GEAR OIL COMPOSITIONS, METHODS OF MAKING AND USING THEREOF |
摘要 |
A gear oil composition is provided. The composition comprises a synergistic blend of mineral oil base stock and polyalphaolefin (PAO) base stock for the oil composition to have a traction coefficient at a slide to roll ratio of 40 percent at 15 mm2/s. of 0.030 or less and a pressure viscosity coefficient of at least 16.0 at 80 °C, 20 Newton load, and 1.1 m/s rolling speed. In one embodiment, the synergistic amount of PAO base stock ranges from 5 to 48 wt. % based on the total weight of the gear oil composition. |
