Abstract

The four-lip snap-in seal has sealing contact metal plates (2a,2b,3a,3b) whose edges are rounded in the gap region to form round portions whose diameters are smaller than the bottom diameters of the seal. The radial distance (15) between the sealing lips (1e,1g) is set less than or equal to the radial gap width (14) between two sealing contact metal plates, so that assembly/disassembly of seal is performed by non-destructive seal deformation in region of sealing bulge (1c).

Description

Zur Abdichtung von Großwälzlagern in Gehäusen werden aktuell vor allem gegossene Axiallabyrinthdichtungen eingesetzt. Ein typisches Design ist der 7 zu entnehmen. Diese Dichtungsausführung besteht aus einem gegossenen und bearbeiteten Gehäuselabyrinthring (Pos. 18a, 18b), einem gegossenen und bearbeiteten Wellenlabyrinthring (Pos. 19a, 19b) und einem vorgeschalteten V-Ring (20a, 20b).For the sealing of slewing bearings in housings currently casted axial labyrinth seals are used. A typical design is the 7 refer to. This seal design consists of a cast and machined housing labyrinth (pos. 18a . 18b ), a cast and machined Wellenlabyrinthring (pos. 19a . 19b ) and an upstream V-ring ( 20a . 20b ).

Die Nachteile dieser Dichtungsausführung sind:

  • 1.) Großes Gewicht. Für ein Pendelrollenlager mit 1120 mm Bohrung ergibt sich ein Dichtungsgewicht von ca. 1,5 to je Seite,
  • 2.) Aufwendige Bearbeitung (viel Zerspanung),
  • 3.) Große Leckage-Rate, speziell nach dem ersten Anfahren,
  • 4.) Nur sehr begrenzte Zugänglichkeit des Lagerinnenraumes für Inspektionen oder Altfettentnahmen,
  • 5.) Aufgrund der großen Massen kann die Montage und Demontage nur mittels Kraneinsatz erfolgen,
  • 6.) Keine optimale Gegenlauffläche für den V-Ring (feingedrehte Sphäroguss-Oberfläche, weich).
The disadvantages of this seal design are:
  • 1.) Great weight. For a spherical roller bearing with 1120 mm bore results in a seal weight of about 1.5 to each side,
  • 2.) Elaborate processing (a lot of cutting),
  • 3.) Large leakage rate, especially after the first start,
  • 4.) Only very limited accessibility of the warehouse interior for inspections or old grease removal,
  • 5.) Due to the large masses, the assembly and disassembly can be done only by crane use,
  • 6.) No optimal mating surface for the V-ring (finely machined nodular cast iron surface, soft).

In neueren Designs kommen zunehmend auch Dichtungen mit Radialwellendichtringen (Simmerringe) zum Einsatz. Eine typische Ausführung ist der 8 zu entnehmen.In newer designs are increasingly seals with radial shaft seals (Simmerrings) are used. A typical design is the 8th refer to.

Diese Dichtungsausführung besteht aus einem Dichtungsträger (Pos. 21, 22, 23, 24) aus geschweißtem Stahlblech, einem Feder-vorgespannten Radialwellendichtring (Pos. 25) und einer Wellenschutzhülse (Pos. 26), welche eine gehärtete und geschliffene Oberfläche aufweist.This seal design consists of a seal carrier (pos. 21 . 22 . 23 . 24 ) made of welded sheet steel, a spring-loaded radial shaft seal (pos. 25 ) and a shaft sleeve (pos. 26 ) having a hardened and ground surface.

Hiermit werden 4 wesentliche Vorteile erzielt:

  • 1.) Gewichtsreduzierung,
  • 2.) Sehr geringe Leckagerate,
  • 3.) Optimale Gegenlauffläche für die Dichtungslippe,
  • 4.) Von-Hand-Montage und -Demontage möglich.
This achieves 4 major benefits:
  • 1.) weight reduction,
  • 2.) Very low leakage rate,
  • 3.) Optimum mating surface for the sealing lip,
  • 4.) By hand assembly and disassembly possible.

Trotzdem weist auch dieses Design nach wie vor gravierende Nachteile auf:

  • 1.) Komplizierter, mehrteiliger Aufbau des Dichtungsträgers mit diversen Schweißnähten und Verschraubungs-Stellen...daher teuer in der Herstellung,
  • 2.) Teure Wellenschutzhülse oder Oberflächenhärtung/Schleifen der Gegenlauffläche notwendig,
  • 3.) Zugänglichkeit für Inspektionen/Altfettentnahmen nur durch segmentierten Aufbau des Trägerbleches (Pos. 21) möglich...dies wird die Kosten weiter erhöhen,
  • 4.) Der Radialwellendichtring begrenzt die zulässige Schiefstellung auf max. 0,5° (+/–0,25°).
Nevertheless, this design still has serious disadvantages:
  • 1.) Complex, multi-part construction of the seal carrier with various welds and bolting points ... therefore expensive to manufacture,
  • 2.) Expensive shaft sleeve or surface hardening / grinding of the mating surface necessary,
  • 3.) Accessibility for inspections / old grease removal only by segmented structure of the carrier plate (pos. 21 ) possible ... this will further increase costs,
  • 4.) The radial shaft seal limits the permissible misalignment to max. 0.5 ° (+/- 0.25 °).

Höhere Werte, die durchaus im Betrieb vorkommen können, führen zum Abheben der Dichtlippe und sogar zu Vorschädigungen der Dichtlippe.Higher values, which may well occur during operation, lead to lifting of the sealing lip and even to pre-damaging the sealing lip.

Eine weitere Abdichtungsmöglichkeit wird in dem Patent 10 2010 050 721 ausgeführt. Hier wird die Dichtung direkt am Lager realisiert mittels angeklebtem Dichtungsträgerblech und angeklebtem Gegenlaufblech.Another sealing possibility is disclosed in the patent 10 2010 050 721 executed. Here, the seal is realized directly on the bearing by means of glued gasket carrier plate and glued mating plate.

In der Zusatzanmeldung DE 10 2011 103 441 A1 ist zu obigem Patent eine nachstellbare Dichtlippen-Position ergänzt worden, um den Verschleiß über die Zeit zu kompensieren.In the additional application DE 10 2011 103 441 A1 For example, a replaceable sealing lip position has been added to the above patent to compensate for wear over time.

Aber auch diese Ausführungen weisen nach wie vor wesentliche Nachteile auf:
Patent 10 2010 050 721 :

  • 1.) Mehrteiliger Aufbau des Dichtungsträgerbleches und des Gegenlaufbleches,
  • 2.) Nur sehr begrenzte Zugänglichkeit zum Lagerinnenraum für Inspektionen/Altfettentnahmen
  • Patent-Offenlegung 10 2011 103 441 : Neben den Nachteilen des Patentes 10 2010 050 721 kommt hier der relativ komplizierte Aufbau der Nachstell-Vorrichtung hinzu, was die Kosten deutlich erhöhen wird.
But even these embodiments still have significant disadvantages:
patent 10 2010 050 721 :
  • 1.) Multi-part construction of the seal carrier plate and the mating plate,
  • 2.) Very limited accessibility to the warehouse interior for inspections / old grease removal
  • Patent Publication 10 2011 103 441 : Besides the disadvantages of the patent 10 2010 050 721 Here is the relatively complicated structure of the adjusting device added, which will increase the cost significantly.

4-Lippen-Einschnapp-Dichtungen sind aus WO 2010/043248 A1 , WO 2012/017094 A2 und WO 2012/126529 A1 bekannt.4-lip snap-on seals are off WO 2010/043248 A1 . WO 2012/017094 A2 and WO 2012/126529 A1 known.

Die Erfindung löst obige Probleme durch eine einfach zu montierende/demontierende 4-Lippen-Einschnapp-Dichtung (Pos. 1), deren Dichtlippen (Pos. 1d, 1e, 1f, 1g) mit axialer Vorspannung gegen Dichtungsanlaufbleche (Pos. 2a + 2b, Pos. 3a + 3b) anlaufen.The invention solves the above problems by an easy to install / dismantle 4-lip snap-in seal (pos. 1 ), whose sealing lips (pos. 1d . 1e . 1f . 1g ) with axial preload against sealing contact plates (pos. 2a + 2 B , Pos. 3a + 3b ).

Die Montage/Demontage der Dichtung (Pos. 1) erfolgt dabei durch elastische Verformung der radialen Erstreckung (Pos. 15), sodass diese nach der Verformung kleiner/gleich der Spaltbreite (Pos. 14) zwischen den Dichtungsanlaufblechen (Pos. 2a + 2b, Pos. 3a + 3b) ist.The assembly / disassembly of the seal (pos. 1 ) takes place by elastic deformation of the radial extent (Pos. 15 ), so that after deformation less than / equal to the gap width (pos. 14 ) between the sealing contact plates (pos. 2a + 2 B , Pos. 3a + 3b ).

Hierzu wird die Dichtung (Pos. 1) mit einer sogenannten Dichtungsbeule (Pos. 1c) ausgeführt, welche eine zerstörungsfreie Dichtungsverformung in radialer Richtung zulässt. Dadurch wird es möglich, die Dichtungsanlaufbleche (Pos. 2a + 2b, Pos. 3a + 3b) als einfache, flache Ronden auszuführen, ohne jegliche Abkantungen oder Anschweißungen.For this purpose, the seal (pos. 1 ) with a so-called seal dent (pos. 1c ), which permits nondestructive seal deformation in the radial direction. This makes it possible, the seal contact plates (pos. 2a + 2 B , Pos. 3a + 3b ) as simple, flat blanks, without any bends or welds.

Um die Einschnapp-Montage zu vereinfachen, werden die Dichtungsanlaufbleche (Pos. 2a + 2b, Pos. 3a + 3b) im Spaltbereich abgerundet (Pos. 2c, 3c).To simplify the snap-in mounting, the sealing contact plates (Pos. 2a + 2 B , Pos. 3a + 3b ) in the gap area rounded off (pos. 2c . 3c ).

Die Rundungsradien (Pos. 2c, 3c) werden dabei so gewählt, dass sie etwas kleiner als die Bodenradien (Pos. 1h, 1i) der Dichtung sind, um bei eventuellem Kontakt in Extremlastfällen Vorschädigungen zu vermeiden.The rounding radii (Pos. 2c . 3c ) are chosen so that they are slightly smaller than the ground radii (pos. 1h . 1i ) of the seal are to prevent possible damage in case of contact in extreme load cases.

Des Weiteren werden die Abstände (Pos. 1j, 1k) zwischen den Dichtungsanlaufblechen (Pos. 2a + 2b, Pos. 3a + 3b) und den Dichtungsböden (Pos. 1h, 1i) so gewählt, dass ein Kontakt bezogen auf das max. Betriebsradialspiel des Lagers und der max. zulässigen Schiefstellung von 1° (+/–0,5°) nicht erfolgt.Furthermore, the distances (pos. 1j . 1k ) between the sealing contact plates (pos. 2a + 2 B , Pos. 3a + 3b ) and the sealing floors (pos. 1h . 1i ) chosen so that a contact based on the max. Operational radial clearance of the bearing and the max. permissible misalignment of 1 ° (+/- 0.5 °) has not occurred.

Zur Reduzierung des Dichtungsreibmomentes ist es sinnvoll, die Freiräume (Pos. 16, 17) vor der Montage mit Fett zu befüllen.To reduce the Dichtungsreibmomentes it makes sense, the free spaces (pos. 16 . 17 ) before filling with grease.

Die Dichtungsanlaufbleche (Pos. 2a + 2b, Pos. 3a + 3b) sollten aus Korrosionsschutzgründen entweder aus präzisionsgewalztem Niroblech oder präzisionsgewalztem Stahlblech + Korrosionsbeschichtung gefertigt werden.The seal start plates (pos. 2a + 2 B , Pos. 3a + 3b ) should, for reasons of corrosion protection, be made of either precision rolled niroboard or precision rolled sheet steel + corrosion coating.

Die kostenoptimale Ausführung ergäbe sich aus der Kombination dieser 4-Lippen-Einschnapp-Dichtung mit dem Patent DE 10 2010 050 721 siehe 4.The cost-optimal design would result from the combination of this 4-lip snap-in seal with the patent DE 10 2010 050 721 please refer 4 ,

Weitere Ausführungsbeispiele sind in 5 und 6 dargestellt.Further embodiments are in 5 and 6 shown.

Die Erfindung garantiert den geringstmöglichen Materialeinsatz (Masse), die wenigsten Bauteile, die größtmögliche zulässige Schiefstellung, die einfachste Zugänglichkeit zum Lagerinnenraum und somit auch die kostengünstigste Lösung.The invention guarantees the least possible use of material (mass), the least components, the greatest possible misalignment, the easiest accessibility to the bearing interior and thus the most cost-effective solution.
