Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Einrichtung zum selbsttätigen Auswuchten eines sich drehenden Maschinenteils, insbesondere bei einem handgeführten Arbeitsgerät, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for automatically balancing a rotating machine part, especially in a hand-held implement after the preamble of claim 1.

Auswuchteinrichtung der eingangs genannten Art ist beispielsweise
aus der
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum selbsttätigen Auswuchten eines sich drehenden Maschinenteils gegenüber dem Stand der Technik weiter zu verbessern.Of the Invention is based on the object, a device for automatic balancing a rotating machine part over the prior art on to improve.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Auswuchteinrichtung mit den Merkmalen des Anspruchs 1. Zum selbsttätigen Auswuchten eines sich drehenden Maschinenteils sind innerhalb einer die Rotationsachse des Maschinenteils umgebenden Unwuchtausgleichscheibe in einem ringförmigen Hohlraum freibewegliche Auswuchtmassen angeordnet, die eine eventuelle Unwucht durch Einnahme einer Gegenlage ausgleichen, wobei die Unwuchtausgleichscheibe aus zwei Halbschalen aufgebaut ist, welche – im Querschnitt betrachtet – mindestens eine in axiale Richtung verlaufende Trennebene aufweisen. Der ringförmige Hohlraum weist einen radial inneren und einen radial äußeren Teilraum auf, wobei in jedem Teilraum Auswuchtmassen, vorzugsweise gleicher Art, angeordnet sind.These The object is achieved by a balancing device with the features of claim 1. Zum automatic Balancing a rotating machine part are within one the axis of rotation of the machine part surrounding imbalance compensation disc in an annular Cavity free-wheel balancing mass arranged, which is an eventual Balance the imbalance by taking a counter bearing, with the imbalance compensation disc is constructed of two half-shells, which - viewed in cross-section - at least have a parting plane extending in the axial direction. The annular cavity has a radially inner and a radially outer subspace, wherein in each subspace balancing masses, preferably of the same kind arranged are.
Durch die zweireihige Anordnung von Auswuchtmassen ist die gesamte Unwuchtausgleichsmasse im Vergleich zu Auswuchteinrichtungen nach dem Stand der Technik wesentlich erhöht, wobei zugleich ein kompakter und fertigungstechnisch günstiger Aufbau gegeben ist. Die erfindungsgemäße Auswuchteinrichtung umfasst auch Ausführungsformen mit mehr als zwei Reihen von Auswuchtmassen. In jedem Fall ist bevorzugt mindestens eine der Halbschalen spanlos hergestellt. Es sind jedoch auch spanende Fertigungsverfahren zur Herstellung einer Halbschale der Unwuchtausgleichscheibe geeignet.By the two-row arrangement of balancing masses is the entire balancing mass compared to prior art balancing devices significantly increased, where at the same time a compact and manufacturing technology cheaper Structure is given. The balancing device according to the invention comprises also embodiments with more than two rows of balancing masses. In any case, it is preferred at least one of the half-shells produced without cutting. It is, however also machining production process for producing a half-shell the unbalance compensation disc suitable.
Sofern mindestens eine der Halbschalen durch spanlose Umformung gefertigt ist, ist eine dauerhafte Verbindung zwischen den Halbschalen beispielsweise durch Bördelung oder Verstemmung herstellbar.Provided at least one of the half-shells made by non-cutting forming is, is a permanent connection between the half shells, for example by crimping or caulking produced.
Die mindestens zwei Teilräume des ringförmigen Hohlraums sind in bevorzugter Ausgestaltung nicht vollständig voneinander getrennt. Vielmehr entspricht eine in axialer Richtung gemessene Öffnungshöhe zwischen den Teilräumen vorzugsweise mindestens der Hälfte, insbesondere mindestens 3/4, der Gesamthöhe des ringförmigen Hohlraums. Ein in den Hohlraum gefülltes Dämpfungsmittel, insbesondere Öl, kann sich somit frei in beiden bzw. allen Teilräumen verteilen, während die einzelnen Auswuchtmassen jeweils fest einem bestimmten Teilraum zugeordnet sind. Um die einzelnen Auswuchtmassen präzise in den jeweiligen Teilräumen zu führen, weist vorzugsweise eine der Halbschalen pro Teilraum eine rillenförmige Laufbahn auf. Derartige Laufbahnen können auch in der anderen Halbschale vorgesehen sein. Zur Führung der Auswuchtmassen ist es jedoch ausreichend, wenn nur eine der Halbschalen eine Rillenstruktur aufweist.The at least two subspaces of the annular Cavity are not completely separated from each other in a preferred embodiment separated. Rather corresponds to a measured opening height in the axial direction between the subspaces preferably at least half, in particular at least 3/4 of the total height of the annular cavity. One filled in the cavity Damping means especially oil, can thus be distributed freely in both or all subspaces, while the each balancing mass each fixed to a particular subspace assigned. To precisely fit the individual balancing masses the respective subspaces respectively, Preferably, one of the half shells per subspace has a groove-shaped track on. Such tracks can be provided in the other half-shell. To guide the Balancing masses, however, it is sufficient if only one of the half shells has a groove structure.
Die vorzugsweise kugelförmigen Auswuchtmassen sind beispielsweise aus Stahl gefertigt. Es sind jedoch auch Werkstoffe geringerer oder höherer Dichte als Stahl, zum Beispiel Blei, für die Herstellung der Auswuchtmassen geeignet. Eine Fertigung der Auswuchtmassen ist auch im Sinterverfahren möglich.The preferably spherical Balancing materials are made of steel, for example. There are but also materials of lower or higher density than steel, for Example lead, for the production of balancing masses suitable. A production of balancing masses is also possible in the sintering process.
