Vorrichtungen, die zur Kraftübertragung dienen, wie z. B. Zahnräder, Kegelräder, Schnecken oder Schneckenräder mit den verschiedensten Verzahnungsformen, müssen bekanntlich für eine optimale Kraftausnutzung bei Benutzung von Schmiermitteln auf der Grundlage von Mineralölen — auch von solchen mit Zusatzmitteln — bestimmte Mindestforderungen, insbesondere hinsichtlich Abmessungen, bei einem gegebenen Werkstoff und/oder gegebener Oberflächengüte erfüllen.Devices that are used for power transmission, such. B. gears, bevel gears, worms or As is well known, worm gears with a wide variety of toothing shapes must be used for optimum use of force when using lubricants based on mineral oils - including those with Admixtures - certain minimum requirements, especially in terms of dimensions, for a given Meet the material and / or the given surface quality.
Es wurde nun beobachtet, daß diese Mindestforderungen überraschenderweise beträchtlich unterschritten werden können, wenn man als Schmiermittel, d. h. als Schmierfette oder Schmieröle, —(CH2)4 — O-Gruppen enthaltende Polyäther bzw. Polyätherester oder ihre Mischungen verwendet. Demzufolge besteht die Erfindung in der Verwendung von —(CH2)4 — O-Gruppen enthaltenden Polyäthern bzw. Polyätherestern als Schmiermittel in Kraftübertragungsvorrichtungen (Getrieben), deren Abmessungen die bei Benutzung von Schmiermitteln auf der Grundlage von Mineralölen für eine optimale Kraftausnutzung zu erfüllenden Mindestforderungen unterschreiten.It has now been observed that, surprisingly, these minimum requirements can be fallen short of considerably if the lubricants used, ie as lubricating greases or lubricating oils, are - (CH 2 ) 4 - O groups-containing polyethers or polyether esters or their mixtures. Accordingly, the invention consists in the use of - (CH 2 ) 4 - O groups-containing polyethers or polyether esters as lubricants in power transmission devices (gears), the dimensions of which meet the minimum requirements for optimum use of power when using lubricants based on mineral oils fall below.
Die für die Durchführung der Erfindung geeigneten Polyäther und Polyätherester können in mannigfacher Weise erhalten worden sein. Geeignet sind z. B. die Verbindungen, die erhalten sind durch Polymerisation von Tetrahydrofuran oder von Gemischen aus Tetrahydrofuran und 1,2-Oxidoverbindungen, etwa gemäß den Verfahren nach der französischen Patentschrift 898 269, gegebenenfalls durch weitere Umsetzung von austauschfähiges Halogen enthaltenden Polyäthern bzw. Polyätherestern mit den Alkaliverbindungen von Alkoholen, 1,2-, 1,3- oder 1,4-Glykolen, Phenolen oder Carbonsäuren, etwa gemäß dem Verfahren nach der deutschen Patentschrift 883 506. Ferner sind solche Verbindungen geeignet, die durch Kondensation von 1,4-Butylenglykol mit sich selbst oder mit 1,2- bzw. 1,3-Glykolen oder mit 1,2- bzw. 1,3-Oxidoverbindungen erhalten sind; auch solche Verbindungen sind brauchbar, die durch Umsetzung von 1,4-Dichlorbutan, <5,<5'-Dichlordibutyläther oder <5,<5'-Dichlordibutoxybutan mit 1,2-, 1,3- oder 1,4-Glykolen erhältlich sind. Schließlich sind auch solche Verbindungen für die Zwecke der Erfindung geeignet, die aus den obenerwähnten Verbindungen, soweit diese noch freie Hydroxylgruppen tragen, durch Veresterung mit ein- oder mehrwertigen Carbonsäuren erhalten sind, etwa gemäß dem Verfahren nach der deutschen Patentschrift 917 028.The polyethers and polyether esters suitable for carrying out the invention can be used in a variety of ways Way have been received. Suitable are e.g. B. the compounds obtained by polymerization of tetrahydrofuran or of mixtures of tetrahydrofuran and 1,2-oxido compounds, for example according to the method according to French patent specification 898 269, if necessary by further implementation of exchangeable halogen-containing polyethers or polyether esters with the alkali compounds of Alcohols, 1,2-, 1,3- or 1,4-glycols, phenols or Carboxylic acids, for example according to the method according to German patent specification 883 506. Furthermore, such Compounds suitable that are formed by condensation of 1,4-butylene glycol with itself or with 1,2- or 1,3-glycols or with 1,2- or 1,3-oxido compounds are preserved; those compounds can also be used which are obtained by reacting 1,4-dichlorobutane, <5, <5'-dichlorodibutyl ether or <5, <5'-dichlorodibutoxybutane with 1,2-, 1,3- or 1,4-glycols are available. After all, there are also such connections suitable for the purposes of the invention from the above-mentioned compounds, insofar as these are still free Carry hydroxyl groups, obtained by esterification with mono- or polybasic carboxylic acids, for example according to the method according to German patent specification 917 028.

als Schmiermittel im Sinne der Erfindung zu verwenden, kann man sie gegebenenfalls auch gemeinsam mit anderen Schmiermitteln einsetzen; als solche seien beispielsweise genannt Kohlenwasserstofföle bzw. -fette, ferner Esteröle, wie sie z. B. aus Glykolen und ein- oder mehrwertigen Carbonsäuren erhältlich sind, sowie Polyäther bzw. Polyätherester, die statt — (CHa)4 — O-Gruppen beispielsweise — (CHa)2 — O- oder —(CHg)3 — O-Gruppen enthalten; näher beschrieben sind solche Verbindungen unter anderem in der deutschen Patentanmeldung B 6898 IVb/12o, in der deutschen Patentschrift 767 240 bzw. in den britischen Patentschriften 642 037, 662 650, 659103, 716 339 und 666 697.to be used as a lubricant for the purposes of the invention, they can optionally also be used together with other lubricants; as such, for example, hydrocarbon oils or fats, also ester oils, such as are mentioned, for. B. from glycols and mono- or polybasic carboxylic acids, as well as polyethers or polyether esters, which instead of - (CHa) 4 - O groups contain, for example - (CHa) 2 - O or - (CHg) 3 - O groups ; Such compounds are described in more detail, inter alia, in German patent application B 6898 IVb / 12o, in German patent specification 767 240 and in British patents 642 037, 662 650, 659103, 716 339 and 666 697.
Feste oder halbfeste Polyäther bzw. Polyätherester, die — (CHa)4 — O-Gruppen enthalten, können durch Lösungsmittel in eine für Schmierzwecke geeignete Form gebracht werden; als Lösungsmittel kommen hierfür vor allem solche flüssigen Verbindungen in Betracht, die selbst Schmiermitteleigenschaften besitzen, wie z. B. flüssige Polyäther bzw. Polyätherester oder Esteröle. Andererseits kann man die flüssigen Polyäther bzw. Polyätherester, die -(CHg)4-O-Gruppen enthalten, mit festen Polyäthern bzw. Polyätherestern oder mit Fetten versetzen, etwa um ihre Viskosität zu erhöhen; man kann die flüssigen Polyäther bzw. Polyätherester gewünschtenfalls auch mit geeigneten fettsauren Salzen versetzen, wenn man sie beispielsweise zu Schmierfetten verfestigen will.Solid or semi-solid polyethers or polyether esters which contain - (CHa) 4 - O groups can be converted into a form suitable for lubricating purposes by means of solvents; as solvents for this purpose, especially those liquid compounds come into consideration which themselves have lubricating properties, such as. B. liquid polyethers or polyether esters or ester oils. On the other hand, the liquid polyethers or polyether esters containing - (CHg) 4 -O groups can be mixed with solid polyethers or polyether esters or with fats, for example in order to increase their viscosity; the liquid polyethers or polyether esters can, if desired, also be mixed with suitable fatty acid salts if, for example, they are to be solidified to form lubricating greases.
Es hat sich als zweckmäßig erwiesen, die — (CH2)4 — O-Gruppen enthaltenden Polyäther bzw. Polyätherester bei ihrer erfindungsgemäßen Verwendung mit einem Zusatz an Antioxydantien zu versehen, etwa solchen auf der Grundlage von Hydroxy- bzw. Aminoverbindungen, wie z. B.

In den eingangs erwähnten deutschen Patentschriften 883 506 und 917 028 sowie in der französischen Patentschrift 898 269 sind die — (CH2)4 — O-Gruppen enthaltenden Polyäther und Polyätherester bereits als Schmiermittel beschrieben; es wird hier jedoch lediglich von einer vorzüglichen bzw. hohen Druckfestigkeit derartiger Polyäther oder Polyätherester gesprochen. Eine entsprechende Druckfestigkeit weisen aber auch die für Kraftübertragungsvorrichtungen verwendeten Schmiermittel auf Mineralölbasis auf. Es fehlt in den genannten Patentschriften jeder Hinweis, daß die — (CH2)4 — O-Gruppen enthaltenden Polyäther oder Polyätherester den Mineralölschmiermitteln in der Druckfestigkeit überlegen sind; die Lehre der vorliegenden Erfindung läßt sich demnach aus diesen Patentschriften nicht ableiten. Auch UntersuchungenIn the German patents 883 506 and 917 028 mentioned at the beginning and in the French patent 898 269 the - (CH 2 ) 4 - O groups-containing polyethers and polyether esters are already described as lubricants; However, it is only spoken of an excellent or high compressive strength of such polyethers or polyether esters. However, the mineral oil-based lubricants used for power transmission devices also have a corresponding compressive strength. There is no indication in the cited patents that the - (CH 2 ) 4 - O groups-containing polyethers or polyether esters are superior to mineral oil lubricants in terms of compressive strength; the teaching of the present invention can therefore not be derived from these patents. Investigations too

Hieraus wird gefolgert, daß die bei Verwendung von Mineralölen geltenden Abmessungen eines Getriebes bei gleichbleibender Belastbarkeit 35 unterschreitbar sind, wenn als SchmiermittelThe lubricant according to the present invention contains the polyether containing 30 - (CH 2 ) 4 - O groups or twice the amount of the load capacity that results from the use of the mineral oil-based lubricant when the polyether ester lubricants are based on mineral oil. It is concluded from this that the dimensions of a transmission that apply when mineral oils are used can be undercut with a constant load capacity 35 when used as a lubricant
