Definitions

  • the invention relates to the use of a fatty phosphite for reducing the operating temperature of an industrial gearbox.
  • One means of protecting an industrial gearbox and extending the life of the fluid lubricating them is to reduce the temperature at which it operates. It is generally known that extended exposure to the high temperatures that industrial gearboxes commonly operate under increases the wear and tear on the parts of the gearboxes, eventually leading to part failure. This negative impact of high operating temperature is the result of multiple forces, including but not limited to the fact that the high temperatures can accelerate the break-down of the protective additives and increase the oxidation of the base fluid present in the industrial gearbox lubricant, thus leaving the parts of the gearbox less protected over time. Reducing the operating temperature of an industrial gearbox will result in improved performance over time.
  • the invention provides the use of a fatty phosphite for reducing the operating temperature of an industrial gearbox, said use comprising the steps of: (I) adding to an industrial gear oil lubricant comprising (a) an oil of lubricating viscosity, and (b) an industrial gear lubricant additive package, (c) a fatty phosphite such that the lubricant contains at least 1.0 percent by weight fatty phosphite, and (II) operating the industrial gearbox while supplying the industrial gear oil lubricant to the industrial gearbox, wherein (b) the industrial gear lubricant additive package comprises one or more antiwear additives and/or extreme pressure agents, one or more rust and/ or corrosion inhibitors, one or more foam inhibitors, one or more demulsifiers, or any combination thereof.
  • the industrial gear compositions include: (a) an oil of lubricating viscosity; (b) an industrial gear lubricant additive package; and (c) a fatty phosphite present at no less than 1.0 percent by weight of the overall composition.
  • the industrial gear lubricant additive package may include a demulsifier, a dispersant, and a metal deactivator.
  • the 1.0 percent by weight minimum of the fatty phosphite is included as it is believed that, in at least some embodiments, at least this amount of fatty phosphite is necessary to see the described benefits in the industrial gear oil compositions, namely the reduced gearbox operating temperature.
