Description
Die Erfindung bezieht sich auf eine Federhausvorrichtung für eine Uhr, mit einem feststehenden plattenförmigen Bauteil, das eine kreisförmige Ausnehmung aufweist, in der ein Federhaus mit seiner entsprechenden kreisförmigen Außenkontur drehbar gelagert ist, mit einem koaxial zum Federhaus drehbar gelagert angeordneten Federkem, der von einer spiralartigen Zugfeder umschlossen ist, die mit ihrem inneren Ende an dem Federkern und mit ihrem äußeren Ende mit dem Federhaus verbunden ist, wobei mit dem Federhaus ein einen Zahnkranz aufweisendes Aufzugsrad aufweisender Aufzugstrieb und mit dem Federkern ein erstes Rad eines Räderwerks der Uhr fest verbunden sind.The invention relates to a barrel device for a clock, with a fixed plate-shaped member having a circular recess in which a barrel is rotatably mounted with its corresponding circular outer contour, with a coaxially rotatably mounted to the barrel arranged Federkem, of a spiral-like Tension spring is enclosed, which is connected with its inner end to the spring core and with its outer end to the barrel, with the barrel a gear ring exhibiting elevator wheel exhibiting elevator drive and the spring core a first wheel of a train of the clock are firmly connected.
Bei einer derartigen Federhausvorrichtung ist es bekannt das ringförmige Federhaus in einer topfartigen Vertiefung des plattenförmigen Bauteils zu lagern, wobei das in die große Stufe ragende Aufzugsrad Aufzugstrieb auf der Seite der Öffnung der Vertiefung durch ein mit dem plattenförmigen Bauteil verbundenes kreisringförmiges Teil axial fixiert ist.In such a barrel device, it is known to support the annular barrel in a pot-like recess of the plate-shaped member, wherein the projecting into the large stage elevator wheel elevator drive on the side of the opening of the recess is axially fixed by an annular member connected to the plate-shaped member.
Da die Lagerung des Federhauses nur in der kleinen Stufe der Vertiefung erfolgt, ist die Lagerlänge im Verhältnis zum Durchmesser des Federhauses klein, so daß das Federhaus in der Vertiefung erheblich von seiner Sollachse abweichend kippen und verklemmen kann.Since the bearing of the barrel takes place only in the small step of the recess, the bearing length is in proportion to the diameter of the barrel small, so that the barrel can tilt and clamp in the well deviating significantly from its desired axis.
Eine von dem Federhaus unabhängige Lagerung des Federkems führt auch bei diesem zu erheblichen Abweichungen von der Sollachse, was über das mit dem Federkem verbundene erste Rad des Räderwerks die Ganggenauigkeit des Uhrwerks negativ beeinflußt.Independent of the spring suspension of the suspension spring leads also in this to significant deviations from the desired axis, which adversely affects the accuracy of the movement via the connected to the spring core first wheel of the movement.
Aus der
Aus der
Aufgabe der Erfindung ist es daher eine Federhausvorrichtung der eingangs genannten Art zu schaffen, die sich bei hoher Ganggenauigkeit des Räderwerks der Uhr durch einen geringen Bauraumbedarf auszeichnet und eine präzise Lagerung des ablaufenden Federkerns ermöglicht.The object of the invention is therefore to provide a barrel device of the type mentioned, which is at high accuracy of the Wearable the clock characterized by a small space requirement and allows precise storage of the running spring core.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die kreisförmige Ausnehmung durchgehend in dem plattenförmigen Bauteil ausgebildet ist und das Federhaus zwei sich radial über den Durchmesser der kreisförmigen Ausnehmung hinaus erstreckende Abstützbereiche aufweist, die jeweils an einer der einander gegenüberliegenden Seitenflächen des plattenförmigen Bauteils in Anlage ist.This object is achieved in that the circular recess is formed continuously in the plate-shaped member and the barrel has two radially beyond the diameter of the circular recess extending support portions, which is in each case at one of the opposite side surfaces of the plate-shaped component in abutment.
Durch diese Ausbildung wird ein großer Teil der Dicke des plattenförmigen Bauteils als Lagerlänge genutzt und zusammen mit den an den einander gegenüberliegenden Seitenflächen des plattenförmigen Bauteils anliegenden Abstützbereichen eine weitgehend spielarme und kippfreie Lagerung des Federhauses bei gleichzeitig geringer Bauhöhe erreicht.By this design, a large part of the thickness of the plate-shaped member is used as a bearing length and achieved together with the voltage applied to the opposite side surfaces of the plate-shaped component support areas a largely low-backlash and tilt-free storage of the barrel at the same time low height.
Zur einfachen Montage kann zumindest ein Abstützbereich insbesondere durch eine Schraubverbindung lösbar mit dem Federhaus verbunden sein.For ease of assembly, at least one support region can be detachably connected to the barrel, in particular by a screw connection.
Eine stabile Ausgestaltung mit ausreichend großen Schrauben wird dabei dadurch ermöglicht, daß das Federhaus topfartig mit einem Boden ausgebildet ist, mit dem der eine Abstützbereich durch Schrauben verbunden ist.A stable configuration with sufficiently large screws is thereby made possible that the barrel is pot-shaped with a bottom, with which a support area is connected by screws.
Der Boden und der mit diesem Boden verbundene Abstützbereich können koaxiale Durchgangsbohrungen aufweisen, durch die der Federkem aus dem Federhaus herausragt.The floor and the support area connected to this floor can have coaxial through holes through which the spring core protrudes from the barrel.
Zur exakt koaxialen Positionierung und zusätzlich formschlüssigen Verbindung kann der Boden einen koaxial zur Außenseite hervorstehenden zylindrischen Zentrieransatz besitzen, auf den ein scheibenartig ausgebildeter Abstützbereich mit einer entsprechenden Bohrung aufsetzbar ist.For exactly coaxial positioning and additionally positive connection, the bottom can have a coaxial with the outside protruding cylindrical centering approach, on which a disc-like trained support area with a corresponding hole can be placed.
Damit die Drehachsen von Federkem und Federhaus mit hoher Genauigkeit übereinstimmen, kann der Boden eine koaxiale Lagerbohrung aufweisen, in der ein Ende des Federkems drehbar gelagert oder in die ein Lager zur drehbaren Lagerung eines Endes des Federkems eingesetzt ist, wodurch auch die Ganggenauigkeit des Uhrwerks erhöht wird.In order that the axes of rotation of the spring core and barrel match with high accuracy, the bottom may have a coaxial bearing bore in which one end of the spring core is rotatably mounted or in which a bearing for rotatably supporting one end of the spring core is inserted, thereby also increasing the accuracy of the movement becomes.
Es ist aber auch möglich, daß ein Ende des Federkems in einem Lager drehbar gelagert ist, das in einer zum plattenförmigen Bauteil parallelen Brücke angeordnet ist.But it is also possible that one end of the spring core is rotatably mounted in a bearing which is arranged in a direction parallel to the plate-shaped member bridge.
Trägt das aus dem Federhaus herausragende Ende des Federkems ein Getrieberad einer Zusatzeinrichtung so ergeben sich vielfältige Anordnungsmöglichkeiten nicht nur von Lagerungen der des Federkems sondem auch zum Anschluß von Zusatzfunktionen.Carries the protruding from the barrel end of the Federkems a gear of an accessory so arise diverse arrangement options not only by bearings of the spring core sondem also for connecting additional functions.
Dazu kann das aus dem Federhaus herausragende Ende des Federkems ein Getrieberad einer Zusatzeinrichtung tragen wobei das Getrieberad ein Getrieberad eines Stellungsgetriebes zur Begrenzung der Umlaufzahl oder ein Getrieberad eines Getriebes zur Anzeige einer Gangreserve sein kann.For this purpose, the protruding from the barrel end of the Federkems carry a gear of an accessory device wherein the gear can be a gear of a position gear to limit the circulation number or a gear of a transmission to display a power reserve.
Damit kann die Zusatzeinrichtung außerhalb des Federhauses auf der Oberseite des als Aufzugsrad ausgebildeten Abstützbereichs angeordnet und z. B für Einstellvorgänge gut zugänglich sein.Thus, the additional device outside the barrel arranged on the top of the trained as a lift wheel support area and z. B be easily accessible for setting operations.
Ein Ende des Federkems kann in einem Lager drehbar gelagert sein, das an einer feststehenden Werkplatte angeordnet ist, die sich in einem derartigen Abstand zum plattenförmigen Bauteil befindet, daß ein relativ großer Lagerabstand der Lager des Federkems erreichbar ist. Dies trägt zu einer exakten Lagerung des ersten Rades des Räderwerks der Uhr und damit auch zu einer hohen Ganggenauigkeit des Uhrwerks bei.One end of the spring core can be rotatably mounted in a bearing which is arranged on a fixed work plate which is located at such a distance from the plate-shaped component, that a relatively large bearing distance of the bearing of the spring core can be achieved. This contributes to an exact storage of the first wheel of the gear train of the clock and thus also to a high accuracy of the movement.
In Doppelfunktion und damit bauraumsparend kann einer der Abstützbereiche als Aufzugsrad ausgebildet sein.In a double function and thus save space, one of the support areas can be designed as a lift wheel.
Dabei kann das Aufzugsrad auch ein Sperrad sein.The elevator wheel can also be a ratchet wheel.
Eine nur wenige Bauteile benötigende Ausbildung wird dadurch erreicht, daß das Federhaus mit dem Zahnkranz des Aufzugsrades versehen ist.A few components requiring training is achieved in that the barrel is provided with the ring gear of the elevator wheel.
Zumindest einer der Abstützbereiche kann ringartig ausgebildet sein.At least one of the support areas may be formed like a ring.
Ebenfalls ein nur wenige Bauteile benötigender Aufbau wird erreicht, wenn einer der Abstützbereiche einteilig mit dem Federhaus ausgebildet ist.Likewise, a structure requiring only a few components is achieved if one of the support regions is formed integrally with the barrel.
Weist das plattenförmige Bauteil eine die kreisförmige Ausnehmung umgebende stufenartige Ausnehmung auf, in der einer der Abstützbereiche angeordnet ist, der axial an dem Boden der stufenförmigen Ausnehmung abgestützt ist, so wird eine geringe Bauhöhe erreicht.If the plate-shaped component has a step-like recess surrounding the circular recess, in which one of the support regions is arranged, which is supported axially on the bottom of the step-shaped recess, a small overall height is achieved.
Weist der Boden der stufenförmigen Ausnehmung einen axial hervorstehenden Ringansatz auf, an dem der Abstützbereich abgestützt ist, so sind die Reibungswiderstände beim Drehen des ersten Federhause aufgrund der geringen Anlagefläche des einen Abstützbereichs an dem Boden der stufenförmigen Ausnehmung niedrig.If the bottom of the step-shaped recess has an axially protruding annular projection on which the support region is supported, the frictional resistances during rotation of the first spring housing are low due to the small contact surface of the one support region at the bottom of the stepped recess.
Das feststehende plattenförmige Bauteil kann in Doppelfunktion eine Räderbrücke sein.The fixed plate-shaped component can be a double bridge wheel bridge.
Vorzugsweise ist das erste Rad des Uhrwerks ein Antriebsrad.Preferably, the first wheel of the movement is a drive wheel.
Zum Erhöhen der Gangdauer der Uhr bei gleichzeitig geringem Platzbedarf für die Federhausvorrichtung ist koaxial zu dem Federhaus ein weiteres Federhaus angeordnet ist und der Federkem durchragt beide Federhäuser, wobei der Federkem aus einer Federwelle und einer auf der Federwelle drehbar gelagerten Federhülse besteht, mit der die Zugfeder mit ihrem inneren Ende verbunden ist sowie mit einer weiteren den Federkem umschließenden spiralartigen Zugfeder, die mit ihrem inneren Ende mit der Federhülse und mit ihrem äußeren Ende mit dem weiteren Federhaus verbunden ist und wobei mit der Federwelle und dem weiteren Federhaus das erste Rad des Uhrwerks fest verbunden ist.To increase the gear duration of the clock while requiring little space for the barrel device coaxial with the barrel another barrel is arranged and the spring core extends through both barrels, wherein the spring core consists of a spring shaft and a spring sleeve rotatably mounted on the spring sleeve, with which the tension spring is connected to its inner end and with another spring core enclosing spiral-like tension spring with its inner end with the spring sleeve and with its outer end with is connected to the other barrel and wherein the first wheel of the movement is firmly connected to the spring shaft and the other barrel.
Dabei tritt zwischen den die Feder verbindenden Gliedern nur wenig die Ganggenauigkeit beeinflussende Reibung auf.It occurs between the spring connecting members only slightly affecting the accuracy accuracy friction.
Nur wenige Bauteile sind erforderlich, wenn das weitere Federhaus topfartig mit einem Boden ausgebildet ist, mit dem die Federwelle fest verbunden ist.Only a few components are required if the other barrel is pot-shaped with a bottom to which the spring shaft is firmly connected.
Dabei wird eine hohe Koaxialität von weiterem Federhaus und Federwelle erreicht, wenn der Boden eine koaxiale, von der Federwelle durchragte Öffnung besitzt.In this case, a high coaxiality of further barrel and spring shaft is achieved when the bottom has a coaxial, projected by the spring shaft opening.
Zu einer weiteren Reduzierung der zu montierenden Bauteile führt es, wenn das weitere Federhaus einteilig mit dem ersten Rad des Uhrwerks ausgebildet ist.It leads to a further reduction of the components to be assembled when the further barrel is formed integrally with the first wheel of the movement.
Zur Sicherung der Zugfedern in ihren Federhäusern kann zumindest eine der koaxialen Öffnungen des Federhauses und/oder des weiteren Federhauses von einem Federhausdeckel verschlossen sein, der eine Koaxialöffnung besitzt, durch die der Federkem hindurchragt.To secure the tension springs in their barrels, at least one of the coaxial openings of the barrel and / or the other barrel can be closed by a barrel cover, which has a coaxial opening through which the spring core protrudes.
Ein oder mehrere Lager des Federkems können als Steinlager ausgebildet sein.One or more bearings of the spring core may be formed as a stone bearing.
