Description
Der Zweck der Erfindung ist die Sicherstellung der Schmierung bei Gleitlagerungen von Planetenrädern.The purpose of the invention is to ensure lubrication in the case of sliding bearings of planet gears.
Es ist bekannt, solche Lager als Gleitlager unter Verwendung von Bronze als Gleitwerkstoff auszubilden und das in Planetengetrieben vorhandene Öl zur Schmierung dieser Gleitlager zu benutzen.It is known to design such bearings as slide bearings using bronze as the sliding material and to use the oil present in planetary gears to lubricate these slide bearings.
Es ist auch bekannt, knetverformte Zinnbronze mit etwa 8 bis 18 % Zinngehalt zu verwenden, weil solche Knetbronze bei einer Paarung mit Stahlgleitflächen, die in bester Weise gehärtet, geschliffen und poliert sind, die Möglichkeit zur Erreichung abnutzungsfrei arbeitender Gleitlager bringt.It is also known to use kneaded tin bronze with about 8 to 18% tin content, because such kneaded bronze, when paired with steel sliding surfaces that are hardened, ground and polished in the best way, enables wear-free sliding bearings to be achieved.
Die bekannten Gleitlager für Planetenräder haben den Nachteil, dass das Schmieröl in einer zu geringen Menge von Gleitflächen zugeführt wird. Es ist üblich, Radialbohrungen etwa in der radialen Mittelebene der Planetenräder vorzusehen, von denen das Öl, das von den Zahnflanken mitgenommen wird, bei der Drehbewegung zu den Gleitflächen gedrückt werden soll.The known sliding bearings for planetary gears have the disadvantage that too little of the lubricating oil is supplied from sliding surfaces. It is customary to provide radial bores approximately in the radial center plane of the planetary gears, from which the oil, which is carried along by the tooth flanks, is to be pressed towards the sliding surfaces during the rotary movement.
Durch die Fliehkräfte, die diesem Bestreben entgegenwirken, reicht die an sich schon ungenügende Ölmenge bei dieser Anordnung für eine zuverlässige Schmierung nicht aus.Due to the centrifugal forces that counteract this tendency, the already insufficient amount of oil in this arrangement is not sufficient for reliable lubrication.
Ein weiterer wesentlicher Nachteil der bekannten Konstruktionen liegt darin, dass die Planentenräder meist nur für eine kurze Zeit in das im Planetengetriebe vorhandene Ölbad eintauchen und den dabei aufgenommenen Ölfilz schnell verlieren.Another significant disadvantage of the known constructions is that the planetary gears are usually only immersed in the oil bath in the planetary gear for a short time and quickly lose the oil felt that is taken up in the process.
Wir haben uns die Aufgabe gestellt, diesen Mangel zu beseitigen und haben hierfür die folgende Lösung gefunden:We have set ourselves the task of eliminating this deficiency and have found the following solution:
Der Stahlbolzen, auf dem sich das Planetenrad dreht, wird mit einer durchgehenden Bohrung versehen.The steel bolt on which the planetary gear rotates is provided with a through hole.
Diese Bohrung wird durch eine oder mehrere Radialbohrungen mit der Außenfläche des Bolzens verbunden.This hole is connected to the outer surface of the bolt by one or more radial holes.
Dort, wo eine Radialbohrung auf der Bolzenoberfläche mündet, wird der Bolzen nahezu über die ganze Länge der Gleitfläche so stark abgeflacht, dass sich gegenüber der zylindrischen Bohrung der Lagerbüchse aus Knetbronze durch diese Abflachung ein Hohlraum bildet.Where a radial bore opens on the bolt surface, the bolt is flattened almost over the entire length of the sliding surface to such an extent that this flattening creates a cavity opposite the cylindrical bore of the wrought bronze bearing bush.
Münden mehrere Radialbohrungen auf der Bolzenoberfläche, dann werden an den betreffenden Stellen ebenfalls mehrere Abflachungen in gleicher Ausführung angeordnet.If several radial bores open out on the bolt surface, then several flattened areas of the same design are also arranged at the relevant points.
Das im Gehäuse vorhandene Öl kann also durch den hohlgebohrten Bolzen und durch jede Radialbohrung in den Hohlraum fließen, der durch die an der Mündung der Radialbohrung liegende Abflachung geschaffen worden ist. Von diesem Hohlraum aus, der die Wirkung einer Längsnut hat, wird im Gleitlager ein ausreichender Schmierfilm bei der Drehbewegung des Planetenrades gebildet.The oil present in the housing can therefore flow through the hollow-bored bolt and through each radial bore into the cavity that has been created by the flattened area at the mouth of the radial bore. From this cavity, which has the effect of a longitudinal groove, a sufficient lubricating film is formed in the plain bearing when the planetary gear rotates.
Um die Schmierung auch zu dem Zeitabschnitt zu sichern, der dann eintritt, wenn das Planetenrad das Ölbad verlassen hat, wird nach der vorliegenden Erfindung ein Schmierölvorrat im Hohlraum des durchbohrten Bolzens dadurch geschaffen, dass der Bolzen an den beiden Stirnseiten einen Randkragen erhält, beispielsweise durch je einen an der Stirnseite eingepressten Ring, dessen Innendurchmesser zwar so groß ist, dass beim Tauchvorgang genügend Öl in den im Bolzen vorhandenen Hohlraum einströmen kann, der aber den Durchmesser der im Bolzen vorhandenen Bohrung an den Stirnseiten so weit verengt, dass das eingeströmte Öl nur noch zu einem geringen Teil im folgenden Zeitabschnitt ausfließen kann.In order to ensure the lubrication also for the period of time that occurs when the planetary gear has left the oil bath, according to the present invention, a lubricating oil supply is created in the cavity of the pierced bolt in that the bolt is provided with an edge collar on both end faces, for example through One ring pressed in on the end face, the inner diameter of which is so large that sufficient oil can flow into the cavity in the bolt during the immersion process, but which narrows the diameter of the hole in the bolt on the end faces so much that the inflowing oil only can still flow out to a small extent in the following period.
Eine weitere Ölzuführung mit erschwertem Rückfluss wird durch ein radial in die zentrale Bolzenbohrung einmündendes, innen vorstehendes Röhrchen gegeben, das mit einer umlaufenden Ringwanne auf der Innenseite des Planetenrad-Tragringes durch eine gleichachsige Bohrung verbunden ist. In dieser Wanne sammelt sich Spritzöl, das durch das Röhrchen dem Bolzeninnenraum zugeführt wird.A further oil supply with more difficult backflow is provided by a tube protruding radially into the central pin bore, which is connected to a circumferential ring trough on the inside of the planetary gear support ring through a coaxial bore. In this trough, spray oil collects, which is fed through the tube to the interior of the bolt.
