    Abstract: An oil-mist-free and high-speed electric spindle is provided by the present invention, which is capable of avoiding an environmental pollution caused by oil mist, avoiding harming the physical health of an employee, and saving energy. The oil-mist-free and high-speed electric spindle of the present invention includes a shell, a stator and a rotator. Using a bearing provided on a bearing providing position of the shell, the stator and the rotor are separated by a gap and freely rotatably supported on the shell. A labyrinth sealing structure, which covers the bearing providing position, is provided on an outside of the bearing providing position. The labyrinth sealing structure has a channel which opens to an atmosphere. And a through-hole is provided on the shell, wherein one end of the through-hole opens to the shelter, and the other end of the through-hole is connected with the channel of the labyrinth sealing structure. And the bearing providing position is filled with a lubricating grease which is a total synthesis grease of polyurea that is mainly composed of a base oil and contains a nanometer anti-wear additive. Popularizing the electric spindle of the present invention is expected to save approximately 3 billion kilowatt-hours of electricity and over 60 thousand tons of high quality lubricating grease per year.

    Abstract translation: 本发明提供了一种不含油雾的高速电动主轴，能够避免油雾引起的环境污染，避免损害员工的身体健康，节约能源。 本发明的无油雾高速电动主轴包括外壳，定子和转子。 使用设置在提供壳体的位置的轴承上的轴承，定子和转子由间隙分开并且自由旋转地支撑在壳体上。 覆盖轴承提供位置的迷宫式密封结构设置在轴承提供位置的外侧。 迷宫式密封结构具有通向大气的通道。 并且在壳体上设有通孔，其中通孔的一端通向遮蔽物，并且通孔的另一端与迷宫式密封结构的通道连接。 并且轴承提供位置填充有润滑脂，该润滑脂是主要由基础油组成并含有纳米抗磨添加剂的聚脲的总合成润滑脂。 推广本发明的电主轴预计每年可节约约30亿千瓦小时的电力和6万吨高品质的润滑脂。

    Abstract: A method and compositions for lubricating surfaces with lubricating oils exhibiting increased phosphorous retention. The lubricated surface includes a lubricant composition containing a base oil of lubricating viscosity, an amount of a phosphorus-containing compound and an amount of at least one hydrocarbon soluble titanium compound that is effective to provide an aged catalyst temperature that converts at least fifty percent of exhaust gas hydrocarbons, carbon monoxide, and NOx that is lower than an aged catalyst temperature that converts at least fifty percent of exhaust gas hydrocarbons, carbon monoxide, and NOx of the lubricant composition devoid of the hydrocarbon soluble titanium compound.
