Description
Technical field
The invention belongs to air bearing technology fields, and in particular to a kind of spiral groove type dynamic pressure air thrust foil bearing.
Background technology
Bearing is an extremely important part in modern machinery and equipment, and application field is very extensive, from small-sized household electricity
Device has the presence of bearing to ship, aerospace.Component of the bearing as a core, but limits other technologies always
Development.Gas dynamic pressure foil bearing is compared with other bearings have working speed height, friction energy loss is small, service life is long and work
The features such as ambient temperature range is wide, but since working media is gas, since the compressibility of gas limits bearing capacity,
Therefore the class bearing is only used on the high speed light loading rotating machinery of aerospace field at present, especially thrust foil bearing
The weakness of low bearing capacity limits the further genralrlization application of the class bearing.Therefore, gas dynamic pressure thrust foil bearing is improved
Bearing capacity is for improving the overall performance of bearing and being necessary in the further application of industrial circle.
The content of the invention
The present invention provides one kind to improve the bearing capacity and stability of existing dynamic pressure air thrust foil bearing
Dynamic pressure air thrust foil bearing with helicla flute paillon, can be big with higher bearing capacity and better stability
The earth improves the overall performance of thrust foil bearing.
Technical scheme：
A kind of spiral groove type dynamic pressure air thrust foil bearing, including bearing block 1, bearing bottom plate 2, corrugated foil 3, flat paper tinsel
Piece 4, the flat paillon 5 with helicla flute and screw 6；
It is thin that bearing bottom plate 2, flat paillon 4 and the flat paillon 5 with helicla flute is that round-meshed circle is opened in centre
Piece, the Circularhole diameter of three are identical with the Circularhole diameter of bearing block 1；Connecting hole is provided on the bearing block 1, passes through fixed spiral shell
Nail 6 is fixedly connected with bearing bottom plate 2；The flat paillon 4 is identical with the thin rounded flakes diameter of the flat paillon 5 with helicla flute,
Less than the diameter of bearing bottom plate 2；The corrugated foil 3 is made of the ripply claw type paillon of multi-group and paillon circle, is carried
The claw type paillon of ripple is fixed on cambered paillon circle, multiple cambered paillon corrals into annulus, the diameter of annulus with
The Circularhole diameter of bearing block 1 is identical；The outside dimension of the corrugated foil 3 is identical with the diameter of flat paillon 4；Described carries spiral shell
The flat paillon 5 of spin slot is provided with multiple helicla flutes on surface；
The corrugated foil 3 is welded on bearing bottom plate 2；The flat paillon 4 is welded on corrugated foil 3；It is described
The flat paillon 5 with helicla flute align and weld together with flat 4 corner of paillon, form double-deck flat paillon；Bearing bottom plate 2, ripple
Line paillon 3, flat paillon 4 and the flat paillon 5 with helicla flute are fixed on by screw 6 on bearing block 1.
Beneficial effects of the present invention：
1) present invention combines corrugated foil, flat paillon, the flat paillon with helicla flute, collectively constitutes the axial direction of thrust bearing
Support construction, air enters from the edge of the flat paillon with helicla flute, after groove, among this special flat paillon
A gases at high pressure area is formed, makes this dynamic pressure air thrust foil bearing that there is higher bearing capacity, while thrust can be improved
Antiwhip improves the overall performance of the kinetic pressure gas thrust bearing.
2) present invention is different from traditional oil lubrication thrust bearing, is to use air as lubricant, air plays lubrication
With the effect of heat dissipation.Compared to traditional oil lubrication thrust bearing, fueller is not required, mitigates the quality of thrust bearing, it can
By property higher, simultaneously because helicla flute is provided on flat paillon, therefore than traditional air hydrodynamic thrust paper tinsel without helicla flute
Piece bearing has higher bearing capacity.

Specific embodiment
Below in conjunction with attached drawing and technical solution, the specific embodiment further illustrated the present invention.
Such as Fig. 1, a kind of spiral groove type dynamic pressure air thrust foil bearing, including bearing block 1, bearing bottom plate 2, corrugated foil
3rd, flat paillon 4, the flat paillon 5 with helicla flute, screw 6；Six structures in figure, the structure as a whole of bottom bracket 1
One " frame ", corrugated foil 3, flat paillon 4, the flat paillon 5 with helicla flute are welded on successively according to order 1. 2. 3. 4.
On bearing bottom plate 2, after be fixed on by screw 6 on bearing block 1, formed an assembly, as shown in Figure 2.
It is the structure diagram of the dynamic pressure air thrust foil bearing corrugated foil 3 such as Fig. 3.When the thrust foil bearing
After being subject to axial thrust, corrugated foil 3 is axially deformed under the action of power, and the thrust bearing is made to have certain shock resistance
Ability.It is the structure diagram of the flat paillon 4 of the dynamic pressure air thrust foil bearing such as Fig. 4, plane smoother, Ke Yiyong
To form a lubrication air film.
It is the structure diagram of the flat paillon 4 with helicla flute of the dynamic pressure air thrust foil bearing such as Fig. 5.At this
When thrust foil bearing works normally, rotor high-speed rotation, the arrow of extraneous air then as illustrated is from helicla flute
The edge of flat paillon 5 generates vortex after entering, and then forms gases at high pressure area in the intermediate region of the paillon, makes this kinetic pressure gas
Thrust foil bearing has more high bearing capacity in the axial direction, has better stability, can improve dynamic pressure air thrust
The overall performance of foil bearing.
