Abstract

To apply a defined shift in the pretension on the bearings for a shaft or axis in at least two bearings at an angle, in a X- or O-array, the shaft is prepared for a hydraulic installation in the inner ring seating of a bearing (2) with axial drillings (5) for the hydraulic pressure supply to the fitting joint, and a ring groove (3). The radial drilling (4) between the ring groove and the axial drillings has a diameter to take at least 1.5 times the ring groove volume. The separating piston (6) is moved from the ring groove side to the lateral drilling, which is filled with an adhesive fluid. The bearings (1,2) have been cleaned in advance of any oil or grease, and the inner ring is heated for installation to prevent shaft surface damage. The hydraulic pressure is increased according to the over-dimensioned fit and the inner ring wall thickness, and the adhesive fluid is pressed into the fitting joint.

Description

Anwendungsgebietfield of use

Die Anwendung von spielfreien oder vorgespannten Schräglagern, in X- oder O- Anordnung verbaut, zur Aufnahme von Radial- und Axiallasten sowie steifen Wellenlagerungen, ist weit verbreitet, z. B. in Getrieben, Axialkolbenpumpen, Walzen, Spindeln, Rotoren, Radlagern und dgl. The use of backlash-free or preloaded angular bearings, in X- or O- Arrangement installed, for absorbing radial and axial loads as well as stiff Shaft bearings is widely used, e.g. B. in gearboxes, axial piston pumps, Rollers, spindles, rotors, wheel bearings and the like

Stand der TechnikState of the art

Unter Schräglagern versteht man im allgemeinen Schrägkugellager, Spindellager, Vierpunktlager, Kegelrollen- und Schrägrollenlager. Angular contact bearings are generally understood to be angular contact ball bearings, spindle bearings, Four point bearings, tapered roller and angular roller bearings.

Für diese Lagerungsart, die meist in IX- oder O-Anordnung vorgesehen wird, ist eine individuelle axiale Einstellung eines Lagerspieles oder -vospannung mit nachfolgender Fixierung des eingestellten Spiel- oder Vorspannungswertes notwendig. Die axiale Fixierung erfolgt je nach X- oder O-Anordnung meist mittels einer Wellenmutter, Achskappe oder über Gehäusedeckel. For this type of storage, which is usually provided in IX or O arrangement, there is one individual axial adjustment of a bearing play or preload with subsequent fixation of the set backlash or preload value necessary. Depending on the X or O arrangement, the axial fixation is usually carried out by means of a Shaft nut, axle cap or over the housing cover.

Die Spieleinstellung kann erfolgen:

  • a) durch Vorabstimmung der Lagerringe seitens des Lagerherstellers mit anschließender axialer Verspannung der Ringe durch eine Wellenmutter oder Gehäusedeckel.
  • b) durch abgepasste Distanzringe die jeweils zwischen den Innenringen und Außenringen positioniert werden und anschließend durch eine Wellenmutter und Gehäusedeckel axial verspannt werden.
  • c) durch Überstandsvermessung und Anpassen mittels Pass-Scheiben bei der Montage.
  • d) durch kontrolliertes Anziehen einer Wellenmutter oder Gehäusedeckels bei gleichzeitiger Reibmoment- oder Axialspielmessung.
The game setting can be done:
  • a) by pre-coordination of the bearing rings on the part of the bearing manufacturer with subsequent axial bracing of the rings by means of a shaft nut or housing cover.
  • b) by means of spacer rings which are positioned between the inner rings and outer rings and are then axially clamped by a shaft nut and housing cover.
  • c) by measuring the protrusion and adjusting it using shims during assembly.
  • d) by controlled tightening of a shaft nut or housing cover with simultaneous measurement of friction torque or axial play.

Im überwiegenden Teil ist der Einstellvorgang an dem Lagerring durchzuführen der gemäß der Umfangslastbestimmung stramm, d. h. mit Passungsübermaß montiert werden muss. In den Fällen a) b) und c) bereitet das kaum Schwierigkeiten. Allerdings gestalten sich diese Lagerungen relativ unwirtschaftlich durch die im Vorfeld zu treffenden aufwendigen Abpassmaßnahmen. For the most part, the adjustment process is carried out on the bearing ring tight according to the peripheral load determination, d. H. fitted with fit oversize must become. In cases a) b) and c) this is hardly a problem. Indeed these bearings are relatively uneconomical due to the in advance appropriate elaborate fitting measures.

Im Fall c) kann mit preisgünstigen Standardlagern gearbeitet werden. Das meist vorliegende Passungsübermaß des anzustellenden Ringes erschwert die Axialspieleinstellung erheblich. Einen Kompromiss stellt die Reduzierung des Passungsübermaßes bis auf 0 oder Passungsspiel dar. Hier sind Verschleißprobleme je nach Umfanglastbestimmung zwischen Innenring und Welle bzw. Außenring und Gehäuse, fehlende Steifigkeit oder ungenügende Genauigkeit am Lagersystem zu erwarten. Zum anderen stellen sich Setzeffekte der Gewindeelemente ein, da diese nicht mit dem erforderlichen Anzugsmoment montiert werden können. In case c) you can work with inexpensive standard bearings. Most of the time Existing fit excess of the ring to be started complicates the Axial play setting considerably. The reduction of the Excess fit down to 0 or fit clearance. Here there are wear problems each after determining the circumferential load between inner ring and shaft or outer ring and Housing, lack of rigidity or insufficient accuracy on the bearing system expect. On the other hand, there are set effects of the threaded elements, since these cannot be installed with the required tightening torque.

Gewindeelemente können Wellenmuttern und Schrauben für Achskappen oder Gehäusedeckelbefestigungen sein. Threaded elements can be shaft nuts and screws for axle caps or Be housing cover fastenings.

Unter Betriebslast entstehen bei Schräglagern Axialkräfte, die bei den jeweiligen Gewindeelementen zu einem "Setzen" des Gewindes und damit zu einer zwangsläufigen Veränderung des Anfangs eingestellten Axialspieles- oder Vorspannungswertes am Lagersystem führt. Eine Verkürzung der Lagerstandzeiten, Verlust von Wellengesamtsteifigkeiten und Reduzierung von Laufgenauigkeiten an dem Lagersystem ist die Folgen. Axial forces are generated in the case of angular contact bearings under operating load Thread elements to "set" the thread and thus to a inevitable change of the beginning set axial play or Preload values on the storage system. Shortening the downtimes, Loss of total shaft stiffness and reduction of running accuracy the storage system is the consequence.

Verfahren zur definierten Änderung einer Lagervorspannung bei Wellenlagerung in mindestens 2 SchräglagernProcess for the defined change of a bearing preload for shaft bearings in at least 2 angular bearings

Das Verfahren beruht darauf, dass das Passungsübermaß des zu verschiebenden Ringes durch Einpressen eines Fluids in die Passfüge kurzzeitig eine erhebliche Reibungsminderung erfährt, was eine leichte Verschiebbarkeit des Ringes zur Folge hat. Mit einer definierten axialen Kraft auf den einzustellenden Lagerung lässt sich eine gewünschte Vorspannung im Lagersystem ermöglichen. Nach Ablassen des Fluiddruckes kommt entweder die Haltekraft aus dem Übermaß der Passung zur Wirkung, oder bei Anwendung eines Klebers als Fluid, verklebt das in der Passfuge verbleibende Fluid den Ring mit der Welle bzw. dem Gehäuse. Der Ring kann nach dem Aushärten des Fluids mit den üblichen Gewindeelementen axial gesichert werden. Die Befestigung der Gewindeelemente kann mit dem vorgegebenen Anzugsmoment erfolgen. Ein Setzen des Gewindes ist nicht zu befürchten. Die eingestellte Lagervorspannung bleibt bestehen. The method is based on the fit excess of the one to be moved Ring by pressing a fluid into the fitting joint for a short time The friction is reduced, which results in the ring being easy to move Has. With a defined axial force on the bearing to be adjusted enable a desired preload in the storage system. After draining the Fluid pressure comes either from the excess force of the fit Effect, or when using an adhesive as a fluid, glues in the fit joint remaining fluid the ring with the shaft or the housing. The ring can follow the hardening of the fluid axially secured with the usual threaded elements become. The fastening of the threaded elements can be done with the given Tightening torque. There is no fear of threading. The set bearing preload remains.

Um handelsübliche Druckerzeuger mit hydraulischen Ölen verwenden zu können erfolgt eine Trennung zwischen Hydrauliköl und Klebefluid mittels eines Kolbens in einer durchmesser- und volumenmäßig abgestimmten Bohrung vor der Passfüge. To be able to use commercially available pressure generators with hydraulic oils there is a separation between hydraulic oil and adhesive fluid by means of a piston in a diameter and volume-coordinated bore in front of the fitting joint.

Vorgehensweisemethod

Am Beispiel einer Getriebeabtriebswellenlagerung in 2 Kegelrollenlagern in O- Anordnung und Umfangslast für die Innenringe soll die Vorgehensweise beschrieben werden. Using the example of a gearbox output shaft bearing in 2 tapered roller bearings in O- The procedure and arrangement and circumferential load for the inner rings should be described become.

Die Welle ist für den Innenringsitz des Lagers (2) gemäß der Ausführungen für Hydraulikmontage mit Versorgungsbohrungen (5) und einer Ringnut (3) vorzubereiten. Die radiale Bohrung (4) zwischen Ringnut und axialer Versorgungsbohrung (5) wird hinsichtlich ihres Bohrungsdurchmessers so gewählt, dass mindestens das 1,5-fache des Ringnutvolumens aufgenommen werden kann. The shaft must be prepared for the inner ring seat of the bearing ( 2 ) according to the hydraulic assembly with supply holes ( 5 ) and an annular groove ( 3 ). The radial diameter of the radial bore ( 4 ) between the annular groove and the axial supply bore ( 5 ) is selected so that at least 1.5 times the volume of the annular groove can be accommodated.

Dabei ist das Trennkolbenvolumen zu berücksichtigen. Der Trennkolben (6) wird von der Ringnutseite aus bis zur Querbohrung eingebracht, anschließend wird die radiale Bohrung mit einem Klebefluid aufgefüllt. Die Lagersitzstellen sind vorher von überschüssigem Konservierungsmittel, Ölen und Fetten zu befreien. Lager (1) + (2) werden gemäß Skizze montiert. Die Innenringe sind vorzugsweise warm zu montierten um eine Oberflächenbeschädigung der Welle zu vermeiden. The separating piston volume must be taken into account. The separating piston ( 6 ) is inserted from the ring groove side to the cross hole, then the radial hole is filled with an adhesive fluid. Excess preservative, oils and greases must be removed from the bearing seats beforehand. Bearings ( 1 ) + ( 2 ) are assembled according to the sketch. The inner rings should preferably be installed warm to avoid damaging the surface of the shaft.

Auf das Wellengewinde wird eine Mutter mit einer definierten, axialen Federkraft aufgeschraubt. Die eingestellte Federkraft ist geringer zu wählen als die Haltekraft aus dem Passungsübermaß des Lagerinnenringes (2). Die Haltekraft des Innenringes resultiert aus der Ringwandstärke, dem vorliegenden Übermaß und dem Reibwert von Stahl auf Stahl. A nut with a defined, axial spring force is screwed onto the shaft thread. The set spring force is to be selected less than the holding force from the excess fit of the bearing inner ring ( 2 ). The holding force of the inner ring results from the ring wall thickness, the existing oversize and the coefficient of friction from steel to steel.

Über die Versorgungsbohrung (5) wird nun Hydrauliköl, je nach Passungsübermaß und Innenringwandstärke, mit einem hohen Druck aufgebracht. Über den Trennkolben wird das Klebefluid in die Passfuge gepresst. Das Klebefluid senkt kurzzeitig den Reibwert zwischen Welle und Lagerinnenring ähnlich einem Hydrauliköl. Eine definierte axiale Federkraft verschiebt den Innenring auf die gewünschte Vorspannung. Nach ablassen des Druckes wird der größte Teil des Klebefluids aus der Passfuge zurückgedrängt. Nach kurzer Zeit stellt sich wieder ein hoher Reibwert ein. Zusätzlich härtet der verbleibende Kleber in der Passfuge aus und stellt eine feste Verbindung zwischen Welle und Innenring her. Die Mutter und das Federpaket sind gegen eine Nutmutter auszutauschen. Durch die Schrumpfklebeverbindung entsteht eine Haltekraft des Innenringes, die eine Nutmutter mit dem erforderlichen Drehmomentanzug zulässt. Hydraulic oil is now applied at high pressure via the supply bore ( 5 ), depending on the fit oversize and the inner ring wall thickness. The adhesive fluid is pressed into the fitting joint via the separating piston. The adhesive fluid briefly lowers the coefficient of friction between the shaft and the bearing inner ring, similar to a hydraulic oil. A defined axial spring force moves the inner ring to the desired preload. After releasing the pressure, most of the adhesive fluid is pushed back out of the fitting joint. After a short time, a high coefficient of friction reappears. In addition, the remaining adhesive hardens in the fitting joint and creates a firm connection between the shaft and the inner ring. The nut and the spring assembly are to be exchanged for a locknut. The shrink adhesive connection creates a holding force for the inner ring that allows a locknut with the required torque.

Eine axiale Spielveränderung durch den Setzeffekt des Gewindes ist somit im späteren Betrieb ausgeschlossen. An axial change in play due to the setting effect of the thread is therefore later Operation excluded.
