Definitions
- the present invention relates to urea grease compositions and to gears containing such compositions.
- Petroleum cost has increased sharply since so-called Oil Shock, and resourcing saving and energy saving ideas have been constantly intended in every industrial field, reflecting its influence.
- CVJ constant velocity joints
- CVJ is also employed in 4 wheel drive vehicles and vehicles of four wheel independent suspension type, and the demand is growing.
- CVJ which is also called constant velocity universal joint, is a joint which transmits rotation keeping constant angular speed and torque, and has different types depending on various uses.
- the lubricating agents used for the CVJ are exposed to severer condition as a motor vehicle achieves higher power and higher speed and CVJ itself becomes compact, and therefore, a grease is demanded which reduces friction and wear on sliding portions.
- a seal boot member is required to be mounted on CVJ to prevent leaking of a grease and to prevent invasion of foreign materials and water from outside.
- chloroprene rubber is generally used and polyester resins are also commonly used.
- a grease which is excellent in low friction and wear resistance suppresses vibration and noise of a vehicle body at a time of starting and accelerating and during driving. Moreover, due to its temperature suppressing effect, durability of a seal boot member can be improved. However, excessive increase of temperature promotes ageing of the seal boot member and degradation of a lubricating agent and extremely shortens the life of CVJ.
- lithium-based greases have been conveniently used using sulfur-based compounds such as sulfu ⁇ zed fat and oil, sulfurized olefin and the like, lead naphthenate, metal dithiophosphate, metal dithiocarbamate-based additive and the like.
- sulfur-based compounds such as sulfu ⁇ zed fat and oil, sulfurized olefin and the like, lead naphthenate, metal dithiophosphate, metal dithiocarbamate-based additive and the like.
- a lithium complex grease and a urea grease which are superior in heat resistance to lithium-based greases have been increasingly used.
- U.S. Patent No. 4,514,312 discloses a grease using aromatic amine phosphate as an organic additive containing no sulfur in a urea grease.
- U.S. Patent No. 4,840,740 discloses a grease comprising a urea gresae, an organic molybdenum compound, and zinc dithiophosphate .
- JP-B Japanese Patent Publication
- 04-34590(1992) discloses a urea grease comprising as an essential component a sulfur-phosphorus-based extreme pressure additive comprising 1) molybdenum dialkyldithiocarbamate sulfide and 2) one or a combination of two or more selected from the group consisting of sulfurized fat and oil, sulfurized olefin, tricresyl phosphate, trialkyl thiophosphate and zinc dialkyl dithiophosphate.
- JP-A Japanese Patent Application Laid-Open
- JP-A No. 08-157859 (1996) discloses the use of as additives a molybdenum dialkyldithiocarbamate sulfide and triphenylphosphoro- thionate
- JP- A Japanese Patent Application Laid-Open

- Japanese Patent Application Laid-Open (JP-A) No. 03-231993 (1991) discloses a grease composition using a phosphate oil in a urea compound.
- the present invention relates to a urea grease which is excellent in frictional properties and wear resistance and also has good fitting property to sealants such as chloroprene rubber and polyester resin. More particularly, the present invention relates to a urea grease composition suitable for application to such parts to be grease-lubricated as constant velocity joints, ball joints, and ball bearings in motor vehicles and bearings and gears of various industrial equipments such as the steel and industrial machines and machine tools .
- the present invention relates to a urea grease composition
- a urea grease composition comprising a urea grease and as additives (A) a molybdenum dialkyldithiocarbamate sulfide represented by the formula:
- R 1 and R 2 each independently represents a group selected from the group consisting of alkyl groups having from 1 to 24 carbon atoms; m is 0 or an integer of from 1 to 3; and n is an integer of from 1 to 4 ; provided that the sum of m and n is 4, and (B) a triphenyl phosphate represented by the formula:
- the compounds corresponding to the above-mentioned component (A) have a high melting point.
- examples of those compounds include diethyl sulfide-molybdenum dithiocarbamate, dibutyl-molybdenum dithiocarbamate, diisobutyl sulfide-molybdenum dithiocarbamate, di(2- ethylhexyl) sulfide-molybdenum dithiocarbamate, diamyl sulfide-molybdenum dithiocarbamate, diisoamyl sulfide- molybdenum dithiocarbamate, dilauryl sulfide-molybdenum dithiocarbamate, distearyl sulfide-molybdenum dithiocarbamate.
- the amount added is from 0.5 to 10% by weight, preferably from 0.5 to 5% by weight based on the total weight.
- the amount added is less than 0.5% by weight, effect of improvement in friction resistance and wear resistance is generally insufficient, and when over 10% by weight, no further improvement will generally occur.
- triphenyl phosphate has a melting point of 50 °C and is solid at ambient temperature, it is preferred that the powder is blended with the base grease at a temperature of not less than 50 °C.
- the amount of component (B) preferably is from 0.1 to 10% by weight, more preferably from 0.1 to 5% by weight based on the total weight. When the amount used is less than 0.1% by weight, improvement in friction resistance and wear resistance properties generally cannot be achieved, and when over 10% by weight, further lubricating ability generally cannot be obtained.
- the urea compound any of known thickening agents of urea type can be used. For example, diurea, triurea and tetraurea may be used.
- a mineral oil and/or a synthetic oil can be used as the base oil. If the urea compound is used as a thickening agent it is preferably applied in an amount from 2 to 35% by weight based on the total weight of the base oil and the urea compound.
- additives such as an antioxidant, anticorrosion agent, extreme pressure agent, polymer and the like can further be added to the composition of the present invention.
- the urea grease composition according to the invention are especially suitable for use in gears, more specifically constant velocity joints. Therefore, the present invention further relates to gears, more specifically constant velocity joints, containing such grease .
