The invention provides a gas suspension friction-free rotation air feeding device that can provide continuous air feeding and is free from disturbing influence of the air pipes.
Description
Technical field
The present invention relates to air supporting field.
Background technology
Along with the development of science and technology, normal adopt gas lubrication to replace common mechanical lubrication, form air film in the object gap of gases at high pressure being introduced relative motion, avoid directly contact to realize frictionless motion.
The mode that air-floating apparatus forms air film is different, air supply method is also different, usually be all utilize tracheae to introduce gas in high pressure chest, but no matter adopt which kind of plenum system, tracheae all must not produce disturbing influence to air-floating apparatus, for the air-floating apparatus that some move relative to source of the gas, there is a very large difficult problem in air supporting air feed.If side is by the folding hinge plate of the vertical placement of hinge links, bottom realizes planar friction free by multiple floating cushion and launches motion, require not introduce any external force when launching, if each floating cushion introduces tracheae from outside, floating cushion moves with hinge, and steam line can produce the impact of disturbance on the motion of floating cushion, and air feed circuit is many, easily twist, bend, be wound around, be not easy to installation and maintenance; Usually by attached for air supply pipe onboard from one piece be incorporated into another block simultaneously air feed to the floating cushion this plate, but hinge plate from fit-state to expansion time can be subject to the disturbing influences such as joint tracheae is bending, winding, the expansion of interference hinge.
Summary of the invention
Bend the deficiency of the impact of disturbance in order to the tracheae solving existing air-floating apparatus, the invention provides a kind of can the rotating for air flotation device without friction of unaffected by disturbance of air pipes of air feed continuously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of gas suspension rotates feeder without friction, comprise air-bearing shafts, air supporting cover and base, described air suspension shaft sleeve is contained in air supporting cover, minim gap is there is in described air-bearing shafts and air supporting between overlapping, described air-bearing shafts is the multidiameter of one group of diameter change, the punching of described air-bearing shafts bottom center makes the wall thickness of air-bearing shafts equal, in described air-bearing shafts major diameter and smaller diameter face and stepped vertical face is evenly equipped with throttle orifice, the bottom that described floor installation overlaps in air supporting, described base and air supporting cover, high pressure chest is formed between air-bearing shafts, there is air admission hole described base lower end, described air admission hole is communicated with high pressure chest, gas outlet is arranged at described air-bearing shafts top, described air inlet/outlet is all connected with tracheae, described air supporting has put unloads pore, described gas cell distribution of unloading is distributed on major diameter face, smaller diameter face and stepped vertical face and communicate with the gap between the gentle empty boasting of air-bearing shafts, the described circle that circumferentially has unloading pore corresponding loses heart groove.
Mentality of designing of the present invention is: according to air-bearing principle, realize air-bearing and air supporting overlap between rotate without rubbing, again by adopting the mode of self gases at high pressure air feed, gases at high pressure being introduced from air supporting cover and draws from air-bearing shafts, thus realizing rotating air feed without friction.
Gases at high pressure enter high pressure chest from air supporting cover bottom air inlet, a gases at high pressure part in high pressure chest flows out air feed to next air-floating apparatus through air-bearing shafts centre bore from gas outlet, another part throttle orifice on air-bearing shafts enters in gap that air-bearing shafts and air supporting overlaps and forms air film, fraction enters in the gap of air supporting cover and air-bearing shafts, air supporting has put unloads pore, the gases at high pressure entering gap are discharged from unloading pore after damping seal, one end that air-bearing shafts overlaps gap with air supporting communicates with air, pore is unloaded in other positions, because this gap internal memory is in barometric gradient, the gases at high pressure part entered in gap by throttle orifice is flowed out from side, gap, another part is discharged by unloading pore.
Folding hinge plate is expanded to by fit-state in the process of 180 ° under the effect of hinge, be arranged on axis of rotation when two pages of folding hinge plates launch without friction rotation feeder, base, air supporting cover are fixed with one block of plate, air-bearing shafts is connected with another block plate, therefore gases at high pressure are just delivered to another block plate from one block of plate, not by the disturbance of tracheae rotoflector, overall diameter without friction rotation air feed is less than or equal to the thickness of hinge plate, avoids multiple the rotation between feeder without friction of fit-state mutually to disturb.
Because the gap precision between air supporting cover and air-bearing shafts requires very high, therefore in installation process, leave certain surplus, then make air-bearing shafts press close to air supporting cover by the gases at high pressure in high pressure chest.
Beneficial effect of the present invention is: can air feed continuously, unaffected by disturbance of air pipes.
