Embodiment
Fig. 1 is the sectional view of one embodiment of the present of invention.
On the aperture surface 1b of shell 1, via two O type rings 3, yielding support has a sleeve 20, and these two O type rings 3 are disposed in respectively in groove set on sleeve two end part.On the aperture surface of this sleeve 20, on two positions spaced apart vertically, be provided with the large-diameter portion 21 large with the central part phase diameter group of sleeve, in this large-diameter portion 21, be separately installed with the porous material parts 4,4 cylindraceous as radial bearing.In these two porous material parts 4,4, across not shown small bearing play and the chimeric axle 5 that has hollow.
On shell 1, on the position between two porous material parts 4, be formed with the air vent 6 running through to aperture surface 1b from outer surface of outer cover 1a.In addition, on the outer diametric plane 20a of sleeve 20, in the inner side part of two O type rings 3, be provided with the air supply chamber 23 being formed by shallow all grooves, and be provided with two vents 25,25, other the air supply chamber 24 that these two vents 25,25 form by this air supply chamber 23, with all grooves by shallow that are formed on the outer diametric plane of porous material parts 4 is communicated with.
From being located at the air vent 6 shell 1, via air supply chamber 23, vent 25, air supply chamber 24 and supply with pressurized air to porous material parts 4, and pressurized air is sprayed to bearing play from the radial bearing surface 26 of porous material parts 4.On axle 5, on the position between two porous material parts 4, be provided with the exhaust port 7 being communicated with from axle outer surface to axle penetration hole 5a, so that the pressurized air of the surface ejection from porous material parts 4 is discharged.
Next illustration.To be assembled into respectively on the large-diameter portion 21 of two positions of the aperture surface of sleeve 20 as the porous material parts 4,4 cylindraceous of radial bearing, then, process the radial bearing surface 26 of the aperture surface of these two porous material parts 4,4 simultaneously, thereby guarantee the coaxality of two radial bearing surface 26,26.Because sleeve 20 is one, guarantee the coaxality of regulation so can easily process.Therefore, the adjustment after chimeric to axle 5 and porous material parts 4 is also become easily, do not worry in the rotation of axle 5, the radial bearing surface 26 of porous material parts 4 can contact with axle 5.
In the time making this hydrostatic gas-lubricated bearing work, supply with pressurized air from the air vent 5 of shell 1.This pressurized air enters in porous material parts 4 via air supply chamber 23, vent 25, air supply chamber 24, from porous material parts 4 by and spray equably from the radial bearing surface 26 of the inner peripheral surface of porous material parts.Thus, the higher air layer of mineralization pressure in radial bearing gap, make running shaft 5 with non-contacting mode suspension bearing on shell 1.The pressurized air spraying from radial bearing surface 26 forms air film on one side radial bearing gap, and running shaft 5 is radially supported, flow out continuously to air in the gap between exhaust port and shell 1 and the axle 5 between exhaust port 7, thrust-bearing 12 and radial bearing 4 on one side.
In addition, thrust-bearing 12 also never illustrated air vent supply is had to pressurized air, from the pressurized air of the face ejection of the thrust-bearing 12 that formed by porous material parts, in bearing play between the thrust bearing surface 11 of the left and right of one of axle 5 distolateral lip part 10, the air layer that mineralization pressure is higher.Thus, running shaft 5 also supports in non-contacting mode in thrust direction.Then, pressurized air, from the exhaust port between exhaust port, thrust-bearing 12 and the radial bearing 4 of shell and the gap between thrust bearing shell 13 and axle 5, flows out in air.
As mentioned above, according to the utility model, on the aperture surface of a sleeve on the aperture surface of yielding support at shell via O type ring, be separately installed with vertically two porous material parts cylindraceous spaced apartly, on these porous material parts across bearing play and chimericly have a running shaft, thus, can be under the state being arranged on general sleeve, process the radial bearing surface of the porous material parts that arrange discretely vertically simultaneously, thereby can guarantee the coaxality of two bearing surfaces.This result is, in bearing working, can prevent in two bearing surfaces any one and be coupling tactile phenomenon, in addition, also can realize and makes the assembling of two porous material parts and adjust the effect that operation is simplified.
And, four O type rings can be reduced to two, thereby can be reduced the effect of number of components.
As mentioned above, form rotation freely but axial confined running shaft by a pair of radial bearing and a pair of thrust-bearing that are kept by elastomer.
Though not shown, by the drive unit that can rotate is installed in outside, and can form the main shaft that can freely rotate.
For example, mounting turbine blades on running shaft, can be by extraneous gas High Rotation Speed, if bell cup (bell) etc. is installed on solid of rotation front end, can form electrostatic sprayer.
