Definitions

  • the invention relates to the field of engineering, in particular, to rotary piston pumps, compressors, hydraulic motors and internal or external engines (steam boiler) of heat input used in stationary installations or on vehicles.
  • the disadvantage of this device is the inability to provide effective lubrication of the contact points of the inner surface of the housing with three radial compression plates located in the grooves of the rotating rotor, which causes intensive wear of the compression plates and the need for complex replacement with dismantling of the rotor.
  • the closest to the claimed invention in technical essence and the achieved result is a device (see SU JYI. 1694986, CL. F04C 2/18, 11/30/1991), which contains a housing with channels for supplying and discharging a working medium with end caps, a hollow profiled rotor eccentrically mounted in the housing with a ring gear on its inner surface, and a synchronization mechanism made in the form of a pinion gear mounted on drive shaft, and gears mounted on an additional shaft, with the possibility of their interaction with the gear rim of the rotor, which in cross section is made in the form of a curved shape, the length of the segment formed between the points of the per section line passing through the centers of the driving and additional gears with the envelope of the profile remains unchanged when the rotor is rotated, and the inner surface of the rotor has a profile corresponding to the outer envelope.
  • the technical result to which the invention is directed is the possibility of increasing the rotor speed by reducing friction and dynamic loads on the nodes of the rotor machine, which greatly expands the possibilities of its application in quality of pumps, compressors, hydraulic motors and volumetric engines.
  • the technical result is achieved due to the fact that in the described device the rotor does not move on the gears, but on solid roller wheels that are parallel to the gears and roll on the smooth inner surface of the rotor with less friction as compared to the gear transmission. Moreover, the radius of the wheel-rollers and gears is less than the radius of a small segment of the gear rim of the rotor, as a result of which when changing the instantaneous axis of rotation of the rotor a full “frontal” impact of the small segment on the gear does not occur and the transmission of rotor torque to the shafts will be quite smooth.
  • a good example of such an effect is the free rolling of a heavy metal ball over a solid surface on which there are shallow spherical recesses.
  • the ball by inertia gradually rolls and rolls out of it; if the radii coincide, then the ball rolls into the recess with a blow over the entire surface and can stop in it, transferring all the energy.
  • a rotary machine with offset shafts comprising a housing with compression plates, channels for supplying and discharging the working medium and end walls, a hollow profiled rotor eccentrically mounted in the housing with a gear ring on its inner surface and a synchronization mechanism made in the form of gears mounted on two shafts with the possibility of their interaction with the ring gear of the rotor, which in cross section is made in the form of a curved figure, the length of the segment formed between the points of intersection of the straight line, passing through the shaft centers, with the envelope of the profile remains unchanged when the rotor is rotated, and the inner surface of the rotor has a profile corresponding to the outer the envelope, while the rotor machine additionally contains round wheels-rollers mounted parallel to the gears, and the rotor for them contains smooth grooves on the inner surface, supported by rolling the rotor inside the housing with the least friction.
  • Roller wheels have a radius smaller than the radius of the inner envelope of a small segment of the rotor and can be mounted symmetrically to the gears on both shafts or on their half shafts mounted on the end walls of the device.
  • Gears contain at least one tooth less than six times the number of teeth on a small segment of the rotor and, to avoid mutual contact, can be shifted relative to each other on shafts on which flywheels are mounted for uniform rotation.
  • both shafts are offset relative to the instantaneous axis of rotation of the rotor in a plane passing through the center lines of the compression plates mounted on the housing with the possibility of replacing them without dismantling the end walls, for which both shafts are parallel offset in opposite directions in the plane, passing through the center lines of the compression plates installed in the body of the rotary machine.
  • FIG. 1 shows a profile of a rotor generatrix.
  • FIG. 2 shows a cross section of a device.
  • FIG. 3 shows a longitudinal section of the device.
  • FIG. 4 - 7 are diagrams of rotor position in dynamics. The best embodiment of the invention
  • the rotary machine with offset shafts comprises a housing 1, in the slots of which two spring-loaded compression plates 2 are installed with the possibility of replacing the end walls 4 without dismantling.
  • a rotor 6 In the housing 1 with the inlet and outlet channels 3 of the working medium, a rotor 6 having a gear ring 7 and grooves 8 around the entire perimeter of the inner surface.
  • the ring gear 7 is meshed with two gears 9 mounted on the shafts 10 with the flywheels 11.
  • the outer and inner envelopes of the rotor 6 have a profile that is formed of three pairs of opposite to each other each other large and small segments (60 °) of circles with centers at the vertices of an equilateral triangle, depicted by dashed lines (see Fig. l).
  • Such a profile during the movement of the rotor 6 inside the housing 1 ensures the immobility of the compression plates 2 and the permanent engagement of the ring gear 7 with two gears 9 of the shafts 10 mounted on bearings in the end walls 4, because the distance between the contact points of the rotor 6 with the upper and lower compression plates 2 is constant during rotation of the rotor 6 and this distance is equal to the sum of the radii of the small and large segments of the outer envelope of the rotor 6.
  • Compression plates made, for example, of aluminum-graphite alloy or fluoroplastic, have a rectangular shape and sufficient height for long-term work. The device operates as follows.
  • the gears 9 will rotate more than 60 ° on their shafts, as their axis of rotation does not coincide with the axis of rotation of the rotor 6 and the radius of the gears is less than the radius of the small segment and the radius of the large segment of the rotor 6.
  • the upper gear gears to the large segment of the rotor, the lower gear to the small segment , and the rotor begins to move to the right, rotating 60 ° around the center (instantaneous axis of rotation of the rotor) of the circles of small and large segments, i.e. around the bottom of the dashed triangle (Fig.7).
  • the cooling and lubrication systems of the engine, as well as the drive of valves and nozzles, can be of any known design and are not shown in the figures.
  • the working volume and engine power are determined by the width of the rotor 6 and the value of the radii of its external envelopes.
  • the proposed rotary machine with offset shafts allows to reduce dimensions and weight due to the small number of interacting nodes, increase efficiency by reducing the friction of the rotor against the shaft housing and gears, increase specific power and productivity due to the increased rotor speed, increase the time replacement of compression plates and durability of rotary pumps, compressors, hydraulic motors and heat engines.

Abstract

Selon l'invention, une machine rotative à arbres décalés peut s'utiliser dans des pompes à pistons rotatifs, des compresseurs, des moteurs hydrauliques ainsi que des moteurs à combustion interne ou des moteurs à combustion (par exemple, utilisant une chaudière à vapeur), utilisés dans des installations ou des véhicules. La machine rotative à arbres décalés comprend un boîtier (1) et un rotor profilé (6) avec une couronne dentée (7) réalisée à sa surface interne, de même qu'un mécanisme de synchronisation se présentant comme deux engrenages (9) montés sur les arbres de travail (10) de manière à pouvoir interagir avec la couronne dentée (7) du rotor (6). La machine rotative comprend en plus des roulettes rondes (5), et le rotor (6) comporte des cannelures lisses (8) destinées à ces roulettes et réalisées à la surface interne, sur lesquelles s'appuie mobile le rotor (6) qui fait des rotations à l'intérieur du boîtier (1), le frottement étant réduit au minimum. Afin de réduire les forces d'inertie et d'assurer un endentement permanent des engrenages (9) avec la couronne dentée (7) du rotor (6), les deux arbres (10) sont décalés en parallèle dans des directions opposées dans un plan qui passe par les lignes centrales des plaques de compression (2), montées dans le boîtier (1) et pouvant être remplacées sans retrait de rotor (6). Par conséquent, il est possible d'augmenter le nombre de tours du rotor (6) par la réduction du frottement et des charges dynamiques sur les unités de la machine rotative, ce qui élargit sensiblement les possibilités de l'utilisation de la machine en tant que pompe, compresseur, moteur hydraulique ou moteur de type volumique.
