Definitions
- the present invention relates to a method for producing a flat commutator with a hub body formed from insulating molding compound, a plurality of conductor segments and an equally large number of carbon segments which form the tread, comprising the following steps:
- the hub body is formed on a radial groove having a conductor blank, the grooves being filled with molding compound; the composite part of the conductor blank and the hub body is then machined on the end face of the conductor blank facing away from the hub body; A carbon ring disk is applied to the machined end face of the composite part to form a commutator blank, producing electrically conductive connections to the conductor blank or the conductor segments resulting therefrom; and the carbon ring disk is divided into carbon segments by cuts which extend into the molding compound filling the grooves, the blank of the conductor being subdivided into the conductor segments either when it is machined on the end face by opening the grooves filled with molding compound or by cutting cuts introduced later.
- the present invention further relates to a face commutator produced by this method.
- Flat commutators are known in various designs and are used.
- a typical flat commutator is shown, for example, in DE-OS 4140475.
- a typical area of application for flat commutators is electric motors of fuel pumps (cf. e.g. DE-OS 19652840 and DE-OS 197526326).
- flat commutators with a carbon running surface are widely used here.
- the carbon segments are carried by copper conductor segments in order to be able to contact the winding ends of the rotor winding with the carbon segments without difficulty.
- a carbon ring which is later divided into carbon segments by separating cuts, can be formed on the latter directly by sintering powdered carbon in which the conductor blank is embedded.
- a prefabricated carbon ring washer is placed on an end face of the conductor blank or the conductor segments, there electrically soldered and mechanically firmly connected and later divided into the carbon segments by separating cuts, which may also divide the conductor blank into the conductor segments. Both procedures are set out, for example, in DE-OS 19652840.
- the hub body can be molded onto the conductor blank before (see WO97 / 03486) or after (see DE-OS 4028420) the carbon ring disk is soldered onto the conductor blank.
- a method of the type mentioned at the beginning can be found in the aforementioned WO97 / 03486.
- the method known from this document for producing a flat commutator is characterized in that those separating cuts with which the carbon ring disk is divided into carbon segments are cut into the molding compound of the hub body extend into it without cutting the blank. This is achieved by opening the radial grooves on the back of the conductor blank, which are wider than the separating cuts and filled with molding compound, before the carbon ring disk is applied to the composite part comprising the conductor blank and the hub body. As a result, in the area of the opened radial grooves, the carbon ring disk lies directly against the molding compound of the hub body.
- the task on which the present invention is based is derived from creating a method of the generic type which is suitable for producing flat commutators with the longest service life.
- this object is achieved in that the carbon ring disk is glued to the machined end face of the composite part consisting of the conductor blank and the hub body.
- the adhesive connection of the carbon ring disk and the composite part consisting of the conductor blank and the hub body which is characteristic of the present invention, manifests itself in various ways in an increased service life of the flat commutator according to the invention, compared with those according to the prior art.
- the adhesive connection provided according to the invention is not only between, as is known from the soldered connection used in the prior art acts on the conductor blank, in particular its end face, and the corresponding areas of the carbon ring disk; rather, the adhesive connection also extends to those areas in which the carbon ring disc lies against the molding compound of the hub body. This applies in particular to the contact surface between the carbon ring disk and a central fixing web made of molding compound.
- an advantageous side effect of using the present invention is that the effort associated with the production of the flat commutator is less than when using known methods.
- the decisive factor here is that the complex pretreatment of the carbon ring disk required in the prior art in order to make it solderable at all is eliminated.
- the carbon ring disk does not need to be metallized, for example by vapor deposition of a thin copper layer.
- the present invention also proves to be advantageous insofar as, with a suitable choice of the adhesive, the risk existing in the prior art that when the winding wires are welded to the conductor segments, their temperature may exceed the softening point of the solder and the carbon segments may slip as a result .
- the adhesive connection provided according to the invention and which extends over the entire machined end face of the composite part consisting of the conductor blank and the pressing body also acts between Carbon ring disc and the press material filling the opened radial grooves.
- the adhesive connections (also) between the carbon segments and the molding compound filling the radial grooves prevent aggressive media such as fuel containing methanol or ethanol from penetrating into the area of the contact surfaces between the conductor segments and the carbon segments from the separating cuts.
- this development of the present invention solves a problem with simple means which, in the prior art, could only be solved by using complex pretreatment and soldering methods, in particular using silver.
- thermoplastic powder with a melting point above 290 ° C. is particularly preferably used as the adhesive (see below), a wide variety of substances can be used as an adhesive in the context of the present invention.
- a thermoplastic plastic in particular hard coal and petroleum tars and peche, natural resins, synthetic resins and thermosetting plastics, which are produced by polymerisation, polyaddition or polycondensation and, if appropriate, by natural substances, e.g. B. vegetable or animal oils or natural resins have been modified, as well as all artificial resins by Modification (e.g. esterification, saponification) of natural resins were produced.
- Blends of the above substances are also suitable.
- the adhesive based on a mixture of powder of at least one thermoplastic and at least one thermosetting plastic is particularly favorable. This proves to be very advantageous in the manufacture of the flat commutator, because melting of the adhesive and thus slipping of the carbon segments during welding of the connections is effectively prevented.
- the adhesive is filled with an electrically conductive metallic or non-metallic filler in the form of powders, chips or fibers.
- a corrosion-resistant metal powder is particularly preferably used, preferably silver or silver-coated copper powder with a grain size range of 40 to 90 ⁇ m.
- the proportion of the filler in the filled adhesive can be between 5 and 95, preferably between 25 and 50 percent by mass.
- a preferred further development of the method according to the invention is characterized in that, when the composite part is machined on the end face, an annular inner fixing web consisting of molding compound is left standing, the outer diameter of which decreases in the machining direction.
- the maximum outer diameter of the fixing web is preferably larger than the inner diameter of the bore of the carbon ring disk before it is applied to the composite part, the oversize being about 0.1 mm for commutators of average size.
- the outer end edge of the fixing web at an angle is particularly preferred chamfered between 10 ° and 45 °.
- the fixing web specified above has an advantageous effect both in the manufacture of the flat commutator and in terms of its service life. As part of the manufacturing process, the fixing web fixes the carbon ring disc placed on the composite part due to its dimensions.
- the adhesive introduced between the opposing end faces of the carbon ring disc on the one hand and the composite part on the other hand is held in place and prevented from escaping even when it is a dry powdery material.
- the fixing web also takes over a centering or adjusting function for the carbon ring disk, so that the carbon ring disk can be manufactured to final dimensions before the connection with the composite part in the external dimensions.
- the excess of the fixing web compared to the diameter of the bore in the carbon ring disc also prevents the adhesive from escaping in the region of the bore in the carbon ring disc when it is pressed onto the composite part.
- the fixing web tapers in the axial direction, whereby an annular pocket suitable for receiving adhesive is formed.
- the cross-sectional shape of the pocket which can in particular be wedge-shaped, also favors the adhesion of the carbon segments of the finished commutator.
- the hardened adhesive accumulated in the adhesive pockets has a positive effect in that it prevents the entry of aggressive substances radially from the inside into the contact area formed between the carbon segments and the conductor segments.
- the composite part comprising the conductor blank and the hub body has an outer ring jacket made of molding compound which surrounds the conductor blank and which is also used for side processing of the composite part is processed before applying the carbon ring washer.
- an outer ring jacket made of molding compound which surrounds the conductor blank and which is also used for side processing of the composite part is processed before applying the carbon ring washer.
- the conductor blank used in the context of the present invention particularly preferably has an inner ring web, an outer ring web and radial webs on its end face to be machined, the webs projecting from the rest of the end face, so that pocket-shaped depressions are formed between the webs.
- the number of radial webs corresponds to the number of radial grooves arranged on the opposite side, which in turn is identical to the number of carbon segments and the conductor segments.
- the groove bases of the radial grooves can run essentially in the same plane as the end face between the webs.
- the conductor blank has a particularly high torsional stiffness with a comparatively low use of material, and at the same time the material removal required when the composite part is machined on the end face is comparatively low. So A conductor blank shaped in this way can be manufactured particularly cost-effectively, by molding around the molding of the hub body to form a particularly precise composite part with molding compound and to process the end part particularly economically in the context of the composite part.
- the present invention can be used in a special way in the context of a method for the production of flat commutators, in which the composite part comprising the conductor blank and the hub body is machined on the face side until the grooves filled with molding compound open, in order to divide the conductor blank into the conductor segments, it is by no means restricted to this procedure.
- the composite part is machined on the end face, but without the grooves filled with molding compound being opened; Rather, in this method, the conductor segments are still connected to one another even after the end face machining of the composite part, specifically via thin connecting webs in the area the reasons for use. These connecting webs are only severed after the carbon ring disk has been glued to the composite part, preferably in one step together with the subdivision of the carbon ring disk into carbon segments.
- FIG. 1 is a perspective view of a conductor blank
- FIG. 2 shows a tangential section through the conductor blank according to FIG. 1 along the line II-II,
- FIG 3 shows the composite part formed from the conductor blank and the hub body after it has been machined on the end to divide the conductor blank into eight conductor segments
- FIG. 5 is a perspective view of the carbon ring disc before it is glued to the composite part of FIG. 3,
- FIG. 6 is a perspective view of a cut commutator blank produced by gluing the carbon ring disk according to FIG. 5 onto the composite part according to FIG. 3,
- FIG. 7 shows an axial section through the commutator blank according to FIG. 6 after a circumferential groove has been screwed in on the outer circumference in the region of the adhesive layer
- FIG. 8 shows a tangential section through a flat commutator, which has arisen from the commutator blank according to FIG. 7 by introducing separating cuts dividing the carbon ring disk into carbon segments;
- FIG. 9 to 13 explain a variant of the manufacturing method illustrated in FIGS. 1 to 8 and explained below with reference to this.
- the conductor blank 1 illustrated in FIGS. 1 and 2 has an essentially cup-shaped shape. In terms of its basic structure, it thus corresponds to the state of the art, as can be gathered, for example, from WO97 / 03486.
- the conductor blank according to FIGS. 1 and 2 is characterized by an inner ring web 2, an outer ring web 3 and eight radial webs 4 on the end face to which the carbon ring disk is later to be glued.
- a pocket-shaped depression 5 is formed between each two adjacent radial webs 4 and the sections of the inner ring web 2 and the outer ring web 3 connecting them to one another.
- the end face formed by the bottoms 6 of the pocket-shaped depressions 5 between the webs lies in a plane normal to the axis.
- the radial grooves 7 formed on the opposite side of the conductor blank 1 have a trapezoidal cross section. They run parallel to the radial webs 4 and have a depth such that their groove base 8 lies essentially in the same plane as the bottoms 6 of the pocket-shaped depressions 5.
- FIGS. 3 and 4 illustrate the composite part 10 consisting of the conductor blank according to FIGS. 1 and 2 and the molded part 10 formed thereon and forming the hub body 9 after it has been machined on the end face, namely on the end face shown in FIG. 1.
- the previously formed molding of the hub body which is made of molding compound, corresponds to the prior art, as can be seen, for example, from WO97 / 03486, so that no explanations are required at this point.
- the end processing of the composite part 10 includes its end turning for Removal of the inner ring web 2, the outer ring web 3 and the radial webs 4. After the webs have been removed, the conductor blank has a closed, annular, flat end face in the plane formed by the bottoms 6 of the pocket-shaped depressions 5.
- This ring surface is turned further in the following, until the grooves 7 in the region of their groove base 8 are completely open.
- the position of this processing plane 11 is illustrated in FIG. 2. Obviously, a minimal material removal of the closed, ring-shaped, flat end face of the conductor blank is sufficient to open the grooves 8 filled with molding material. If the grooves 7 were formed even deeper than shown in FIG. 2, it would even be possible to open the radial grooves while the inner ring web 2, the outer ring web 3 and the radial webs 4 are still being removed.
- the conductor blank illustrated in FIGS. 1 and 2 has been divided into eight separate conductor segments 12. Between each two conductor segments 12 there is a rib 13 of the hub body 9 formed from pressed material.
- the molded hub body 9 comprises an inner sleeve 15 which is arranged radially within the central bore 16 of the conductor blank 1.
- the conductor blank 1 can be machined on the end face over its entire radial extent and, at the same time, the fixing web 14 can be left radially inside the central bore 16 of the conductor blank 1.
- FIG. 3 it is further illustrated that the hook elements 18 formed on the wall sections 17 of the conductor segments 12 have been bent out of their radially protruding position shown in FIG. 1.
- the outer circumference 20 of the carbon ring disk 19 is matched exactly to the outer circumference 21 of the composite part 10 machined on the end face in such a way that the outer diameter of the carbon ring disk 19 corresponds to the outer diameter of the composite part 10 in the region of the machining plane 11.
- the diameter of the bore 22 of the carbon ring disk 19 is approximately 0.1 mm smaller than the outer diameter of the fixing web 14 of the composite part 10. This favors the fact that the carbon ring 14 is already securely positioned during the manufacturing process and between before the bonding with the composite part 10 is carried out the existing adhesive cannot escape from the parts to be glued together.
- FIG. 6 shows the commutator blank 23 formed from the composite body 10 and the carbon ring disk 19 glued on.
- the outer surface 24 of the fixing web 14 tapers from the area of the maximum diameter in the direction of the machining plane 11; in other words, the outer diameter of the fixing web 14 decreases from the area of a maximum diameter in the direction of the machining plane 11.
- a circumferential annular groove-like depression is formed on the outer circumference of the fixing web 14, which is filled with adhesive when the carbon ring disk 19 is glued to the composite part 10.
- the adhesive bag 25 formed in this way with an approximately wedge-shaped cross section favors the mechanically firm and tight connection of the carbon ring disk 19 and the carbon segments resulting therefrom with the composite part 10. Furthermore, the chamfer 26 of the fixing web 14 can be seen, which is important in view of the excess of the fixing web compared to the bore 22 of the carbon ring disk 19 in order to damage the Exclude carbon ring washer during assembly.
- the carbon ring disk 19 is glued to the composite part 10, as was explained in detail above.
- a mixture of thermoplastic plastic powder (PPS) and thermosetting plastic powder is used as the adhesive.
- PPS is characterized by its high temperature resistance and its high resistance in fuels.
- One of the two adhesive surfaces is dusted with the adhesive powder waste as well as with metal powder.
- a copper powder with a grain size range of 40 to 90 ⁇ m, silver-plated for corrosion reasons, is used as the metal powder, the task of which is to ensure sufficient conductivity.
- the proportion of metal powder in the adhesive filled with it is between 25% and 50%. Just enough plastic powder is sprinkled on the adhesive surface that the surface is evenly and densely covered. Then the composite part 10 and the carbon ring disk 19 are joined and heated to approximately 300 ° C.
- the adhesive melts and penetrates into the pores of the carbon ring disk 19. After a short holding time of approx. 5 seconds, the mixture is cooled. The adhesive that has penetrated into the pores solidifies, thus creating a mechanical positive connection. This achieves optimal adhesion that is superior to that of soldering.
- the metal powder forms the contact bridges between the conductor segments 12 and the carbon ring disk 19, which causes a very low contact resistance.
- the thickness of the adhesive layer 27 is a maximum of 500 ⁇ m, whereby, as explained above, the adhesive has partially penetrated into the pores of the carbon ring disk 19 and has hardened there.
- the particles responsible for the electrical conduction are embedded in the adhesive and are thus protected against electrical and chemical reactions with the surrounding medium. Furthermore, the contact surface area assigned to each individual conductor segment 12 is sealed radially on the inside, in the area of the fixing web 14, and in the circumferential direction in the area of the ribs 13 by gluing the carbon ring disk 19 with molding compound, against the penetration of aggressive media.
- a circumferential groove 29 is screwed in in the region of the adhesive layer 27 after the adhesive has hardened.
- the commutator blank 23 is thus prepared so far that only the carbon ring disk 19 is to be subdivided into carbon segments 31 by separating cuts 30.
- the separating cut 30 extends into the molding rib 13.
- the fixing web 14 is also divided by the separating cuts 30, so that in particular a current flow between the individual conductor segments via the adhesive filled with metal particles is excluded.
- 8 shows in a tangential section the area between two conductor segments 12 and the carbon segments 31 assigned to them.
- the separating cut 30, which divides the carbon ring disk into the two carbon segments 31 shown here, extends into the press rib 13 of the hub body 9 extends and thereby also cuts the adhesive layer 27. It can also be seen that the width of the separating cut 30 is less than the width of the press rib 13. In this way, immediately adjacent to the separating cut 30, each of the two carbon segments 31 is firmly bonded to the press rib 13 of the hub body 9, which causes the carbon segments to break out 31 effectively prevented at their base when introducing the separating cuts 30.
- FIGS. 9 to 13 illustrate an alternative to the manufacturing method explained above. You correspondingly to a considerable extent Figures 2, 3, 4, 7 and 8. to the extent that they correspond to those figures, reference is made to the above explanations. The following description is therefore limited to the significant differences of the manufacturing method illustrated in FIGS. 9 to 13 compared to the manufacturing method according to FIGS. 1 to 8.
- FIGS. 9 and 2 show that the radial grooves 7 'in the case of the variant described here have a smaller depth than the radial grooves 7 of the manufacturing method explained above. It follows from this that the grooves 7 'are not opened during the end machining of the composite part 10' consisting of the conductor blank and the hub body up to the machining plane 11. Rather, the later conductor segments of the conductor blank remain connected to one another via connecting webs 32.
- a preferred measure for the thickness of the connecting webs 32 is approximately 0.3 mm in the case of a flat commutator of typical dimensions.
- the carbon ring disk is thus glued to the annular surface 33 of the conductor blank 1 ′ produced by the machining on the end face.
- the subdivision of the conductor blank l 1 into the conductor segments 12 ' takes place in one operation with the subdivision of the carbon ring disk into carbon segments 31' by separating cuts 30 ', which extend into the grooves 7' into the molding compound of the hub body.
