Definitions
- the invention relates to an electric hand tool, in particular an angle grinder, with a housing in which an electric motor is accommodated, which drives a rotor shaft which is connected in a force-transmitting manner to an output unit accommodated in a gear head.
- the electric motor is usually accommodated in the housing and stored therein, the electric motor often being designed as an EC motor and thus comprising a stator with several windings and a rotor with a rotor shaft, the rotor being rotatable about an axis of rotation in the stator is stored.
- a rotor laminated core with a plurality of permanent magnets is held on the rotor shaft, so that a rotating field can be generated in the stator by suitable control, which drives the rotor in order to drive an insert tool, for example a grinding wheel.
- the gear head is screwed onto the housing, but this creates the problem that the alignment of the gear head towards the rotor shaft is often only imprecise. However, this then poses the problem that the service life of the hand-held power tool is adversely affected.
- the preamble of claim 1 is from the US 2018/337575 A1 known.
- JP 2019 013985 A EP 3 290 157 A2 , EP 3 549 717 A1 , US 2017/106490 A1 or JP 2001 009757 A disclosed.
- the present invention is therefore based on the object of reducing the aforementioned disadvantages and providing an improved hand-held power tool.
- a housing ring which provides at least one guide section for the gear head and a guide for the electric motor, an air guide section being formed on the side of the housing ring facing away from the housing is in which a fan attached to the rotor shaft is accommodated.
- the guide is arranged concentrically to the at least one guide section. This further favors the gear head and the electric motor are aligned with each other.
- concentric is also understood in particular to mean that the center points of the guide and those of the at least one guide section lie on a common axis, and it has proven to be particularly preferred if they lie on the axis of rotation.
- the housing ring is arranged in an axially staggered manner between the housing and the gear head. This has particular advantages in terms of assembly technology, which make it easier to connect the gear head to the housing. This means that the gear head is not in direct contact with the housing, but is spaced and separated from the housing by the housing ring.
- the side of the housing ring facing away from the housing is assigned an axial collar on which the at least one guide section for the gear head is formed. This provides an additional guide for the gear head, which also promotes centering and alignment of the gear head relative to the housing ring.
- the number of guide sections is preferably two or more, preferably three or more and more preferably six or less, preferably five or less and particularly preferably four.
- the guide sections are formed like a circular arc, and if the angle of the individual guide sections is preferably 10° or more, preferably 20° or more, particularly preferably 25° or more and more preferably 50° or less, preferably 40° or less and particularly preferably 35° or less and most preferably 30°, then it is possible to further reduce the manufacturing effort.
- the total angle of the guide sections is preferably 60° or more, preferably 80° or more, particularly preferably 100° or more and more preferably 250° or less, preferably 180° or less and particularly preferably 150 ° or less and most preferably 120°. This means that only a few areas of the axial collar need to be adapted to the shape of the gear head.
- the guide is designed on the side of the housing ring facing the housing.
- the guidance ensures that the electric motor can be guided in the housing ring but can also be secured and centered radially, so that the alignment of the electric motor with respect to the gear head is ultimately further improved.
- the guide includes a contact surface for supporting an end face of the electric motor. This also promotes the alignment of the electric motor relative to the housing ring.
- the guide is formed as an annular axial web.
- the annular axial web provides a flat, radial guide in the form of a hollow cylinder for the electric motor, which has a positive effect on the alignment and centering of the electric motor.
- the assembly can be further facilitated by the fact that the axial web has an insertion bevel on the inside circumference. This ensures, in particular, that the electric motor can be inserted into the guide in a simplified manner.
- the alignment of the electric motor relative to the gear head is further promoted by the fact that the housing ring is screwed to the electric motor via a motor screw connection. It has proven useful in this context if the number of screws in the engine screw connection is preferably two or more and more preferably four or fewer and preferably three. In addition, the electric motor connected to the housing ring can be easily installed.
- the electric motor is assigned a motor housing in which receptacles are formed into which the screws of the motor screw connection are screwed. This ensures that there is enough space to form the threads.
- this also has the advantage that the motor housing achieves electrical insulation from the stator of the electric motor, which ensures that the housing ring is doubly insulated from the stator.
- the screws are screwed into another part of the electric motor, for example into the stator of the electric motor.
- the receptacles formed in the motor housing extend essentially over the entire length of the motor housing. This has the advantage that the holder can be used to hold screws from both sides and can therefore also be used, for example, to screw an end cap to the motor housing.
- the housing comprises a first housing part and a second housing part, this has a positive influence on the assembly effort Hand tool according to the invention, since the two housing parts can be easily connected to each other.
- the housing ring connects the first housing part to the second housing part at the end face. This ensures that the position of the two housing parts relative to one another is secured without the two housing parts having to be screwed transversely to the rotor shaft in the front area that borders the gear head. This makes it possible, in particular, to achieve a small gripping dimension.
- the housing ring overlaps the first housing part and/or the second housing part at least partially on the outer circumference.
- the two housing parts are ultimately held from the outside, which further strengthens the securing effect and at the same time also allows the two housing parts to be centered relative to one another.
- the housing ring is overlapped by the two housing parts.
- the housing ring is screwed to the first housing part and/or the second housing part, the screwing taking place parallel to the rotor shaft.
- the two housing parts are firmly connected to the housing ring in their front areas, which has a positive effect on the mechanical strength of the entire housing.
- the number of screws in the screw connection is preferably three or more and more preferably five or fewer and preferably four.
- the housing is vibration-decoupled from the housing ring and/or the gear head. This ensures that the vibrations that occur during operation of the hand-held power tool are not transmitted to the housing and therefore cannot have a detrimental effect on the user of the hand-held power tool.
- housing ring is formed as a housing pot, which forms a receiving space that at least partially accommodates the electric motor.
- Housing ring can therefore be extended in particular axially and ultimately formed as a pot in which the electric motor is at least partially accommodated.
- Figure 1 shows a sectional view along a longitudinal section of an electric hand-held power tool 1, which in the exemplary embodiment shown is formed as a cable-connected angle grinder 2, which is usually operated with voltages between 80 V and 280 V.
- the hand-held power tool 1 has a housing 3, which includes a first housing part 4 and a second housing part 5, both of which are ultimately formed as half-shells.
- the housing 3 accommodates an electric motor 6, which is designed as an EC motor and has several Windings 7 comprising stator 8 and a rotor 9, which is rotatably mounted within the stator 8 about an axis of rotation 10.
- the electric motor 6 drives a rotor shaft 11 connected to the rotor 9, which is connected in a force-transmitting manner to an output unit 13 accommodated in a gear head 12.
- the output unit 13 drives an insert tool 14, which in the present case is formed as a grinding wheel 15.
- a housing ring 16 is arranged, which at least partially engages over the outer circumference of the first housing part 4 and the second housing part 5 and thereby ultimately clamps them.
- housing screws 17.1 are arranged perpendicular to the rotor shaft 11, namely in the area of the housing 3, which faces away from the housing ring 16.
- the housing ring 16 is screwed to the first housing part 4 and the second housing part 5, the screwing taking place parallel to the rotor shaft 11.
- screw domes 18 arranged perpendicular to the rotor shaft 11 in the first housing part 4 and the second housing part 5 in the front area, in which the electric motor 6 is also accommodated, can be dispensed with.
- a total of four screws 17.2 are used for the screw connection, which are screwed from the gear head 12 and ultimately connect the gear head 12, the housing ring 16 and the first housing part 4 and the second housing part 5 to one another.
- two screw receptacles 19 are formed in the first housing part 4 and in the second housing part 5, into which the Screws 17.2 of the screw connection are screwed in.

- corresponding damping elements 20 are provided, which are placed on the screws 17.2 and thus contribute to appropriate damping and decoupling of the housing 3.
- it is screwed to the electric motor 6 via a motor screw connection.
- a total of three motor screws 17.3 are used here, which are screwed into receptacles 21 from the side of the housing ring 16 facing the gear head 12, which are formed in a motor housing 22 in which the electric motor 6 is accommodated and encapsulated in a dust-tight manner.

Description
Die Erfindung betrifft eine elektrische Handwerkzeugmaschine, insbesondere einen Winkelschleifer, mit einem Gehäuse, in dem ein Elektromotor aufgenommen ist, der eine Rotorwelle antreibt, die mit einer in einem Getriebekopf aufgenommenen Abtriebseinheit kraftübertragend verbunden ist.The invention relates to an electric hand tool, in particular an angle grinder, with a housing in which an electric motor is accommodated, which drives a rotor shaft which is connected in a force-transmitting manner to an output unit accommodated in a gear head.
Derartige Handwerkzeugmaschinen sind aus dem Stand der Technik bereits seit langem bekannt, beispielsweise aus der
Der Getriebekopf wird dabei an dem Gehäuse festgeschraubt, wodurch jedoch das Problem besteht, dass die Ausrichtung des Getriebekopfes zu der Rotorwelle hin häufig nur ungenau erfolgt. Dies birgt dann jedoch die Problematik, dass hierdurch die Lebensdauer der Handwerkzeugmaschine nachteilig beeinflusst wird.The gear head is screwed onto the housing, but this creates the problem that the alignment of the gear head towards the rotor shaft is often only imprecise. However, this then poses the problem that the service life of the hand-held power tool is adversely affected.
Der Oberbegriff des Anspruches 1 ist aus der

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die vorgenannten Nachteile zu reduzieren und eine verbesserte Handwerkzeugmaschine bereitzustellen.The present invention is therefore based on the object of reducing the aforementioned disadvantages and providing an improved hand-held power tool.
Diese Aufgabe wird gemäß der Erfindung bei einer Handwerkzeugmaschine der eingangs genannten Art dadurch gelöst, dass ein Gehäusering vorgesehen ist, der mindestens einen Führungsabschnitt für den Getriebekopf und eine Führung für den Elektromotor bereitstellt, wobei an der von dem Gehäuse wegweisenden Seite des Gehäuserings ein Luftleitabschnitt ausgebildet ist, in dem ein auf der Rotorwelle befestigter Lüfter aufgenommen ist.This object is achieved according to the invention in a hand-held power tool of the type mentioned in that a housing ring is provided which provides at least one guide section for the gear head and a guide for the electric motor, an air guide section being formed on the side of the housing ring facing away from the housing is in which a fan attached to the rotor shaft is accommodated.
Hierdurch wird dann erreicht, dass sowohl der Elektromotor als auch der Getriebekopf an diesem Gehäusering geführt und ausgerichtet sind und somit relativ zueinander zentriert werden können. Durch die Integration des Luftleitabschnitts in den Gehäusering und durch die Aufnahme des Lüfters in dem Luftleitabschnitt wird ein sehr kompakter Aufbau realisiert, der es ermöglicht, die Abmessungen der Handwerkzeugmaschine möglichst gering zu halten.This then ensures that both the electric motor and the gear head are guided and aligned on this housing ring and can therefore be centered relative to one another. By integrating the air-guiding section into the housing ring and by accommodating the fan in the air-guiding section, a very compact structure is achieved, which makes it possible to keep the dimensions of the hand-held power tool as small as possible.
Als vorteilhaft hat es sich auch erwiesen, wenn die Führung konzentrisch zu dem mindestens einen Führungsabschnitt angeordnet ist. Hierdurch wird insbesondere weiter begünstigt, dass der Getriebekopf und der Elektromotor zueinander ausgerichtet sind. Unter konzentrisch wird dabei im Rahmen der Erfindung insbesondere auch verstanden, dass die Mittelpunkte der Führung und die des mindestens einen Führungsabschnitts auf einer gemeinsamen Achse liegen, wobei es sich dann als besonders bevorzugt gezeigt hat, wenn diese auf der Rotationsachse liegen.It has also proven to be advantageous if the guide is arranged concentrically to the at least one guide section. This further favors the gear head and the electric motor are aligned with each other. In the context of the invention, concentric is also understood in particular to mean that the center points of the guide and those of the at least one guide section lie on a common axis, and it has proven to be particularly preferred if they lie on the axis of rotation.
Bewährt hat es sich im Rahmen der Erfindung auch, wenn der Gehäusering axial gestaffelt zwischen dem Gehäuse und dem Getriebekopf angeordnet ist. Dies hat insbesondere montagetechnische Vorteile, die es erleichtern, den Getriebekopf mit dem Gehäuse zu verbinden. Die bedeutet, dass der Getriebekopf nicht unmittelbar im Kontakt mit dem Gehäuse steht, sondern durch den Gehäusering von dem Gehäuse beabstandet und getrennt ist.It has also proven useful within the scope of the invention if the housing ring is arranged in an axially staggered manner between the housing and the gear head. This has particular advantages in terms of assembly technology, which make it easier to connect the gear head to the housing. This means that the gear head is not in direct contact with the housing, but is spaced and separated from the housing by the housing ring.
Als günstig hat es sich auch erwiesen, wenn der von dem Gehäuse wegweisenden Seite des Gehäuserings ein Axialbund zugeordnet ist, an dem der mindestens eine Führungsabschnitt für den Getriebekopf ausgebildet ist. Hierdurch wird eine zusätzliche Führung für den Getriebekopf bereitgestellt, die zudem eine Zentrierung und Ausrichtung des Getriebekopfes gegenüber dem Gehäusering begünstigt. In diesem Zusammenhang hat es sich dann auch als vorteilhaft erwiesen, wenn die Anzahl der Führungsabschnitte vorzugsweise zwei oder mehr, bevorzugt drei oder mehr und weiter vorzugsweise sechs oder weniger, bevorzugt fünf oder weniger und besonders bevorzugt vier beträgt.It has also proven to be advantageous if the side of the housing ring facing away from the housing is assigned an axial collar on which the at least one guide section for the gear head is formed. This provides an additional guide for the gear head, which also promotes centering and alignment of the gear head relative to the housing ring. In this context, it has also proven to be advantageous if the number of guide sections is preferably two or more, preferably three or more and more preferably six or less, preferably five or less and particularly preferably four.
Wenn die Führungsabschnitte kreisbogenartig gebildet sind, und wenn der Winkel der einzelnen Führungsabschnitte vorzugsweise 10° oder mehr, bevorzugt 20° oder mehr, besonders bevorzugt 25° oder mehr und weiter vorzugsweise 50° oder weniger, bevorzugt 40° oder weniger und besonders bevorzugt 35° oder weniger und ganz besonders bevorzugt 30° beträgt, dann ist es möglich, den Herstellungsaufwand weiter zu reduzieren. In diesem Zusammenhang hat es sich dann auch bewährt, wenn der Gesamtwinkel der Führungsabschnitte vorzugsweise 60° oder mehr, bevorzugt 80° oder mehr, besonders bevorzugt 100° oder mehr und weiter vorzugsweise 250° oder weniger, bevorzugt 180° oder weniger und besonders bevorzugt 150° oder weniger und ganz besonders bevorzugt 120° beträgt. Somit müssen nur wenige Bereiche des Axialbunds an die Form des Getriebekopfes angepasst werden.If the guide sections are formed like a circular arc, and if the angle of the individual guide sections is preferably 10° or more, preferably 20° or more, particularly preferably 25° or more and more preferably 50° or less, preferably 40° or less and particularly preferably 35° or less and most preferably 30°, then it is possible to further reduce the manufacturing effort. In this context, it has also proven useful if the total angle of the guide sections is preferably 60° or more, preferably 80° or more, particularly preferably 100° or more and more preferably 250° or less, preferably 180° or less and particularly preferably 150 ° or less and most preferably 120°. This means that only a few areas of the axial collar need to be adapted to the shape of the gear head.
Als besonders günstig hat es sich auch erwiesen, wenn die Führung auf der dem Gehäuse zugewandten Seite des Gehäuserings ausgebildet ist. Durch die Führung wird erreicht, dass der Elektromotor in dem Gehäusering geführt aber auch radial gesichert und zentriert werden kann, so dass hierdurch letztlich die Ausrichtung des Elektromotors gegenüber dem Getriebekopf weiter verbessert wird. In diesem Zusammenhang hat es sich aber auch als vorteilhaft erwiesen, wenn die Führung eine Anlagefläche zur Abstützung einer Stirnseite des Elektromotors umfasst. Auch hierdurch wird die Ausrichtung des Elektromotors relativ zu dem Gehäusering begünstigt.It has also proven to be particularly favorable if the guide is designed on the side of the housing ring facing the housing. The guidance ensures that the electric motor can be guided in the housing ring but can also be secured and centered radially, so that the alignment of the electric motor with respect to the gear head is ultimately further improved. In this context, it has also proven to be advantageous if the guide includes a contact surface for supporting an end face of the electric motor. This also promotes the alignment of the electric motor relative to the housing ring.
Als vorteilhaft hat es sich auch erwiesen, wenn die Führung als ein ringförmiger Axialsteg gebildet ist. Durch den ringförmigen Axialsteg wird eine flächige, radiale Führung in Form eine Hohlzylinders für den Elektromotor bereitgestellt, was sich damit positiv auf die Ausrichtung und Zentrierung des Elektromotors auswirkt.It has also proven to be advantageous if the guide is formed as an annular axial web. The annular axial web provides a flat, radial guide in the form of a hollow cylinder for the electric motor, which has a positive effect on the alignment and centering of the electric motor.
Die Montage kann noch dadurch begünstigt werden, dass der Axialsteg innenumfangseitig eine Einführschräge aufweist. Hierdurch wird dann insbesondere erreicht, dass der Elektromotor vereinfacht in die Führung eingesetzt werden kann.The assembly can be further facilitated by the fact that the axial web has an insertion bevel on the inside circumference. This ensures, in particular, that the electric motor can be inserted into the guide in a simplified manner.
Die Ausrichtung des Elektromotors relativ zu dem Getriebekopf wird noch dadurch weiter begünstigt, dass der Gehäusering mit dem Elektromotor über eine Motorverschraubung verschraubt ist. Wobei es sich in diesem Zusammenhang bewährt hat, wenn die Anzahl der Schrauben der Motorverschraubung vorzugsweise zwei oder mehr und weiter vorzugsweise vier oder weniger und bevorzugt drei beträgt. Zudem kann der mit dem Gehäusering verbundene Elektromotor dadurch einfach montiert werden.The alignment of the electric motor relative to the gear head is further promoted by the fact that the housing ring is screwed to the electric motor via a motor screw connection. It has proven useful in this context if the number of screws in the engine screw connection is preferably two or more and more preferably four or fewer and preferably three. In addition, the electric motor connected to the housing ring can be easily installed.
Als besonders günstig hat es sich auch erwiesen, wenn dem Elektromotor ein Motorgehäuse zugeordnet ist, in dem Aufnahmen ausgebildet sind, in die die Schrauben der Motorverschraubung eingeschraubt sind. Hierdurch wird sichergestellt, dass ausreichend Platz vorhanden ist, um die Gewindegänge auszubilden. Insbesondere hat dies aber auch den Vorteil, dass durch das Motorgehäuse eine elektrische Isolation gegenüber dem Stator des Elektromotors erreicht wird, die sicherstellt, dass der Gehäusering doppelt gegenüber dem Stator isoliert ist. Im Rahmen der Erfindung ist es aber auch vorgesehen, dass die Schrauben in einen anderen Teil des Elektromotors geschraubt werden, beispielsweise in den Stator des Elektromotors.It has also proven to be particularly advantageous if the electric motor is assigned a motor housing in which receptacles are formed into which the screws of the motor screw connection are screwed. This ensures that there is enough space to form the threads. In particular, this also has the advantage that the motor housing achieves electrical insulation from the stator of the electric motor, which ensures that the housing ring is doubly insulated from the stator. However, within the scope of the invention it is also provided that the screws are screwed into another part of the electric motor, for example into the stator of the electric motor.
Als günstig hat es sich aber auch gezeigt, wenn sich die in dem Motorgehäuse ausgebildeten Aufnahmen im Wesentlichen über die gesamte Länge des Motorgehäuses erstrecken. Dies hat den Vorteil, dass die Aufnahme von beiden Seiten her für die Aufnahme von Schrauben dienen kann und damit auch dazu verwendet werden kann, beispielsweise eine Abschlusskappe mit dem Motorgehäuse zu verschrauben.However, it has also proven to be advantageous if the receptacles formed in the motor housing extend essentially over the entire length of the motor housing. This has the advantage that the holder can be used to hold screws from both sides and can therefore also be used, for example, to screw an end cap to the motor housing.
Wenn das Gehäuse ein erstes Gehäuseteil und ein zweites Gehäuseteil umfasst, so hat dies einen positiven Einfluss auf den Montageaufwand der erfindungsgemäßen Handwerkzeugmaschine, da die beiden Gehäuseteile einfach miteinander verbunden werden können.If the housing comprises a first housing part and a second housing part, this has a positive influence on the assembly effort Hand tool according to the invention, since the two housing parts can be easily connected to each other.
Als vorteilhaft hat es sich auch erwiesen, wenn der Gehäusering stirnseitig das erste Gehäuseteil mit dem zweiten Gehäuseteil verbindet. Hierdurch wird gewährleistet, dass die Lage der beiden Gehäuseteile zueinander gesichert ist, ohne dass im stirnseitigen Bereich, der an den Getriebekopf grenzt, eine Verschraubung der beiden Gehäuseteile quer zur Rotorwelle erfolgen müsste. Hierdurch lässt sich dann insbesondere ein geringes Greifmaß realisieren.It has also proven to be advantageous if the housing ring connects the first housing part to the second housing part at the end face. This ensures that the position of the two housing parts relative to one another is secured without the two housing parts having to be screwed transversely to the rotor shaft in the front area that borders the gear head. This makes it possible, in particular, to achieve a small gripping dimension.
Als besonders günstig hat es sich hierbei auch erwiesen, wenn der Gehäusering das erste Gehäuseteil und/oder das zweite Gehäuseteil zumindest teilweise außenumfangsseitig übergreift. Hierdurch werden die beiden Gehäuseteile letztlich von außen gehalten, was die Sicherungswirkung noch verstärkt und zugleich auch eine Zentrierung der beiden Gehäuseteile zueinander erlaubt. Im Rahmen der Erfindung ist es aber auch vorgesehen, dass der Gehäusering von den beiden Gehäuseteilen übergriffen wird.It has also proven to be particularly advantageous if the housing ring overlaps the first housing part and/or the second housing part at least partially on the outer circumference. As a result, the two housing parts are ultimately held from the outside, which further strengthens the securing effect and at the same time also allows the two housing parts to be centered relative to one another. However, within the scope of the invention it is also provided that the housing ring is overlapped by the two housing parts.
Als vorteilhaft hat es sich auch erwiesen, wenn der Gehäusering mit dem ersten Gehäuseteil und/oder dem zweiten Gehäuseteil verschraubt ist, wobei die Verschraubung parallel zur Rotorwelle erfolgt. Hierdurch werden die beiden Gehäuseteile also in ihren stirnseitigen Bereichen fest mit dem Gehäusering verbunden, was sich positiv auf die mechanische Belastbarkeit des gesamten Gehäuses auswirkt. Als günstig hat es sich in diesem Zusammenhang auch gezeigt, wenn die Anzahl der Schrauben der Verschraubung vorzugsweise drei oder mehr und weiter vorzugsweise fünf oder weniger und bevorzugt vier beträgt.It has also proven to be advantageous if the housing ring is screwed to the first housing part and/or the second housing part, the screwing taking place parallel to the rotor shaft. As a result, the two housing parts are firmly connected to the housing ring in their front areas, which has a positive effect on the mechanical strength of the entire housing. In this context, it has also proven to be advantageous if the number of screws in the screw connection is preferably three or more and more preferably five or fewer and preferably four.
Um den Montageaufwand weiter zu reduzieren, hat es sich dann noch als vorteilhaft erwiesen, wenn in dem ersten Gehäuseteil und in dem zweiten Gehäuseteil jeweils mindestens zwei Schraubenaufnahmen ausgebildet sind, in die die Schrauben der Verschraubung eingeschraubt sind. Dabei hat es sich dann auch besonders bewährt, wenn die Verschraubung durch den Getriebekopf hindurch erfolgt. Hierdurch wird dann letztlich eine Einheit gebildet, die aus Getriebekopf, Gehäusering und den beiden Gehäuseteilen besteht und durch die Verschraubung gesichert ist.In order to further reduce the assembly effort, it has proven to be advantageous if at least two screw receptacles are formed in the first housing part and in the second housing part, into which the screws of the screw connection are screwed. It has also proven particularly useful if the screw connection takes place through the gear head. This then ultimately forms a unit which consists of the gear head, housing ring and the two housing parts and is secured by the screw connection.
Als vorteilhaft hat es sich auch erwiesen, wenn auf der dem Gehäuse zuweisenden Seite des Gehäuserings kreissegmentartige Vorsprünge ausgebildet sind, die die Schraubenaufnahmen außenumfangsseitig zumindest teilweise überdecken. Hierdurch wird eine weitere Sicherung der Schrauben der Gehäuseteile erreicht und gleichzeitig auch sichergestellt, dass die Schraubenaufnahmen überdeckt sind, wodurch eine verbesserte Zentrierung der beiden Gehäuseteile relativ zu dem Gehäusering erreicht wird.It has also proven to be advantageous if circular segment-like projections are formed on the side of the housing ring facing the housing, which at least partially cover the screw receptacles on the outer circumference. This further secures the screws of the housing parts and at the same time ensures that the screw receptacles are covered, thereby achieving improved centering of the two housing parts relative to the housing ring.
Als besonders günstig hat es sich auch erwiesen, wenn das Gehäuse gegenüber dem Gehäusering und/oder dem Getriebekopf vibrationsentkoppelt ist. Hierdurch wird erreicht, dass die beim Betrieb der Handwerkzeugmaschine auftretenden Vibrationen nicht auf das Gehäuse übertragen werden und sich damit nicht nachteilig auf den Nutzer der Handwerkzeugmaschine auswirken können.It has also proven to be particularly advantageous if the housing is vibration-decoupled from the housing ring and/or the gear head. This ensures that the vibrations that occur during operation of the hand-held power tool are not transmitted to the housing and therefore cannot have a detrimental effect on the user of the hand-held power tool.
Als besonders günstig hat es sich aber auch erwiesen, wenn der Gehäusering als ein Gehäusetopf gebildet ist, der einen den Elektromotor zumindest teilweise aufnehmenden Aufnahmeraum bildet. Hierbei kann der Gehäusering also insbesondere axial verlängert und letztlich als Topf gebildet sein, in dem der Elektromotor zumindest teilweise aufgenommen ist.However, it has also proven to be particularly favorable if the housing ring is formed as a housing pot, which forms a receiving space that at least partially accommodates the electric motor. Here he can Housing ring can therefore be extended in particular axially and ultimately formed as a pot in which the electric motor is at least partially accommodated.
