PROBLEM TO BE SOLVED: To provide a grease composition improving the temperature-rise-suppressive tendency of the constant-velocity joint containing the composition within the range of service temperature of 150°C to -40°C and reducing low-temperature rotating torque, thus improving the boot resistance of the joint, and to provide such a constant-velocity joint which seals-in the grease composition. SOLUTION: The grease composition comprises (A) a base oil comprising 10-95 wt.% of an ester-based synthetic oil produced from an aliphatic alcohol and an aromatic carboxylic acid and 90-5 wt.% of a synthetic hydrocarbon oil, (B) a thickening agent, (C) molybdenum disulfide, (D) molybdenum sulfurized dialkyl dithiocarbamate and (E) zinc dithiophosphate. The constant-velocity joint which seals-in the above grease composition is also provided. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:

And a method of lubricative film processing on a metallic material, in that the lubricative film formed by applying the aqueous lubricant is in a dried weight of 0.5 SIMILAR 40g/m . A water soluble inorganic salt (A) is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdete and a tungstate. The wax (C) is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of a metal having no chemical conversion layer formed thereon.
Abstract:
A constant-velocity joint having a boot and containing a lubricating grease that will not deteriorate the boot of the CVJ while maintaining required torque transmission performance. The constant-velocity joint is filled with a lubricating grease, and the tubular boot is made from a thermoplastic polyester elastomer. The grease contains a base oil, a thickener in the form of a lithium soap such as lithium 12 hydroxystearate or a lithium complex, and extreme-pressure additives in the form of molybdenum disulfide, molybdenum alkyldithiocarbamate and zinc dithiocarbamate.
