Abstract
Description
Die vorliegende Erfindung betrifft eine Getriebeanordnung für ein Arbeitsgerät nach der im Oberbe griff des Anspruchs 1 angegebenen Art.The present invention relates to a gear arrangement for an implement according to the Oberbe handle of claim 1 specified type.
Handgeführte Arbeitsgeräte wie Trennschleifer, Lochbohrer, Freischneider, Bohrhämmer oder Motorkettensägen usw. werden in vielen Ausführungsformen und in großen Stückzahlen herge stellt.Hand-held tools such as cutters, hole drills, brush cutters, rotary hammers or chainsaws etc. are available in many designs and in large quantities poses.
Hierbei ist es insbesondere von großer sicherheitstechnischer Bedeutung (Z. B. bei einer Werkzeugblockade) und zur Erzielung guter Arbeitsergebnisse wichtig, daß das Werkzeug des Ar beitsgerätes vom Anwender möglichst ruhig, punktgenau und mit wenig Kraftaufwand am Werkstück geführt werden kann. Bei den bisherigen Arbeitsgeräten dieser Art ist dies, insbesondere z. B. bei Trennschleifern und Lochbohrern, nur schwierig zu erreichen, da das entsprechende Werkzeug mit zumeist hoher Umfangsgeschwindigkeit und nur in einer Richtung drehend mit relativ großen Kräften am Werkstück geführt werden muß. Darüberhinaus ist es von praktischer Bedeutung, wenn ein Ar beitsgerät für mehrere Funktionen eingesetzt werden kann.It is particularly important in terms of safety technology (e.g. for a Tool block) and to achieve good work results it is important that the tool of the Ar user tool as quietly as possible, precisely and with little effort on the workpiece can be performed. With previous tools of this type, this is particularly the case for. B. at Cut-off machines and hole drills, difficult to reach because the appropriate tool is used mostly high peripheral speed and only rotating in one direction with relatively large forces must be guided on the workpiece. Furthermore, it is of practical importance if an Ar Beitsgerät can be used for multiple functions.
Ziel der Erfindung ist die Schaffung einer Getriebeanordnung, die die einseitig wirkenden Kräfte des Werkzeugs am Werkstück durch entsprechende Gegenkräfte aufhebt und bei Bedarf als Multifunktions-Arbeitsgerät eingesetzt werden kann.The aim of the invention is to provide a gear arrangement which is single-acting Forces of the tool on the workpiece can be counteracted by appropriate counterforces and, if necessary, as Multi-function implement can be used.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß eine Getriebeanordnung zum Ein satz kommt, die es ermöglicht, daß zwei geringfügig zueinander beabstandete Werkzeuge mit dem selben - oder nahezu demselben Durchmesser - mit gleicher Umfangsgeschwindigkeit jeweils in ent gegengesetzter Richtung drehen. Die Getriebeanordnung läßt darüber hinaus auch noch einen alter nativen Einsatz als Bohrhammer zu.According to the invention, this object is achieved in that a gear arrangement for one comes set that allows two slightly spaced tools with the same - or almost the same diameter - with the same peripheral speed each in ent turn in the opposite direction. The gear arrangement also leaves an old one native use as a hammer drill too.
Vorteilhafte Weiterbildungen der Erfindung sind durch die von diesem Anspruch abhängigen Unteransprüche gekennzeichnet.Advantageous developments of the invention are dependent on this claim Subclaims marked.
In folgendem wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit drei Zeichnungen beschrieben. Dabei zeigtIn the following the invention based on a preferred embodiment in conjunction with described three drawings. It shows
Fig. 1 eine vereinfachte Schnittzeichnung in Seitenansicht. Die Motorwelle (23) oder die Getriebe welle treibt über das Kegelritzel (26) die gegenläufigen Kegelzahnräder (9, 34) und die wiederum das Kegelritzel (6). Die Gegenläufigkeit der Kegelzahnräder wird dazu genutzt die, zueinander plan verlaufenden Werkzeuge wie z. B. die Lochbohrer (11, 12) oder die Trennscheiben (60, 61) am Werkstück ohne viel Druck und Positionierungsarbeit anzusetzen, da sich die Werkzeugkräfte aufhe ben. Dies ist auch von großer sicherheitstechnischer Bedeutung, da bei einer plötzlichen Blockade des Werkzeugs im Werkstück keine schädigenden Kräfte auf den Anwender übergehen! Die Kegel zahnradachse (15) kann auch noch dazu genutzt werden, eine weitere Kupplungsvorrichtung (41) anzubringen. Um auch einen Einsatz als Bohrhammer zu nutzen, ist die Kegelzahnradachse (15) mit dem Hohlkolbennocken (28) versehen auf dem der Hohlkolben (8) in der Bohrkammerspindel (32) läuft. Der Hohlkolben (8), in dem der Schlagkörper (5) läuft, wird durch die Druckfeder (33), die den Zwischendöpper (4) als Widerlager nutzt, immer wieder gegen den Hohlkolbennocken (28) gedrückt. Bei Bedarf kann die Druckfeder (33) auch mechanisch entkoppelt vom Zwischendöpper (4) laufen, indem ein Widerlager hierfür in die Bohrkammerspindel (32) gearbeitet wird. Fig. 1 is a simplified sectional drawing in side view. The motor shaft ( 23 ) or the gear shaft drives the conical pinion gears ( 9 , 34 ) via the bevel pinion ( 26 ) and in turn the bevel pinion ( 6 ). The counter-rotation of the bevel gears is used to the tools that run flat to each other, such as. B. the hole drills ( 11 , 12 ) or the cutting discs ( 60 , 61 ) on the workpiece without much pressure and positioning work, because the tool forces. This is also of great importance in terms of safety, since if the tool is suddenly blocked in the workpiece, no damaging forces are transferred to the user! The bevel gear axis ( 15 ) can also be used to attach a further coupling device ( 41 ). In order to use it as a rotary hammer, the bevel gear axis ( 15 ) is provided with the hollow piston cam ( 28 ) on which the hollow piston ( 8 ) runs in the drilling chamber spindle ( 32 ). The hollow piston ( 8 ), in which the impact body ( 5 ) runs, is repeatedly pressed against the hollow piston cam ( 28 ) by the compression spring ( 33 ), which uses the intermediate striker ( 4 ) as an abutment. If required, the compression spring ( 33 ) can also run mechanically decoupled from the intermediate striker ( 4 ) by working an abutment for this purpose in the drilling chamber spindle ( 32 ).
Fig. 2 zeigt den Schnitt A. Der Entlüftungskanal (37) steht über die Entlüftungsöffnung (56) mit dem Entlüftungsstutzen (50) und der Entlüftungsbohrung (53) in Strömungsverbindung. Über die Entlüftungsrändel (52) kann zum Stoppen der Bohrhammerfunktion der Raum im Bereich der Druckfeder (33) dosiert entlüftet werden, was auch zur Anschlagskraftveränderung des Schlagkör pers (5) auf den Zwischendöpper (4) genutzt werden kann. Zur Erhöhung der Schlagfrequenz kann der Hohlkolbennocken (28) auch eine um 120° oder höher versetzte Nockenkurve (54) aufweisen. Fig. 2 shows the section A. The ventilation channel ( 37 ) is in flow connection via the ventilation opening ( 56 ) with the ventilation nozzle ( 50 ) and the ventilation bore ( 53 ). About the vent knurl ( 52 ) to stop the hammer drill function, the space in the area of the compression spring ( 33 ) can be vented in doses, which can also be used to change the impact force of the percussion body ( 5 ) on the intermediate striker ( 4 ). To increase the stroke frequency, the hollow piston cam ( 28 ) can also have a cam curve ( 54 ) offset by 120 ° or higher.
Fig. 3 zeigt eine Anordnung von Trennscheiben (60), die die Lochbohrer (11, 12) ersetzen können. Fig. 3 shows an arrangement of cutting discs ( 60 ) which can replace the hole drills ( 11 , 12 ).
