Abstract
The grease composition for constant velocity joints of the invention is characterized by comprising a lubricating base oil, a thickener, carbon black with a mean particle size of not greater than 500 nm, and an organic molybdenum compound. A grease composition for constant velocity joints according to the invention can achieve a highly satisfactory balance between anti-flaking, anti-seizure and anti-wear without using lead compounds, and can sufficiently maintain these properties with long-term use.
Claims
exact text as granted — not AI-modified1 . A grease composition for constant velocity joints, comprising a lubricating base oil, a thickener, carbon black with a mean particle size of not greater than 500 nm, and an organic molybdenum compound.
2 . The grease composition for constant velocity joints according to claim 1 , further comprising at least one from among sulfur-based extreme pressure agents, phosphorus-based extreme pressure agents and zinc-based extreme pressure agents.
3 . The grease composition for constant velocity joints according to claim 1 , further comprising at least one selected from among complexes of fatty acid salts and carbonates, wherein said fatty acids are overbased by the carbonates, and organic acid salts.Cited by (0)
