 can be easily and highly accurately align radially with respect to rotor 4.
- the camshaft 5 in the recess 23 of the rotor 4 inserted and rotatably with this end connected to the rotor.
- Any suitable connection can be used for this be provided between the camshaft and the rotor.
- the adjustment device also for existing camshafts can be used that do not protrude into the rotor, it is possible to use adapters, which in this case the camshaft connect to the rotor 4 in a rotationally fixed manner. In such a case, over the adapter piece opposes the pressure medium for rotating the rotor 4 be fed to the stator 1. This has the advantage that the Camshaft itself no special processing or training needed.
