Abstract
Description
Die Erfindung betrifft einen Schwingungserreger, aufweisend ein Gehäuse mit drei darin zueinander parallel gelagerten und in Rotation versetzbaren Unwuchtwellen mit jeweiligen Unwuchtmassen, wobei die Unwuchtmassen eine Gesamtunwuchtmasse M bilden und die Mittelachsen der beiden äußeren Unwuchtwellen in einer Ebene liegen und parallel zu einer Aufstandsfläche des Schwingungserregers ausgerichtet sind und wobei die Mittelachse der mittleren Unwuchtwelle in gleichem Abstand zu den Mittelachsen der beiden äußeren Unwuchtwellen angeordnet ist.The The invention relates to a vibration exciter, comprising a housing with three parallel to each other and in rotation displaceable Unbalanced shafts with respective imbalance masses, wherein the imbalance masses form a total imbalance mass M and the center axes of the two outer unbalanced shafts lying in a plane and parallel to a footprint of the Vibration generator are aligned and wherein the central axis the middle imbalance wave equidistant from the central axes the two outer unbalanced shafts is arranged.

The content of this application is hereby incorporated by reference into the content of the present application made.
Derartige
Schwingungserreger werden auch als 3-Wellen-Erreger bezeichnet und
sind in der
Aufgabetask
Der Erfindung liegt entsprechend die Aufgabe zugrunde, einen Schwingungserreger zu schaffen, der durch seine Konstruktion unterschiedliches Lenk- und Vortriebsverhalten ermöglicht und/oder der die, insbesondere in Vortriebsrichtung wirkenden, Kippmomente des eingangs beschriebenen Schwingungserregers reduziert.Of the Invention is accordingly based on the object, a vibration generator which, due to its construction, has different steering and propulsion behavior allows and / or the, in particular acting in the direction of advance, tilting moments of the vibration generator described above reduced.
Lösungsolution
Ausgehend von dem eingangs genannten Schwingungserreger wird nach der Erfindung vorgeschlagen, dass die Unwuchtmasse der mittleren Unwuchtwelle von der Hälfte der Gesamtunwuchtmasse um mindestens 10%, vorzugsweise um mindestens 20%, abweicht.outgoing of the vibration generator mentioned above is according to the invention suggested that the imbalance mass of the central unbalanced shaft from the half the total imbalance mass by at least 10%, preferably by at least 20%, differs.
Durch eine Massenverteilung, die von der bisherigen Masseverteilung von M/4 : M/2 : M/4 abweicht, kann das Schwingungserreger in seiner Lenkbarkeit träger oder sensibler konzipiert werden. Auch der Vortrieb kann mehr oder weniger stark ausgelegt werden. Beispielhaft können die folgenden vorteilhaften Massenverteilungen gewählt werden: 22,5 : 55 : 22,5 (10% Abweichung der mittleren Unwuchtmasse) 20 : 60 : 20 (20% Abweichung), 15 : 70 : 15 (30% Abweichung), 35 : 30 : 35 (40% Abweichung), 30 : 40 : 30 (20% Abweichung).By a mass distribution that differs from the previous mass distribution of M / 4: M / 2: M / 4 deviates, the vibration exciter can in its steerability carrier or more sensitive. Also the propulsion can be more or be designed less strong. By way of example, the following may be advantageous Mass distributions selected are: 22.5: 55: 22.5 (10% deviation of the average imbalance mass) 20: 60: 20 (20% deviation), 15: 70: 15 (30% deviation), 35 : 30: 35 (40% deviation), 30: 40: 30 (20% deviation).
Insbesondere ist es vorteilhaft, dass die Unwuchtmasse der mittleren Unwuchtwelle um mindestens 10% größer ist, als die Hälfte der Gesamtunwuchtmasse und in Umfangsrichtung der Unwuchtwelle gegenüber den äußeren Unwuchtwellen verschwenkbar ist.Especially It is advantageous that the imbalance mass of the central unbalanced shaft is at least 10% larger, than half the total imbalance mass and in the circumferential direction of the imbalance shaft against the outer unbalanced shafts is pivotable.
Die
Verschwenkbarkeit ist bereits in der
Eine Lösung der Aufgabe besteht zudem darin, auf die symmetrische Verteilung der äußeren Unwuchtmassen zu verzichten, etwa dadurch, dass die Unwucht der beiden äußeren Unwuchtwellen voneinander um mindestens 5%, vorzugsweise um mindestens 10%, der Gesamtunwuchtmasse (M) abweichen, also etwa Massenverhältnisse von 20 : 55 : 25 (5% Abweichung der beiden äußeren Unwuchmassen) oder 20 : 30 : 50 (60% Abweichung) gewählt sind. Es ist bekanntermaßen nachteilig, dass bei einem Vorwärtsvortrieb die Grundplatte des Schwingungserregers mit einer Massenverteilung nach dem Stand der Technik eine Art leichte Bugwelle, bestehend aus dem zu verdichtenden Material, vor sich herschiebt. Durch die erfindungsgemäße Massenverteilung kann die beschriebene Bugwelle vermieden werden, indem die Schwingungsamplitude des Erregers im vorderen Teil durch Erhöhung der Unwuchtmasse der vorderen Unwuchtwelle gegenüber der hinteren Unwuchtwelle erhöht wird. Eine Masseverteilung zwischen der vorderen und der hinteren Unwuchtwelle mit 10% Abweichung, etwa 30 : 50 : 20, ist in diesem Fall vorteilhaft gewählt, da das Steig- und Vortriebsverhalten mit dieser Verteilung besonders verbessert ist, ohne das Verdichtungsverhalten ansonsten nachteilig zu beeinflussen. Der Vorteil der unsymmetrischen Konstruktion ist selbstverständlich auch auf 2-Wellenerreger übertragbar.A solution to the problem is also to dispense with the symmetrical distribution of the outer imbalance masses, such as the fact that the imbalance of the two outer unbalanced shafts differ from each other by at least 5%, preferably at least 10%, the total imbalance mass (M), ie about mass ratios of 20: 55: 25 (5% deviation of the two external imbalances) or 20: 30: 50 (60% deviation) are selected. It is known disadvantageous that in a forward propulsion the base plate of the vibration generator with a mass distribution according to the prior art, a kind of slight bow wave, consisting of the material to be compacted, pushes in front of him. Due to the mass distribution according to the invention, the bow wave described can be avoided by the vibration amplitude of the exciter is increased in the front part by increasing the imbalance mass of the front imbalance shaft relative to the rear imbalance shaft. A mass distribution between the front and the rear unbalanced shaft with 10% deviation, about 30: 50: 20, is chosen in this case advantageous because the climbing and propulsion behavior with this distribution is particularly improved without otherwise adversely affecting the compression behavior. The advantage of the asymmetrical design is of course also applicable to 2-wave exciters.
Die Aufgabe der Erfindung wird ferner auch dadurch gelöst, dass sich die Mittelachse der mittleren Unwuchtwelle mit einem Versatz zu der von den beiden Mittelachsen der äußeren Unwuchtwellen aufgespannten Ebene erstreckt. Der Höhenversatz kann zu der Aufstandsfläche hin oder von dieser weg bestehen.The The object of the invention is also solved by the fact that the central axis of the central imbalance shaft with an offset to the spanned by the two central axes of the outer unbalanced shafts Plane extends. The height offset can to the footprint out or away from it.
Eine Ausgestaltung der Erfindung soll schließlich darin bestehen, dass Mittelachse der mittleren Unwuchtwelle gegenüber der von den beiden Mittelachsen der äußeren Unwuchtwellen aufgespannten Ebene in Richtung auf die von der Aufstandsfläche der Vibrationsplatte gebildeten Ebene versetzt ist, um den Schwerpunkt des Schwingungserregers tiefer zu legen, was grundsätzlich von Vorteil ist. Zudem können durch die erfindungsgemäße Verlagerung der mittleren Unwuchtwelle, die Abstände zwischen der mittleren und den beiden äußeren Unwuchtwellen reduziert werden, wodurch der Schwingungserreger entsprechend kleiner gebaut werden kann.A Embodiment of the invention should finally consist in that Central axis of the central imbalance shaft opposite to that of the two central axes the outer imbalance waves plane in the direction of the footprint of the plane Vibrating plate formed plane is offset to the center of gravity lower the vibration exciter, which is basically of Advantage is. In addition, you can by the displacement according to the invention the middle imbalance wave, the distances between the middle imbalance and the two outer unbalanced shafts be reduced, causing the vibration generator correspondingly smaller can be built.
Weitere vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous developments of the invention are the dependent claims remove.
