GREASE COMPOSITION FOR CONSTANT VELOCITY JOINTS |
摘要 |
The present invention provides a grease composition for use in constant velocity joints, having improved wear resistance and endurance characteristics. The grease is made by incorporating in a urea grease (A) a molybdenum dialkyldithiocarbamate, (B) a molybdenum dithiophosphate, (C) 2-(4-morpholinyldithio)benzothiazole and (D) a calcium sulphonate. The blended amount of (A)+(B) is made not more than 10% by weight, and that of (C) and (D) not more than 3% by weight respectively. Also, a grease for use in constant velocity joints is made by further adding (E) zinc dithiophosphate to the aforementioned components (A)+(B)+(C)+(D) in a blended amount of not more than 3% by weight. |
