Description
技术领域technical field
本发明一种全浮动高速轴承润滑剂组合物属于轴承润滑剂领域。The invention relates to a fully floating high-speed bearing lubricant composition, which belongs to the field of bearing lubricants.
背景技术Background technique
全浮式轴承主要用在高转速、只传递转矩，不承受任何反力和弯矩的场合没有转子,利用0.25-0.4Mpa压力的润滑油充满这两个间隙，使浮动轴承在油膜中随转子轴同向旋转，其转速比转子轴快得多。Full-floating bearings are mainly used in high-speed, torque-transmitting occasions without any reaction force and bending moment. The two gaps are filled with lubricating oil with a pressure of 0.25-0.4Mpa, so that the floating bearings can move freely in the oil film. The rotor shafts rotate in the same direction at a much faster speed than the rotor shaft.
涡轮增压器被广泛应用于多种发动机中，由于外在高压，高压和高速运转的工作状态下，其工作状况非常恶劣，工作要求较为苛刻，因为对制造材料(通常采用耐高温有色金属材料)和加工技术较高，其中制造难度较高的是支撑涡轮轴运转的“浮式轴承”，它的工作转速高达10万转/分以上，一般材料制造的轴承是无法承受的。由于轴承与机体壁间采用油液的冷却、润滑、清洗、防腐、防锈、减摩，又称其为“全浮式轴承”。Turbochargers are widely used in a variety of engines. Due to the external high pressure, high pressure and high-speed operating conditions, their working conditions are very harsh, and the work requirements are relatively demanding, because the manufacturing materials (usually high-temperature resistant non-ferrous metal materials are used) ) and high processing technology, among which the most difficult to manufacture is the "floating bearing" that supports the operation of the turbine shaft. Its working speed is as high as 100,000 rpm or more, and bearings made of general materials cannot bear it. Due to the use of oil between the bearing and the body wall for cooling, lubrication, cleaning, anti-corrosion, rust prevention, and friction reduction, it is also called "full floating bearing".
全浮式轴承与转子轴和壳体轴承之间均有间隙，当转子轴高速旋转时，具有0.25～0.4MPa压力的润滑剂充满这两个间隙，使浮动轴承在内外两层润滑剂中随转子同向旋转，但其转速却比转子轴低得多，从而使轴承相对轴承孔和转子油的相对线速度大幅度下降。由于有双层润滑剂膜可以同时进行双层冷却和润滑及清洗，并伴随产生双层阻尼。因此可知，全浮动轴承具有高速轻载，工作可靠，只传递转矩不承受任何反力和弯矩的工况；但同时，全浮动高速轴承对润滑剂要求也非常苛刻。润滑剂润滑剂必须有较好的粘—温特性，高速抗氧化安定性，抗磨性，抗剪切性，良好的导热性，清洗性，热容量大，流动扩散性、抗氧防腐性，低摩擦性，不含锌，适用于各种合金运动副。There are gaps between the full floating bearing, the rotor shaft and the housing bearing. When the rotor shaft rotates at high speed, the lubricant with a pressure of 0.25-0.4 MPa fills the two gaps, so that the floating bearing is in the inner and outer layers of lubricant. The rotor rotates in the same direction, but its speed is much lower than that of the rotor shaft, so that the relative linear velocity of the bearing relative to the bearing hole and the rotor oil is greatly reduced. Due to the double-layer lubricant film, double-layer cooling and lubrication and cleaning can be carried out simultaneously, and the accompanying double-layer damping is produced. Therefore, it can be seen that the full floating bearing has high speed and light load, reliable operation, and only transmits torque without bearing any reaction force and bending moment; but at the same time, the full floating high speed bearing has very strict requirements on lubricants. Lubricants Lubricants must have good viscosity-temperature characteristics, high-speed anti-oxidation stability, wear resistance, shear resistance, good thermal conductivity, cleanability, large heat capacity, flow diffusion, anti-oxidation and corrosion resistance, low Frictional, zinc-free, suitable for all kinds of alloy kinematics.
