Aus der
Die Erfindung schlägt eine tragbare Werkzeugmaschine vor mit den Merkmalen des Anspruchs 1.The invention proposes a portable machine tool with the features of claim 1.
Es wird eine tragbare Werkzeugmaschine, insbesondere eine Handwerkzeugmaschine, mit zumindest einer Spindel zur Aufnahme und zum Antrieb eines Bearbeitungswerkzeugs, mit zumindest einer Bremseinheit, die dazu vorgesehen ist, zumindest in einem Bremsmodus die Spindel und/oder das Bearbeitungswerkzeug abzubremsen, und mit zumindest einer Ablaufsicherungseinheit, die zumindest im Bremsmodus dazu vorgesehen ist, ein Ablaufen des Bearbeitungswerkzeugs von der Spindel zu vermeiden, vorgeschlagen. Unter einer "tragbaren Werkzeugmaschine" soll hier insbesondere eine Werkzeugmaschine, insbesondere eine Handwerkzeugmaschine, verstanden werden, die von einem Bediener transportmaschinenlos transportiert werden kann. Die tragbare Werkzeugmaschine weist insbesondere eine Masse auf, die kleiner ist als 50 kg, bevorzugt kleiner als 20 kg und besonders bevorzugt kleiner als 10 kg. Unter einer "Bremseinheit" soll hier insbesondere eine Einheit verstanden werden, die dazu vorgesehen ist, eine Geschwindigkeit, insbesondere eine Umlaufgeschwindigkeit, eines sich bewegenden Bauteils, insbesondere eines sich drehenden Bauteils, im Vergleich zu einer Arbeitsgeschwindigkeit des Bauteils zumindest im Wesentlichen zu verringern und/oder zu begrenzen. Bevorzugt verringert und/oder begrenzt die Bremseinheit die Geschwindigkeit zusätzlich zu einem rein reibungsbedingten Verringern und/oder Begrenzen der Geschwindigkeit infolge einer Lagerung des Bauteils. Unter einem "Bremsmodus" soll hier insbesondere ein Modus der tragbaren Werkzeugmaschine, insbesondere der Handwerkzeugmaschine, verstanden werden, in dem die Spindel mittels der Bremseinheit abgebremst wird, so dass ein Nachlaufen der Spindel, wie beispielsweise bei einer Unterbrechung einer Stromzufuhr zu einem Elektromotor, vorteilhaft zumindest weitgehend verhindert werden kann. Bei dem Bremsmodus kann es durch Massenträgheitsmomente des Bearbeitungswerkzeugs, insbesondere eines scheibenförmigen Bearbeitungswerkzeugs, zu einer Relativbewegung zwischen dem auf der Spindel befestigten Bearbeitungswerkzeug, der Ablaufsicherungseinheit und einer zum Festspannen des Bearbeitungswerkzeugs auf der Spindel vorgesehenen Spannmutter kommen. Die Relativbewegung zwischen dem Bearbeitungswerkzeug und der Spannmutter kann dazu führen, dass die Spannmutter gelöst wird und somit von der Spindel ablaufen kann.It is a portable machine tool, in particular a hand tool, with at least one spindle for receiving and driving a machining tool, with at least one brake unit, which is intended to brake at least in a braking mode, the spindle and / or the machining tool, and with at least one flow assurance unit , which is provided at least in the braking mode to avoid running of the machining tool from the spindle proposed. A "portable machine tool" is to be understood here in particular as meaning a machine tool, in particular a hand tool machine, which can be transported without transport machine by an operator. In particular, the portable power tool has a mass which is less than 50 kg, preferably less than 20 kg and particularly preferably less than 10 kg. A "braking unit" is to be understood here as meaning, in particular, a unit which is intended to at least substantially reduce a speed, in particular a rotational speed, of a moving component, in particular of a rotating component, compared to an operating speed of the component, and / or or limit. Preferably, the braking unit reduces and / or limits the speed in addition to a purely friction-related Reducing and / or limiting the speed due to storage of the component. A "braking mode" is to be understood here as meaning, in particular, a mode of the portable power tool, in which the spindle is braked by means of the braking unit, so that tracking of the spindle, such as, for example, when a power supply to an electric motor is interrupted, is advantageous at least largely prevented. In the braking mode, moments of inertia of the machining tool, in particular of a disc-shaped machining tool, may result in relative movement between the machining tool mounted on the spindle, the run-down safety unit and a clamping nut provided on the spindle for clamping the machining tool. The relative movement between the machining tool and the clamping nut can cause the clamping nut is released and thus can run off the spindle.
Unter einer "Ablaufsicherungseinheit" soll hier insbesondere eine Einheit verstanden werden, die dazu vorgesehen ist, ein Aufheben einer Spannkraft zum Festspannen des Bearbeitungswerkzeugs in einer Axialrichtung in einem Bremsmodus zumindest im Wesentlichen zu verhindern und insbesondere dazu vorgesehen ist, eine in einem montierten Zustand auf das Bearbeitungswerkzeug wirkende Spannkraft zu erhöhen. Unter einer "Axialrichtung" soll hier insbesondere eine Richtung verstanden werden, die zumindest im Wesentlichen parallel zu einer Rotationsachse der Spindel verläuft. Unter "im Wesentlichen parallel" soll hier insbesondere eine Ausrichtung einer Richtung relativ zu einer Bezugsrichtung, insbesondere in einer Ebene, verstanden werden, wobei die Richtung gegenüber der Bezugsrichtung eine Abweichung insbesondere kleiner als 8°, vorteilhaft kleiner als 5° und besonders vorteilhaft kleiner als 2° aufweist. Bevorzugt ist die Ablaufsicherungseinheit abnehmbar mit der Spindel gekoppelt. Unter "abnehmbar" soll hier insbesondere eine Entkopplung der Ablaufsicherungseinheit von der Spindel verstanden werden, wobei zumindest eine Funktion der Ablaufsicherungseinheit, insbesondere eine Relativbewegung zwischen zumindest zwei Ablaufsicherungselementen der Ablaufsicherungseinheit, in einem entkoppelten Zustand erhalten bleibt. Besonders bevorzugt ist die Ablaufsicherungseinheit als Aufnahmeflansch ausgebildet. Es ist jedoch auch denkbar, dass die Ablaufsicherungseinheit als Spannmutter ausgebildet ist. Mittels der erfindungsgemäßen Ausgestaltung kann vorteilhaft eine hohe Betriebssicherheit der tragbaren Werkzeugmaschine erreicht werden. Es kann ferner vorteilhaft mittels der erfindungsgemäßen Ablaufsicherungseinheit ein Ablaufen der Spannmutter von der Spindel und somit ein Lösen des Bearbeitungswerkzeugs von der Spindel vermieden werden.A "flow safety unit" is to be understood here as meaning, in particular, a unit which is intended to at least substantially prevent a release of a clamping force for clamping the machining tool in an axial direction in a braking mode and is intended, in particular, to mount one in an assembled state on the Machining tool to increase acting clamping force. An "axial direction" is to be understood here in particular as meaning a direction which runs at least substantially parallel to an axis of rotation of the spindle. "Substantially parallel" is to be understood here as meaning, in particular, an alignment of a direction relative to a reference direction, in particular in a plane, wherein the direction relative to the reference direction is a deviation, in particular less than 8 °, advantageously less than 5 ° and particularly advantageously less than 2 °. Preferably, the process control unit is detachably coupled to the spindle. "Detachable" is to be understood here in particular as a decoupling of the operational safety device from the spindle, wherein at least one function of the safety device, in particular a relative movement between at least two safety elements of the safety device, remains in a decoupled state. Particularly preferably, the flow safety unit is designed as a receiving flange. However, it is also conceivable that the flow assurance unit is designed as a clamping nut. By means of the embodiment according to the invention can advantageously be achieved high reliability of the portable power tool. It can also be advantageous by means of the flow control unit according to the invention a running of the clamping nut of the spindle and thus a release of the machining tool can be avoided by the spindle.
Des Weiteren wird vorgeschlagen, dass die tragbare Werkzeugmaschine eine Codierungseinheit umfasst, die dazu vorgesehen ist, eine Codierung zumindest zwischen der Spindel und der Ablaufsicherungseinheit zu erzeugen. Unter einer "Codierungseinheit" soll hier insbesondere eine Einheit verstanden werden, die dazu vorgesehen ist, eine Schnittstelle der tragbaren Werkzeugmaschine zwischen zumindest zwei Bauteilen, insbesondere zwischen der Spindel und der Ablaufsicherungseinheit, zu verschlüsseln, insbesondere gemäß einem Schlüssel-Schlüsselloch-Prinzip. Die Schnittstelle zwischen der Spindel und der Ablaufsicherungseinheit ist insbesondere dazu vorgesehen, eine axiale Position der Ablaufsicherungseinheit, bezogen auf eine Abmessung der Spindel entlang der Axialrichtung, an der Spindel festzulegen und eine konzentrische Position der Ablaufsicherungseinheit, bezogen auf eine Rotationsachse der Spindel, festzulegen. Des Weiteren ist die Schnittstelle zwischen der Spindel und der Ablaufsicherungseinheit insbesondere dazu vorgesehen, Kräfte und/oder Drehmomente von der Spindel auf die Ablaufsicherungseinheit zu übertragen. Bevorzugt ist die Codierungseinheit dazu vorgesehen, eine Montierbarkeit von Bauteilen zu ermöglichen, die eine mit der verschlüsselten Schnittstelle korrespondierende Ausgestaltung, insbesondere eine Ausgestaltung zur Entschlüsselung der verschlüsselten Schnittstelle, aufweisen. Ferner ist die Codierungseinheit bevorzugt dazu vorgesehen, eine Montierbarkeit von Bauteilen zu verhindern, die eine von der verschlüsselten Schnittstelle abweichende Ausgestaltung, insbesondere eine zur Entschlüsselung der verschlüsselten Schnittstelle ungeeignete Ausgestaltung, aufweisen. Unter einem "Bauteil, das eine von der verschlüsselten Schnittstelle abweichende Ausgestaltung aufweist" soll hier insbesondere ein Bauteil verstanden werden, das zumindest im Wesentlichen eine mit der Spindel korrespondierende Dimensionierung, insbesondere bezüglich einer Aufnahmeöffnung zur Aufnahme der Spindel und/oder einer Gewindegröße, aufweist und das entkoppelt von einem mit der Codierungseinheit korrspondierenden Element ausgebildet ist. Die Codierungseinheit kann ferner dazu vorgesehen sein, ein Antriebsmoment zum Antrieb der Spindel zu unterbinden, bis eine Ablaufsicherungseinheit mit einem zur Enschlüsselung der verschlüsselten Schnittstelle ausgebildeten Codierungselement an der Spindel montiert ist. Hierbei kann die Codierungseinheit beispielsweise dazu vorgesehen sein, eine mechanische Blockierung der Spindel zu erzeugen, bis die Ablaufsicherungseinheit mit einem zur Enschlüsselung der verschlüsselten Schnittstelle ausgebildeten Codierungselement an der Spindel montiert ist. Eine Montage an der mittels der Bremseinheit abbremsbaren Spindel eines Bauteils, das eine von der verschlüsselten Schnittstelle abweichende Ausgestaltung aufweist, insbesondere eine von einer Ablaufsicherungseinheit entkoppelte Aufnahmeeinheit, kann vorteilhaft verhindert werden.Furthermore, it is proposed that the portable power tool comprises an encoding unit which is provided to generate an encoding at least between the spindle and the operation safety unit. A "coding unit" is to be understood here as meaning, in particular, a unit which is intended to encrypt an interface of the portable power tool between at least two components, in particular between the spindle and the execution assurance unit, in particular according to a key-keyhole principle. The interface between the spindle and the anti-drainage unit is in particular intended to fix an axial position of the anti-skid unit relative to a dimension of the spindle along the axial direction on the spindle and to define a concentric position of the anti-skid unit with respect to an axis of rotation of the spindle. Furthermore, the interface between the spindle and the safety device is provided in particular for transmitting forces and / or torques from the spindle to the safety device. Preferably, the coding unit is provided to allow mountability of components that have a configuration corresponding to the encrypted interface, in particular a configuration for decrypting the encrypted interface. Furthermore, the coding unit is preferably provided to prevent a mountability of components which have a configuration deviating from the encrypted interface, in particular an embodiment which is unsuitable for decrypting the encrypted interface. A "component having an embodiment deviating from the encrypted interface" is to be understood here as meaning, in particular, a component which has at least essentially a dimensioning corresponding to the spindle, in particular with respect to a receiving opening for receiving the spindle and / or a thread size, and which is decoupled from an element which corrupts with the coding unit. The coding unit may also be provided to prevent a drive torque for driving the spindle until a flow assurance unit is mounted with a trained for encoding the encrypted interface coding element to the spindle. In this case, the coding unit can be provided, for example, to generate a mechanical blocking of the spindle until the sequence assurance unit has a coding element designed to decrypt the encrypted interface at the Spindle is mounted. An assembly on the braked by the brake unit spindle of a component having a deviating from the encrypted interface configuration, in particular a decoupled from a flow control unit receiving unit, can be advantageously prevented.
Des Weiteren wird vorgeschlagen, dass die Codierungseinheit als elektronische, elektrische, optische, magnetische und/oder elektromagnetische Codierungseinheit ausgebildet ist. Die Codierungseinheit ist hierbei bevorzugt mit einer Steuer- und/oder Regeleinheit gekoppelt, die ein Anlaufen einer Elektromotoreinheit einer Antriebseinheit der tragbaren Werkzeugmaschine steuert und/oder regelt. Unter einer "Steuer- und/oder Regeleinheit" soll hier insbesondere eine Einheit mit zumindest einem Steuergerät verstanden werden. Unter einem "Steuergerät" soll insbesondere eine Einheit mit einer Prozessoreinheit und mit einer Speichereinheit sowie mit einem in der Speichereinheit gespeicherten Betriebsprogramm verstanden werden. Es kann vorteilhaft eine Codierungseinheit erreicht werden, die beispielweise einem Bediener mittels zumindest einer Anzeigeeinheit eine Montage einer Aufnahmeeinheit, die eine von der verschlüsselten Schnittstelle abweichende und/oder ungeeignete Ausgestaltung aufweist, anzeigen kann. Ferner kann vorteilhaft ein Anlaufen der Elektromotoreinheit der Antriebseinheit bei einer montierten Aufnahmeeinheit, die eine von der verschlüsselten Schnittstelle abweichende und/oder ungeeignete Ausgestaltung aufweist, verhindert werden.Furthermore, it is proposed that the coding unit is designed as an electronic, electrical, optical, magnetic and / or electromagnetic coding unit. The coding unit is in this case preferably coupled to a control and / or regulating unit which controls and / or regulates the starting of an electric motor unit of a drive unit of the portable power tool. A "control and / or regulating unit" is to be understood here in particular as a unit having at least one control unit. A "control unit" is to be understood in particular as meaning a unit having a processor unit and a memory unit as well as an operating program stored in the memory unit. It can be achieved advantageously a coding unit, for example, an operator by means of at least one display unit, a mounting of a recording unit, which has a deviating from the encrypted interface and / or inappropriate configuration can display. Furthermore, a tarnishing of the electric motor unit of the drive unit can advantageously be prevented in the case of a mounted receiving unit which has a deviating from the encrypted interface and / or inappropriate configuration.
Vorzugsweise weist die elektronische Codierungseinheit zumindest ein RFID-Codierungselement auf, das an der Ablaufsicherungseinheit angeordnet ist. Das RFID-Codierungselement ist insbesondere als RFID-Transponderausgebildet. Bevorzugt weist die tragbare Werkzeugmaschine ein RFID-Lesegerät auf, das dazu vorgesehen ist, einen Schlüssel und/oder eine Kennung des RFID-Transponders auszulesen.

Die Abtriebseinheit 62a des Winkelschleifers 44a umfasst ein Abtriebselement 74a, an dem zumindest ein als erster Permanentmagnet 76a ausgebildetes Bremselement 78a der Bremseinheit 16a angeordnet ist. Die Abtriebseinheit 62a ist als Winkelgetriebe 80a ausgebildet, das zur Drehmomentübertragung mit der Antriebseinheit 58a des Winkelschleifers 44a gekoppelt ist. Die Bremseinheit 16a ist entlang eines von der Antriebseinheit 58a ausgehenden Kraftflusses hinter einem Getriebeeingangszahnrad 82a des Winkelgetriebes 80a angeordnet. Das Abtriebselement 74a ist hierbei als Tellerrad 84a ausgebildet. Das Tellerrad 84a ist in einem montierten Zustand der Abtriebseinheit 62a im Eingriff mit einem Ritzel 86a der Antriebseinheit 58a. Das Getriebeeingangszahnrad 82a wird somit von dem Tellerrad 84a gebildet.The
Die Abtriebseinheit 62a umfasst ferner die drehbar gelagerte Spindel 12a, einen Lagerflansch 88a, ein im Lagerflansch 88a angeordnetes Lagerelement 90a und ein drehfest mit der Spindel 12a gekoppeltes Abtriebselement 92a, das als Mitnahmeelement 94a ausgebildet ist. Das Tellerrad 84a ist mittels einer Spielpassung auf der Spindel 12a angeordnet. Der Lagerflansch 88a ist mittels Befestigungselementen (hier nicht näher dargestellt) der Abtriebseinheit 62a lösbar mit dem Getriebegehäuse 60a verbunden. Ferner kann das Bearbeitungswerkzeug 14a mittels eines Spannelements (hier nicht näher dargestellt) zur Bearbeitung eines Werkstücks drehfest mit der Spindel 12a verbunden werden. Das Bearbeitungswerkzeug 14a kann somit in einem Betrieb des Winkelschleifers 44a rotierend angetrieben werden.The
Der mit dem Tellerrad 84a drehfest verbundene erste Permanentmagnet 76a ist kreisringförmig ausgebildet (
Des Weiteren weist die Bremseinheit 16a ein weiteres Bremselement 126a auf, das als Wirbelstromelement 128a ausgebildet ist. Somit ist die Bremseinheit 16a als Wirbelstrombremse ausgebildet. Es ist jedoch auch denkbar, dass die Bremseinehit 16a alternativ zum Wirbelstromelement 128a ein als Hystereseelement ausgebildetes Bremselement aufweist und somit als Hysteresebremse ausgebildet ist. Das Wirbelstromelement 128a ist aus einem elektrisch leitfähigen Material gebildet, wie beispielsweise Aluminium und/oder Kupfer. Ferner ist das Wirbelstromelement 128a entlang der Rotationsachse 108a des Tellerrads 84a axial zwischen dem ersten Permanentmagnet 76a und dem zweiten Permanentmagnet 120a angeordnet. Das Wirbelstromelement 128a ist fest mit dem Lagerflansch 88a verbunden. Somit werden der erste Permanentmagnet 76a und der zweite Permanentmagnet 120a in einem Betrieb des Winkelschleifers 44a mittels der Spindel 12a relativ zum Wirbelstromelement 128a bewegt. Zur Vermeidung eines magnetischen Kurzschlusses sind das Mitnahmeelement 94a und die Spindel 12a aus einem unmagnetisierbaren Material ausgebildet, wie beispielsweise Edelstahl usw.Furthermore, the
Die Bremseinheit 16a ist in einem Ruhezustand des Winkelschleifers 44a in einem Bremsmodus. Im Bremsmodus stehen sich jeweils entgegengesetzt gerichtete Polaritäten der Winkelsegmente 116a, 118a des ersten Permanentmagnets 76a und der Winkelsegmente des zweiten Permanentmagnets 120a, entlang der Rotationsachse 108 des Tellerrads 84a betrachtet, gegenüber. Bei einer Inbetriebnahme des Winkelschleifers 44a durch eine Bestromung einer Elektromotoreinheit der Antriebseinheit 58a wird das Tellerrad 84a durch das Ritzel 86a angetrieben. Hierbei wird das Tellerrad 84a relativ zum Mitnahmeelement 94a um die Rotationsachse 108a verdreht, bis die Drehmitnahmeelemente 100a, 102a, 104a an Randbereichen der Drehmitnahmeausnehmungen 110a, 112a, 114a anliegen. Hierdurch wird das Tellerrad 84a drehfest mit der Spindel 12a gekoppelt. Die Spindel 12a wird infolgedessen rotierend angetrieben. Das an der Spindel 12a befestigte Bearbeitungswerkzeug 14a wird somit ebenfalls rotierend angetrieben. In einem Betrieb des Winkelschleifers 44a wirken geringe magnetische Kräfte auf das Wirbelstromelement 128a ein. Zur Verringerung der magnetischen Kräfte ist es auch denkbar, dass die Permanentmagnete 76a, 120a zusätzlich zur Verdrehung relativ zueinander mittels der Aktivierungseinheit 72a entlang der Rotationsachse 108a translatorisch relativ zueinander bewegt werden. Hierbei kann eine Distanz zwischen den Permanentmagneten 76a, 120a verändert werden. Es kann beispielsweise eine Nut an der Spindel 12a vorgesehen sein, die entlang der Rotationsachse 108a eine mathematisch definierte Steigung aufweist. In die Nut könnte beispielsweise ein Hubelement eingreifen. Infolge einer Relativbewegung um die Rotationsachse 108a des Tellerrads 84a könnte der erste Permanentmagnet 76a in eine vom Mitnahmeelement 94a weggerichtete Richtung relativ zum zweiten Permanentmagnet 120a bewegt werden.The
Der erste Permanentmagnet 76a wird infolge der Relativbewegung zwischen dem Tellerrad 84a und dem Mitnahmeelement 94a relativ zum zweiten Permanentmagnet 120a verdreht. Hierdurch wird die Bremseinheit 16a in einen Betriebsmodus geschaltet, in dem geringe magnetische Kräfte der Bremseinheit 16a auf das Wirbelstromelement 128a einwirken. Die Aktivierungseinheit 72a ändert bei einem Übergang von einem Bremsmodus in einen Betriebsmodus eine Polstellung des ersten Permanentmagnets 76a relativ zu dem zweiten Permanentmagnet 120a der Bremseinheit 16a. Im Betriebsmodus stehen sich somit jeweils gleich gerichtete Polaritäten der Winkelsegmente 116a, 118a des ersten Permanentmagnets 76a und der Winkelsegmente des zweiten Permanentmagnets 120a, entlang der Rotationsachse 108a des Tellerrads 84a betrachtet, gegenüber.The first
Bei einem Ausschalten des Winkelschleifers 44a wird das Ritzel 86a durch die Elektromotoreinheit abgebremst. Das auf der Spindel 12a befestigte Bearbeitungswerkzeug 14a dreht sich infolge einer Massenträgheit weiter. Die Spindel 12a wird somit ebenfalls weiter um die Rotationsachse 108a gedreht. Das Bearbeitungswerkzeug 14a weist im Vergleich zum Ritzel 86a größere Massenträgheitsmomente auf. Das Ritzel 86a bremst somit das Tellerrad 84a ab. Das Tellerrad 84a wird relativ zum Mitnahmeelement 94a um die Rotationsachse 108a verdreht, bis die Drehmitnahmeelemente 100a, 102a, 104a an Randbereichen der Drehmitnahmeausnehmungen 110a, 112a, 114a anliegen. Die Bremseinheit 16a wird hierbei in einen Bremsmodus geschaltet. Die zwei Permanentmagnete 76a, 120a werden relativ zueinander verdreht. Der erste Permanentmagnet 76a wird hierbei relativ zum zweiten Permanentmagnet 120a verdreht, bis sich jeweils entgegengesetzt gerichtete Polaritäten der Winkelsegmente 116a, 118a des ersten Permanentmagnet 76a und der Winkelsegmente des zweiten Permanentmagnets 120a, entlang der Rotationsachse 108a des Tellerrads 84a betrachtet, gegenüberstehen. Hierdurch wird im Wirbelstromelement 128a eine Spannung induziert. Die induzierte Spannung bewirkt einen Stromfluss senkrecht und wirbelförmig zu einem magnetischen Fluss der Bremseinheit 16a. Hierbei werden Wirbelströme gebildet. Die Wirbelströme erzeugen in dem Wirbelstromelement 128a ein magnetisches Feld, das einem magnetischen Feld der Permanentmagnete 76a, 120a entgegenwirkt. Hierdurch wird ein Bremsmoment erzeugt, das die sich mit der Spindel 12a relativ zum Wirbelstromelement 128a drehenden Permanentmagnete 76a, 120a abbremst. Somit werden die Spindel 12a und das Bearbeitungswerkzeug 14a ebenfalls abgebremst. Eine Stärke des magnetischen Felds der Bremseinheit 16a und somit eine Ausbreitung eines magnetischen Flusses der Bremseinheit 16a zur Erzeugung des Bremsmoments ist abhängig von einer Distanz entlang der Rotationsachse 108a zwischen dem ersten Permanentmagnet 76a und dem zweiten Permanentmagnet 120a und von einer Polstellung entlang der Umfangsrichtung 106a des ersten Permanentmagnets 76a und des zweiten Permanentmagnets 120a relativ zueinander.When the
Des Weiteren ist die Bremseinheit 16a zusammen mit der Abtriebseinheit 62a als Montagemodul 40a ausgebildet (
In einer alternativen Ausführung der als Winkelschleifer 44a ausgebildeten tragbaren Werkzeugmaschine 10a ist es denkbar, dass die Werkzeugmaschien 10a zusätzlich zur Bremseinheit 16a eine weitere Bremseinheit aufweist, die in dem Motorgehäuse 56a des Winkelschleifers 44a angeordnet ist. Ferner ist es denkbar, dass der Winkelschleifer 44a eine Kühleinheit umfasst, die dazu vorgesehen ist, von der Bremseinheit 16a im Bremsmodus infolge einer inneren Reibung des Wirbelstromelements 128a erzeugte Wärme abzuführen. Ferner ist es denkbar, dass die Bremseinheit 16a einen Elektromagnet aufweist. Der Elektromagnet kann dazu vorgesehen sein, während eines Anlaufens der Antriebseinheit 58a ein zusätzliches Drehmoment zur Erreichung einer Arbeitsdrehzahl der Elektromotoreinheit in einer kurzen Zeitspanne zu ermöglichen, wie vorzugsweise zur Erreichung eines Boostbetriebs. Es ist jedoch auch denkbar, dass der Elektromagnet dazu vorgesehen ist, ein magnetisches Feld der Permanentmagnete 76a, 120a zu verstärken. Hierdurch kann ein starkes Bremsmoment zum Abbremsen der sich drehenden Permanentmagente 76a, 120a erreicht werden. Der Elektromagnet kann hierbei beispielsweise mit einer Sicherheitseinheit gekoppelt sein, die den Elektromagnet beispielsweise bei einem Bersten des Bearbeitungswerkzeugs 14a aktiviert, um ein Weiterdrehen der Spindel 12a des Winkelschleifers 44a zu verhindern.In an alternative embodiment of the
Des Weiteren weist die als Winkelschleifer 44a ausgebildete tragbare Werkzeugmaschine 10a eine Codierungseinheit 20a auf, die dazu vorgesehen ist, eine Codierung zwischen der Spindel 12a und der an der Spindel 12a montierbaren Ablaufsicherungseinheit 18a zu erzeugen (
In
Ferner weist der Winkelschleifer 44b eine Anzeigeeinheit 138b auf (
Des Weiteren ist die Bremseinheit 16b zusammen mit der Abtriebseinheit 62b als Montagemodul 40b ausgebildet. Das Montagemodul 40b umfasst vier als Schrauben ausgebildete Befestigungselemente (hier nicht dargestellt). Die Schrauben sind dazu vorgesehen, das Montagemodul 40b lösbar mit dem Getriebegehäuse 60b zu verbinden. Ein Bediener kann das Montagemodul 40b bei Bedarf von dem Getriebegehäuse 60b demontieren. Der Winkelschleifer 44b und das Montagemodul 40b bilden somit ein Werkzeugmaschinensystem. Das Werkzeugmaschinensystem umfasst ein weiteres Montagemodul (hier nicht näher dargestellt). Das weitere Montagemodul kann vom Bediener alternativ zum Montagemodul 40b am Getriebegehäuse 60b montiert werden.Furthermore, the
Die Codierungseinheit 20c weist ferner ein zweites Codierungselement 24c auf, das von einem eine Ausnehmung der Ablaufsicherungseinheit 18c begrenzender Rand 136c gebildet wird. Der Rand 136c weist, bezogen auf die Rotationsachse 132c, einen konischen Verlauf auf. In einem montierten Zustand der Ablaufsicherungseinheit 18c liegt das als Kegelstumpf ausgebildete erste Codierungselement 22c an dem Rand 136c an. Die Ablaufsicheurngseinheit 18c wird hierbei drehfest mit der Spindel 12c verbunden.The
Des Weiteren weist der Winkelschleifer 44k eine Codierungseinheit 20k auf, die dazu vorgesehen ist, eine Codierung zumindest zwischen der Spindel 12k und der Ablaufsicherungseinheit 18k zu erzeugen. Die Codierungseinheit 20k ist als mechanische Codierungseinheit 20k ausgebildet. Ferner weist die Codierungseinheit 20k ein erstes Codierungselement 22k auf, das einstückig mit der Spindel 12k ausgebildet ist. Das erste Codierungselement 22k ist, in einer Ebene senkrecht zu einer Rotationsachse 132k der Spindel 12k betrachtet, als Kreissegment 134k ausgebildet (vgl.
