Definitions
- the invention relates to a bell which is made of aluminum or an aluminum alloy and in which the pitch is determined and which has a long-lasting reverberation.
- Bells have been used for centuries to produce musical tones, to signal the time or to announce an event, as well as in orchestras, as a melodic percussion or puncturing musical instrument.
- the bells in their familiar forms actually serve as idiophonic musical instruments.
- the bell can be viewed as a three-dimensional plate which, when struck, causes two-dimensional vibrations.
- Two node line systems are formed in the course of the two-dimensional oscillation, namely the system of the longitudinal node lines and the system of the circular node lines.
- the longitudinal knot line system consists of knot lines located in vertical planes, the vertical planes containing the vertical longitudinal axis of the bell (in its freely hanging position on the hanger); the node lines have an approximately identical shape to the generatrix of the bell shell.
- the longitudinal node lines divide the bell mantle into 4 to 12 zones along the periphery. Of the longitudinal nodal lines, the vibrations on that nodal line have the greatest amplitude, which from the impact means, e.g. B. from the bell handle, receives the stop.
- the other node line system which arises during the vibration consists of circular node lines in planes perpendicular to the longitudinal axis of the bell along the longitudinal axis at intervals from one another, the centers of the circular node lines lying in the longitudinal axis.
- the vibration with the greatest amplitude takes place at the lower edge of the bell, on the flange.
- the flange can be viewed as if it were the free edge of a clamped beam or plate.
- the vibration, the sound, emanate from the flange.
- the whole bell oscillates, with the exception of the clamping point, which is in the middle at the top.
- the resulting tone consists of two parts.
- the first to appear is the beat tone, which is a single short tone with a fixed pitch and metallic sound.
- the bell sound is considered to be the bell sound.
- the impact sound stops after a short time, the decay takes place extremely quickly.
- the beat sound is the result of an overtone sequence, i.e. their subjective basic voice.
- the so-called bell button that precedes the complete reverberation of the beat tone, which can be identified with the solid vibration condition of the bell casing and has the character of a polyphonic sound and sinks very slowly.
- This sounding sound consists of several components, generally the fundamental, the third, the fifth and the upper octave, of which the fundamental is the longest; the others weaken relatively quickly.
- the two bell sounds have two tones; if the impact sound is largely metallic, which means numerous non-harmonic overtones, the pitch is uncertain.
- the sound is softer and quieter. As a result of the gradual decay, the sound becomes clearer, the tones (overtones) decay one after the other; at last only the basic tone is audible.
- the sound image described here depends exclusively on the design of the bell shell; it is not influenced by the strength of the stroke nor by the composition of the bell material, since these only determine the number and strength of the overtones.
- the pitch is mainly determined by the material and the diameter of the bell, the weight of the bell being proportional to the diameter. It is considered to be advantageous if the prescribed or desired pitch can be achieved with a bell with the smallest possible diameter and the lowest possible weight.
- the smallest diameter and the lowest weight can be achieved with gold as the material at a given pitch, with a larger diameter and weight the desired pitch can be achieved with silver as the basic material. Due to the high prices, neither silver nor gold can be used as raw materials.
- the bell bronze with the Cu + Sn composition is the cheapest of the copper alloys; the other copper alloys do not lead to the desired result.
- the bells made of aluminum or aluminum alloys in the known construction showed unacceptably short periods in terms of reverberation times; the sound wasn't pleasant either.
- the invention solves the problem of creating a bell construction which enables the use of the relatively cheap aluminum or aluminum alloys for their production and which, as a success, allows the production of bells, either as a single piece or in series, quickly and with a significant reduction in costs .
- Another requirement is that the bell can be tuned in easily and quickly and that its desired pitch can be set.
- the reverberation time should be brought to a value that corresponds to or exceeds the reverberation time of the bells made from bell bronze.
- the outline of the bell or bell casing shown in the figure is customary.
- Between the flange 1 and the hanger 2 of the bell slots 4 are formed in the shell 3 of the bell, which in the example shown here have a shape following the longitudinal generatrix of the bell shell and are distributed along the circumference of the bell shell at intervals from one another.
- the widths of the slots can match, but can also be different.
- the circumferential distances between the slots 4 can be the same or different.
- the slots 4 can begin at the ends of the hanger 2 on the same circumferential circle or on different circumferential circles, the lower ends also ending in the same circumferential circle or on different circumferential circles and one or more slots 4 can also protrude up to the flange 1.
- the slots 4 - in the side view of the bell casing - can be designed in an arc shape, the arc shape being curved on one or both sides, in a wavy line.
- the slots 4 - as can be seen from the figure - consist of straight lines. In the embodiment shown, a total of ten slots 4 are evenly distributed on the circumference of the bell jacket 3, the width of the webs of the bell jacket 3 between the slots 4 being greater than the slot width.
- the main advantage of the bell according to the invention is that a bell with good sound properties can be produced from aluminum or aluminum alloys.
- the material price and the time required for production are significantly reduced, which means that the production costs are also lower.
- the working time from modeling to casting is only a few days instead of a few months. Orders with a short delivery time can be accepted. Small series will also be delivered within a short time.
- the pitch can be adjusted easily and with little tuning work; coordination is quick and accurate.
- the reverberation time corresponds to that of the bells made from bell bronze, and can even be set to a higher value. Good bell sound and sound can be achieved with an aluminum or aluminum alloy bell due to the relatively small diameter and light weight gaps.
- the invention is not limited to large and heavy bells.
- the construction of the bell according to the invention results Favorable tone parameters and good economy even with small and light bells and bells.

Abstract
Description
Die Erfindung bezieht sich auf eine Glocke, die aus Aluminium oder einer Aluminiumlegierung gefertigt ist und bei der die Tonhöhe bestimmt ist und die einen langdauernden Nachhall aufweist.The invention relates to a bell which is made of aluminum or an aluminum alloy and in which the pitch is determined and which has a long-lasting reverberation.
Glocken werden seit Jahrhunderten zur Erzeugung von musikalischen Tönen, zur Signalisierung der Zeit oder zur Bekanntgabe eines Ereignisses, sowie in Orchestern, als die Melodie gliederndes Schlag- oder Punktierungsmusikinstrument verwendet. Die Glocken in ihren bekannten Formen dienen tatsächlich als idiophone Musikinstrumente.Bells have been used for centuries to produce musical tones, to signal the time or to announce an event, as well as in orchestras, as a melodic percussion or puncturing musical instrument. The bells in their familiar forms actually serve as idiophonic musical instruments.
Die Glocke kann als eine dreidimensionale Platte betrachtet werden, die auf Wirkung des Anschlags zweidimensionale Schwingungen ausführt. Im Verlauf der zweidimensionalen Schwingung gestalten sich zwei Knotenliniensysteme, und zwar das System der longitudinalen Knotenlinien und das System der kreisförmigen Knotenlinien.The bell can be viewed as a three-dimensional plate which, when struck, causes two-dimensional vibrations. Two node line systems are formed in the course of the two-dimensional oscillation, namely the system of the longitudinal node lines and the system of the circular node lines.
Das longitudinale Knotenliniensystem besteht aus sich in vertikalen Ebenen befindenden Knotenlinien, wobei die vertikalen Ebenen die vertikale Längsachse der Glocke (in deren an dem Gehänge frei herabhängender Stellung) enthalten; die Knotenlinien weisen eine den Erzeugenden des Glockenmantels annähernd gleiche Form auf. Die longitudinalen Knotenlinien unterteilen den Glockenmantel in 4 bis 12 Zonen entlang der Peripherie. Von den longitudinalen Knotenlinien weisen die Schwingungen an jener Knotenlinie die größte Amplitude auf, die von dem Schlagmittel, z. B. von dem Glockenschwengel, den Anschlag erhält.The longitudinal knot line system consists of knot lines located in vertical planes, the vertical planes containing the vertical longitudinal axis of the bell (in its freely hanging position on the hanger); the node lines have an approximately identical shape to the generatrix of the bell shell. The longitudinal node lines divide the bell mantle into 4 to 12 zones along the periphery. Of the longitudinal nodal lines, the vibrations on that nodal line have the greatest amplitude, which from the impact means, e.g. B. from the bell handle, receives the stop.
Das andere, während der Schwingung entstehende Knotenliniensystem besteht aus kreisförmigen Knotenlinien in auf der Längsachse der Glocke senkrechten Ebenen entlang der Längsachse in Abständen voneinander, wobei die Mittelpunkte der kreisförmigen Knotenlinien in der Längsachse liegen.The other node line system which arises during the vibration consists of circular node lines in planes perpendicular to the longitudinal axis of the bell along the longitudinal axis at intervals from one another, the centers of the circular node lines lying in the longitudinal axis.
An den Stellen der longitudinalen und kreisförmigen Knotenlinien führt der Glockenmantel praktisch keine Schwingungen aus. Die Schwingungsmoden der longitudinalen und kreisförmigen Knotenlinien werden frei kombiniert.At the points of the longitudinal and circular knot lines, the bell casing practically does not vibrate. The vibration modes of the longitudinal and circular node lines are freely combined.
An der Glocke findet die Schwingung mit der größten Amplitude am unteren Glockenrand, an dem Flansch statt. Der Flansch kann so betrachtet werden, als ob er der freie Rand eines eingespannten Balkens oder einer eingespannten Platte wäre. Die Schwingung, der Ton, gehen von dem Flansch aus. Praktisch führt die ganze Glocke eine Schwingungsbewegung aus, mit der Ausnahme der Einspannungsstelle, die oben in der Mitte liegt.At the bell, the vibration with the greatest amplitude takes place at the lower edge of the bell, on the flange. The flange can be viewed as if it were the free edge of a clamped beam or plate. The vibration, the sound, emanate from the flange. In practice, the whole bell oscillates, with the exception of the clamping point, which is in the middle at the top.
Der sich ergebende Ton besteht aus zwei Teilen. Als erster erscheint der Schlagton, der ein einziger kurzer Ton mit fester Tonhöhe und metallischem Klang ist. Als Glockenklang wird der Schlagklang betrachtet. Der Schlagklang hört nach kurzer Zeit auf, das Ausklingen erfolgt äußerst schnell. Der Schlagklang ist das Ergebnis einer Obertonfolge, d.h. deren subjektive Grundstimme. Dem vollkommenen Verschallen des Schlagtones vorangehend ertönt der sogenannte Glockenläutton, der mit dem ausgestafteten Schwingungszustand des Glockenmantels gekennzeichnet werden kann und den Charakter eines mehrstimmigen Klangs aufweist und recht langsam verschallt. Dieser tönende Schall besteht aus mehreren Bestandteilen, so im allgemeinen aus dem Grundton, der Terz, der Quint und der oberen Oktave, von denen der Grundton am längsten tönt; die anderen werden verhältnismäßig schnell schwächer.The resulting tone consists of two parts. The first to appear is the beat tone, which is a single short tone with a fixed pitch and metallic sound. The bell sound is considered to be the bell sound. The impact sound stops after a short time, the decay takes place extremely quickly. The beat sound is the result of an overtone sequence, i.e. their subjective basic voice. The so-called bell button that precedes the complete reverberation of the beat tone, which can be identified with the solid vibration condition of the bell casing and has the character of a polyphonic sound and sinks very slowly. This sounding sound consists of several components, generally the fundamental, the third, the fifth and the upper octave, of which the fundamental is the longest; the others weaken relatively quickly.
Die beiden Glockenklänge haben zweierlei Töne; wenn der Schlagschall weitgehend metallisch ertönt, was zahlreiche nicht-harmonische Obertöne bedeutet, ist die Tonhöhe unsicher.The two bell sounds have two tones; if the impact sound is largely metallic, which means numerous non-harmonic overtones, the pitch is uncertain.
Der tönende Schall ist weicher und leiser. Infolge des allmählichen Verschallens wird der Klang immer klarer, die Töne (Obertöne) verschallen einer nach dem andere; zuletzt ist nur noch der Grundton hörbar.The sound is softer and quieter. As a result of the gradual decay, the sound becomes clearer, the tones (overtones) decay one after the other; at last only the basic tone is audible.
Das hier geschilderte Tonbild hängt ausschließlich von der Gestaltungsform des Glokkenmantels ab; es wird weder von der Stärke des Schlags noch von der Zusammensetzung des Glockenmaterials beeinflußt, da von diesen nur die Anzahl und Stärke der Obertöne bestimmt wird.The sound image described here depends exclusively on the design of the bell shell; it is not influenced by the strength of the stroke nor by the composition of the bell material, since these only determine the number and strength of the overtones.
An eine Glocke guter Qualität wird die Forderung gestellt, daß die Tonhöhe bestimmt und die Nachhalldauer lang sind. Vom Standpunkt der Herstellung der Glocken besteht die weitere Forderung, daß die Produktion wirtschaftlich und leicht realisierbar ist, wobei hinzukommt, ob man individuelle Stücke oder Serien fertigt. Bei Glocken in der wohlbekannten Gestaltung können die erwähnten Forderungen jedoch nicht gleichzeitig erfülft werden.A bell of good quality is required to determine the pitch and the reverberation time is long. From the point of view of the manufacture of the bells, there is the further requirement that the production is economical and easy to implement, with the addition of whether one produces individual pieces or series. With bells in the well-known design, the requirements mentioned cannot be met at the same time.
Bei den bekannten Glockentypen stellt die Abstimmung des Grundtons und des Schlagtons eine schwierige Aufgabe dar. Der Hauptgrund dafür besteht darin, daß der Glockenmantel um zwei Knotenliniensysteme schwingt, wobei die beiden Knotenliniensysteme praktisch zueinander senkrecht verlaufen und auf ihre Umgebung eine gegenseitige Wirkung ausüben. Es besteht nicht die Möglichkeit, die Tonzusammensetzung im voraus bestimmen zu können.In the known bell types, matching the basic tone and the beat tone is a difficult task. The main reason for this is that the bell casing swings around two node line systems, the two node line systems being practically perpendicular to one another and having a mutual effect on their surroundings. It is not possible to determine the clay composition in advance.
Die Tonhöhe wird hauptsächlich von dem Werkstoff und dem Durchmesser der Glocke bestimmt, wobei das Gewicht der Glocke zu dem Durchmesser proportional ist. Es ist als vorteilhaft zu betrachten, wenn die vorgeschriebene bzw. gewünschte Tonhöhe mit einer Glocke mit möglichst kleinem Durchmesser und möglichst geringem Gewicht erreicht werden kann. Der kleinste Durchmesser und das geringste Gewicht können mit Gold als Werkstoff bei einer gegebenen Tonhöhe erreicht werden, mit einem größeren Durchmesser und Gewicht wird die gewünschte Tonhöhe mit Silber als Grundstoff erreicht. Infolge der hohen Preise können weder Silber, noch Gold als Grundstoffe hergenommen werden.The pitch is mainly determined by the material and the diameter of the bell, the weight of the bell being proportional to the diameter. It is considered to be advantageous if the prescribed or desired pitch can be achieved with a bell with the smallest possible diameter and the lowest possible weight. The smallest diameter and the lowest weight can be achieved with gold as the material at a given pitch, with a larger diameter and weight the desired pitch can be achieved with silver as the basic material. Due to the high prices, neither silver nor gold can be used as raw materials.
Von dem Standpunkt des erreichbaren geringen Gewichtes und eines kleinen Durchmessers können zunächst Bronze aus Cu und Sn, die sogenannte Glockenbronze, danach Messing aus Cu und Zn und eine Kupferlegierung mit Silizium (Cu + Si + Zn) bzw. siliziumhaltige Bronze in Frage kommen. Diese Grundstoffe sind noch immer sehr teuer; ihr hoher Preis kann darauf zurückgeführt werden, daß ihre Verwendung für eine Glocke die höchste Reinheit beansprucht. So werden z. B., wenn einige Hunderstel Prozent Aluminium in die Glockenbronze geraten, die Nachhallzeiten bereits auf ein Drittel verkürzt. Ein weiterer Mangel der Kupferlegierungen besteht darin, daß das Gießen der Glocke eine äußerst lange Zeit erfordert, häufig einige Monate, unabhängig davon, ob das Gewicht der Glocke mehrere Tonnen oder einige Kilo beträgt. Dabei kommt es häufig vor, daß die nach einer so langen Zeit fertig gewordene Glocke nicht den gewünschten Ton gibt.From the standpoint of the attainable gerin With a weight and a small diameter, bronze from Cu and Sn, the so-called bell bronze, then brass from Cu and Zn and a copper alloy with silicon (Cu + Si + Zn) or silicon-containing bronze can be used. These raw materials are still very expensive; their high price can be attributed to the fact that their use for a bell demands the highest purity. So z. For example, if a few hundredths of a percent aluminum gets into the bell bronze, the reverberation times are already reduced to a third. Another shortcoming of copper alloys is that it takes an extremely long time to cast the bell, often a few months, regardless of whether the bell weighs several tons or a few kilos. It often happens that the bell that has been finished after such a long time does not give the desired tone.
Man probierte Glocken aus Aluminium oder Aluminiumlegierungen herzustellen, aber bei den bekannten Glockenkonstruktionen erwiesen sich Aluminium und Aluminiumlegierungen als völlig ungeeignet, da zum Erreichen einer gegebenen Tonhöhe Glocken mit noch größerem Durchmesser und Gewicht erforderlich wären, als bei Verwendung der herkömmlichen Kupferlegierungen.One tried to produce bells from aluminum or aluminum alloys, but with the known bell constructions aluminum and aluminum alloys proved to be completely unsuitable, since bells with an even larger diameter and weight would be required to reach a given pitch than when using the conventional copper alloys.
Von dem Standpunkt einer langen Nachhalldauer ist von den Kupferlegierungen die Glockenbronze mit der Cu + Sn-Zusammensetzung die günstigste; die sonstigen Kupferlegierungen führen nicht zu dem gewünschten Resultat. Die aus Aluminium oder Aluminiumlegierungen gefertigten Glocken in der bekannten Konstruktion zeigten hinsichtlich der Nachhallzeiten unannehmbare kurze Perioden; auch der Ton war nicht angenehm.From the standpoint of a long reverberation time, the bell bronze with the Cu + Sn composition is the cheapest of the copper alloys; the other copper alloys do not lead to the desired result. The bells made of aluminum or aluminum alloys in the known construction showed unacceptably short periods in terms of reverberation times; the sound wasn't pleasant either.
Durch die Erfindung wird die Aufgabe gelöst, eine Glockenkonstruktion zu schaffen, die die Anwendung des verhältnismäßig billigen Aluminiums bzw. von Aluminiumlegierungen zu ihrer Herstellung ermöglicht und die als Erfolg Glocken, sei es als Einzelstück oder in Serie, schnell und mit einer bedeutenden Kostenverringerung herzustellen erlaubt. Eine weitere Forderung besteht darin, daß die Glocke leicht und schnell eingestimmt werden und ihre gewünschte Tonhöhe eingestellt werden kann. Desweiteren soll die Nachhallzeit auf einen Wert gebracht werden, der der Nachhallzeit der aus Glockenbronze hergestellten Glocken entspricht bzw. diesen Wert überschreitet.The invention solves the problem of creating a bell construction which enables the use of the relatively cheap aluminum or aluminum alloys for their production and which, as a success, allows the production of bells, either as a single piece or in series, quickly and with a significant reduction in costs . Another requirement is that the bell can be tuned in easily and quickly and that its desired pitch can be set. Furthermore, the reverberation time should be brought to a value that corresponds to or exceeds the reverberation time of the bells made from bell bronze.
Die Aufgabe wird erfindungsgemäß mit einer Glocke nach dem Anspruch 1 gelöst.The object is achieved with a bell according to claim 1.
Bevorzugte Ausführungsformen der erfindungsgemäßen Glocke sind in den Unteransprüchen 2 bis 6 angegeben.Preferred embodiments of the bell according to the invention are specified in subclaims 2 to 6.
Aus der DE-C-177 880 ist es zwar bekannt, am Umfang des Glockenmantels verteilte Schlitze in dem Glockenmantel auszubilden. Diese bekannte Glocke weist jedoch keinen in sich geschlossen Glockenrand auf. Vielmehr ergeben sich die Schlitze als Folge der Ausbildung hornförmiger Ansätze am unteren Glockenrand. Zweck der hohlen hornförmigen Ansätze ist es, die Lautstärke des abgestrahlten Glockenschalls zu erhöhen.From DE-C-177 880 it is known to form slots in the bell jacket distributed around the circumference of the bell jacket. However, this known bell does not have a closed bell rim. Rather, the slits result from the formation of horn-shaped projections on the lower edge of the bell. The purpose of the hollow horn-shaped approaches is to increase the volume of the bell sound emitted.
Die erfindungsgemäße Glocke wird anhand eines vorteilhaften Ausführungsbeispiels erläutert, das aus der Zeichnung in perspektivischer Darstellung ersichtlich ist.The bell according to the invention is explained using an advantageous exemplary embodiment, which can be seen in the drawing in a perspective view.
Die in der Figur dargestellte Glocke bzw. der Glockenmantel sind in ihrem Umriß in üblicher Weise gestaltet. Zwischen dem Flansch 1 und dem Gehänge 2 der Glocke sind in dem Mantel 3 der Glocke Schlitze 4 ausgebildet, die bei dem hier dargestellten Beispiel eine den longitudinalen Erzeugenden des Glockenmantels folgende Form aufweisen und entlang des Umfangs des Glokkenmantels in Abständen voneinander verteilt ausgebildet sind. Die Breiten der Schlitze können übereinstimmen, können aber auch unterschiedlich sein. Ähnlich können die Umfangsabstände zwischen den Schlitzen 4 gleich oder voneinander verschieden sein. Die Schlitze 4 können an ihren Enden zunächst dem Gehänge 2 an dem gleichen Umfangskreis oder an unterschiedlichen Umfangskreisen beginnen, wobei die unteren Enden ebenfalls bei demselben Umfangskreis oder an unterschiedlichen Umfangskreisen enden können und ein oder mehrere Schlitze 4 auch bis zum Flansch 1 ragen können. Darüberhinaus können die Schlitze 4 - in der Seitenansicht des Glockenmantels - bogenförmig gestaltet sein, wobei die Bogenform einseitig oder beidseitig, in einer Wellenlinie, gekrümmt sein kann. Desweiteren können die Schlitze 4 - wie es aus der Figur ersichtlich ist - aus geraden Strecken bestehen. Bei der gezeigten Ausführungsform sind insgesamt zehn Schlitze 4 am Umfang des Glockenmantels 3 gleichmäßig verteilt angeordnet, wobei die Breite der Stege des Glockenmantels 3 zwischen den Schlitzen 4 größer als die Schlitzbreite ist.The outline of the bell or bell casing shown in the figure is customary. Between the flange 1 and the hanger 2 of the bell slots 4 are formed in the
Der wesentliche Vorteil der erfindungsgemä- βen Glocke besteht darin, daß aus Aluminium oder Aluminiumlegierungen eine Glocke mit guten Klangeigenschaften hergestellt werden kann. Materialpreis und Zeitaufwand für die Herstellung verringern sich bedeutend, wodurch die Produktionskosten ebenfalls geringer sind. Die Arbeitszeit beträgt von der Modellierung bis zum Gießen anstatt einiger Monate nur einige Tage. So können Bestellungen mit kurzer Lieferzeit angenommen werden. Auch Kleinserien werden binnen Kurzem ausgeliefert. Die Tonhöhe kann einfach und mit geringer Abstimmungsarbeit eingestellt werden; die Abstimmung erfolgt schnell und genau. Praktisch stimmt die Nachhallzeit mit jener der aus Glockenbronze hergestellten Glocken überein, kann sogar auf einen höheren Wert eingestellt werden. Ein guter Schlagton und ein guter Schall können mit einer Glocke aus Aluminium oder einer Aluminiumlegierung aufgrund der Spalte mit verhältnismäßig kleinem Durchmesser und geringem Gewicht erreicht werden.The main advantage of the bell according to the invention is that a bell with good sound properties can be produced from aluminum or aluminum alloys. The material price and the time required for production are significantly reduced, which means that the production costs are also lower. The working time from modeling to casting is only a few days instead of a few months. Orders with a short delivery time can be accepted. Small series will also be delivered within a short time. The pitch can be adjusted easily and with little tuning work; coordination is quick and accurate. In practice, the reverberation time corresponds to that of the bells made from bell bronze, and can even be set to a higher value. Good bell sound and sound can be achieved with an aluminum or aluminum alloy bell due to the relatively small diameter and light weight gaps.
Die Erfindung beschränkt sich nicht auf großdimensionierte und schwere Glocken. Die Konstruktion der erfindungsgemäßen Glocke ergibt günstige Tonparameter und gute Wirtschaftlichkeit auch bei kleindimensionierten und leichten Glocken und Schellen.The invention is not limited to large and heavy bells. The construction of the bell according to the invention results Favorable tone parameters and good economy even with small and light bells and bells.
