Zusammenfassung: | An industrial gear oil compositions that substantially reduce the operating temperature of a gearbox in which the gear oil compositions are used and related methods. A fatty phosphite is added to an industrial gear oil lubricant in addition to an industrial gear lubricant additive package such that the lubricant contains at least 1.0 percent by weight fatty phosphite. The industrial gearbox is operated while supplying the industrial gear oil lubricant to the industrial gearbox. The fatty phosphite comprises at least one di-hydrocarbyl substituted phosphite, wherein the hydrocarbyl groups have 16 to 18 carbon atoms. The industrial gear lubricant additive package and the fatty phosphite are present in amounts such that the weight ratio of additive package to the fatty phosphite is from 4:1 to 1:5.
La présente invention concerne des compositions d'huiles industrielles pour engrenages améliorées qui réduisent sensiblement la température de fonctionnement d'un réducteur dans lequel sont utilisées les compositions d'huiles pour engrenages. La température de fonctionnement réduite conférée par les compositions décrites conduit à une performance améliorée de l'équipement. L'invention concerne également des procédés de fabrication des compositions d'huiles industrielles pour engrenages et des procédés les utilisant. |
