Description

Stand der TechnikState of the art

Die vorliegende Erfindung geht aus von einer Handwerkzeugmaschine mit Spindelstop nach dem Oberbegriff des Anspruchs 1. Ein Beispiel einer solchen Handwerkzeugmaschine ist gezeigt in DE-A-2816398. Zu den bekannten Handwerkzeugmaschinen mit Spindelstop gehören Winkelschleifer und Handkreissägen. Bei diesen Maschinen muss die Abtriebswelle zum Werkzeugwechsel am Drehen gehindert werden, damit die jeweilige das Sägeblatt oder die Schleifscheibe an der Abtriebswelle festhaltende Sicherungsschraube gelöst werden kann. Dabei nimmt die Spindelstopeinrichtung das beim Lösen der Mutter auftretende Drehmoment auf.The present invention is based on a handheld power tool with spindle stop according to the preamble of claim 1. An example of such a handheld power tool is shown in DE-A-2816398. The well-known hand tool machines with spindle stop include angle grinders and circular saws. In these machines, the output shaft must be prevented from rotating for tool change so that the respective locking screw holding the saw blade or the grinding wheel on the output shaft can be released. The Spindelstopeinrichtung takes on the torque occurring when loosening the nut.

Als Spindelstop dienen üblicherweise zylindrische Sperrbolzen, die in Längsrichtung verschoben werden und dabei mit ihrem Ende formschlüssig in ein drehfest mit der Abtriebswelle gekoppeltes Teil oder auch unmittelbar in die Abtriebswelle eingreifen.As spindle stop usually serve cylindrical locking pin, which are displaced in the longitudinal direction and thereby engage positively with its end in a rotatably coupled to the output shaft part or directly into the output shaft.

Die Sperrbolzen durchtreten längsverschiebbar gelagert das Gehäuse der Handwerkzeugmaschinen. Dabei unterliegt das Gehäuse im Durchtrittsbereich des Sperrbolzens hohem Verschleiß, z.B. durch Betätigung des Spindelstops bei laufender Abtriebswelle oder bei übermäßig hohem Lösemoment bei festgerosteter Sicherungsmutter der Sägeblätter oder der Schleifscheiben. Dies führt zu zunehmendem Spiel zwischen dem Sperrbolzen und der Führungsbuchse und beeinträchtigt die Funktion des Spindelstops. Außerdem kann sich die Führungsbuchse zur Längsführung des Sperrbolzens im Getriebegehäuse lösen und weiten. Dadurch kann entlang dem Sperrbolzen Getriebefett aus- bzw. Staub eintreten, so daß das Gehäuse außen verschmutzt und die bewegten Teile im Inneren des Gehäuses infolge Fettmangel ungenügend geschmiert sind.The locking pins pass longitudinally displaceably mounted the housing of the power tool. In this case, the housing is subject to high wear in the passage region of the locking bolt, for example by operating the spindle stop when the output shaft is running or when the release torque of the saw blades or the grinding wheels is excessively high. This leads to increasing play between the locking pin and the guide bush and impairs the function of the spindle stop. In addition, the guide bush to the longitudinal guidance of the locking pin in the transmission housing can solve and expand. As a result, along the locking pin gear grease off or dust occur, so that the outside of the housing dirty and the moving parts are insufficiently lubricated inside the housing due to lack of fat.

Vorteile der ErfindungAdvantages of the invention

Durch die Ausgestaltung der Handwerkzeugmaschine mit den Merkmalen des Anspruchs 1 wird diese kostengünstiger herstellbar, weil im Durchtrittsbereich des Sperrbolzens am Gehäuse auf eine Führungsbuchse verzichtet werden kann, wobei die Längsführung des Sperrbolzens dichter und robuster ist. Außerdem ist durch die Ausgestaltung des Sperrbolzens das Gehäuse gegen Fettaustritt und gegen den Eintritt von Staub und Schmutz von außen besser gesichert.Due to the configuration of the power tool with the features of claim 1, this is cheaper to produce, because in the passage region of the locking bolt on the housing can be dispensed with a guide bush, the longitudinal guide of the locking bolt is denser and more robust. In addition, the housing is better protected by the design of the locking bolt against grease leakage and against the entry of dust and dirt from the outside.

Dadurch, daß der Sperrbolzen einen größeren Durchmesser hat und die Durchgangsbohrung ihn unmittelbar führend umgreift, kann die Flächenpressung verringert werden und bei Verzicht auf eine Führungsbuchse die Dichtheit verbessert werden.The fact that the locking pin has a larger diameter and the through hole surrounds him immediately leader, the surface pressure can be reduced and the absence of a guide bushing the tightness can be improved.

Dadurch, daß der Sperrbolzen etwa mittig einen O-Ring in einer Ringnut trägt, ist auch bei Höchstbelastung des Sperrbolzens während der Betätigung des Spindelstops die Dichtheit zwischen der Durchgangsbohrung bzw. Schiebeführung und dem Sperrbolzen gesichert.The fact that the locking pin carries approximately centrally an O-ring in an annular groove, the tightness between the through hole or sliding guide and the locking pin is secured even at maximum load of the locking pin during operation of the spindle stop.

Dadurch, daß der Sperrbolzen vor seinem formschlüssig in die Abtriebswelle greifbaren Bereich eine bundartige, radiale Verbreiterung trägt, die in der Ruheposition des Sperrbolzens stirnseitig an der Wand des Getriebegehäuses anliegt, ist eine axiale Dichtung geschaffen, die den Austritt von Schmiermittel nach außen aus dem Gehäuse verhindert.Characterized in that the locking pin carries a collar-like, radial widening in front of his form-fit tangible in the output shaft area, which rests in the rest position of the locking pin frontally on the wall of the transmission housing, an axial seal is provided, the outlet of lubricant to the outside of the housing prevented.

Dadurch, daß der Sperrbolzen an seinem oberen Ende in einen Hals übergeht und dort eine aufsetzbare, als Taste dienende Kappe trägt, ist der Spindelstop einfach montierbar und demontierbar sowie bequem betätigbar.Characterized in that the locking pin merges at its upper end in a neck and there carries an attachable, serving as a key cap, the spindle stop is easy to install and disassemble and easy to operate.

Dadurch, daß der Sperrbolzen zwischen der als Taste dienenden Kappe und dem Teil der Stufenbohrung mit dem größeren Durchmesser eine Feder trägt, wird der Sperrbolzen zuverlässig in seiner Ruheposition und die bundartige Verbreiterung in Anschlaglage an der Innenwand des Gehäuses in ihrer Dichtposition gehalten.Characterized in that the locking pin carries a spring between the serving as a key cap and the portion of the stepped bore with the larger diameter, the locking pin is reliably held in its rest position and the collar-like widening in abutment against the inner wall of the housing in its sealing position.

Dadurch, daß der Hals des Sperrbolzens eine Rastnut und die als Taste dienende Kappe einen inneren Rastzylinder hat, ist die Montage der Kappe auf dem Sperrbolzen besonders einfach und robust.The fact that the neck of the locking pin has a locking groove and serving as a key cap has an inner locking cylinder, the mounting of the cap on the locking pin is particularly simple and robust.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Figur 1 zeigt einen Teil-Längsschnitt einer als Winkelschleifer ausgestalteten Handwerkzeugmaschine 10. In deren hinteren Bereich trägt ein Gehäuse 12 einen Elektromotor 14 mit einer Motorwelle 16, in seinem vorderen Bereich ein Winkelgetriebe 18. Das Winkelgetriebe 18 besteht aus einer Schleifspindel 20, die mit ihrem freien Ende unten aus dem Gehäuse 12 ragt. Daran ist ein nicht näher bezeichnetes Gewinde angeordnet, auf das eine Mutter 24 aufschraubbar ist, die eine zuvor mit ihrer nicht näher bezeichneten Bohrung über das freie Ende 19 der Schleifspindel gesetzte Schleifscheibe 22 festhält. Die Schleifscheibe 22 wird dabei zwischen einem Bund 23 der Abtriebswelle 20 und der Mutter 24 axial eingespannt.FIG. 1 shows a partial longitudinal section of a hand tool machine designed as an angle grinder 10. In the rear region, a housing 12 carries an electric motor 14 with a motor shaft 16, an angle gear 18 in its front region. The angle gear 18 consists of a grinding spindle 20, which with its free end down from the housing 12 protrudes. This is a unspecified thread arranged on a nut 24 is screwed, which has a previously with her unspecified bore over the free end 19 of the grinding spindle set grinding wheel 22 holds. The grinding wheel 22 is clamped axially between a collar 23 of the output shaft 20 and the nut 24.

Das Winkelgetriebe 18 besteht aus einem kleinen Kegelritzel 28, das am Ende der Motorwelle 16 drehfest angeordnet ist und aus einem großen Kegelrad 30. Das Kegelritzel 28 greift in das Kegelrad 30, das drehfest an der Abtriebswelle 20 festgelegt ist. Das Kegelrad 30 weist auf seiner Oberseite mindestens eine Vertiefungen 32 auf, in die ein Sperrbolzen 36 paßt, der zu einem Spindelstop 34 gehört. Der Sperrbolzen 36 ist in einer Schiebeführung 35 längs verschiebbar gelagert, indem er die Wandung des Gehäuses 12 nach außen ragend durchtritt, wobei er mit einem größeren Bereich ins Innere des Gehäuses 12 ragt. Die Schiebeführung 35 ist als Stufenbohrung 37 ausgestaltet, deren größerer Durchmesser nach außen gewandt ist und deren kleinerer Durchmesser den Umfang des zylindrischen Sperrbolzens 36 dichtend umgreift.The angle gear 18 consists of a small bevel pinion 28 which is rotatably disposed at the end of the motor shaft 16 and a large bevel gear 30. The bevel pinion 28 engages in the bevel gear 30 which is rotatably fixed to the output shaft 20. The bevel gear 30 has on its upper side at least one recesses 32 into which a locking pin 36 fits, which belongs to a spindle stop 34. The locking pin 36 is mounted longitudinally displaceable in a sliding guide 35 by passing through the wall of the housing 12 projecting outwardly, wherein it projects with a larger area into the interior of the housing 12. The sliding guide 35 is designed as a stepped bore 37, whose larger diameter is turned outward and whose smaller diameter surrounds the circumference of the cylindrical locking pin 36 sealingly.

Der Sperrbolzen 36 hat an seinem unteren Ende 38 einen Zapfen 39 zum Eingriff in eine der Vertiefungen 32 des Kegelrades 30.The locking pin 36 has at its lower end 38 a pin 39 for engagement in one of the recesses 32 of the bevel gear 30th

Der Zapfen 39 hat einen kleineren Durchmesser als der übrige Bereich des Sperrbolzens 36. Am Übergang zwischen dem Zapfen 39 und dem Sperrbolzen 36 schließt sich ein radial überstehender, scheibenartiger Dichtungsbund 40 an. Dieser liegt axial an der Innenwand des Gehäuses 12 an und übergreift damit die Mündung der Schiebeführung 35 bzw. der Stufenbohrung 37.The pin 39 has a smaller diameter than the remaining area of the locking pin 36. At the transition between the pin 39 and the locking pin 36, a radially projecting, disc-like sealing collar 40 connects. This is axially against the inner wall of the housing 12 and thus engages over the mouth of the sliding guide 35 and the stepped bore 37th

Der Sperrbolzen 36 trägt etwa mittig eine Ringnut 41, in die ein O-Ring 43 eingelegt ist. Dieser liegt dichtend zwischen dem Sperrbolzen 36 und der Schiebeführung 35 an und verhindert auch bei starker Beanspruchung des Zapfens 39 beim Eingriff in die Vertiefung 32 bei Betätigung des Spindelstops 34 ein Austreten von Schmiermittel aus dem Gehäuse 12. Damit ist eine zuverlässige Dichtung zwischen der Schiebeführung 35 und dem Sperrbolzen 36 erreicht.The locking pin 36 carries approximately centrally an annular groove 41, in which an O-ring 43 is inserted. This is sealingly between the locking pin 36 and the sliding guide 35 and prevents even with heavy use of the pin 39 during engagement in the recess 32 upon actuation of the spindle stop 34, a leakage of lubricant from the housing 12. Thus, a reliable seal between the sliding guide 35 and the locking pin 36 is reached.

In seinem oberen Bereich geht der Sperrbolzen 36 an Schultern 45 in einen Hals 47 über. Auf den Hals 47 ist eine als Taste 51 dienende Kappe gesetzt, die mit einem Rastzylinder 53 den Hals 47 übergreift und in dessen Rastnut 55 überrastend eingreift. Zwischen der Taste 51 und dem Boden der Stufenbohrung 37 mit dem größeren Durchmesser stützt sich eine Druckfeder 49 ab. Diese ist vorgespannt und sucht den Rastbolzen 36 nach außen zu drücken, so daß sein Dichtungsbund 40 in Ruheposition dichtend an der Innenwand des Gehäuses 12 anliegt.In its upper region, the locking pin 36 on shoulders 45 in a neck 47 via. On the neck 47 serving as a button 51 cap is set, which engages over the neck 47 with a latching cylinder 53 and engages in the locking groove 55 latching. Between the key 51 and the bottom of the stepped bore 37 with the larger diameter, a compression spring 49 is supported. This is biased and seeks to push the locking pin 36 to the outside, so that its sealing collar 40 sealingly abuts the inner wall of the housing 12 in the rest position.

Der Rastbolzen 36 hat einen Betätigungshub zur Aktivierung des Spindelstops 34 von etwa 5 mm und greift dann mit seinem Zapfen 39 vollständig in eine der Vertiefungen 32 des Kegelrades 30 ein.The locking pin 36 has an actuating stroke for activating the spindle stop 34 of about 5 mm and then engages with its pin 39 completely in one of the recesses 32 of the bevel gear 30 a.

Das Durchmesser-Längen-Verhältnis des Sperrbolzens liegt zwischen 1,8 und 1,3. Dadurch ist gegenüber herkömmlichen Spindelstops die radiale Flächenpressung und die Belastung des Gehäuses 12 im Bereich der Schiebeführung 35 geringer.The diameter-length ratio of the locking pin is between 1.8 and 1.3. As a result, the radial surface pressure and the load of the housing 12 in the region of the sliding guide 35 are lower compared to conventional spindle stops.
