Description
Zapfwelle, insbesondere für Ackerschlepper Die Erfindung bezieht sich auf eine Zapfwelle, insbesondere für Ackerschlepper, die aus einem Getriebegehäuse herausragt, in dem in der Richtung der Längsmittelachse der Zapfwelle mehrere hintereinanderliegende, mit verschiedenen Drehzahlen angetriebene Kupplungsglieder vorgesehen sind.Power take-off shaft, especially for farm tractors The invention relates to on a power take-off shaft, especially for agricultural tractors, consisting of a gearbox protrudes, in which in the direction of the longitudinal center axis of the PTO several consecutive, Coupling members driven at different speeds are provided.
Es sind Zapfwellen bei Ackerschleppern bekanntgeworden, bei denen zwischen dem Antriebsmotor und der Zapfwelle nur eine einzige Untersetzung vorgesehen ist, so daß die Zapfwelle nur auf der Grundlage dieser Untersetzung bei Höchstdrehzahl des Antriebsmotors mit einer genormten Drehzahl von n=450 U/min umläuft. Diese Zapfwellen, die für angehängte bzw. angebaute Geräte mit niedrigen Antriebsleistungen entwickelt worden waren, wurden zur Verbilligung der übertragung von höheren Leistungen durch Zapfwellen ergänzt bzw. abgelöst, die gleichfalls nur einer einzigen Untersetzung zum Antriebsmotor hin unterliegen, jedoch bei Höchstdrehzahl des Antriebsmotors mit einer Drehzahl von n=1000U/min umlaufen. Dabei ist vorgesehen, daß die Zapfwelle zur Vermeidung von Verwechslungen mit einem besonders ausgebildeten Kuppelglied versehen ist.Power take-offs have become known in agricultural tractors where only a single reduction is provided between the drive motor and the PTO shaft is so that the PTO only based on this reduction at maximum speed of the drive motor rotates at a standardized speed of n = 450 rpm. These PTOs, Developed for attached or built-on devices with low drive power had been, were made to cheapen the transmission of higher benefits through PTOs supplemented or replaced, which also only have a single reduction towards the drive motor, but at the maximum speed of the drive motor rotate at a speed of n = 1000 rpm. It is provided that the PTO shaft to avoid confusion with a specially designed coupling element is provided.
Um mit einem Schlepper sowohl die noch vorhandenen Geräte, die für eine Antriebsdrehzahl von n=540 U/min ausgelegt sind, sowie Geräte für eine Antriebsdrehzahl von n=1000 U/min antreiben zu können, ging man dazu über, am Schlepper zwei Zapfwellen vorzusehen, die vom Antriebsmotor aus über unterschiedliche, auf die beiden Zapfwellendrehzahlen von n=540 U/min sowie n=1000 U/min abgestimmte Untersetzungen angetrieben wurden. Da für die Zapfwelle am Schlepper eine bestimmte Stelle erwünscht ist, lag somit der Nachteil vor, daß nur eine der beiden Zapfwellen an dieser Stelle sitzen konnte und zudem die jeweils nicht benutzte Zapfwelle gegen Berührung und Verschmutzung auch noch zu schützen war.In order to use a tractor to carry out both the remaining devices that are used for a drive speed of n = 540 rpm are designed, as well as devices for a drive speed To be able to drive from n = 1000 rpm, one went over to having two power take-offs on the tractor to be provided, which from the drive motor on different, on the two PTO shaft speeds of n = 540 U / min as well as n = 1000 U / min coordinated reductions were driven. Since a certain point is required for the PTO shaft on the tractor, was therefore the disadvantage that only one of the two PTO shafts could sit at this point and also the unused PTO against contact and contamination also had to be protected.
Um diese Nachteile zu vermeiden, hat man in verschiedenen Fällen einer einzigen Zapfwelle ein Schaltgetriebe vorgeordnet. Ein solches Schaltgetriebe erfüllt natürlich alle Anforderungen hinsichtlich der gewünschten Drehzahlen und der Anordnung der Zapfwelle. Ein Schaltgetriebe bedeutet aber noch einen größeren Aufwand als er für die vorbeschriebenen zwei Zapfwellen nötig ist. Eine einzige auf zwei Drehzahlen umschaltbare Zapfwelle hatte jedoch weiterhin noch den Nachteil, daß das kupplungsseitige Ende des Zapfwellenstummels nur ein Kupplungsglied aufwies, das entweder dem für die Zapfwellendrehzahl von n=540 U/min oder dem von n=1000 U/min genormten entsprach.In order to avoid these disadvantages, one has one in various cases single PTO shaft upstream of a manual gearbox. Such a manual transmission met of course, all requirements with regard to the desired speeds and the arrangement the PTO. But a manual transmission means even more effort than it is necessary for the two PTO shafts described above. A single at two speeds switchable PTO still had the disadvantage that the clutch-side The end of the PTO stub had only one coupling member that was either the one for the PTO speed of n = 540 rpm or that of n = 1000 rpm was standardized.
Zur Vermeidung dieses Nachteils ist es bei einer Zapfwelle mit Schaltgetriebe bekanntgeworden, zwei austauschbare Stummel vorzusehen, deren einer ein Kuppelglied für die Antriebsdrehzahl von n=540 U/min und deren anderer ein Kuppelglied für n=1000 U/min aufweist. Dies bedeutet jedoch einen weiteren wesentlichen Mehraufwand und zudem den Nachteil eines leicht verlierbaren Losteils.To avoid this disadvantage, it is a PTO with a manual gearbox has become known to provide two interchangeable stubs, one of which is a coupling element for the drive speed of n = 540 rpm and the other one a coupling element for n = 1000 RPM. However, this means a further significant additional expense and also the disadvantage of an easily lost loose part.
Die Erfindung bezweckt eine einfache und in jeder Beziehung zufriedenstellende Lösung für eine Zapfwelle zu schaffen. Dabei soll vor allem sichergestellt sein, daß für die entsprechende Normdrehzahl jeweils nur das entsprechende Zapfwellennormprofil als Gegenkuppelglied aus Sicherheitsgründen zur Verfügung steht.The invention aims to be simple and satisfactory in every respect To create a solution for a PTO shaft. Above all, it should be ensured that that for the corresponding standard speed only the corresponding PTO standard profile is available as a mating coupling element for safety reasons.
Diese Aufgabe wird im wesentlichen dadurch gelöst, daß die Zapfwelle umsteckbar ist und in jeder ihrer beiden möglichen Stellungen je mit einem der Kupplungsglieder kuppelbar ist.This object is essentially achieved in that the power take-off shaft is reversible and in each of its two possible positions with one of the coupling members can be coupled.
Hierbei ist es zweckmäßig, wenn die Zapfwelle ein umsteckbarer Zapfen ist, der im Bereich seiner Längsmitte einen Anschlag hat und daß den jeweiligen Kupplungsgliedern entsprechend Gegenkuppelglieder an der Zapfwelle einen verschieden großen Abstand von dem Anschlag haben, derart, daß im Durchmesser kleinere Gegenkuppelglieder einen größeren Abstand von dem Anschlag haben als auf der anderen Zapfenseite vorgesehene Gegenkuppelglieder größeren Durchmessers und entsprechend die im Getriebegehäuse angeordneten Kupplungsglieder mit wachsendem Abstand von dem an dem Getriebegehäuse vorgesehenen Gegenanschlag für den Anschlag der Zapfwelle kleiner werden.It is useful here if the power take-off shaft is a reversible pin is, which has a stop in the region of its longitudinal center and that the respective Coupling members according to mating coupling members on the PTO one different have a large distance from the stop, such that mating coupling elements smaller in diameter have a greater distance from the stop than provided on the other side of the pin Counter-coupling elements of larger diameter and correspondingly those in the gear housing arranged coupling members with increasing distance from that on the transmission housing provided counter-stop for the stop of the PTO shaft become smaller.
Von Vorteil ist es, wenn der Anschlag an der Zapfwelle ein die Zapfwelle umgebendes und in Richtung der Längsmittelachse der Zapfwelle auf dieser festgelegtes Wälzlager ist, welches von einem bundartigen Gehäuse umgeben ist, das auf seinen beiden Seiten als Anschlag dient und mit einem Schnellanschluß am Schleppergetriebegehäuse befestigt ist. Zur Vermeidung von Unfällen ist es dabei vorteilhaft, daß die Kupplungsglieder und Gegenkuppelglieder Wellenverzahnungen sind, deren Verzahnung den Zapfwellennormprofilen entspricht.It is advantageous if the stop on the power take-off shaft is a power take-off shaft surrounding and fixed in the direction of the longitudinal center axis of the PTO shaft on this Rolling bearing is that of a collar-like Housing is surrounded, which serves as a stop on both sides and with a quick connector on the Tractor gearbox is attached. It is included to avoid accidents advantageous that the coupling members and mating coupling members shaft teeth whose toothing corresponds to the PTO standard profiles.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Stecköffnung für die Zapfwelle an ihrem getriebeseitigen Ende öldicht verschlossen ist.In a further embodiment of the invention it is provided that the plug-in opening for the PTO is closed oil-tight at its end on the transmission side.
In der Zeichnung ist eine Ausführungsform der Erfindung in zwei Abbildungen beispielsweise dargestellt.In the drawing is an embodiment of the invention in two figures for example shown.
Die A b b. 1 und 2 zeigen senkrechte Längsschnitte durch den hinteren Teil eines Schleppergetriebes, aus dem die Zapfwelle herausragt.The A b b. 1 and 2 show vertical longitudinal sections through the rear Part of a tractor transmission from which the PTO protrudes.
In A b b. 1 ist in einem Getriebegehäuse 1 eine Antriebswelle 2 gelagert, die zwei Zahnräder 3 und 4 aufweist. Die Zahnräder 3 und 4 treiben zwei hintereinanderliegende, parallel zur Längsmittelachse der Antriebswelle 2 angeordnete Zahnräder 5 bzw. 6 an, die hülsenförmige Fortsätze 7 bzw. 8 aufweisen, mittels deren sie über ein normales Kugellager 9 bzw. ein in sich abgedichtetes Kugellager 10 im Getriebegehäuse 1 gelagert sind. Das Zahnrad 6 ist weiterhin mit einem hülsenförmigen Fortsatz 11 versehen, der in einem Nadellager 12 und einem Abdichtring 13 steckt, die innerhalb des Zahnrades 5 und dessen hülsenförmigem Fortsatz 7 angeordnet sind. Die hülsenförmigen Fortsätze 7 bzw. 8 sind mit keilwellenverzahnten Koppelgliedern 14 bzw. 15 versehen.In A b b. 1, a drive shaft 2 , which has two gear wheels 3 and 4 , is mounted in a gear housing 1. The gears 3 and 4 drive two gearwheels 5 and 6 , one behind the other, which are arranged parallel to the longitudinal center axis of the drive shaft 2 and which have sleeve-shaped extensions 7 and 8, by means of which they can be connected to a normal ball bearing 9 or a sealed ball bearing 10 in the transmission housing 1 are stored. The gear 6 is also provided with a sleeve-shaped extension 11 which is inserted in a needle bearing 12 and a sealing ring 13, which are arranged within the gear 5 and its sleeve-shaped extension 7. The sleeve-shaped extensions 7 and 8 are provided with splined coupling members 14 and 15 , respectively.
Das Koppelglied 14, das mittels eines Deckels 16 vom Getriebegehäuse 1 öldicht abgeschlossen ist, umgibt einen Wellenstummel 17 einer Zapfwelle 18, die mit keilwellenverzahnten Gegenkuppelgliedern 19, 20 und 21 versehen ist, wovon das Gegenkuppelglied 19 mit dem Koppelglied 14 im Eingriff steht.The coupling member 14, which is sealed oil-tight from the transmission housing 1 by means of a cover 16 , surrounds a shaft stub 17 of a power take-off shaft 18 which is provided with splined coupling members 19, 20 and 21 , of which the counter coupling member 19 is in engagement with the coupling member 14.
Die Zapfwelle 18 ist in einem im hülsenförmigen Fortsatz 11 angeordneten Ring 22 und einem in sich abgedichteten Kugellager 23 gelagert, das von einem bundartigen Gehäuse 24 umschlossen wird, welches mittels eines nicht dargestellten Schnellanschlusses mit dem Getriebegehäuse 1 verspannt ist. Das Kugellager 23 ist durch einen Springring 25 und das Gegenkuppelglied 20 axial zur Zapfwelle 18 und mittels eines Bundes 26 des Gehäuses 24, einer Scheibe 27 und eines Springringes 28 axial zum Gehäuse 24 festgesetzt.The power take-off shaft 18 is mounted in a ring 22 arranged in the sleeve-shaped extension 11 and in a sealed ball bearing 23 which is enclosed by a collar-like housing 24 which is clamped to the gear housing 1 by means of a quick connector (not shown). The ball bearing 23 is fixed axially to the power take-off shaft 18 by a spring ring 25 and the mating coupling element 20 and axially to the housing 24 by means of a collar 26 of the housing 24, a disk 27 and a spring ring 28.
Soll, wie in A b b. 2 dargestellt, an Stelle des Koppelgliedes 14 das Koppelglied 15 mit dem Gegenkuppelglied 20 der Zapfwelle 18 gekuppelt und damit diese über die Zahnräder 4 und 6 angetrieben werden, so wird mittels des nicht dargestellten Schnellanschlusses das bundartige Gehäuse 24 vom Getriebegehäuse 1 gelöst, die Zapfwelle 18 mitsamt dem aufsitzenden Kugellager 23 und dem Gehäuse 24 gedreht und durch Einstecken das Gegenkuppelglied 20 mit dem Koppelglied 15 gekuppelt. Hiernach wird mittels des Schnellanschlusses das bundartige Gehäuse 24 wiederum mit dem Getriebegehäuse 1 verspannt, so daß kurzmöglichst eine Untersetzungsänderung mit gleichzeitiger Bereitstellung des dieser zugeordneten Koppelgliedes für die Zapfwelle 18 geschaffen ist.Should, as in A b b. 2, instead of the coupling member 14, the coupling member 15 is coupled to the mating coupling member 20 of the power take-off shaft 18 and so that these are driven via the gears 4 and 6 , the collar-like housing 24 is detached from the gear housing 1, the power take-off shaft 18, by means of the quick connection (not shown) rotated together with the seated ball bearing 23 and the housing 24 and the mating coupling member 20 is coupled to the coupling member 15 by insertion. After this, the collar-like housing 24 is again clamped to the gear housing 1 by means of the quick connection, so that a reduction in the reduction ratio is created as quickly as possible with simultaneous provision of the coupling element assigned to this for the power take-off shaft 18 .
