Der Getriebeeinheit ist ein antriebsseitiger Getriebeflansch zugeordnet, der die Getriebeeinheit verschließt. Hierbei ist der Getriebeflansch in axialer Richtung der Getriebeeinheit beabstandet zum Antriebsmotor angeordnet.Such a handheld power tool with a housing in which a gear unit and an electronically commutated drive motor are arranged is known from the prior art.

Die vorliegende Erfindung betrifft eine Handwerkzeugmaschine mit einer Werkzeugaufnahme und einem Gehäuse, in dem zumindest eine Getriebeeinheit, sowie ein elektronisch kommutierter Antriebsmotor mit einem Stator und einem Rotor zum Antrieb eines in der Werkzeugaufnahme anordenbaren Einsatzwerkzeugs angeordnet sind, wobei der Getriebeeinheit ein antriebsseitiger Getriebeflansch zugeordnet ist, der die Getriebeeinheit zumindest abschnittsweise verschließt. Der antriebsseitige Getriebeflansch weist an seiner dem Stator zugewandten Stirnseite einen Aufnahmebereich zur zumindest abschnittsweisen Aufnahme von zumindest einer dem Stator zugeordneten Motorkomponente auf.The present invention relates to a handheld power tool with a tool holder and a housing in which at least one gear unit and an electronically commutated drive motor with a stator and a rotor for driving an insert tool that can be arranged in the tool holder are arranged, the gear unit being assigned a drive-side gear flange, which closes the gear unit at least in sections. The drive-side gear flange has, on its end face facing the stator, a receiving area for receiving at least one motor component assigned to the stator, at least in sections.
Die Erfindung ermöglicht somit die Bereitstellung einer Handwerkzeugmaschine, bei der durch den Aufnahmebereich eine kurze und kompakte Bauform der Handwerkzeugmaschine ermöglicht werden kann. Somit kann insbesondere einfach und unkompliziert eine verbesserte Lagerung einer dem Antriebsmotor zugeordneten Antriebswelle ermöglicht werden.The invention thus makes it possible to provide a handheld power tool in which a short and compact design of the handheld power tool can be made possible through the receiving area. In this way, an improved mounting of a drive shaft assigned to the drive motor can be made possible in a particularly simple and uncomplicated manner.
Im Kontext der vorliegenden Erfindung wird unter dem Begriff "Motorkomponente" ein der Antriebseinheit, insbesondere dem Antriebsmotor, zugeordnetes und insbesondere am Antriebsmotor befestigtes Bauteil verstanden, sodass z.B. eine Motorwelle des Antriebsmotors im Kontext der vorliegenden Erfindung nicht als Motorkomponente zu verstehen ist. Die Motorkomponente ist dabei zwischen dem Antriebsmotor und der Getriebeeinheit, insbesondere einem Getriebeflansch, angeordnet. Die zumindest eine Motorkomponente kann dabei als mechanische Motorkomponente, z.B. als Verdrehsicherungssteg des Antriebmotors, insbesondere des Stators des Antriebsmotors, als elektromechanische Motorkomponente, beispielhaft als Motorterminal und/oder als elektrische Motorkomponente, z.B. als Elektronikplatine, d.h. als Platine mit elektronischen Bauteilen, ausgebildet sein.In the context of the present invention, the term "motor component" is understood to mean a component assigned to the drive unit, in particular the drive motor, and in particular attached to the drive motor, so that e.g. a motor shaft of the drive motor is not to be understood as a motor component in the context of the present invention. The motor component is arranged between the drive motor and the gear unit, in particular a gear flange. The at least one motor component can be designed as a mechanical motor component, e.g. as an anti-rotation web of the drive motor, in particular the stator of the drive motor, as an electromechanical motor component, for example as a motor terminal and / or as an electrical motor component, e.g. as an electronic circuit board, i.e. as a circuit board with electronic components.
Bevorzugt weist der Aufnahmebereich zumindest ein Aufnahmeelement in Umfangsrichtung des antriebsseitigen Getriebeflanschs zur Aufnahme der zumindest einen Motorkomponente auf. Somit kann auf einfache Art und Weise eine kompakte Antriebseinheit und dadurch eine kompakte Handwerkzeugmaschine bereitgestellt werden.The receiving area preferably has at least one receiving element in the circumferential direction of the drive-side gear flange for receiving the at least one motor component. A compact drive unit and thereby a compact handheld power tool can thus be provided in a simple manner.
Vorzugsweise sind Stege vorgesehen, die zur Ausbildung des zumindest einen dem Aufnahmebereich zugeordneten Aufnahmeelements ausgebildet sind. Somit kann ein robuster und stabiler Aufnahmebereich ausgebildet werden.Preferably, webs are provided which are designed to form the at least one receiving element assigned to the receiving area. A robust and stable receiving area can thus be formed.
Gemäß einer Ausführungsform ist das zumindest eine dem Aufnahmebereich zugeordnete Aufnahmeelement als Ausnehmung ausgebildet. Somit kann leicht und zuverlässig der Aufnahmebereich ausgebildet werden.According to one embodiment, the at least one receiving element assigned to the receiving area is designed as a recess. Thus can easily and the receiving area can be reliably formed.
Das zumindest eine Aufnahmeelement ist bevorzugt zur zumindest abschnittsweisen Aufnahme der dem Stator zugeordneten, zumindest einen Motorkomponente ausgebildet, bevorzugt zur Aufnahme von Motorterminals. Somit kann die kompakte Bauform der Handwerkzeugmaschine durch eine verschachtelte Anordnung des Stators und des Getriebeflanschs auf einfache Art und Weise ermöglicht werden. Unter dem Begriff "Motorterminal" wird im Kontext der vorliegenden Erfindung z.B. ein Verschalteelement zum Verschalten einer Motorwicklung des Antriebsmotors verstanden. Die Motorterminals sind bevorzugt als Drahtelemente ausgebildet, die über eine Verschalteeinheit, z.B. eine Verschalteplatte, miteinander verbunden sind.The at least one receiving element is preferably designed to receive the at least one motor component assigned to the stator, at least in sections, preferably to receive motor terminals. The compact design of the handheld power tool can thus be made possible in a simple manner by a nested arrangement of the stator and the gear flange. In the context of the present invention, the term "motor terminal" is understood to mean, for example, an interconnection element for interconnection of a motor winding of the drive motor. The motor terminals are preferably designed as wire elements that are connected to one another via an interconnection unit, e.g. an interconnection plate.
Vorzugsweise ist das zumindest eine Aufnahmeelement derart ausgebildet, dass die zumindest eine Motorkomponente Lagerelemente zur Lagerung des antriebsseitigen Getriebeflanschs in Längsrichtung der Antriebseinheit bzw. des Antriebsmotors überragen. Somit kann eine sichere und robuste Lagerung ermöglicht werden.The at least one receiving element is preferably designed such that the at least one motor component protrudes beyond bearing elements for mounting the drive-side gear flange in the longitudinal direction of the drive unit or the drive motor. Safe and robust storage can thus be made possible.
Der antriebsseitige Getriebeflansch weist bevorzugt an seinem ersten axialen Ende einen ersten Lagerungsbereich zur Anordnung eines ersten Lagerelements auf und weist einen von dem ersten Lagerungsbereich beabstandeten zweiten Lagerungsbereich zur Anordnung eines zweiten Lagerelements auf. Somit kann eine einfache und zuverlässige Lagerung ermöglicht werden.The drive-side gear flange preferably has at its first axial end a first bearing area for the arrangement of a first bearing element and has a second bearing area, spaced from the first bearing area, for the arrangement of a second bearing element. Simple and reliable storage can thus be made possible.
Gemäß einer Ausführungsform weist der erste Lagerungsbereich einen ersten Außendurchmesser auf und der zweite Lagerungsbereich weist einen zweiten Außendurchmesser auf, der größer als der erste Außendurchmesser ist. Somit kann ein Lagerungsbereich im Bereich des Aufnahmebereichs angeordnet werden, wodurch die Bereitstellung eines vergleichsweise kurzen Getriebeflanschs ermöglicht werden kann.According to one embodiment, the first storage area has a first outer diameter and the second storage area has a second outer diameter that is larger than the first outer diameter. Thus, a storage area can be arranged in the area of the receiving area, whereby the provision of a comparatively short gear flange can be made possible.
Vorzugsweise weist der Getriebeflansch einen Innenraum zur Anordnung der Getriebeeinheit auf, wobei eine abtriebsseitige Stirnseite des Aufnahmebereichs des Getriebeflanschs Aufnahmen aufweist, wobei das Hohlrad der Getriebeeinheit zur Ausbildung einer Verdrehsicherung abschnittsweise in den Aufnahmen angeordnet ist. Somit kann auf einfache Art und Weise eine Verdrehsicherung des Hohlrads im Getriebeflansch bereitgestellt werden.The gear flange preferably has an interior space for the arrangement of the gear unit, an output-side end face of the receiving area of the gear flange having receptacles, the ring gear of the gear unit in sections in the receptacles in order to form an anti-rotation device is arranged. A rotation lock of the ring gear in the transmission flange can thus be provided in a simple manner.
Bevorzugt ist die Handwerkzeugmaschine als Drehschlagschrauber mit einem Schlagwerk ausgebildet, wobei das Schlagwerk der Getriebeeinheit zugeordnet ist. Somit kann das Schlagwerk einfach und unkompliziert zumindest abschnittsweise im Getriebeflansch angeordnet werden.The handheld power tool is preferably designed as a rotary impact wrench with an impact mechanism, the impact mechanism being assigned to the gear unit. Thus, the hammer mechanism can be arranged in a simple and uncomplicated manner, at least in sections, in the gear flange.
Gemäß einer Ausführungsform ist die zumindest eine Motorkomponente eine dem Antriebsmotor zugeordnete Platine mit elektronischen Bauteilen. Somit kann die kompakte Bauform der Handwerkzeugmaschine durch eine verschachtelte Anordnung des Antriebsmotors und der Platine ermöglicht werden.According to one embodiment, the at least one motor component is a circuit board with electronic components assigned to the drive motor. The compact design of the handheld power tool can thus be made possible by a nested arrangement of the drive motor and the circuit board.
Gemäß einer Ausführungsform ist die zumindest eine Motorkomponente ein dem Antriebsmotor zugeordneter in Längsrichtung des Antriebsmotors ausgebildeter Verdrehsicherungssteg. Somit kann einfach und unkompliziert eine verschachtelte Anordnung des Antriebsmotors und des Verdrehsicherungsstegs ermöglicht werden, wobei durch den Verdrehsicherungssteg ein Verdrehen des Stators im Betrieb des Antriebsmotors verhindert werden kann, so dass simpel und unkompliziert eine Verdrehsicherung bereitgestellt werden kann.According to one embodiment, the at least one motor component is an anti-rotation web which is assigned to the drive motor and is formed in the longitudinal direction of the drive motor. Thus, a nested arrangement of the drive motor and the anti-rotation web can be made possible in a simple and uncomplicated manner, the rotation of the stator can be prevented by the anti-rotation web during operation of the drive motor, so that an anti-rotation device can be provided in a simple and uncomplicated manner.
Vorzugsweise weist der Getriebeflansch eine dem zumindest einen Verdrehsicherungssteg zugeordnete Ausnehmung auf, um ein Durchdringen des zumindest einen Verdrehsicherungsstegs in den Getriebeflansch hinein zu ermöglichen. Somit kann eine kompakte Anordnung der Motorkomponente und des Getriebeflansches ermöglicht werden, wobei der Verdrehsicherungssteg zur Ausbildung einer Verdrehsicherung des Stators des Antriebsmotors dient.The gear flange preferably has a recess assigned to the at least one anti-rotation web in order to enable the at least one anti-rotation web to penetrate into the gear flange. A compact arrangement of the motor component and the gear flange can thus be made possible, with the anti-rotation web serving to provide anti-rotation protection for the stator of the drive motor.
