Embodiment 1
[0026] Such as figure 1 As shown, it is a structural configuration diagram of the gas / liquid two-phase composite rotary reference device equipped with an "I"-shaped air-floating spindle. The air-floating bushing 5 is fixed on a stable substrate such as the instrument base 7. The shaft sleeve 5 constitutes the basic structure of the air bearing shaft system. An axial and radial air film gap is formed between the air bearing main shaft 1 and the air bearing sleeve 5. When the air film gap is filled with pressurized gas, a gas bearing and Lubricated, the air-floating main shaft 1 can drive the load W to rotate in the air-floating bushing 5 . Utilizing the self-lubricating properties of the gas, the rotary motion has extremely small friction, which can ensure high displacement sensitivity of the rotary motion; the average effect of the gas film can ensure high rotary motion accuracy.
[0027] In order to overcome the axial and radial medium and high-frequency micro-vibrations of ...
Embodiment 2
[0031] Figure 4 It is a structural configuration diagram of a liquid damping system arranged at the upper end of the "T"-shaped air-floating main shaft, and its working principle and damping effect are similar to those of Embodiment 1.
Embodiment 3
[0033] Figure 5 It is a structural configuration diagram of a liquid damping system arranged at the lower end of the "T"-shaped air-floating main shaft, and its working principle and damping effect are similar to those of Embodiment 1.
