Definitions

  • the invention relates to a rotary volumetric machine in which the capsulism is formed by a male part and a female part (tubular body) which surrounds it.
  • the external surface of the male part which we call male surface
  • the internal surface of the female part which we call female surface
  • E helical surfaces whose axes are parallel and distant by a length which we denote by E.
  • These surfaces are defined around these axes by the nominal profile which they have in any section perpendicular to the axes (straight section) and by their respective pitch P m and P f .
  • the director of the male surface which we call male profile
  • This profile is inscribed in the circular crown with center O m , width 2E and medium radius R ° m (crown containing the male profile).
  • the director of the female surface, which we call female profile has an order of symmetry (n m +1) around its center which is the point of breakthrough O f of the axis of the female surface in the plane of the profile.
  • the mean radius R ° m can be considered as the parameter determining the scale of the cross section of the capsulism and the parameter E as a shape parameter.
  • the male part is in planetary movement relative to the female part. The first rotation of this planetary movement causes the axis of the male surface to describe, at any speed ⁇ , a cylinder of revolution of radius E around the axis of the female surface.
  • TIRASPOLSKY (Hydraulic bottom motors, drilling courses, pages 258 and 259, Editions TECHNIP PARIS 15 è ): the male profile is supposed to be the curve at uniform distance D of the ordinary trochoid of order of symmetry n m and the female profile of mean radius R ° m + E is supposed to be the curve at the same uniform distance D of the ordinary trochoid of order of symmetry (n m + 1). If the uniform distance curves of ordinary trochoids were rigorously materialized, these two profits would have permanently (n m + 1) points of contact and, coming periodically in conformity along the arcs of a circle of radius D centered on the points of cusps.
  • the machines according to the invention eliminate these drawbacks by proposing male and female profiles, the association of which has new or unexploited properties.
  • the simplest method for constructing an infinitely continuous driving arc at all its points is as follows: We define a first reference segment ⁇ f1 which identifies with a line segment perpendicular in M to g M ; we define a second reference segment ⁇ f2 which identifies with an arc of circumference centered on g M at a distance R f2 from O f such that R f2 is greater than R ° m . The radius of this arc of circumference is equal to R f2 - R ° m .
  • the resulting segment identifies with a possible half-arc of conduct.
  • the closing arcs of the female profile belong to a hypertrochoid with double points, of order of symmetry (n m +1) around O * f .
  • the male and female helical surfaces of the machines according to the invention are the only surfaces found so far which can both belong simultaneously to rigid parts. They are both machinable. They also allow adaptation of the shapes to particular requirements by the richness of the definition of the male and female profiles they use.
  • the helical surfaces can degenerate into cylindrical surfaces, the reverse of the male (1 / P m ) and female (1 / P f ) steps tending towards zero. These surfaces are then entirely defined by their cross section.
  • the working chambers are closed axially by flanges and the fluid can be admitted radially into the capsulism and / or escape from it in the same way.
  • machines according to the invention are excluded those whose male profile is a hypertrochoid.
  • the closing arcs are no longer essential for closing the chambers. They can be replaced by arcs which are external to them with which the male profile no longer comes into contact.
  • the machines according to the invention lend themselves to all combinations of absolute movements allowing the relative planetary movement of the male part to be carried out relative to the female part. In fact two possibilities are of obvious practical interest.
  • the female part belongs to the stator, the surface and the female profile then being able to be qualified as stator.
  • the relative planetary movement of the male part becomes absolute and the male part constitutes the rotor of the machine.
  • the part of the stator limited by the stator surface must consist of a layer of elastomer, the thickness of this layer can be limited to a minimum, since the stator and rotor surfaces being strictly combined slip, no local deformation should be expected to compensate for a gear failure. This results in particular in a reduction and a regularization of the parasitic resistances to the movement.
  • the male part can be linked to a primary shaft coaxial with the female surface by an open kinematic chain successively consisting of an O-ring connection, an intermediate shaft and a second O-ring connection, a thrust bearing being interposed between the primary shaft and the stator to prevent any translation of the male part along its axis.
  • an open kinematic chain successively consisting of an O-ring connection, an intermediate shaft and a second O-ring connection, a thrust bearing being interposed between the primary shaft and the stator to prevent any translation of the male part along its axis.
  • this movement can result from the articulation of the male part on a bent shaft in rotoidal connection with the stator, around the axis of the female surface and the existence of a transmission ratio n m / n m +1 linking the male and female parts.
  • the male part is in rotoidal connection with a stator around the axis of the male surface and the female part is in rotoid connection with the stator around the axis of its internal surface (female surface), the relative planetary movement being imposed by a transmission of ratio n m / n m +1 connecting the male and female parts.
  • FIG. 1 recalls the construction of the current point U0 of an ordinary trochoid ⁇ ord of center O and of order of symmetry n, for a value of the configuration parameter which locates the point U0 in the vicinity of a point of reversal B0.
  • the figure also shows the construction of the point U of your curve ⁇ eq at uniform distance D from this trochoid ⁇ ord , for the same value of the configuration parameter ⁇ .
  • the turning point B0 of ⁇ ord corresponds a turning point B of ⁇ eq ; but, between U and B, the tilting of your normal g U makes inevitable the existence in ⁇ eq of another turning point U *; the curve ⁇ eq therefore has a reentrant arc U * B and the profile containing ⁇ eq which extends beyond B by a circumference ⁇ c with center B0 cannot be rigorously materialized.
  • FIG. 2 illustrates the properties imposed on the male profile 1.
  • FIG. 3 illustrates the properties of the driving arc 2 belonging to the female profile of the machine shown diagrammatically in FIG. 4.
  • the profile is constructed in the system of axes O m XY and the point U corresponds to a current value ⁇ of the configuration parameter.
  • the vector O m U results from the composition, according to equation (I), of a first vector O m V of module R ° m inclined by the angle ⁇ on the axis O m X , of a second vector VW of module 3E / 2 inclined by the angle (-2 ⁇ ) on the first and of a third vector WU of module E / 2 inclined by the angle (4 ⁇ + ⁇ ) on the second.
  • the profile is constructed in the system of axes O m XY and the point U corresponds to a current value ⁇ of the configuration parameter.
  • the vector O m U results from the composition, according to equation (I), of a first vector O m V of module R ° m inclined by the angle ⁇ on the axis O m X and of a second vector VU of module E inclined by the angle (-2 ⁇ ) on the first.
  • the normal g U in U passes through the point U1 of the circumference C pm and cuts this circumference a second time at the point U2 which determines the angle ⁇ as above.
  • FIG. 9 shows the construction of a current point C belonging to the driving arc 2 and a current point F belonging to the closing arc 3 of the female profile 23, which will come into contact at different times with the same point U of the male profit represented in FIG. 7.
  • the female profile to which the points F and C belong is plotted in the same system of axes O m XY as the male profile.
  • the vector O m C (not drawn) results from the composition, according to equation (II), of a first vector O m C3 which is the vector O m U of FIG.
  • the vector O m F results from the composition, according to equation (III), of a first vector O m F3 which is the vector O m U of figure 7 turned by the angle ( ⁇ / 3 ), of a second vector F3F4 of module E inclined by the angle ⁇ on O m X and of a third vector F4F of module E inclined by the angle (-2 ⁇ / 3) on O m X.
  • FIG. 10 shows, in the same way as FIG. 9, the construction of a current point C belonging to the driving arc 2 and a current point F belonging to the closing arc 3 of the female profile 23, which will come, at different times, into contact with the same point U of the male profile shown in FIG. 8.
  • the hypertrochoid with double points has been completely traced to which the closing arcs belong, the material part of which is limited to points such as J where they are connected to the driving arcs.
  • the non-materialized parts of the hypertrochoid appear in these figures in broken lines.
  • Figures 11 to 19 describe the very characteristic evolution of the cross section of a chamber delimited by the male and female profiles of Figures 7 and 9, in the planetary movement of the male profile relative to the female profile.
  • the section of the chamber considered is hatched in all the figures where this section has sufficient area for this to be possible.
  • the arrow in solid line symbolizes the rotation of the male profile around the center O m which is never designated, but identified by a small blackened circle.
  • the dashed line arrow symbolizes the rotation of the center O m of the male profile around the center O f of the female profile.
  • C i describes the arc of conduct i indefinitely, in one direction then in the other, while F traverses, always in the same direction, the hypertrochoid with double points, but is only material and therefore useful for closing a chamber only during the period of time in which it traverses the closing arcs and it is only shown in FIGS.
  • the point F will disappear and the point C3 will relay it to close the section of the chamber considered whose growth it will promote by turning back along its arc of conduct.
  • the section of the chamber considered is limited by the points C1 and C3 which continue to move apart from one another along the female profile.
  • the section of the chamber considered has reached its maximum. It is still limited by points C1 and C3 but compared to the movement which animated it in Figure 13, C1 has turned back while C3 is still progressing in the same direction.
  • your points C1 and C3 further limit the cross-section of the hatched chamber, but C1 and C3 approach along the female profile. The section of the room is decreasing.
  • point F reappears at the end of the closing arc at the very moment when point C1 reaches this end and stops there.
  • the section of the chamber continues to decrease.
  • point F has relayed point C1 as the end of the chamber section.
  • F has reached the top of the closing arc, points C3 and F progressing towards each other.
  • the bedroom section will soon be canceled.
  • the points F and C3 are joined and the section of the chamber has vanished.
  • Figure 20 shows an axial section in a machine according to the invention, comprising a capsulism helical, where the female part belongs to the stator - the female surface is identified with the stator surface - and where the planetary movement of the male part is therefore absolute.
  • the rotor 5 is guided in its planetary movement by the linear contacts between the stator and rotor surfaces and it is linked to the primary shaft 6 by the intermediate shaft 7 which, by means of O-rings materialized by Cardan joints 8 and 9, is linked respectively with the rotor 5 and with the primary shaft 6.
  • This primary shaft 6 is prohibited any axial translational movement of the rotor 5 by its rotoid connection with the element 10 of the stator, connection produced by the radial plain bearings 11 and 12 and the stop 13 with multiple rows of rolling elements.
  • the drilling mud which enters the capsulism through its open end section 60 exits therefrom through its open end 70 and is then directed towards the drilling tool fixed to the nozzle 14 by the threaded assembly 15, passing through the holes 16 and the bore 17 of the primary shaft.
  • Figure 21 is a full axial section at larger motor capsulism scale of figure 20, supplemented by three straight sections in this capsulism.
  • stator tubular body 4 and the rotor 5 whose respective profiles 23 and 1 appear in the transverse sections, as well as a part of the intermediate shaft 7 and its O-ring connection 8 with the rotor.
  • FIG. 22 represents in axial section part of the capsulism represented in FIG. 21, on a still enlarged scale to allow the visualization of the contact lines such as ⁇ 1 and ⁇ 2 which intersect at a point J ⁇ A . It appears that the contact lines axially point the chambers which they delimit, which is the case for all the helical machines which are the subject of the invention but is not for any other known machine of the same type where the order symmetry of the female profile exceeds that of the male profile by one.
  • Figure 23 is an axial section in a machine according to the invention, comprising a helical capsulism, where the male and female parts of the capsulism are both in rotoidal connection with the stator.
  • Figure 24 is a cross section along AA of the machine shown in Figure 23.
  • This machine is a screw compressor for gas loaded with lubricant, so that the male part 5 externally limited by the male surface 50 to which the profile belongs male 1 can directly drive the tubular body 4 internally limited by the female surface 40 to which belongs the female profile 23, without intervention of a gear external to the capsulism.
  • the stator comprising a tubular part 10, a flange 100 through the tube 101 which admits the fluid into the machine and a flange 110 through which is made, at 11, the outlet of the fluid compressed towards the outside of the machine.
  • the flange 110 obviously only appears in FIG. 23.
  • the admission of the fluid into the capsulism from the flange 100 is done by the extreme open section 60 of the capsulism and the exhaust of the compressed fluid towards the flange 110 is done by lights such as 41, open in the female surface and controlled by valves such as 42 (figure 24).
  • the flange 110 completely closes the terminal section 70 of the capsulism.
  • FIG. 25 is a section perpendicular to the axes of the male 50 and female 40 surfaces in a compressor according to the invention where the capsulism is cylindrical (in the case of degeneration).
  • FIG. 26 is a section through a plane containing the axis of the female surface 40 in this same compressor.
  • Figure 27 is a partial section in a machine according to the invention which differs from that shown in Figures 25 and 26 only by the non-materialization of the closing arcs such as 3, which are replaced by arcs such as 603 which are external to them, the contact corresponding to the closing point being no longer material.
  • This figure is an axial section of the capsulism supplemented with a cross section in the joint plane 410.
