Definitions

  • the present invention relates to a volumetric machine with planetary movement.
  • Machines of this type are in fact known, for example the document DE 42 09 607 describes a volumetric machine comprising a rotor having roughly the shape of a figure eight, that is to say the shape of a Roots pump rotor, which describes a planetary movement inside a stator: the axis of the rotor describes a circle, while it also rotates in opposite directions around its axis.
  • the stator has a profile having three lobes forming three chambers each equipped with an inlet and outlet valve.
  • the object of the present invention is to provide a drive device for machines with planetary movement, without mechanical bearings, and therefore perfectly suitable for dry machines.
  • the subject of the invention is therefore a volumetric machine with planetary movement comprising a cylindrical piston of axis ⁇ p , rotary and situated in a cylindrical capsule of axis ⁇ c , said piston having, in a plane perpendicular to its axis ⁇ p , a section having S p axes of symmetry, said capsule defining a hollow volume, the section of which, by a plane perpendicular to its axis ⁇ c , has S c axes of symmetry, S p and S c differing by one, the axes ⁇ p and ⁇ c parallel, being separated by a distance E, the piston and the capsule delimiting between them at least three chambers, and the capsule comprising at least one suction inlet and one discharge outlet, characterized in that it further comprises a ferromagnetic pinion of axis ⁇ p secured to the piston and comprising N p teeth, disposed inside a ferromagnetic crown of axis ⁇ c
  • the subject of the invention is also a volumetric machine with planetary movement comprising a cylindrical piston of axis ⁇ p , rotary and located in a cylindrical capsule of axis ⁇ c , said piston having, in a plane perpendicular to its axis ⁇ p , a section having S p axes of symmetry, said capsule defining a hollow volume, the section of which, by a plane perpendicular to its axis ⁇ c , has S c axes of symmetry, S p and S c differing by one, the axes ⁇ p and ⁇ c , parallel, being separated by a distance E, the piston and the capsule delimiting between them at least three chambers, and the capsule comprising at least one suction inlet and one discharge outlet, characterized in that '' it further comprises a ferromagnetic ring of axis ⁇ p , of external diameter D 1 , integral with the piston, disposed at the interior of a ferromagne
  • the machine comprises a magnetic axial stop composed of at least one pair of magnetized rings, linked, one to the fixed part and the other to the mobile part.
  • FIGS 1, 2 and 3 show three profiles among the many possible profiles of piston and capsule according to the invention.
  • Figure 4 shows schematically in section through a plane containing the two axes ⁇ p and ⁇ c , a machine according to the invention.
  • FIG. 5 is a section on V-V in FIG. 4.
  • Figure 6 is a section on VI-VI of Figure 4.
  • Figure 7 is a variant, according to a view according to that of Figure 6, in which the pinion is replaced by a simple ferromagnetic ring.
  • FIG. 8 is a variant in a view corresponding to FIG. 4.
  • FIG. 9 is a section along IX-IX of FIG. 8.
  • Figure 10 is a section along X-X of Figure 8.
  • FIGS 11, 12 and 13 show three variants of part of Figure 4.
  • the machine comprises a cylindrical piston with axis ⁇ p and a cylindrical capsule with axis ⁇ c .
  • the axes ⁇ p and ⁇ c are parallel and distant by a value E.
  • the cylinder defining the shape of the piston has an order of symmetry with respect to its axis ⁇ p equal to S p , that of the capsule an order of symmetry equal to S c ; S p and S c are chosen so that these values differ by one.
  • the geometry of the piston and of the capsule is chosen so that there is direct correspondence between these elements.
  • One of the organs, capsule or piston has a profile P 1 which identifies with a curve uniformly distant from a closed hypertrochoid, having neither double point nor cusp, excluding hypertrochoids degenerated into hypotrochoids, epitrochoids or peritrochoids .
  • the P 1 profile can also be at zero distance from such a hypertrochoid and therefore identify with it.
  • the definition of hypertrochoids is specified in French patent 2 203 421.
  • the other organ has a profile P 2 which is the envelope of P 1 in a relative planetary movement defined by two circles C 1 and C 2 of centers and rays respective (0 1 , R 1 ) and (0 2 , R 2 ), these circles C 1 and C 2 being respectively integral with the profiles P 1 and P 2 and rolling over one another without sliding by internal contact.
  • machines can be derived from machines belonging to one of the four preceding families. Indeed, one can use a profile P 2 of which at least part is identified with the envelope of P 1 in its movement relative to P 2 and of which at least a part is external to this envelope in the case of families I or II and is inside this envelope in the case of families III or IV, the different parts connecting to define a closed curve.
  • Z 1 1 + S 2 Ee i k S (1-S) + R m e i k S + 1-S 2 Ee i k S (1 + S) in which Z 1 designates the affix of the generating point of the profile P 1 , each point being specified by a particular value of the kinematic parameter k whose range of variation is between O and 2S ⁇ to traverse the curve once, S is a integer which designates the order of symmetry of P 1 with respect to the origin of the complex plane and is chosen arbitrarily, E and R m are two lengths chosen freely provided that the corresponding curve has neither double point nor point of cusp, which indirectly limits the value of the E / R ratio m .
  • Figure 1 shows, in section, by a plane perpendicular to the axes ⁇ p and ⁇ c , parallel, of the piston 1 and the capsule 2, the profile of a piston and a capsule.
  • the machine shown comprises a rotor part with axis ⁇ p comprising a cylindrical piston 1, a ferromagnetic pinion 2 and a wheel 3, and a stator part with axis ⁇ c comprising a pumping cell constituting a hollow volume 4 inside of a capsule 5, a ferromagnetic ring 6 and a bearing surface 7 comprising a bore 8.
  • the axes ⁇ p and ⁇ c are parallel and distant by a value E.
  • the piston 1 and the capsule 2 delimit between them three chambers A, B and C which each comprise an inlet equipped with a valve, respectively 9, 10 and 11, located in a lateral flange 12 linked to the stator part, and an exhaust equipped with a valve, respectively 13, 14 and 15.
  • a body 16 in the shape of a crown surrounds the capsule 5 and it has a circular recess 17 which channels the three exhausts towards a single delivery orifice 18.
  • the piston 1 performs a planetary movement inside the capsule 5: the axis ⁇ p of the piston describes a circle of radius E around the axis fixes ⁇ c of the capsule while the piston turns itself around its axis ⁇ p .
  • each chamber A, B and C alternately increases and decreases according to a pulsating movement.
  • This planetary movement is produced by the pinion 2 and the crown 6.
  • the ferromagnetic pinion 2 of axis ⁇ p which is integral with the piston 1 has N p teeth 19 and it is located inside the crown.
  • ferromagnetic 6 of axis ⁇ c which is integral with the capsule 5 and which is equipped with N B electric coils 20.
  • the ratio NOT p NOT B is equal to the ratio S p S vs .
  • the coils 20 are supplied successively.
  • the successive teeth 19 of the pinion 2 will be successively attracted by the successive coils 20 successively supplied, causing the rolling with sliding of the pinion 2 in the crown 6.
  • the coils are successively supplied, that the coils can be supplied successively one by one, or else several successive coils can be simultaneously supplied and successively the next is supplied while de-energizing the first of the group supplied simultaneously.
  • the rolling is done with sliding because the ratio of the radius of the pinion 2 to the radius of the crown 6 (at the end of the teeth 19 of the pinion 2 and of the poles 21 carrying the coils 20) is different from the ratio of the number N p of teeth 19 of the pinion 2 to the number N B of coils 20 of the crown 6.
  • the bearing rings 22, 23 on the wheel 3 and 24, 25 on the bearing surface 7 frame an axial magnetic stop consisting of two magnetic rings, 26 carried by the wheel 3, and 27 carried by the bearing surface 7. These rings are axially magnetized and in reverse so as to attract. The rings are slightly set back from the level of the bearing rings.
  • FIG. 7 shows a variant of the invention.
  • This FIG. 7 is the equivalent of FIG. 6 and differs from it only by the fact that the pinion 2 is replaced by a simple ferromagnetic ring 28 without teeth.
  • the diameters D 1 and D 2 of the ring 28 and of the crown 6 are such that D 1 D 2 is different from S p S vs , a slight clearance also existing between the crown and the ring.
  • the non-slip bearing is not produced, as in the previous case, by the successive attraction of teeth to the successively supplied coils because the ratio of the number of teeth of the pinion to the number of coils of the crown was different the ratio of the rays of the pinion and the crown, but this rolling movement of the ring 28, with sliding, in the crown 6 is here simply caused by the contact of the wheel 3 in the bore 8 and on the contrary the absence of contact between the ring 28 and the crown 6. There is therefore rolling without sliding of the parts in contact: the wheel 3 in the bore 8 and the ring 28 is thus free to "roll" with sliding since there is no contact. As in the previous case, the electric coils 20 are supplied successively.
  • FIGS 8, 9 and 10 show an alternative embodiment.
  • the pinion 2 (or the ring 28) was reamed with a hole 29 of sufficient diameter not to come, during its movement, touching the outer periphery of the bearing 7 comprising the bore 8.
  • the crown 6 and the pinion 2 (or the ring 28) on the one hand and the wheel 3 and the bearing surface 7 were coplanar as seen in FIG. 4.
  • Figures 8 to 10 thus represent such a construction for a large machine where the eccentricity E between the axes ⁇ p and ⁇ c is large.
  • piston 1 which comprises at the end a ferromagnetic pinion 30 comprising N p teeth 31 while the stator part is equipped with a ferromagnetic crown 32 equipped with N B coils 33.
  • p NOT B S p S vs .
  • the machine further carries an axial stop constituted by two magnetized rings 36 and 37 carried one, 36, by the rotor assembly and the other, 37, by the stator assembly.
  • Figures 11, 12 and 13 show three variants of the embodiment of the rolling members of the wheel 3 in the bore 8 and the axial stop carried by the same elements.
  • FIG. 11 there are no added bearing rings.
  • the magnetic ring 26 is mounted on the wheel which is clamped between a shoulder and a cap 38.
  • the magnetic ring 27 is mounted in the bearing 7 between a shoulder and a cover 39.
  • FIG. 12 as in FIG. 11, there are also no added bearing rings, the bearing is made directly on the rectified surfaces of the wheel 3 and of the seat 7.
  • the magnetic rings are framed by ferromagnetic rings: 40 and 41 for the wheel 3 and 42 and 43 for the seat 7. These rings are slightly recessed in relation to the rolling surfaces.
  • the set of magnetic rings and ferromagnetic rings constitutes a passive magnetic reluctance stop.
  • FIG. 13 there are, as in FIG. 4, bearing rings 22, 23, 24 and 25 and also, as in FIG. 12, ferromagnetic rings 40, 41, 42 and 43.
