| description | The invention discloses an electric main shaft supported by a hydrostatic integrated gas bearing. The electric main shaft comprises a revolving shaft, a front radial hydrostatic integrated gas bearing, a front thrust gas bearing, a thrust color, a back thrust gas bearing, a fastening bolt, a shell, a motor rotor, a motor stator, a back radial hydrostatic integrated gas bearing and a back end cover. The electric main shaft is supported by the hydrostatic integrated gas bearing, the hydrostatic gas bearing of the bearing is supplied with air for a certain period of time till the rotor can float, the hydrodynamic effect of a dynamic pressure gas bearing is utilized by increasing the rotating speed to support a load, so that the air supply time of a static pressure gas is shortened on the basis of not changing the bearing structure, the cost is lowered, the hydrodynamic effect of the hydrodynamic gas bearing is used fully for supporting the load, the carrying force and the stability are improved, and the electric |
