The direct problem of researching the load capacity of segment gas-static bearing is being discussed. In calculation the movement of the shaft in the bearing is considered slow comparing than the rotational velocity. Vibrations and the influence of non-stationarity are neglected. The given geometry of the bearing and the pressure of lubrication supply in the gap between the bearing and the shaft are considered initial data. The result of the calculation is the value of the resultant pressure force, applied to the bearing segments. Summing the forces the value of the static load capacity can be found. For segments that may spontaneously rotate about the joint axis, described a method of calculating the rotation angle, at which the main moment of pressure forces applied to the segment is equal to zero and the segment’s position is stable.

    Pressure Fluctuations in the Gasostatic Bearing Supply System on Supercritical Operation Mode

    This study discusses the oscillatory mode occurring in the gap between the stator and the rotor in gas- static bearing during the outflow of under expanded gas jets out of the supply system, which interacts with the surface of the rotor.
