Definitions
- the invention relates to industrial gear oil compositions that have been specially designed to have improved friction and/or antiwear properties. That is the industrial gear oil compositions of the invention provide good performance and/or protection in the areas of friction and/or antiwear due to the use of a synergistic combination of additives.
- the industrial gear oil compositions of the invention utilize a combination of certain phosphorus-containing compounds and derivatives of a hydroxy-carboxylic acid, to provide a synergistic improvement in friction and/or antiwear properties.
- 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 components of the gearboxes, eventually leading to 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.
- Another means of protecting an industrial gearbox and extending the life of the fluid lubricating them is to improve the protection the moving parts have from friction and wear, which can lead to part failure and shorter service life.

- the invention includes methods of improving the friction and/or antiwear properties of an industrial gear oil composition.
- the method includes the step of: (1) adding to an industrial gear oil composition, which includes (a) the oil of lubricating viscosity, the following components: (b) the phosphorus-containing compound; and (c) the derivative of a hydroxy-carboxylic acid; resulting in an industrial gear oil composition with friction and/or antiwear properties.
- the methods provide improved friction properties.

- the invention also includes the use of an additive package to improve the friction and antiwear properties of an industrial gear oil composition
- the industrial gear oil composition includes (a) an oil of lubricating viscosity
- the additive package includes (b) a phosphorus-containing compound and (c) a derivative of a hydroxy-carboxylic acid.
- hydrocarbyl substituent or “hydrocarbyl group” is used in its ordinary sense, which is well-known to those skilled in the art. Specifically, it refers to a group having a carbon atom directly attached to the remainder of the molecule and having predominantly hydrocarbon character. Examples of hydrocarbyl groups include:
- hydrocarbon substituents that is, aliphatic (e.g., alkyl or alkenyl), alicyclic (e.g., cycloalkyl, cycloalkenyl) substituents, and aromatic-, aliphatic-, and alicyclic-substituted aromatic substituents, as well as cyclic substituents wherein the ring is completed through another portion of the molecule (e.g., two substituents together form a ring);
- aliphatic e.g., alkyl or alkenyl
- alicyclic e.g., cycloalkyl, cycloalkenyl
- aromatic-, aliphatic-, and alicyclic-substituted aromatic substituents as well as cyclic substituents wherein the ring is completed through another portion of the molecule (e.g., two substituents together form a ring);
- substituted hydrocarbon substituents that is, substituents containing non- hydrocarbon groups which, in the context of this invention, do not alter the predominantly hydrocarbon nature of the substituent (e.g., halo (especially chloro and fluoro), hydroxy, alkoxy, mercapto, alkylmercapto, nitro, nitroso, and sulfoxy);
- hetero substituents that is, substituents which, while having a predominantly hydrocarbon character, in the context of this invention, contain other than carbon in a ring or chain otherwise composed of carbon atoms and encompass substituents as pyridyl, furyl, thienyl and imidazolyl.
- Heteroatoms include sulfur, oxygen, and nitrogen.
- no more than two, or no more than one, non-hydrocarbon substituent will be present for every ten carbon atoms in the hydrocarbyl group; alternatively, there may be no non-hydrocarbon substituents in the hydrocarbyl group.
- Examples 1 to 13 are comparative examples. Each example is either missing component (b) or component (c), or it does not contain enough component (b) in combination with component (c) to produce the benefits of the invention. Examples 14 to 30 are inventive examples.
- Additive B-l is a dialkyl phosphite with alky I groups containing 18 carbon atoms.
- Additive B-2 is a dialkyl phosphite with alky I groups containing 16 to 18 carbon atoms.
- Additive C-l is an ester derivative of tartaric acid.
- Additive C-2 is an imide derivative of tartaric acid.
- the additive pack used in all of the examples includes an extreme pressure agent, a combination of antiwear agents, a rust inhibitor, a metal deactivator, a antifoam agent, a demulsifier, and a copper deactivator.
- compositions of the invention provide surprisingly improved performance as shown by the HFRR results.
- Comparative example 1 is a baseline example with only a small amount (less than 0.3 percent by weight) of component (b) present and no component (c) present at all. All of the inventive examples have a better wear result and a better COF than Example 1.
- Comparative examples 3 to 13 either contain an insufficient amount of component (b), an insufficient amount of the combination of component (b) and component (c), or no component (c) at all. All of the inventive examples have a better wear result, a better COF, or both, when compared to Examples 3 to 13.
- Comparative examples 2 and 14 to 17 are comparative examples that show what high levels of component (b) are required to achieve results similar to those made possible by the present invention. Even with such high treat rates, comparative example 2 still gives a poor wear result. Comparative examples 14 to 17 give good wear and COF results but only with a very high treat rate of component (b).
- Inventive examples 18 to 30 show that when the combination of components (b) and (c) are used in the proper way (a sufficient amount of component (b) and a sufficient total amount of both components together) a synergistic benefit is seen, and this benefit is demonstrated by the examples above to occur with different examples of component (b) and different examples of component (c), over a wide range of treat rates.
- the transitional term "comprising,” which is synonymous with “including,” “containing,” or “characterized by,” is inclusive or open-ended and does not exclude additional, un-recited elements or method steps.
- the term also encompass, as alternative embodiments, the phrases “consisting essentially of and “consisting of,” where “consisting of excludes any element or step not specified and “consisting essentially of permits the inclusion of additional un-recited elements or steps that do not materially affect the basic and novel characteristics of the composition or method under consideration.
