 gas bearings.



   The present invention relates to gas lubricated bearings for rotary members.



   It has long been known that gas lubricated bearings can offer significant advantages over liquid lubricated bearings. For example, the latter are limited to relatively low rotational speeds because high speeds overheat the

 <Desc / Clms Page number 2>

 bearing and cause it to be shut down. In liquid bearings, the process fluid is often contaminated with lubricant, for example in food processing machines. In addition, the lubricant itself can be contaminated, for example by radioactive gases in nuclear installations.

   Another disadvantage of bearings lubricated by liquids is the risk of freezing blockage in low temperature installations, for example turbines, or of chemical decomposition at high temperatures. All these downsides? can be avoided in support systems, with gas-lubricated bearings.



   Unfortunately, the gas bearings used heretofore are subject to various kinds of instability phenomena which tend to prevent high speed operation even if excessive lubricating gas consumption is tolerated to obtain a firmer lubricating film.



   Two particularly annoying types of gas bearing instabilities are synchronous spinning and half-frequency or self-excited spinning. The synchronous spinning is due to a mechanical imbalance. 8i the geometrical and gravity axes of the rotating organ do not coincide,. one can observe a spin of the geometric axis because the rotors, in particular at high speeds, tend to rotate around their axo of inertia (gravity). As the rotational speed of a gas lubricated bearing is very low (in the range of 12 to 25 µm), the gap between the two axes must also be kept very low.

   This may not be a particularly serious difficulty when a simple cylindrical shaft of a part is journalled in two bearings because dynamic or even static balancing is usually required.

 <Desc / Clms Page number 3>

 sufficient to adequately reduce unbalance. But most turbomachinery rotors are very complex * and can be formed from many parts. For example, the shaft with the rotor of an air turbine used in industry consists of more than a dozen or so parts. Even if the burp is balanced initially, during operation) its various parts can move in relation to each other! 1. others and this fact has been demonstrated experimentally.



   Other causes of synchronous rotation in known gas-lubricated bearing support systems include uneven deformations of non-isotropic materials, uneven creep rate of heavily stressed rotors, under stress. uneven erosion of parts of the rotor by solids entrained in the working fluid, in dimensional instability due to aging and in the presence of thermal gradients in the rotor.



  These effects can combine to produce significant unbalance. To indicate the centrifugal forces due to possible unbalance, a gas bearing system comprising a 36.3 kg rotor whose shaft rotates at 36,000 rpm with an eccentricity of 1.27 @u is subjected to a force of unbalance greater than 635 kg. The gas film is obviously not capable of supporting this greatly increased load. Seizure therefore occurs between the shaft and the bearing.



   The other common form of gas bearing instability i.e. half-frequency or self-excited spinning is induced by the relative speed between the shaft and the nozzle or pad and is maintained by the forces. of the film of Cas who practice between them. The threshold of the circular frequency of the whirl is usually calculated as follows

 <Desc / Clms Page number 4>

   W = R # k / m, where w = spin threshold
R = whirling ratio. The usual value is 2 or more.

   This value is considered to be constant for a gas bearing and a given rotational speed, but it is a function of the geometry of the system as well as other factors. k = elastic constant of the lubricating gas film * m = mass of the rator.



   The dami-frequency uphill tournament is very troublesome because it usually occurs at a speed lower than the desired working speed and the amplitude of this whirling suddenly increases without warning. It is also estimated that in the vicinity of the critical frequency or the threshold of the self-excited spinning, the gas bearing is extremely sensitive to external excitations. During an experiment, a light knock on the bench on which the equipment: was mounted is enough to unbalance the bearing and cause immediate seizing of the bearing surfaces.



   To avoid these difficulties, various remedies have already been proposed and tested. For example, the spin ratio can be increased by breaking the symmetry of the gas film, for example by means of longitudinal grooves, non-circular holes and separate thrust pads. The firmness of the gas film can also be increased by pre-loading the parts, increasing the diameter of the shaft, bringing the radial ease to optimum dimensions and increasing the gas supply pressure. Another method is to use resonant cavities.



   All these possible remedies have their drawbacks *

 <Desc / Clms Page number 5>

 For example, the longitudinal grooves tend to decrease the tightness of the gas film and most other processes increase the consumption of lubricating gas to an uneconomical value. D @ more, these remedies do not solve the anticipated difficulties of instability due to synchronous spinning *.



   The object of the present invention is to provide an improved gas bearing which avoids the mechanical instabilities of the rotating members and which therefore ensures stability at high rotational speeds with a relatively low consumption of lubricating gas.



   It is also an object of the invention to provide an improved gas bearing which eliminates any contact between the shaft and the rotor due to synchronous spinning and self-excited or half-frequency spinning in the desired working range.



   According to the invention, there is provided a gas bearing comprising a rotor concentrically in line with a fixed organ around which or in which the rotor can rotate at a speed of at least 2000 revolutions / minute, the space between the rotor and the stationary member communicating with a passage which itself communicates with a source of pressurized gas and the stationary member being supported by a rigid support which is characterized in that resilient support means are placed between the fixed member and the rigid support.

   In the drawings, the corresponding elements of FIGS. 7 to 14 are designated by the same reference numerals for the convenience of the reader,
As shown in Fig. 1, the rotor 11 is supported on a non-rotating shaft 12 and is spaced from the latter by a film of gas placed in a narrow gap 13 which separates them, the diametrical ease between the rotor and the tree being, for example,: from 25 -u. A hole II + is formed longitudinally and, preferably, concentrically in the shaft 12 and communicates with the annular gap 13 by radial slots 15.

   The non-rotating shaft 12, as the main rigid support, is supported by resilient cushioning and support members 16, for example, cylindrical bushes made of elastomeric materials which exhibit satisfactory relaxation characteristics * such as an elastomeric silicone or a plastic material such as polyethylene or polyvinyl chloride).

   Other suitable resilient support and cushioning members 16 include leaf-type metal springs, Ball @ ville (a washer which has a convex central portion) and helical-lady) and fiber webs. Metallic or non-metallic wound in superimposed layers around an end part of the non-rotating shaft 12.

   The material chosen to manufacture the elastic cushioning and support element must be compatible with very harsh working conditions and has

 <Desc / Clms Page number 8>

 preferably a relatively high modulus of elasticity so that its creep cannot be detected. Suitable metals include stainless steel, aluminum alloys, titanium alloys and copper-containing alloys such as beryllium-copper. Another alternative elastic cushioning and support member is a magnetic suspension device using opposing magnets and electrical control circuits to maintain central alignment.

   Another resilient support member includes a smaller diameter end portion and the non-rotating shaft. The shaft 12 is supported by a secondary rigid member 17. If necessary or desirable, suitable thrust bearings may be used to hold the rotor 11 axially in place.



   The advantages of this new construction are demonstrated in a series of experiments carried out with an assembly constructed according to Fig. 1 and having the following characteristics:

Nitrogen gas is introduced through the bore 14 which communicates with the openings 15, in the annular gap,

   13 separating the outer surface of the non-rotating shaft 12 from the wall of the radially aligned passage 18 in the rotor 11. A lubricating gas pressure of 3.72 atmospheres of nitrogen is required to lift the rotor 11 from the lube. shaft 12 which has four lumens 15 of approximately 0.51 mm in diameter.

   Rotor 11 is

 <Desc / Clms Page number 9>

   driven by pressurized air delivered through orifices or nozzles and part of its moment of inertia is exchanged by means of a grooved part of the periphery of the rotor, The rotor is intentionally unbalanced to determine if this Gas bearing is useful for improving or eliminating rotor speed limitations caused by synchronous spinning.

   It can be seen that the rotor can be rotated up to 25,000 revolutions / minute without any contact or seizing occurring between the shaft and the rotor. During the experiments, a strobe is used to observe the spinning of the rotor. the shaft in the rotor, The rotor turns around its free axis or inertia instead of its axis -, geometric.



   As the rotor lletl'shaft 12 does not come into contact, even increased rotational speeds would be possible. The flexible elastic support and damping elements are replaced by rigid ones and it is found that only a maximum rotational speed of 11,000 revolutions, * / minute can be reached before contact occurs between the rotor and the shaft,, The use of a resilient flexible support for the non-rotating shaft therefore makes it possible to work at much higher speeds without contact with the rotor compared to those which can be achieved without an element. flexible elastic mounting.



   The ability of the gas bearing of the invention to increase or eliminate the threshold of the self-excited spin was determined experimentally by means of an apparatus similar to that shown in Fig. 4 and having the following characteristics. :

The maximum speed reached with the shaft which is rigidly suspended is 17,000 revolutions / minute. With the elastic suspension element of the shaft, the bearing can. be used successfully up to speeds of 50,000 revolutions $ / minute.



   In Fig. 1, the electric current is received by a stator 19 and imparts a speed of at least 2000 revolutions / minute to the rotor 11. At least part of this energy is transmitted from the rotor 11 to the gas which enters the compressor 20 through the chamber. - suction bre 20a and which leaves the compressor through the delivery chamber 20b. In this embodiment, the compressor comprises means intended to receive the rotational energy, that is to say the discharge passage 20c of the compressor 20.



  Compressor 20 may be in the form of a blower or a liquid pump which can both dissipate shaft power as a hydraulic brake.



   Alternatively, rotor 11 may be the rotor of a turbine which receives energy from a fluid such as the high pressure outlet of a gas compressor to generate electric current. This construction is essentially the opposite of that shown in FIG. 1. In this case, by the term "generator" is meant an apparatus used to generate useful electric current or to dissipate energy by electric devices such as eddy current brakes.

   This embodiment is particularly useful when using a relatively long rotor. The inner ends of these narrow gaps 23a and 23b open into a lubricating gas space 29 hollowed out, for example, on each side of the transverse axis of the coaxial passage 23 of the rotor. -The lubricating gas which enters the collecting cavity 29 is evacuated transversely through openings 30 formed in the rotor 21 in the atmosphere or is recovered for reuse - -

   The elastic metal support does not contribute significantly to the damping. It is known that, during the analysis of many vibrating systems, the damping properties of metal springs are neglected. For any set of construction parameters such as mass and firmness ratios and degrees of unbalance, the intention bearing system remained stable up to a certain speed without
