Abstract
The present invention provides a grease composition for constant velocity joints, which includes a lubricating base oil, a thickener including a nitrogen-containing compound, a triglyceride, a diester, and a boron nitride, wherein a total content of the triglyceride and the diester is 1 to 5 mass % based on a total amount of the grease composition, and a mass ratio of a content of the triglyceride to a content of the diester (triglyceride/diester) is 0.3 to 1.5.
Claims5
A grease composition for constant velocity joints comprising:
- a lubricating base oil;
- a thickener comprising a nitrogen-containing compound;
- a triglyceride;
- dioctyl adipate;
- and
- a boron nitride,
- wherein a total content of the triglyceride and the dioctyl adipate is 1 to 5 mass % based on a total amount of the grease composition, and a mass ratio of a content of the triglyceride to a content of the dioctyl adipate (triglyceride/dioctyl adipate) is 0.3 to 1.5 wherein a content of the boron nitride is 0.05 to 1 mass % based on the total amount of the grease composition.
