液体静压轴承是依靠一个液压系统供给压力油,经过节流器进入轴承的油腔,把轴浮起在轴承中,保证了轴在任何转速(包括静止)和一定的负载下都与轴承处于完全液体摩擦的状态。因此,液体静压轴承具有较高的承载能力,摩擦阻力极低,刚度高,回转精度高,精度保持性好,寿命长等特点,因而日益被广泛地采用。目前,由于在许多机床、机械设备中广泛采用静压轴承,这对于静压轴承结构的设计和研究就日益迫切,
Hydrostatic bearings rely on a hydraulic system to supply pressurized oil to the oil chamber of the bearing through a restrictor and float the shaft in the bearing to ensure that the shaft is in bearing with the bearing at any rotational speed (including static) and under certain load Full liquid friction state. Therefore, hydrostatic bearing with high carrying capacity, low frictional resistance, high rigidity, high precision rotation, accuracy and good retention, long life and other characteristics, which are increasingly widely used. At present, due to the widespread adoption of hydrostatic bearings in many machine tools and machinery, the design and research of hydrostatic bearing structures is increasingly urgent.
