内部节流液静压内圆主轴的节流器直接加工在轴承内表面上,这样,主轴总体结构简单,可避免节流器的阻塞。此外还有以下优点:1.油腔压力的变化要比小孔节流器快;2.压力比与轴承间隙无关;3.偏心率不大时,轴承刚性高。文章介绍了主轴结构、内部节流器液静压轴承的设计计算与制造装配等。 The internal throttling hydrostatic internal diameter of the main shaft of the throttle directly processed in the bearing inner surface, so that the overall overall structure of the spindle is simple to avoid the throttle blockage. In addition there are the following advantages: 1. Oil pressure changes faster than the small orifice; 2. Pressure ratio and the bearing clearance has nothing to do; 3. Eccentricity is not large, the bearing rigidity. The article introduces the design of the spindle structure, the internal throttle hydraulic hydrostatic bearing design and manufacturing assembly.
