Title:
LUBRICANT COMPOSITION FOR TRANSMISSION
Document Type and Number:
Japanese Patent JP2022044925
Kind Code:
A
Abstract:
To provide a lubricant composition for a transmission capable of obtaining excellent performance.SOLUTION: The lubricant composition for a transmission comprises: a base oil; and a poly (meth) acrylate and an olefin copolymer as a viscosity modifier. A ratio of the poly (meth) acrylate to the olefin copolymer in the viscosity modifier is 100:0 to 20:80 in mass%. A kinematic viscosity of the composition at 100°C is 5.5 mm2/s or less, a viscosity index is 160 or more, a rate of decrease in 100°C kinematic viscosity after a KRL shear stability test (60°C, after 20 hr) is 2% or less, and a deposit amount in a panel caulking test is 120 mg or less.SELECTED DRAWING: None
