Description

Gegenstand der Erfindung ist ein Unwucht-Schwingungs-Erreger mit mehreren durch Zahnradgetriebe gekuppelten Unwuchten (z. B. Richterreger), bei dem mindestens ein Zahnräderpaar als Zahnradpumpe arbeitet.The invention relates to an unbalance vibration exciter with several imbalances coupled by gear drives (e.g. exciter) for which at least a pair of gears works as a gear pump.

Für große und mit hohen Umdrehungszahlen umlaufende, insbesondere sogenannte Überlagerungs-Unwucht-Schwingungs-Erreger, d.h. Erreger, bei denen die resultierende Erregungswirkung durch Überlagerung der Kraftkomponenten von zwei oder mehreren rotierenden Unwuchten entsteht, die vorzugsweise formschlüssig über Zahnräder miteinander gekuppelt sind, ist in vielen Fällen eine Druckölschmierung unerläßlich.For large and high revolving speeds, in particular so-called superimposition unbalance vibration exciters, i.e. exciters in which the resulting excitation effect by superimposing the force components of two or more rotating imbalances arises, which preferably form a positive fit Gears are coupled with one another, is in many cases a pressure oil lubrication indispensable.

Bislang verwendete man hierfür Zahnradpumpen, die getrennt vom Schwingungssystem angeordnet wurden und die die Lagerstellen im Erreger über elastische Leitungen versorgten. Solche Leitungen sind infolge ihrer doppelten Beanspruchung (innerer Überdruck, Schwingbeanspruchung) sehr störanfällig. Außerdem sind diese Leitungen oft relativ lang, so daß merkliche Reibungsverluste eintreten.So far, gear pumps have been used for this, which are separate from the vibration system were arranged and the bearing points in the exciter via elastic lines supplied. Due to their double stress (internal Overpressure, vibration stress) very susceptible to failure. Also, these are lines often relatively long, so that noticeable frictional losses occur.

Die Erfindung vermeidet diese Nachteile dadurch, daß das Kupplungsgetriebe des Überlagerungserregers selbst als Zahnradpumpe ausgebildet ist. Die Ölführung erfolgt hierbei in Kanälen, die im Erregergehäuse angebracht sind. Bei gegossenen Gehäusen können diese Kanäle auch eingegossen sein. Die Hauptstörungsquelle, nämlich die elastischen Druckleitungen, sind also vollständig vermieden, da nun die Olpumpe mitschwingt.The invention avoids these disadvantages in that the clutch transmission of the superimposition exciter itself is designed as a gear pump. The oil guide takes place in channels that are installed in the exciter housing. With cast These channels can also be cast in housings. The main source of interference, viz the elastic pressure lines are thus completely avoided, since now the oil pump resonates.

Als zusätzlicher Vorteil ergibt sich eine geringere Abnutzung und höhere Lebensdauer der Zahnräder, da der unter verhältnismäßig hohem Druck stehende Schmierfilm zwischen den Zahnflanken der hohen Schwingungsbeanspruchung und Korrosionsanfälligkeit der Getrieberäder besser gerecht wird als normale Schmierung.As an additional advantage, there is less wear and tear longer service life of the gears, as the one is under relatively high pressure Lubricant film between the tooth flanks of the high vibration stress and susceptibility to corrosion the gears better than normal lubrication.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar, und zwar Abb. r im Längsschnitt, Abb. z im Querschnitt.The drawing shows an embodiment of the invention, and Fig. r in longitudinal section, Fig. z in cross section.

Im Erregergehäuse i befinden sich die Lager a und 3 für die die Unwuchten 6, 611 bzw. 7, 7" tragenden Wellen 4 und 5. Die Unwuchtpaare 6, 611 und 7, 7" sind jeweils gleich groß, und ihre resultierende Kraftwirkung -ergibt eine Erregung in einer senkrecht zur Verbindungslinie der Wellenmitten 4 und 5 liegenden Geraden. Die Synchronisierung der beiden Wellen erfolgt durch ein Zahnradgetriebe 8 und 9, das zugleich als Zahnradpumpe wirksam ist.In the exciter housing i are the bearings a and 3 for the unbalance 6, 611 and 7, 7 "supporting shafts 4 and 5. The unbalance couples 6, 611 and 7, 7 'are each the same size, and their resultant force effect -ergibt excitation in a straight line perpendicular to the line connecting the shaft centers 4 and 5. The two shafts are synchronized by a gear mechanism 8 and 9, which also acts as a gear pump.

Das C51 wird vom Zahnrad 9 aus dem Ölsumpf 1a geschöpft und an der Eingriffsstelle E vom Gegenrad 8 in den Druckraum io gedrückt. Von da gelangt das Drucköl durch die Leitungen i i zu den Schmierstellen der Lager a und 3, von wo es durch die Rücklaufkanäle 13 in den Ölsumpf 1a zurückfließt.The C51 is scooped by the gear 9 from the oil sump 1a and attached to the Point of engagement E pressed by the mating gear 8 into the pressure chamber io. This is where it comes from Pressurized oil through lines i i to the lubrication points of bearings a and 3, from where it flows back through the return channels 13 into the oil sump 1a.
