Description

Die vorliegende Erfindung betrifft ein synthetisches oder mineralisches Hochleistungs-Industrie-Getriebeöl mit verbesserten Gebrauchswert-Eigenschaften, mit den im Oberbegriff des Schutzanspruchs 1 angegebenen Merkmalen.The The present invention relates to a synthetic or mineral High-performance industrial gear oil with improved use-value properties, with those in the preamble of the protection claim 1 specified characteristics.

Aus dem Stand der Technik sind Industrie-Getriebeöle und Hochleistungs-Industrie-Getriebeöle bekannt, welche aufgrund ihrer spezifischen thermischen Stabilität je nach Anwendungsfall über eine beschränkte Einsatzdauer beziehungsweise Stabilitätsdauer von nur einem bis zwei Jahren verfügen, nämlich über eine Einsatzdauer beziehungsweise Standzeit von nur 5.000 bis 6.000 Betriebsstunden im Einschichtbetrieb beziehungsweise 10.000 Betriebsstunden im Dreischichtbetrieb.Out The prior art discloses industrial gear oils and high performance industrial gear oils. which depending on their specific thermal stability depending on Use case over one limited Duration of use or stability duration of only one to two Years, namely about one Duration of use or service life of only 5,000 to 6,000 operating hours in the Single-shift operation or 10,000 operating hours in three-shift operation.

Diese bekannten Industrie-Getriebeöle und Hochleistungs-Industrie-Getriebeöle sind insbesondere deswegen nachteilig, weil es spätestens nach Ablauf dieser ohnehin kurzen Einsatzdauer von nur einem bis zwei Jahren -insbesondere durch oxidativen und/oder thermischen Additiv-Abbau- zur gefürchteten Schlammbildung und damit zu schädlichen Ablagerungen im Getriebe kommt, insbesondere an unbelasteten Maschinenbauteilen und in Wälzlagern, wodurch der Gebrauchswert dieser bekannten Getriebeöle erheblich eingeschränkt wird.These known industrial gear oils and high performance industrial gear oils are particularly so disadvantageous because it is at the latest after expiry of this already short duration of use of only one to two years - especially by oxidative and / or thermal Additive Removal To The Dreaded Mud formation and thus harmful Deposits in the gearbox come, in particular on unloaded machine components and in rolling bearings, whereby the utility value of these known transmission oils considerably limited becomes.

Aufgabe der vorliegenden Erfindung ist daher die Bereitstellung eines synthetischen oder mineralischen Industrie-Getriebeöles mit deutlich verbesserten Gebrauchswert-Eigenschaften, insbesondere mit einer erheblich ausgeprägteren Standzeit und Stabilitätsdauer im Einsatz als Getriebeöl, und zwar ohne Schlammbildung und Bildung von Ablagerungen sowie ohne das Erfordernis eines zwischenzeitlichen Ölwechsels.task The present invention therefore provides a synthetic or mineral industrial gear oils with significantly improved Use-value properties, in particular with a considerably longer service life and stability period in use as transmission oil, without sludge formation and formation of deposits as well without the requirement of an interim oil change.

Erfindungsgemäß wird diese Aufgabe bei einem gattungsgemäßen Industrie-Getriebeöl durch die im kennzeichnenden Teil des Schutzanspruchs 1 angegebenen Merkmale gelöst.According to the invention this Task in a generic industrial gear oil through the specified in the characterizing part of claim 1 protection features solved.

Besonders bevorzugte Ausführungsformen sind Gegenstand der Unteransprüche.Especially preferred embodiments are Subject of the dependent claims.

Das erfindungsgemäße synthetische oder mineralische Hochleistungs-Industrie-Getriebeöl umfaßt als erste Hauptkomponente A) einen Polyalphaolefin/Polyol-Ester-Grundstoff oder ein Solvent-Neutral-Raffinat und als zweite Hauptkomponente B) ein Additivpaket.The synthetic according to the invention or high performance mineral industrial gear oil is the first to be included Main component A) a polyalphaolefin / polyol ester base or a solvent-neutral raffinate and as a second major component B) an additive package.

In der Regel umfaßt dieses Additivpaket B) mehrere Komponenten, insbesondere a) einen oder mehrere Korrosionsinhibitoren und b) ein oder mehrere Antioxidantien und c) einen oder mehrere Reibungsminderer und d) ein oder mehrere Dispergiermittel und e) einen oder mehrere Hochdruck-Zusätze und f) einen oder mehrere Schauminhibitoren und g) einen oder mehrere Pourpoint-Erniedriger.In usually includes this additive package B) several components, in particular a) one or more corrosion inhibitors and b) one or more antioxidants and c) one or more friction reducers and d) one or more Dispersants and e) one or more high-pressure additives and f) one or more foam inhibitors and g) one or more Pour point depressants.

Werden diese beiden Hauptkomponenten A) und B) miteinander vermischt, erhält man ein synthetisches oder mineralisches Hochleistungs-Industrie-Getriebeöl, welches ohne Austausch über eine Stabilitätsdauer in einem Hochleistungs-Industrie-Getriebe verfügt, die im Bereich von 3,50 Jahren bis 4,50 Jahren liegt und damit im Bereich von 8.750,00 Betriebsstunden bis 11.250,00 Betriebsstunden im Einschichtbetrieb oder im Bereich von 26.250,00 Betriebsstunden bis 33.750,00 Betriebsstunden im Dreischichtbetrieb, wobei innerhalb dieser Stabilitätsdauern in Bezug auf das Hochleistungs-Industrie-Getriebeöl Rückstandsfreiheit und Schlammfreiheit gegeben sind.Become these two main components A) and B) mixed together, you get a Synthetic or mineral high performance industrial gear oil, which without exchange over a stability period in a high performance industrial gearbox that has a range of 3.50 Years to 4.50 years and thus in the range of 8,750.00 operating hours up to 11,250.00 operating hours in single-shift operation or in the area from 26,250.00 operating hours to 33,750.00 operating hours in three-shift operation, where within these stability periods in terms of high-performance industrial gear oil residue and sludge given are.

In der Regel weist das erfindungsgemäße synthetische oder mineralisches Hochleistungs-Industrie-Getriebeöl eine Reibungszahl auf, welche beispielsweise im Bereich von 0,02 bis 0,06 -gemessen nach der DIN 51834- liegt.In As a rule, the inventive synthetic or mineral High-performance industrial gear oil a coefficient of friction, for example in the range of 0.02 to 0.06-measured according to DIN 51834-.

Im Falle einer besonders bevorzugten Ausführungsform des erfindungsgemäßen synthetischen oder mineralischen Hochleistungs-Industrie-Getriebeöles steigt die Reibungszahl bei einer kontinuierlichen oder stufenweise Erhöhung des Anpreßdruckes von zwei Reibpartnern um jeweils 50 Newton bei einer Flächenpressung im Bereich von 0,1 bis 50 Newton/mm2 vorzugsweise um nicht mehr als jeweils 0,1 μ an.In the case of a particularly preferred embodiment of the synthetic or mineral high-performance industrial gear oil according to the invention, the coefficient of friction increases in a continuous or stepwise increase of the contact pressure of two friction partners by 50 Newton at a surface pressure in the range of 0.1 to 50 Newton / mm 2 preferably by no more than 0.1 μ each.

Ein besonderer Vorteil des erfindungsgemäßen synthetischen oder mineralischen Hochleistungs-Industrie-Getriebeöles besteht darin, daß es die Entstehung von Grauflecken sowie von Pittings an metallischen Reibpartnern wirksam verhindert.One particular advantage of the synthetic or mineral according to the invention High-performance industrial gear oil is that it is the Formation of gray patches and pittings on metallic friction partners effectively prevented.

Ebenfalls von besonderem Vorteil ist bei dem erfindungsgemäßen synthetischen oder mineralischen Hochleistungs-Industrie-Getriebeöl, daß es durch mikroskopisch kleine Ausbrüche auf den Oberflächen von Reibpartnern entstandene Grauflecken (Micropittings) wieder einglättet:
Zu diesem Zwecke kann das erfindungsgemäße synthetische oder mineralische Hochleistungs-Industrie-Getriebeöl beispielsweise polare Additivbestandteile zur absorptiven Anlagerung an die Reibpartner umfassen, wobei es durch Chemisorption zur Ausbildung von ausgeprägten tribologischen Reaktionsschichten kommen kann, und diese eine starke Einglättung der Oberflächenbereiche der Reibpartner unterstützen können, ohne selbst einen ausgeprägten Anteil an Eisen aufzuweisen.Likewise of particular advantage in the case of the synthetic or mineral high-performance industrial gear oil according to the invention is that it is smoothed out again by micro-pits formed by microscopically small outbreaks on the surfaces of friction partners:
For this purpose, the synthetic or mineral high-performance industrial gear oil according to the invention may comprise, for example, polar additive constituents for absorptive attachment to the friction partners, whereby chemisorption can lead to the formation of pronounced tribological reaction layers, and these can promote a strong smoothing of the surface areas of the friction partners, without even having a pronounced amount of iron.

Nach der Chemisorption der tribologischen Reaktionsschichten können die äußersten Rauhigkeitsspitzen der Reibpartner eine abrasive Abtragung erfahren und die ausgeprägten tribologischen Reaktionsschichten können eine starke Einglättung der Reibpartner durch plastische Deformation der Rauhigkeiten bewirken.After the chemisorption of the tribological Reaction layers, the extreme roughness peaks of the friction partners undergo an abrasive removal and the pronounced tribological reaction layers can cause a strong saturation of the friction partners by plastic deformation of the roughness.

Im Allgemeinen kann diese Einglättung beispielsweise durch das Eindringen der tribologischen Reaktionsschichten in die oberflächennahen Bereiche der Reibpartner unterstützt werden.in the In general, this is possible for example, by the penetration of the tribological reaction layers into the near-surface Supported areas of friction partners become.
