Definitions
- the invention relates to a holder for a, in particular on a commutator or a slip ring engageable with a face, carbon brush, comprising a bent spring element with an optionally U- or L-shaped bent holding portion and a carbon brush receiving support portion, a back side Surface of the carbon brush surface supporting support surface and along side surfaces, in particular two opposite side surfaces or edges of the carbon brush extending holding portions, which are free cut from the support portion of the holder and bent out of the support portion plane portions.
- a corresponding holder is the US 4,157,483 refer to.
- the carbon brush to be fixed on a carrier section of a holder has a tongue-shaped projection on the rear side, which passes through a cutout cut free in the carrier section and is fixed by means of holding sections which are bent out of the plane spanned by the carrier section.
- An appropriate solution is also the US 4,431,933 refer to.
- a holder which consists of an L-shaped spring element, one leg of which has a U-shaped bulge, in which a carbon brush can be fixed.
- the support portion has an opening which is penetrated by a carbon brush to fix it by insulation displacement. Since the carbon brush extends in sections along the back of the support section, a minimum installation depth is required, which can lead to considerable problems especially for small engines. The insulation displacement also results in a notch effect, which can lead to problems with vibrations. Since the rear portion of the carbon brushes passing through the support portion often has a smaller cross-section than the portion facing a commutator, on which the carbon brush rests for power transmission, it is necessary due to the production that the carbon brush material is pressed in the longitudinal direction of the carbon brush to be produced.
- An electric motor for small appliances after the DE 24 13 578 A1 has brackets designed as leaf springs for carbon brushes, each having a prismatic extension which is fixable by notch effect in a section of the leaf spring.
- the present invention is based on the problem, a holder of the type mentioned in such a way that a secure fixing of the carbon brush while avoiding a notch effect is possible, the installation space to be minimized. Also, an optimal use of the carbon brush should be possible.
- the problem is solved by a holder with a carbon brush characterized in that the carbon brush rests with its rear side surface on the cut-free from the support section supporting surface.
- the problem is solved in that the support surface for the planar support of the back surface of the carbon brush is a cut-free surface of the support portion.
- the carbon brush is supported flat on the support section itself, so that the carbon brush does not extend beyond the rear side of the support section. Consequently, the installation depth depends solely on the effective length of the carbon brush interacting with a commutator or slip ring. Furthermore, the carbon brush can be fixed without an insulation displacement connection, so that, in particular, vibrations which have an adverse effect are prevented.
- the holding section further extends in the plane of the support section, so that an increase in the installation depth does not take place. At the same time a high stability is given.
- a particularly secure fixation without the risk of uncontrolled slipping of the carbon brush is given when extend along each side surface of the carbon brush two holding sections as flags.
- the carbon brush can be fixed by clamping over the holding sections.
- the carbon brush itself may be a block carbon brush or a hammer carbon brush.
- a small motor 10 with motor housing 12 and arranged in this electric motor with commutator 14 is shown purely in principle, on which for power transmission carbon brushes 16, 18 abut force.
- the carbon brushes 16 and 18 respectively depart from a holder 20, drawn purely in principle in connection with the carbon brush 16, in the form of a leaf spring known in terms of function, which comprises a holding leg or holding portion 22 and a carrier portion 24 receiving the carbon brush 16.
- the holding portion 22 is fixed in a known manner between bearings and abutments 26, 28 and 30.
- the holding portion 22 on a section U-shaped bent portion 32 which surrounds the bearing 28, whereas the adjacent portions lie flat against the abutments 26 and 30.
- the holder 20 undergoes a unique fixation, wherein due to the bias of the support portion 24 relative to the holding portion 22, the emanating from the support portion 24 carbon brush 16 undergoes the required application of force in the direction of the commutator 14.
- the carbon brush 16 lies with its rear surface 34, which is opposite to the end face 36 abutting the commutator 14, flat on the side facing the commutator 38 of the support portion 24 and is over cut from the support portion 24 and its plane spanning a surface and outwardly bent tabs or lugs 42, 44 fixed, wherein at least in each case a tab or a flag 42, 44 along a side surface 46, 48, 50 of the carbon brush 16 extends.
- the carbon brush 16 is kept out to the required extent and optionally fixed by clamping, without there being an associated with a notch cutting insulation, as is the case in the prior art.
- 1 to 4 is a further, however, from the basic structure of the holder 20 corresponding preferred embodiment of a holder 52 can be seen, which consists of a support portion 54 and a U-shaped bent holding portion 56, wherein the free leg 58 is a U-shaped has curved, outwardly divergent leg having portion 59 which surrounds a bearing corresponding to the bearing 28 of FIG. 5 for fixing the carbon brush holder 52.
- the support portion 54 has a free-cutting surface 60, on which a carbon brush such as the FIGS. 3 and 4 to be removed carbon brush 62, rests flat with its back surface.
- a carbon brush such as the FIGS. 3 and 4 to be removed carbon brush 62
- holding sections 64, 66, 68, 70, 72, 74 are cut free and bent out of the plane spanned by the surface 60 to extend at fixed carbon brush 62 along the side outer surfaces 76, 78, 80, 82 and optionally to hold the carbon brush 62 clamped.
- the clamp fixing is not a mandatory feature, since the flat holding portions or lugs 64, 66, 68, 70, 72, 74 in the true sense alone must provide an axial guide for the carbon brush 62, the force due to the spring action of the support portion 54 on a commutator is applied. Consequently, with properly placed carbon brush 62 alone a guide in the axial direction is necessary without an additional terminals is necessary.
- the carbon brush 62 rests flat on the plane spanned by the support portion 54, namely the support surface 60, on the one hand, even with vibrations occurring a proper concern of the carbon brush 62 is ensured to a commutator. In addition, since the carbon brush 62 does not penetrate the support section 54, it requires a small installation depth.
- cut out of the support portion 54 and bent out of the plane portions or flags can also be such that at least some lines abut for example diagonally opposite edges 84, 90 and 86, 88 of the carbon brush 62.

Abstract
Description
Die Erfindung bezieht sich auf eine Halterung mit einer Kohlebürste, insbesondere an einem Kommutator oder einem Schleifring mit einer Stirnfläche anlegbaren Kohlebürste, umfassend ein gebogenes Federelement mit einem gegebenenfalls U- oder L-förmig gebogenen Halteabschnitt und einem die Kohlebürste aufnehmenden Trägerabschnitt,der eine rückseitige Fläche der Kohlebürste flächig abstützende Abstützfläche sowie entlang von Seitenflächen, insbesondere zweier gegenüberliegenden Seitenflächen oder Kanten der Kohlebürste sich erstreckende Halteabschnitte aufweist, die aus dem Trägerabschnitt der Halterung frei geschnittene und aus von dem Trägerabschnitt aufgespannter Ebene herausgebogene Abschnitte sind. Ferner nimmt die Erfindung Bezug auf eine Halterung für eine, insbesondere an einem Kommutator oder einem Schleifring mit einer Stirnfläche anlegbare, Kohlebürste, umfassend ein gebogenes Federelement mit einem gegebenenfalls U- oder L-förmig gebogenen Halteabschnitt und einem die Kohlebürste aufnehmenden Trägerabschnitt, der eine rückseitige Fläche der Kohlebürste flächig abstützende Abstützfläche sowie entlang von Seitenflächen, insbesondere zweier gegenüberliegenden Seitenflächen oder Kanten der Kohlebürste sich erstreckende Halteabschnitte aufweist, die aus dem Trägerabschnitt der Halterung frei geschnittene und aus von dem Trägerabschnitt aufgespannter Ebene herausgebogene Abschnitte sind.The invention relates to a holder with a carbon brush, in particular on a commutator or a slip ring with an end face can be applied carbon brush, comprising a bent spring element with an optionally U- or L-shaped bent holding portion and a carbon brush receiving support portion having a back surface the carbon brush surface-supporting support surface and along side surfaces, in particular two opposite side surfaces or edges of the carbon brush extending holding portions, which are free cut from the support portion of the holder and bent out of the support portion plane portions.

Der vorliegenden Erfindung liegt das Problem zu Grunde, eine Halterung der eingangs genannten Art derart weiterzubilden, dass ein sicheres Fixieren der Kohlebürste unter Vermeidung einer Kerbwirkung möglich ist, wobei der Einbauraum minimiert werden soll. Auch soll eine optimale Nutzung der Kohlebürste möglich sein.The present invention is based on the problem, a holder of the type mentioned in such a way that a secure fixing of the carbon brush while avoiding a notch effect is possible, the installation space to be minimized. Also, an optimal use of the carbon brush should be possible.
Erfindungsgemäß wird das Problem durch eine Halterung mit einer Kohlebürste dadurch gelöst, dass die Kohlebürste mit ihrer Rückseitenfläche flächig auf der aus dem Trägerabschnitt freigeschnittenen Abstützfläche aufliegt. Für eine Halterung bestimmt für eine Kohlebürste wird das Problem dadurch gelöst, dass die Abstützfläche zum flächigen Abstützen der Rückseitenfläche der Kohlebürste eine freigeschnittene Fläche des Trägerabschnitts ist.According to the invention the problem is solved by a holder with a carbon brush characterized in that the carbon brush rests with its rear side surface on the cut-free from the support section supporting surface. For a holder intended for a carbon brush, the problem is solved in that the support surface for the planar support of the back surface of the carbon brush is a cut-free surface of the support portion.
Erfindungsgemäß wird die Kohlebürste flächig auf dem Trägerabschnitt selbst abgestützt, so dass sich die Kohlebürste nicht über die Rückseite des Trägerabschnittes hinaus erstreckt. Folglich ist die Einbautiefe allein von der wirksamen mit einem Kommutator oder Schleifring wechselwirkenden Länge der Kohlebürste abhängig. Des Weiteren kann die Kohlebürste ohne Schneidklemmverbindung fixiert werden, so dass insbesondere bei Schwingungen sich nachteilig auswirkende Kerbwirkungen unterbunden werden. Der Halteabschnitt verläuft des Weiteren in der Ebene des Trägerabschnitts, so dass eine Vergrößerung der Einbautiefe nicht erfolgt. Gleichzeitig ist eine hohe Stabilität gegeben.According to the invention, the carbon brush is supported flat on the support section itself, so that the carbon brush does not extend beyond the rear side of the support section. Consequently, the installation depth depends solely on the effective length of the carbon brush interacting with a commutator or slip ring. Furthermore, the carbon brush can be fixed without an insulation displacement connection, so that, in particular, vibrations which have an adverse effect are prevented. The holding section further extends in the plane of the support section, so that an increase in the installation depth does not take place. At the same time a high stability is given.
Eine besonders sichere Fixierung ohne die Gefahr eines unkontrollierten Verrutschens der Kohlebürste ist dann gegeben, wenn sich entlang jeder Seitenfläche der Kohlebürste zwei Halteabschnitte wie Fahnen erstrecken. Dabei kann die Kohlebürste über die Halteabschnitte klemmend fixiert sein.A particularly secure fixation without the risk of uncontrolled slipping of the carbon brush is given when extend along each side surface of the carbon brush two holding sections as flags. In this case, the carbon brush can be fixed by clamping over the holding sections.
Bei der Kohlebürste selbst kann es sich um eine Blockkohlebürste oder um eine Hammerkohlebürste handeln.The carbon brush itself may be a block carbon brush or a hammer carbon brush.
Da der Querschnitt der Kohlebürste aufgrund der erfindungsgemäß ausgebildeten Halterung und der damit verbundenen Fixierung der Kohlebürste im rückseitigen Bereich gleichbleibend ist, ergibt sich der Vorteil, dass zum Pressen des Kohlebürstenmaterials eine bevorzugte Richtung nicht einzuhalten ist. Somit ist es ohne Weiteres möglich, Kohlebürsten zu verwenden, die senkrecht oder parallel zur Längsachse der fertigen Kohlebürste gepresst sind.Since the cross-section of the carbon brush is consistent due to the inventively designed holder and the associated fixation of the carbon brush in the rear area, there is the advantage that for pressing the carbon brush material a preferred direction is not met. Thus, it is readily possible to use carbon brushes which are pressed perpendicular or parallel to the longitudinal axis of the finished carbon brush.

In Fig. 5 ist rein prinzipiell ein Kleinmotor 10 mit Motorgehäuse 12 und in diesem angeordnetem Elektromotor mit Kommutator 14 dargestellt, an dem zur Stromübertragung Kohlebürsten 16, 18 kraftbeaufschlagt anliegen. Hierzu gehen die Kohlebürsten 16 und 18 jeweils von einer nur im Zusammenhang mit der Kohlebürste 16 rein prinzipiell eingezeichneten Halterung 20 in Form einer von der Funktion her bekannten Blattfeder aus, die einen Halteschenkel oder Halteabschnitt 22 und einen die Kohlebürste 16 aufnehmenden Trägerabschnitt 24 umfasst. Der Halteabschnitt 22 ist in bekannter Weise zwischen Lager und Widerlagern 26, 28 und 30 fixiert. Hierzu weist der Halteabschnitt 22 einen im Schnitt U-förmig gebogenen Abschnitt 32 auf, der das Lager 28 umgibt, wohingegen die angrenzenden Abschnitte flächig an den Widerlagern 26 und 30 anliegen. Hierdurch erfährt die Halterung 20 eine eindeutige Fixierung, wobei aufgrund der Vorspannung des Trägerabschnittes 24 gegenüber dem Halteabschnitt 22 die von dem Trägerabschnitt 24 ausgehende Kohlebürste 16 die erforderliche Kraftbeaufschlagung in Richtung des Kommutators 14 erfährt.In Fig. 5, a
Die Kohlebürste 16 liegt mit ihrer rückseitigen Fläche 34, die der an dem Kommutator 14 anliegenden Stirnfläche 36 gegenüberliegend verläuft, flächig auf der dem Kommutator zugewandten Seite 38 des Trägerabschnittes 24 auf und wird über aus dem Trägerabschnitt 24 bzw. dessen eine Ebene aufspannende Fläche frei geschnittene und nach außen umgebogene Lappen oder Fahnen 42, 44 fixiert, wobei zumindest jeweils ein Lappen bzw. eine Fahne 42, 44 entlang einer Seitenfläche 46, 48, 50 der Kohlebürste 16 verläuft. Hierdurch wird die Kohlebürste 16 im erforderlichen Umfang geführt gehalten und gegebenenfalls durch Klemmen fixiert, ohne dass eine mit einer Kerbwirkung einhergehende Schneidklemmung vorliegt, wie dies nach dem Stand der Technik der Fall ist.The
Den Fig. 1 bis 4 ist eine weitere, jedoch vom prinzipiellen Aufbau der Halterung 20 entsprechende bevorzugte Ausführungsform einer Halterung 52 zu entnehmen, die aus einem Trägerabschnitt 54 und einem U-förmig gebogenen Halteabschnitt 56 besteht, wobei dessen freier Schenkel 58 einen U-förmig gebogenen, nach außen zueinander divergierende Schenkel aufweisenden Abschnitt 59 aufweist, der zum Fixieren des Kohlebürstenhalters 52 ein Lager entsprechend dem Lager 28 gemäß Fig. 5 umgibt.1 to 4 is a further, however, from the basic structure of the
Der Trägerabschnitt 54 weist eine frei geschnittene Fläche 60 auf, auf der eine Kohlebürste wie die den Fig. 3 und 4 zu entnehmende Kohlebürste 62, mit ihrer Rückseitenfläche flächig aufliegt. Zum Fixieren der Kohlebürste 62 sind Halteabschnitte 64, 66, 68, 70, 72, 74 frei geschnitten und aus der von der Fläche 60 aufgespannten Ebene herausgebogen, um bei fixierter Kohlebürste 62 sich entlang deren Seitenaußenflächen 76, 78, 80, 82 zu erstrecken und gegebenenfalls die Kohlebürste 62 klemmend zu halten.The
Die Klemmfixierung ist jedoch kein zwingendes Merkmal, da die flächigen Halteabschnitte oder Fahnen 64, 66, 68, 70, 72, 74 im eigentlichen Sinne allein eine axiale Führung für die Kohlebürste 62 bieten müssen, die aufgrund der Federwirkung des Trägerabschnittes 54 kraftbeaufschlagt auf einem Kommutator anliegt. Folglich ist bei ordnungsgemäß plazierter Kohlebürste 62 allein eine Führung in axialer Richtung notwendig, ohne dass ein zusätzliches Klemmen notwendig ist.However, the clamp fixing is not a mandatory feature, since the flat holding portions or
Wie insbesondere aus den Fig. 1 und 2 ersichtlich ist, erstrecken sich bei von der Halterung aufgenommener Kohlebürste 62 entlang den Schmalseiten 80, 62 jeweils zwei Halteabschnitte oder -fahnen 68, 70 bzw. 72, 74 und entlang den Breitseiten 76, 78 jeweils ein Halteabschnitt bzw. eine Haltefahne 64, 66, die breiter als die an den Schmalseiten 80, 62 verlaufenden sind. Dabei geht von jeder Längskante 84, 86, 88, 90 der Kohlebürste 62 eine Haltefahne 68, 70, 72, 74 aus, wodurch zusammen mit den entlang verbleibender Längsseitenflächen 76, 78 der Kohlebürste 62 sich erstreckende Fahnen 64, 66 diese so axial geführt ist, dass ein Drehen dieser ausgeschlossen ist.As can be seen in particular from FIGS. 1 and 2, in the case of a
Dadurch, dass die Kohlebürste 62 auf der von dem Trägerabschnitt 54 aufgespannten Ebene, nämlich der Trägerfläche 60 flächig aufliegt, ist einerseits auch bei auftretenden Schwingungen ein einwandfreies Anliegen der Kohlebürste 62 an einen Kommutator gewährleistet. Da zudem die Kohlebürste 62 den Trägerabschnitt 54 nicht durchsetzt, bedarf es einer geringen Einbautiefe.Characterized in that the
Insbesondere ist bei der Verwendung von Blockkohlebürsten der Vorteil gegeben, dass die zur Herstellung der Kohlebürste erforderliche pressfertige Mischung in gewünschter Richtung in Bezug auf die Längsachse der Kohlebürste verpresst werden kann, also z. B. parallel zur Längsrichtung der fertigen Kohlebürste oder senkrecht zu dieser. Hierin sind ergänzende und besonders hervorzuhebende Merkmale zu sehen.In particular, when using block carbon brushes there is the advantage that the press-ready mixture required for producing the carbon brush can be pressed in the desired direction with respect to the longitudinal axis of the carbon brush, ie, for. B. parallel to the longitudinal direction of the finished carbon brush or perpendicular to this. Here are additional and particularly noteworthy features to see.
Anzumerken ist, dass die aus dem Trägerabschnitt 54 ausgeschnittenen und aus deren Ebene herausgebogenen Abschnitte oder Fahnen auch derart verlaufen können, dass zumindest einige linienförmig an zum Beispiel diagonal gegenüberliegende Kanten 84, 90 bzw. 86, 88 der Kohlebürste 62 anliegen.It should be noted that the cut out of the
