液体静压轴承具有许多优点,它作为机床主轴的支承已有不少的应用实例,但是否能应用于高速内圆磨头呢?我厂通过试验和生产应用证明是完全可行的。一、问题的提出我厂生产的光学经纬仪中采用半运动式圆柱形轴系结构(见图1),轴系中用钢球与锥形表面接触,利用其自动定心作用减小了间隙大小对轴的晃动的影响。因此这种轴系置中精度高,并且转动摩擦力矩小,轴起动灵活,磨损小。但是轴系的加工工艺要求高,如其中的中轴φ16孔锥度不大于0.0005mm,椭圆度不大于0.001mm,90°锥面对φ16的跳动量不大于0.001mm,其椭圆度不大于0.001mm。φ16孔和锥面光洁度各为▽10和▽9(见图2)。对于 Hydrostatic bearing has many advantages, it has many applications as a spindle support, but can it be applied to high-speed internal grinding head? I plant through the test and production applications proved to be entirely feasible. First, the issue put forward I plant the optical theodolite semi-moving cylindrical shaft structure (see Figure 1), shaft with steel ball and tapered surface contact, the use of its automatic centering to reduce the gap size Impact on the shaft sway. Therefore, this shafting system with high accuracy, and the rotation of small friction torque, shaft start flexible, small wear and tear. However, the shaft of the processing requirements, such as one of the shaft φ16 taper not more than 0.0005mm, ovality less than 0.001mm, 90 ° taper of φ16 beating less than 0.001mm, the ovality of not more than 0.001mm . φ16 hole and cone finish each ▽ 10 and ▽ 9 (see Figure 2). for
