LARGE AIR HYDROSTATIC BEARING OF THE AEROSPACE VERTICAL DYNAMIC BALANCING MACHINE WITH HARD SUPPORT

In order to meet the pressing need of the aeroscientific experments, this paper presents an air hydrostatic bearing of the low speed and the high torque stiffness. on the structural characteristics and the reliability, the paper briefly analyzes this type of bearing. We adopt the opposite bearing with two-row throttle to greatly raise the rigidity for satisfying the special requirements of the new type of vertical dynamic balancing machine with the hard support, that is: low noise, low turning speed and great stiffness of the support system. Limiting strictly the mass specific parametere of the satellites within a certain testing precision range, and assuring the attitude stability of communication satellites in space flight are the indispensable technical means of successful running of the communication satellites. The practice has proved that such kind of the method of designing is accurate and reliable for satisfying the requirements of a certain urgent engineering. It fills up the gaps in the fields of experimental equipments in China and opens up a new area in the application of the air hydrostatic bearing.
