Dense embedded type elastic porous throttling air bearing

The invention provides a dense embedded type elastic porous throttling air bearing. Comprising an outer sleeve, a main shaft, a thrust plate, a front thrust shoe, a rear thrust shoe, a radial bearing bush, thrust bearing elastic local porous throttlers and radial bearing elastic local porous throttlers, wherein the front thrust shoe and the rear thrust shoe are arranged on two sides of the thrust plate and are separated by an adjusting ring; the radial bearing bush and the rear thrust shoe are designed into a whole; the thrust bearing elastic local porous throttlers are densely embedded in the thrust shoes; and front and rear end covers. The thrust bearing and the radial bearing elastic local porous throttler are both made of elastic porous materials, are of a small-diameter circular sheet structure, and can generate elastic bending deformation in a static pressure cavity space range under the action of the pressure difference of the two sides, additional damping is provided for a bearing system, and the size
