Abstract

Compositions d'huile lubrifiante et de fluide fonctionnel présentant une meilleure stabilité aux températures élevées et contenant au moins une composition contenant du phosphore et au moins une composition soluble dans l'huile et contenant de l'azote. Plus particulièrement, les compositions lubrifiantes et de fluide fonctionnel ci-décrites comprennent (A) une quantité importante d'une huile de viscosité indiquée pour la lubrification, et une plus faible quantité de (B-1) au moins un sel d'amine soluble d'au moins une composition d'acide phosphorique substitué caractérisée par la formule (I), où R1 représente hydrogène ou un groupe hydrocarbyle, R2 est un groupe hydrocarbyle, et les deux groupes X représentent soit O soit S, et (C) au moins une composition soluble contenant de l'azote préparée par la réaction d'un composé produisant de l'acide succinique substitué par un hydrocarbure avec au moins environ un demi-équivalent, par équivalent du composé produisant l'acide, d'une amine contenant au moins un hydrogène fixé sur un atome d'azote. De préférence, les sels d'amine des acides phosphoriques utilisés dans les compositions lubrifiantes ci-décrites sont dérivés d'amines primaires, et les compositions solubles contenant de l'azote (C) contiennent également du bore. Les compositions lubrifiantes ci-décrites sont particulièrement utiles dans des applications se rapportant à des engrenages exigeant une stabilité thermique élevée à des températures situées autour de 160°C, avec un fonctionnement intermittent à des températures allant jusqu'à environ 200°C.
