Abstract
The utility model provides an aerostatic bearing capable of realizing high-speed rotation. According to the aerostatic bearing, a pair of radial bearings and a pair of thrust bearings spaced by flanges bulged from a rotating shaft are used for maintaining a rotating body, and the bearings are provided with air from outside to form the aerostatic bearing.
Description
Technical field
The utility model provide use in a kind of main shaft, rotating platform or electrostatic sprayer etc. of the turbine device of changing in high peripheral velocity (high peripheral speed) can High Rotation Speed hydrostatic gas-lubricated bearing.
Background technique
In the past, use the main shaft bearing of roll type, thus, there is the problem of noise and vibration etc., and there is the problem that is difficult to High Rotation Speed.
Model utility content
The utility model taking realize can High Rotation Speed hydrostatic gas-lubricated bearing as object.
The utility model is in order to solve above-mentioned problem, and following technological scheme is provided.
(1) a kind of hydrostatic gas-lubricated bearing, it is characterized in that, the aperture surface of shell is separately installed with porous material parts cylindraceous on two positions that separate vertically, on these porous material parts across bearing play and chimericly have an axle, spray pressurized gas via porous material parts to bearing play from air vent, and, with respect to radially give prominence to the discoid flange arranging on radial direction from axle, the planar surface portion of the left and right of this flange is thrust bearing surface, forms thrust pneumatic bearing in fixed side.
(2) according to the hydrostatic gas-lubricated bearing described in technological scheme 1, turbine blade is installed on running shaft, according to the compressed-air actuated supply from fixed side and can High Rotation Speed.

Embodiment
The hydrostatic gas-lubricated bearing making the transition as this high-speed rotary in the past, for example, have hydrostatic gas-lubricated bearing as shown in Figure 1.In this hydrostatic gas-lubricated bearing, the radial bearing being made up of porous material parts 4 cylindraceous is installed on the aperture surface of shell 1.
Be preferably, between shell 1 and porous material parts 4, be provided with spaced apart and two sleeves 2 independently respectively vertically.
On these porous material parts 4 across not shown small bearing play and chimericly have an axle 5.On shell 1, be provided with air vent 6 radially, and from radial bearing sleeve 2 by and to porous material parts 4 supplying compressed gas.In addition, on axle 5, on the position between two porous material parts 4, be provided with the exhaust port 7 being communicated with axle penetration hole 5a from axle outer surface, the pressurized gas of the surface ejection from porous material parts 4 is discharged.
At a distolateral lip part 10 that is radially provided with highlightedly flange-like of axle 5, the planar surface portion 11,11 of the left and right of this lip part 10 becomes thrust bearing surface.
In each thrust bearing surface 11, respectively across not shown small bearing play and relative two thrust-bearings 12,12, be fixedly supported upon in thrust bearing shell 13 separately and lip part 10 is clamped.
Although these thrust-bearings 12 are not illustrated, these thrust-bearings 12 are also hydrostatic gas-lubricated bearings, on the thrust bearing shell 13 of the constituting component as shell 1, are respectively equipped with air vent and exhaust port.In addition, though not shown, between thrust-bearing 12 and radial bearing 4, be provided with exhaust port.
Above, form rotation freely but axial confined running shaft by a pair of radial bearing and a pair of thrust-bearing.
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.
Claims (2)
1. a hydrostatic gas-lubricated bearing, it is characterized in that, the aperture surface of shell is separately installed with porous material parts cylindraceous on two positions that separate vertically, on these porous material parts across bearing play and chimericly have an axle, spray pressurized gas via porous material parts to bearing play from air vent, and, with respect to radially give prominence to the discoid flange arranging on radial direction from axle, the planar surface portion of the left and right of this flange is thrust bearing surface, forms thrust pneumatic bearing in fixed side.
2. hydrostatic gas-lubricated bearing according to claim 1, is characterized in that, turbine blade is installed on running shaft, according to the compressed-air actuated supply from fixed side and can High Rotation Speed.
