Body bearing is fixed on bearing block 8.The extension of spring cylinder paillon 2 and glide direction are opposite with 10 direction of rotation of main shaft.
A pair bearing working principle is described referring to Fig.1~2:
1) when bearing bears radial load or uniformly distributed load, sagitta variation and circumferential sliding occur for the flat foil 1 of top layer
It in load transfer to lower layer's spring cylinder paillon 2, can will twist 5 both ends of portion and paillon is arc face contact, and multi-turn classification is held
Pressure, will touch junior beyond single-stage bearing capacity range and twist, power is handed on, be equivalent to multiple twist along deformation direction
Be sequentially connected, rigidity is gradually increased, load effect is lower circumferential and radial direction deformation and slip characteristic compared with single layer elastomeric cylinder paillon 2 have compared with
It is greatly improved.Bearing capacity can be redistributed, is uniformly transferred on bearing block by the portion 5 that twists being sequentially distributed on bearing, together
When generate adaptability rigidity and damping so that undertaking that load range is wider, the axial unstable whirling motion of consumption in time and reach vibration damping
Effect.
2) it opens in rotor, stop initial stage and during main shaft 10 runs at high speed, dry friction easily occurs for axis and bearing surface, or goes out
Existing main shaft 10 tilts so that amplitude increasing, causes to wear.At installation initial stage, the portion 5 that can be twisted according to the selection of bearing capacity size is simultaneously true
Determine paillon pretightning force.Selection twists number or the more paillon of the number of plies that twists when load is larger, and provides smaller pretightning force, at this time
Bearing elastic deformation is increased to be enhanced to neutrality, prevents rigid collision；Less number or the number of plies are selected when load is smaller
Spring cylinder paillon 2 and improve preload, adjustment operating in rotation precision and support stiffness, bearing stability enhancing.
3) when bearing works normally, relative motion occurs for main shaft 10 and the flat foil 1 of top layer, when speed of related movement reaches one
When definite value, continuous pressure is generated in axle journal and bearing clearance and air-film thickness is distributed, to form one layer of complete gas
Lubricating film plays the role of supporting rotor.With the increase of revolving speed, gas lubrication film causes the deformation of the flat foil 1 of top layer after being pressurized
And sliding, the diversification of structure make spring cylinder paillon 2 generate large range of elastic deformation and sliding under load effect, are axis
It holds and provides main elastic bearing.High-speed motion generates a large amount of frictional heats between rotor and bearing simultaneously, twists as around fluid element,
Air is lubricant, plays the role of lubrication and heat dissipation, improves the overall performance of kinetic pressure gas transverse bearing.
Change the influence of parameter: the multi stage resilient support component being made of spring cylinder paillon 2 and the flat foil 1 of top layer is in bearing block
There is in 8 bearing to lift, radial deformation and the space circumferentially slid, there is good static and dynamic performance and stability.Mainly
Change by the structure of spring cylinder paillon 2, recombination arrangement and realize with the cooperation of flat foil 1.
(1) bearing rigidity and damping are adjusted by changing 5 arranged direction of portion that twists with arrangement mode.Twisting portion 5 can be by
Design requirement takes the shell mould protrusion of different densities.It such as takes parallelly distribute on, be interspersed and the balanced carrying of non-uniform Distribution
Power adjusts rigidity and Flexible change amount.Also the direction that twists that can adjust the portion 5 that twists, staggeredly combines a variety of arrangement modes, changes curved
5 supporting-point position of volume portion improves damping characteristic so as to improve foil bearing overall stiffness and Flexible change amount.
(2) local and whole to the progress of bearing bearing characteristics by suitably increasing and decreasing the quantity, density and the series that twists in the portion 5 that twists
Body is adjusted.5 quantity of portion that twists it is more polyaxial can bearing capacity more big load distribution it is more uniform, but processing is complicated when the portion 5 that twists is excessive,
Damping action makes it that axial deformation easily occur without easy glide deformation, reduces adjusting of the bearing to 10 eccentric vibrating of main shaft.One
Series of determining to twist in range increases, and gradable pressure-bearing is evenly transferred to bearing capacity on bearing block 8.But bullet when the series that twists is more
Property cylinder paillon 2 on gap increase, paillon stiffness by itself reduces, and is unfavorable for being formed that strong support runs at high speed bearing stablizes lubrication gas
Film.
Processing method and combination: spring cylinder paillon 2 generally uses copper sheet or steel plate, wherein the portion 5 i.e. shell mould that twists is convex
It rises that paillon is heated along rectangle length direction by file punching press or laser cutting bar folder and twists, guarantee that at different levels twist partly
Diameter is different, and the bottom foil after cutting containing rectangular through-hole 4 is connected with the portion of twisting 5, plays fixing element, balanced axial force and circulation heat dissipation
Effect.To prevent from opening, the stopping time occur dry friction between rotor and transverse bearing since air film has not yet been formed, there is friction damage,
Coating can be added in flat foil surfaces to reach lubricant effect.
Multi stage resilient support component provided by the present application passes through the 5 bilateral face contact of portion that twists on spring cylinder paillon 2, phase
It is contacted than the point contact in bubbling with the unilateral line of wave foil, face contact reduces the starting moment of friction of rotor, reduces rotor
With the frictionally damage of bearing surface, under less friction square, coulomb resistance is small convenient for sliding；In 10 rotation process of main shaft, knot
It is small that structure damps small energy loss；Damping action can make the portion of twisting that radial deformation only occur, and can also not only deform but also slide to enhance
Antiwhip adapts to microsize variation and larger range of bearing capacity.Portion 5 twist by the rectangular steel plates or copper that cut out
Plate multilayer twists, and free end is welded on bottom, is equivalent to arch different the twisting of diameter and is stacked together.Each layer twists, and to encircle diameter big
The rigidity minimum that twists, remaining rigidity at different levels is sequentially increased.Under lesser bearing load, top twists and deforms at first, when
It when load arrives greatly certain value, twists and is in contact with next stage, classification undertakes rigidity and load.Load is bigger, generates flexible deformation
The number of plies it is more, the rigidity of structure of bearing is bigger.The frictional heat of traditional gas bearing rotation accumulation can only pass through table on bearing block
The through-hole of face and side sheds, and the through-hole on spring cylinder paillon 2 containing mutually independent shell mould protrusion and after twisting, by changing
It bent 5 arrangement of volume portion, position etc. and change gas trafficability performance in bearing, increase is streamed increase heat exchange area, is more advantageous to
Heat loss after carrying for a long time, further increases runnability.
