Abstract

Roller bearing compressor comprising a central cylindrical rotor 1 having regularly spaced projections 2 turning in a cylindrical stator 5 with the minimum of play. One or more cylindrical planet wheels 6 roll with no gear ratio on a central rotor 1 and turn with a slight play in the counterbores 7 of the stator. This or these planet wheel(s) (6) carry/carries an axial recess 8 permitting the passage of each projection 2 of the central rotor 1. The gas to be compressed arrives through the openings 9 of the stator downstream of the planet wheel(s) (6). The compressed gas leaves through the openings 24 of the stator upstream of 6, which are marked during the compression phase by the solid part of the distribution discs 23 mounted coaxially at the ends of each planet wheel 6.

Description

Il est connu de réaliser des compresseurs rotatifs comportant au moins deux rotors dont les surfaces sont constamment très près l'une de l'autre et tournant à l'intérieur de cylindres circulaires.It is known to produce rotary compressors comprising at least two rotors whose surfaces are constantly very close to each other and rotating inside circular cylinders.

I1 est connu également de réaliser ces rotors avec une forme helicoidale et de réaliser ainsi un flux axial, l'aspiration se faisant à une extrémité et le refoulement à l'autre.  I1 is also known to produce these rotors with a helical shape and thus achieve an axial flow, the suction being done at one end and the discharge at the other.

Ces compresseurs qui sont sn général bruyants ne peuvent fonctionner à sec et nécessitent des machinss spéciales pour leur-usinage.These compressors, which are generally noisy, cannot operate dry and require special machines for their machining.

L'invention objet du présent brevet supprime ces inconvénients.The invention which is the subject of this patent eliminates these drawbacks.

Elle est caractérisés en ce qu'un rotor principal cylindrique tournant à l'intérieur d'un stator cylindrique porte des saillies sensiblement demicylindriques ou non, qui présentent le jeu minimum avec le stator, un ou plusieurs satellites cylindriques étant disposés à la périphérie du dit rotor sur lesquels il -ou ils- roule sans vitesse relative, le -ou lesdit satellite portant un évidement axial demi cylindrique ou non, permettant le passage des saillies du rotor.It is characterized in that a cylindrical main rotor rotating inside a cylindrical stator carries substantially semi-cylindrical projections or not, which have the minimum clearance with the stator, one or more cylindrical satellites being disposed at the periphery of said rotor on which it -or they- rolls without relative speed, the -or said satellite carrying an axial recess semi-cylindrical or not, allowing the passage of the projections of the rotor.

L'aspiration et la compression se font ainsi sans engrenement, sans vitesse relative autre qu'à la périphérie, avec des surfaces simples d'usinage facile.Aspiration and compression are thus gearless, without relative speed other than at the periphery, with simple surfaces of easy machining.

Les saillies sur le rotor peuvent être helicoldales ainsi que la gorge de chaque satellite pour réaliser un flux axial.The protrusions on the rotor can be helical as well as the groove of each satellite to achieve an axial flow.

Le meilleur compromis entre nombre de saillies et nombre de satellites est selon l'invention trois saillies également espacées et deux satellites diamXtralement opposés.The best compromise between number of projections and number of satellites is according to the invention three equally spaced projections and two diamXtrally opposite satellites.

D'autrss caractéristiques de l'invention seront précisées au cours de la description qui suit donnée uniquement comme exemple de réalisation. Other characteristics of the invention will be specified during the description which follows, given solely as an example of embodiment.

A la planche 1-1 est représenté un compresseur à roulement selon l'inven- tion, cylindrique avec rotor à trois saillies et deux satellites.On board 1-1 is shown a rolling compressor according to the invention, cylindrical with rotor with three projections and two satellites.

La figure 1 est une coups suivant AA de la figure 2 par un plan perpendiculaire aux axes.Figure 1 is a stroke along AA of Figure 2 by a plane perpendicular to the axes.

La figure 2 est une coups suivant BB de la figure 1 par un plan contenant l'axe du rotor et les axes des deux satellites.Figure 2 is a stroke along BB of Figure 1 by a plane containing the axis of the rotor and the axes of the two satellites.

La figure 3 est une vue détachée d'un disque de -distribution.Figure 3 is a detached view of a distribution disk.

Le rotor principal (1) de contour extérieur cylindrique de révolution porte à sa périphérie les trois saillies sensiblement demi-cylindriques (2] régulièrement réparties, c'est-à-dire, que leurs axes sont à 1200 sur le cylindre extérieur du rotor.The main rotor (1) of cylindrical outer contour of revolution carries at its periphery the three substantially semi-cylindrical projections (2) regularly distributed, that is to say, their axes are at 1200 on the outer cylinder of the rotor.

Ce rotor (1) porté par les tourillons (3) et (4) tourne à l'intérieur du stator cylindrique (5), de manière telle que le sommet des saillies -(2) possède le minimum de jeu.This rotor (1) carried by the pins (3) and (4) rotates inside the cylindrical stator (5), so that the top of the projections - (2) has the minimum of play.

Les satellites (6) diamètralement opposés roulent sans vitesse relative et sans jeu sur la partie cylindrique du rotor (1). Ces satellites (8) tournent avec le minimum de Jeu dans les alésages cylindriques (7) opposés du stator t53. The diametrically opposite satellites (6) run without relative speed and without play on the cylindrical part of the rotor (1). These satellites (8) rotate with the minimum clearance in the opposite cylindrical bores (7) of the stator t53.

Les satellites (6) portent chacun un dégagement (8) sur un tiers de cylindre, afin de permettre le passage de chaque saillie sensiblement cylindrique (2) quand elle arrive en face du dit satellite.The satellites (6) each carry a clearance (8) on a third of the cylinder, in order to allow the passage of each substantially cylindrical projection (2) when it arrives opposite the said satellite.

Chaque saillie (23 se comporte ainsi comme un piston rotatif et chaque satellite (6) comme une culasse qui s'escamote au passage de la dite saillie (2).Each projection (23 thus behaves like a rotary piston and each satellite (6) like a cylinder head which retracts when said projection (2) passes.

Dans la rotation de (1) l'arrière de chaque saillie (2) effectue l'aspira- tion et l'avant de chaque saillie E23 effectue la compression.In the rotation of (1) the rear of each projection (2) performs the suction and the front of each projection E23 performs the compression.

L'aspiration s'effectue par les ouvertures (9) ménagées dans le stator (5).The suction is carried out through the openings (9) made in the stator (5).

Les tourillons (3) et (4) du rotor [13 tournent avec le minimum de Jeu dans les portées (10) et (11) des faces de fermeture t123 et (13) du stator (5).The pins (3) and (4) of the rotor [13 rotate with the minimum clearance in the surfaces (10) and (11) of the closing faces t123 and (13) of the stator (5).

Ces faces de fermeture du stator (5) portent également les paliers (14) et (15) des satellites (6). These closing faces of the stator (5) also carry the bearings (14) and (15) of the satellites (6).

Dans ces paliers (14) et (15) tournent sans jeu les tourillons (16) et (17) de chaque satellite (6) fixes sur le satellite par la tige filetée (18) et les rondelles (19) et écrous (20). L'orientation des tourillons (16) et t173 est assurée par les goupilles cylindriques ajustées (21) et (22).In these bearings (14) and (15) rotate without play the pins (16) and (17) of each satellite (6) fixed on the satellite by the threaded rod (18) and the washers (19) and nuts (20) . The orientation of the pins (16) and t173 is ensured by the adjusted cylindrical pins (21) and (22).

Entre chaque tourillon (16) ou (17) et chaque satellite est emprisonné concentriquement le disque de distribution (23) qui se trouve immobilisé et orienté par les mêmes fixations ajustées pour les tourillons (16) et (17).Between each pin (16) or (17) and each satellite is concentrically trapped the distribution disc (23) which is immobilized and oriented by the same fixings adjusted for the pins (16) and (17).

Le gaz comprimé par la partie avant des saillies (2) s'échappe par les ouvertures latérales (24) diamètralement opposées dans les faces de fermeture du stator (12) et (13).The gas compressed by the front part of the projections (2) escapes through the side openings (24) diametrically opposite in the closing faces of the stator (12) and (13).

Le disque de distribution t233 porte la lumière t253 réalisée d'une manière telle qu'elle découvre t243 dès que la pression est atteinte et qu'elle ferme dès que la saillie arrive dans le satellite. The distribution disc t233 carries the light t253 produced in such a way that it discovers t243 as soon as the pressure is reached and that it closes as soon as the projection arrives in the satellite.

Chaque ouverture (24) dans les faces de fermeture (12) et [13) du stator t5) communique avec les brides de refoulement (26) d'où le gaz comprimé est convenablement collecté.Each opening (24) in the closing faces (12) and [13) of the stator t5) communicates with the discharge flanges (26) from which the compressed gas is suitably collected.

Le rotor t1) et les satellites (8) sont synchroniséspar les engrenages (27) et (26). L'engrenage t27) monte classiquement sur le tourillon du rotor (1) a un diamètre primitif et égal au diamètre de la partie cylindrique du rotor (1). De même les engrenages (26) montes classiquement sur les tourillons t173 des satellites (6) ont un diamètre primitif égal au diamètre de la portee extérieure cylindrique du dit satellite c'est-àdire le tiers du diamètre de la portée cylindrique du rotor (1).The rotor t1) and the satellites (8) are synchronized by the gears (27) and (26). The gear t27) conventionally mounts on the journal of the rotor (1) has a pitch diameter and equal to the diameter of the cylindrical part of the rotor (1). Similarly, the gears (26) conventionally mounted on the t173 pins of the satellites (6) have a pitch diameter equal to the diameter of the cylindrical outer surface of said satellite, that is to say one third of the diameter of the cylindrical surface of the rotor (1 ).

Afin d'éviter des usinages difficiles les faces internes des fermetures (12) et (13) du stator (5) sont planes et elles portent interposées les plaques (29) portant chacune trois ouvertures circulaires savoir
Deux diamètralement opposées du diamètre des disques t23) de distribution et une centrale du diamètre des paliers du rotor (11.In order to avoid difficult machining, the internal faces of the closures (12) and (13) of the stator (5) are flat and they interpose the plates (29) each carrying three circular openings, namely
Two diametrically opposite the diameter of the distribution discs t23) and a central one the diameter of the rotor bearings (11.

Le fonctionnement du compresseur à roulement se comprend aisément dans la rotation du rotor t1) les capacités en avant des saillies (2) diminuent de volume et les capacités en arrière des saillies (2) augmentent de volume.The operation of the rolling compressor is easily understood in the rotation of the rotor t1) the capacities in front of the projections (2) decrease in volume and the capacities behind the projections (2) increase in volume.

Il y a donc trois aspirations par tour à chaque ouverture t93. De même il y a également trois refoulements par tour par les ouvertures (241, le refoulement étant permis par le passage de l'ouverture (25) du disque de distribution t23) devant (24).There are therefore three aspirations per revolution at each t93 opening. Likewise there are also three upsets per turn through the openings (241, the upsetting being allowed by the passage of the opening (25) of the distribution disc t23) in front (24).

Le compresseur à roulement est décrit sous une forme de réalisation cylindrique rectiligne, parce qu'il est d'un usinage très simple.The rolling compressor is described in a straight cylindrical embodiment, because it is very simple to machine.

Il est cependant des applications dans lesquelles le flux continu axial est préférable. Pour ce cas. selon l'invention les saillies t2) sont hélicoldales ainsi que les évidements (8) des satellites (6).There are, however, applications in which axial continuous flow is preferable. For this case. according to the invention the projections t2) are helical as well as the recesses (8) of the satellites (6).

L'aspiration se fait alors par deux ouvertures diamètralement opposées sur la face amont en aval des satellites et le refoulement se fait par deux ouvertures opposées à l'amont des satellites sur la face aval. The suction is then made by two diametrically opposite openings on the upstream face downstream of the satellites and the discharge is made by two openings opposite the upstream of the satellites on the downstream face.
