Definitions
- the invention relates to a bellhousing according to the preamble of claim 1.
- a bellhousing of the type mentioned above is known from German utility model 86 06 067.8.
- the base body is provided in the end face adjacent to the flange body with a closed annular groove, into which a corresponding annular spring protrudes on the opposite end face of the flange body.
- An elastomer material is arranged between the adjoining parts of the base body and the flange body, which provides noise and vibration damping.
- a pump support which serves for the damped connection of a drive motor to a pump and consists of a base body supporting the motor and a cylindrical body supporting the pump. These two cylindrical components are inserted into each other coaxially. Between them there is a relatively large amount of elastomer material for power transmission. The components are specially designed and manufactured parts that are not manufactured in large numbers and cannot be used universally. The connection with the aid of the elastomer material is not made in the area of the end faces of the two load-bearing components.
- the invention is therefore based on the object of creating a bellhousing of the type mentioned at the outset which allows the damped suspension of a pump with the aid of a base body which is present as standard.
- the base body is designed in the region of the end face remote from the motor so that the groove can be machined in if necessary by machining.
- This is not a continuous ring groove, but an opening in the wall sections, i.e. between remaining wall sections or ribs.
- the depth or height of the groove is so great that there is an open opening in the wall sections, the remaining ribs ensuring that the rigidity of the base body is retained.
- the projections then protrude into the openings in the wall sections, which can be designed depending on the forces that are to be transmitted and what other requirements are placed on them. The higher they are, the more space is available for radial support.
- the protrusions are present where the openings are in the opposite base body.
- openings and ribs are arranged at an angle.
- the projections positively project into the openings and, after the elastomer material has been introduced, support the flange body radially on the base body.
- the support is carried out equally in the direction of rotation (torque).
- the tongue and groove connection is provided in the wall sections in the form of openings and projections which lie between the ribs. But it is also possible (claim 2) to provide the tongue and groove connection in the area of the ribs. Then it is not an open opening, but a corresponding groove, into which an equally short tongue protrudes. This groove is created practically when the openings are made by screwing in.
- the invention enables the projections 8 to protrude "as far as possible" into the openings. There is no limit to the amount. In this way, correspondingly high radial loads can be introduced.
- the bellhousing shown in the drawing consists of a base body 1 and a flange body 2. At the end faces on which the two bodies 1 and 2 adjoin one another, they are connected to one another by an elastomer material 3.
- the base body 1 carries the motor, which is not shown, on its side remote from the flange body 2. On its free end face, the flange body carries the pump, which is also not shown.
- the base body In the region of the end face of the base body 1, which adjoins the flange body 2, the base body has radially inwardly projecting ribs 4 of corresponding height or thickness, and between these ribs relatively flat wall sections 5 which connect the ribs to one another.
- this relatively complicatedly designed base body 1 which is kept by default on the bearing, is to be used in a special case in order to fasten a pump in a damped manner, it is only necessary to screw a groove into the lower end face, which is in the area of the ribs 4 with 6 and Area of the wall sections 5 is designated 7. In the area of the wall sections 5, the depth is so great that an opening 7 is formed here, which is correspondingly open inwards.
- a relatively simply designed flange body 2 which, where the openings are provided in the opposite end face of the base body 1, has projections 8 which are relatively high, ie in most cases higher than the wall sections thick , In the embodiment shown, the projections 8 are as high as the ribs 4 are thick.
- projections 9 can also be provided in the area of the groove sections 6 in the ribs, but they are not as high. These projections 9 are surrounded by elastomer material 3 and provide additional support and power transmission.
- a basic body that can be used for damped mounting can be produced in a simple and inexpensive manner from a basic body that can be efficiently produced in large numbers for the undamped mounting of pumps.
- the ribs are designed as stiffening ribs 14 which are configured differently from the embodiment according to FIGS. 1 to 4.
- the depth or height of the groove is so great that an open opening 7 is formed in the wall sections, but only one groove 6 in the area of the stiffening ribs 14, so that the rigidity of the base body is retained.
- the invention can also be implemented without a groove 6 and a tongue (projection 9) being present in the area of the stiffening ribs 14.
- the adjacent faces are smooth. Due to the way in which the openings 7 are produced, it is also sensible to also provide the closed groove 6, since this is produced by screwing in when the openings 7 are produced.
- the projections 8 Due to the design of the projections 8 of any height, there is sufficient radial support of the flange body 2 on the base body 1, in particular under radial loading, so that the vulcanized elastomer material 3 between the wall of the base body 1 and the projections 8 is predominantly subjected to pressure and shear, whereby the extremely unfavorable, pure tensile stresses which are extremely unfavorable with rubber-like elastomers are largely avoided.
Description
Die Erfindung betrifft einen Pumpenträger nach dem Oberbegriff des Anspruches 1.The invention relates to a bellhousing according to the preamble of claim 1.
Ein Pumpenträger der vorstehend genannten Art ist aus dem deutschen Gebrauchsmuster 86 06 067.8 bekannt.A bellhousing of the type mentioned above is known from German utility model 86 06 067.8.
Bei diesem bekannten Pumpenträger ist der Grundkörper in der an den Flanschkörper angrenzenden Stirnfläche mit einer geschlossenen Ringnut versehen, in die eine entsprechende ringförmige Feder an der gegenüberliegenden Stirnfläche des Flanschkörpers hineinragt. Zwischen den aneinander angrenzenden Teilen des Grundkörpers und des Flanschkörpers ist ein Elastomermaterial angeordnet, das für eine Geräusch- und Vibrationsdämpfung sorgt.In this known pump carrier, the base body is provided in the end face adjacent to the flange body with a closed annular groove, into which a corresponding annular spring protrudes on the opposite end face of the flange body. An elastomer material is arranged between the adjoining parts of the base body and the flange body, which provides noise and vibration damping.
Aus der DE 74 20 758 U ist ein Pumpenträger bekannt, der der gedämpften Verbindung eines Antriebsmotors mit einer Pumpe dient und aus einem den Motor tragenden Grundkörper und einem die Pumpe tragenden zylindrischen Körper besteht. Diese beiden zylinderförmig gestalteten Bauteile sind koaxial ineinander gesteckt. Zwischen ihnen befindet sich zur Kraftübertragung eine verhältnismäßig große Menge Elastomermaterial. Bei den Bauteilen handelt es sich um speziell konstruierte und hergestellte Teile, die nicht in großen Stückzahlen hergestellt werden und nicht universell einsetzbar sind. Die Verbindung mit Hilfe des Elastomermaterials erfolgt nicht im Bereich der Stirnflächen der beiden tragenden Bauteile.From DE 74 20 758 U a pump support is known which serves for the damped connection of a drive motor to a pump and consists of a base body supporting the motor and a cylindrical body supporting the pump. These two cylindrical components are inserted into each other coaxially. Between them there is a relatively large amount of elastomer material for power transmission. The components are specially designed and manufactured parts that are not manufactured in large numbers and cannot be used universally. The connection with the aid of the elastomer material is not made in the area of the end faces of the two load-bearing components.
Auf dem hier angesprochenen Gebiet der Verbindung von Motor und Pumpe ist es in den meisten Anwendungsfällen nicht erforderlich für eine Dämpfung zu sorgen, da entsprechende Anforderungen nicht gestellt werden. Die Pumpe wird dann unmittelbar an dem Grundkörper befestigt. Dieser Grundkörper wird als Serienteil hergestellt und in unterschiedlichen Längen auf Lager gehalten. In den wenigen Fällen, in denen eine Dämpfung gefordert wird, ist es dann erforderlich, ei-nen speziellen Grundkörper herzustellen, d.h. ein besonderes Gießwerkzeug zu seiner Herstellung anzufertigen, welches die Nut vorformt oder aber zumindest einen materialaufwendigen Ring anformt, in den eine Nut einzustechen ist. Dieses ist aufwendig und verursacht entsprechend hohe Werkzeugkosten.In the area of motor and pump connection mentioned here, it is not necessary to provide damping in most applications, since corresponding requirements are not made. The pump is then attached directly to the base body. This basic body is manufactured as a series part and is kept in stock in different lengths. In the few cases in which damping is required, one is then required To produce a special base body, that is to say to manufacture a special casting tool for its manufacture, which preforms the groove or at least forms a material-consuming ring into which a groove is to be inserted. This is complex and causes correspondingly high tool costs.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Pumpenträger der eingangs genannten Art zu schaffen, der die gedämpfte Aufhängung einer Pumpe mit Hilfe eines standardmäßig vorhandenen Grundkörpers erlaubt.The invention is therefore based on the object of creating a bellhousing of the type mentioned at the outset which allows the damped suspension of a pump with the aid of a base body which is present as standard.
Diese Aufgabe wird durch das Kennzeichen des Anspruches 1 gelöst.This object is achieved by the characterizing part of claim 1.
Erfindungsgemäß ist der Grundkörper im Bereich der vom Motor abgelegenen Stirnfläche so gestaltet, daß hier im Bedarfsfall die Nut durch mechanische Bearbeitung eingearbeitet werden kann. Hierbei handelt es sich nicht um eine durchgehende Ringnut, sondern um einen Durchbruch in den Wandabschnitten, d.h. zwischen verbleibenden Wandabschnitten oder Rippen. Die Tiefe oder Höhe der Nut ist so groß, daß in den Wandabschnitten ein offener Durchbruch entsteht, wobei die verbleibenden Rippen gewährleisten, daß die Steifigkeit des Grundkörpers erhalten bleibt. In die Durchbrüche der Wandabschnitte ragen dann die Vorsprünge hinein, die je nach dem, welche Kräfte sie übertragen sollen und welche Anforderungen sonst an sie gestellt werden, ausgebildet sein können. Je höher sie sind, um so mehr Fläche steht für eine radiale Abstützung zur Verfügung. Die Vorsprünge sind dort vorhanden, wo bei dem gegenüberliegenden Grundkörper die Durchbrüche sind. Entsprechend sind Durchbrüche und Rippen im Winkel angeordnet. Die Vorsprünge ragen formschlüssig in die Durchbrüche hinein und stützen nach dem Einbringen des Elastomermaterials den Flanschkörper radial an dem Grundkörper ab. Die Abstützung erfolgt gleichermaßen auch in Dreh-(Moment)-Richtung.According to the invention, the base body is designed in the region of the end face remote from the motor so that the groove can be machined in if necessary by machining. This is not a continuous ring groove, but an opening in the wall sections, i.e. between remaining wall sections or ribs. The depth or height of the groove is so great that there is an open opening in the wall sections, the remaining ribs ensuring that the rigidity of the base body is retained. The projections then protrude into the openings in the wall sections, which can be designed depending on the forces that are to be transmitted and what other requirements are placed on them. The higher they are, the more space is available for radial support. The protrusions are present where the openings are in the opposite base body. Correspondingly, openings and ribs are arranged at an angle. The projections positively project into the openings and, after the elastomer material has been introduced, support the flange body radially on the base body. The support is carried out equally in the direction of rotation (torque).
Grundsätzlich ist es ausreichend, wenn die Nut- und Federverbindung in den Wandabschnitten in Form von Durchbrüchen und Vorsprüngen vorgesehen ist, die zwischen den Rippen liegen. Es ist aber auch möglich (Anspruch 2), die Nut- und Federverbindung im Bereich der Rippen vorzusehen. Dann handelt es sich nicht um offene Durchbrüche, sondern um eine entsprechende Nut, in die eine ebenso kurze Feder hineinragt. Diese Nut entsteht praktisch beim Herstellen der Durchbrüche durch Eindrehen.Basically, it is sufficient if the tongue and groove connection is provided in the wall sections in the form of openings and projections which lie between the ribs. But it is also possible (claim 2) to provide the tongue and groove connection in the area of the ribs. Then it is not an open opening, but a corresponding groove, into which an equally short tongue protrudes. This groove is created practically when the openings are made by screwing in.
Eine vorteilhafte Ausführungsform ist weiter Gegenstand des Anspruches 3. Bei dieser Ausführungsform sind die Rippen besonders gestaltet, um für die notwendige Steifigkeit zu sorgen.An advantageous embodiment is also the subject of claim 3. In this embodiment, the ribs are specially designed to provide the necessary rigidity.
Grundsätzlich ermöglicht die Erfindung, daß die Vorsprünge 8 "beliebig weit" in die Durchbrüche hineinragen. Sie sind in ihrer Höhe nicht beschränkt. Hierdurch lassen sich entsprechend hohe Radiallasten einbringen.Basically, the invention enables the projections 8 to protrude "as far as possible" into the openings. There is no limit to the amount. In this way, correspondingly high radial loads can be introduced.
Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung zweier Ausführungsbeispiele näher erläutert.The invention is explained in more detail below with reference to the drawing of two exemplary embodiments.

Der in der Zeichnung dargestellte Pumpenträger besteht aus einem Grundkörper 1 und einem Flanschkörper 2. An den Stirnflächen, an denen die beiden Körper 1 und 2 aneinander angrenzen, sind sie durch ein Elastomermaterial 3 miteinander verbunden.The bellhousing shown in the drawing consists of a base body 1 and a flange body 2. At the end faces on which the two bodies 1 and 2 adjoin one another, they are connected to one another by an elastomer material 3.
Der Grundkörper 1 trägt auf seiner dem Flanschkörper 2 abgelegenen Seite den Motor, der nicht gezeigt ist. An seiner freien Stirnfläche trägt der Flanschkörper die Pumpe, die ebenfalls nicht gezeigt ist.The base body 1 carries the motor, which is not shown, on its side remote from the flange body 2. On its free end face, the flange body carries the pump, which is also not shown.
Im Bereich der Stirnfläche des Grundkörpers 1, die an den Flanschkörper 2 angrenzt, weist der Grundkörper nach innen radial vorstehende Rippen 4 entsprechender Höhe oder Dicke auf, und zwischen diesen Rippen relativ flache Wandabschnitte 5, die die Rippen miteinander verbinden.In the region of the end face of the base body 1, which adjoins the flange body 2, the base body has radially inwardly projecting ribs 4 of corresponding height or thickness, and between these ribs relatively flat wall sections 5 which connect the ribs to one another.
Wenn ein derartiger Grundkörper, so wie er in Fig. 3 dargestellt ist, zum Einsatz kommt um eine Pumpe ungedämpft mit dem Motor zu verbinden, wird die Pumpe unmittelbar an der entsprechenden Stirnfläche des Grundkörpers 1 befestigt.If such a base body, as shown in FIG. 3, is used to connect a pump to the motor undamped, the pump is fastened directly to the corresponding end face of the base body 1.
Wenn dieser standardmäßig am Lager gehaltene relativ kompliziert gestaltete Grundkörper 1 in einem besonderen Fall eingesetzt werden soll, um eine Pumpe gedämpft zu befestigten, so ist es lediglich erforderlich, in die untere Stirnfläche eine Nut einzudrehen, die im Bereich der Rippen 4 mit 6 und im Bereich der Wandabschnitte 5 mit 7 bezeichnet ist. Im Bereich der Wandabschnitte 5 ist die Tiefe so groß, daß hier ein Durchbruch 7 entsteht, der entsprechend nach innen offen ist.If this relatively complicatedly designed base body 1, which is kept by default on the bearing, is to be used in a special case in order to fasten a pump in a damped manner, it is only necessary to screw a groove into the lower end face, which is in the area of the ribs 4 with 6 and Area of the wall sections 5 is designated 7. In the area of the wall sections 5, the depth is so great that an opening 7 is formed here, which is correspondingly open inwards.
Zur Verbindung mit der Pumpe wird ein relativ einfach gestalteter Flanschkörper 2 geschaffen, der dort, wo die Durchbrüche in der gegenüberliegenden Stirnfläche des Grundkörpers 1 vorgesehen sind, Vorsprünge 8 aufweist, die relativ hoch sind, d.h. in den meisten Fällen höher sind als die Wandabschnitte dick. Bei der dargestellten Ausführungsform sind die Vorsprünge 8 so hoch, wie die Rippen 4 dick sind. Nach dem Einbringen des Elastomermaterials 3 steht ein ausreichender Querschnitt zur Verfügung, um die Rippen 8 in radialer Richtung an der zylindrischen Wand des Grundkörpers 1 abzustützen.For connection to the pump, a relatively simply designed flange body 2 is created which, where the openings are provided in the opposite end face of the base body 1, has projections 8 which are relatively high, ie in most cases higher than the wall sections thick , In the embodiment shown, the projections 8 are as high as the ribs 4 are thick. After the introduction of the elastomer material 3 there is sufficient Cross section available to support the ribs 8 in the radial direction on the cylindrical wall of the base body 1.
Wenn es gewünscht wird, können auch im Bereich der Nutenabschnitte 6 in den Rippen Vorsprünge 9 vorgesehen sein, die aber nicht so hoch sind. Diese Vorsprünge 9 sind von Elastomermaterial 3 umgeben und sorgen für eine zusätzliche Abstützung und Kraftübertragung.If desired, projections 9 can also be provided in the area of the groove sections 6 in the ribs, but they are not as high. These projections 9 are surrounded by elastomer material 3 and provide additional support and power transmission.
Beim Betrachten der Fig. 3 wird deutlich, welche Bearbeitung erforderlich ist, um aus einem standardmäßig am Lager gehaltenen Grundkörper 1 einen besonderen Grundkörper 1 herzustellen, der zur gedämpften Lagerung einer Pumpe mit Hilfe eines besonderen Flanschkörpers geeignet ist. Der Aufwand ist relativ gering. Aus einem in großer Stückzahl rationell herstellbaren Grundkörper zur ungedämpften Lagerung von Pumpen kann in einfacher und preiswerter Weise ein Grundkörper gefertigt werden, der zur gedämpften Lagerung einsetzbar ist.3, it becomes clear what machining is required to produce a special base body 1 from a base body 1 held as standard on the bearing, which base body 1 is suitable for the damped mounting of a pump with the aid of a special flange body. The effort is relatively low. A basic body that can be used for damped mounting can be produced in a simple and inexpensive manner from a basic body that can be efficiently produced in large numbers for the undamped mounting of pumps.
Bei der Ausführungsform nach den Figuren 5 und 6 sind die Rippen als im Vergleich zu der Ausführungsform nach den Figuren 1 bis 4 anders gestaltete Versteifungsrippen 14 ausgebildet. Auch bei dieser Ausführungsform ist die Tiefe oder Höhe der Nut so groß, daß in den Wandabschnitten ein offener Durchbruch 7 entsteht, im Bereich der Versteifungsrippen 14 jedoch nur eine Nut 6, so daß die Steifigkeit des Grundkörpers erhalten bleibt.In the embodiment according to FIGS. 5 and 6, the ribs are designed as stiffening ribs 14 which are configured differently from the embodiment according to FIGS. 1 to 4. In this embodiment too, the depth or height of the groove is so great that an open opening 7 is formed in the wall sections, but only one groove 6 in the area of the stiffening ribs 14, so that the rigidity of the base body is retained.
Die Erfindung läßt sich grundsätzlich auch verwirklichen, ohne daß eine Nut 6 und eine Feder (Vorsprung 9) im Bereich der Versteifungsrippen 14 vorhanden ist. Hier sind die aneinander angrenzenden Stirnflächen dann glatt. Bedingt durch die Art und Weise der Herstellung der Durchbrüche 7 ist es aber sinnvoll, auch die geschlossene Nut 6 vorzusehen, da diese beim Herstellen der Durchbrüche 7 durch Eindrehen mit entsteht.In principle, the invention can also be implemented without a groove 6 and a tongue (projection 9) being present in the area of the stiffening ribs 14. Here the adjacent faces are smooth. Due to the way in which the openings 7 are produced, it is also sensible to also provide the closed groove 6, since this is produced by screwing in when the openings 7 are produced.
Durch die Gestaltung der beliebig hohen Vorsprünge 8 ist eine ausreichende Radialabstützung des Flanschkörpers 2 am Grundkörper 1, insbesondere bei radialer Belastung gegeben, so daß das anvulkanisierte Elastomermaterial 3 zwischen der Wandung des Grundkörpers 1 und den Vorsprüngen 8 überwiegend auf Druck und Scherung beansprucht wird, wodurch die bei gummiartigen Elastomeren äußerst ungünstigen, reinen Zugbeanspruchungen weitestgehend vermieden werden.Due to the design of the projections 8 of any height, there is sufficient radial support of the flange body 2 on the base body 1, in particular under radial loading, so that the vulcanized elastomer material 3 between the wall of the base body 1 and the projections 8 is predominantly subjected to pressure and shear, whereby the extremely unfavorable, pure tensile stresses which are extremely unfavorable with rubber-like elastomers are largely avoided.
