Abstract
The utility model discloses a porous thrust air bearing air tap which comprises a cylinder and is characterized in that one end surface of the cylinder is provided with at least two air inlets; the other end surface of the cylinder is provided with a pressure stabilizing air cavity; each air inlet is communicated with the pressure stabilizing air cavity by virtue of a miniature hole; one end surface of the cylinder is provided with five air inlets, one air inlet is formed in the center, and the other four air inlets are uniformly formed by taking the center as the circle center. According to the porous thrust air bearing air tap provided by the utility model, the performance of the integral air membrane can be well improved, the bearing strength of the air membrane can be greatly improved, and the working efficiency can be improved.
Description
Technical field
The utility model relates to a kind of valve for porous thrust air-bearing.
Background technique
At present, for the nozzle of air-floating main shaft, mostly be the suction port of one end for being communicated with gas circuit, the other end is puff prot.When gas is from suction port enters nozzle, under the effect of pressure, from puff prot ejection, between air-floating main shaft inner sleeve and coordinated upper head plate, lower end sheet and main shaft, form one deck air film gap, make main shaft drive coupled upper head plate and lower end sheet to move.This nozzle is subject to the impact of gas flow, and the weight of contained object is limited, thereby has affected the application of air flotation technology.Simultaneously, China Patent No. is that 201020662882.5 utility model patent discloses a kind of nozzle for air-floating main shaft, nozzle is hollow solid of rotation, the endoporus of nozzle one end is communicated with gas circuit, the endoporus of the other end is puff prot, at nozzle, have the end face center of fumarole one end to have concave surface, this concave surface has formed the air chamber of air-floating main shaft.The problems such as in actual use, these valves all exist installation trouble, boring amount is many, load-bearing rigidity is little.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is to be to provide a kind of porous thrust air-bearing valve.This valve can improve the performance of whole air film preferably, has increased substantially the load-bearing rigidity of air film, has improved working efficiency.
For achieving the above object, the utility model adopts following technological scheme:
A kind of porous thrust air-bearing valve, comprise a cylindrical body, cylindrical one end is provided with the voltage stabilizing air cavity that inlet hole, the other end are provided with micro-hole and are communicated with it, and inlet hole is communicated with gas circuit, micro-hole is puff prot, it is characterized in that: cylindrical body center is evenly provided with a plurality of inlet holes.
Realizing a kind of mode of execution of the present utility model is: a cylindrical end face is provided with 5 inlet holes, and one of them inlet hole is located at center, and other four inlet holes be take center and evenly arranged as the center of circle.
Realizing a kind of mode of execution of the present utility model is: a cylindrical end face is provided with 4 inlet holes, and 4 inlet holes be take center and evenly arranged as the center of circle.
The beneficial effects of the utility model are:
The utility model is inlaid in the air supporting cover of air-floating main shaft axle sleeve, and is communicated with the gas circuit being distributed in axle sleeve.When gas is from inlet hole enters nozzle, under the effect of pressure, from puff prot, spray, and diffuse to form a gas foot at voltage stabilizing air cavity, gas is increased with the surface of contact between coordinated upper head plate, lower end sheet and main shaft, thereby produced lift of gas is increased, can improve preferably the performance of whole air film, increase substantially the load-bearing rigidity of air film, improve working efficiency.

Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
Specific embodiment 1:
A porous thrust air-bearing valve, comprises a cylindrical body, and a cylindrical end face is provided with at least two inlet holes 1 symmetrically, other end is provided with a voltage stabilizing air cavity 3, and each inlet hole 1 is communicated with by the micro-hole corresponding with it 2 and voltage stabilizing air cavity 3.
With reference to Fig. 1-Fig. 2, a kind of porous thrust air-bearing valve, comprises a cylindrical body, and a cylindrical end face is provided with 5 inlet holes 1, and one of them inlet hole 1 is located at center, and other four inlet holes 1 be take center and evenly arranged as the center of circle.Cylindrical other end is provided with a voltage stabilizing air cavity 3, and each inlet hole 1 is communicated with by the micro-hole corresponding with it 2 and voltage stabilizing air cavity 3.
Specific embodiment 2:
With reference to Fig. 3-Fig. 4, a kind of porous thrust air-bearing valve, comprises a cylindrical body, and a cylindrical end face is provided with 1, four inlet hole 1 of four inlet holes and take cylindrical body center and evenly arrange as the center of circle.Other are identical with embodiment 1.
For a person skilled in the art, can make other various corresponding changes and distortion according to technological scheme described above and design, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
