Definitions

  • the invention relates to a turbomolecular pump according to the preamble of claim 1.
  • turbomolecular pumps have been used in vacuum technology to produce high vacuum and ultrahigh vacuum.
  • the vacuum generation is based in them on a rotor with a plurality along the rotor axis staggered blade rings, between which stator side standing blade rings are arranged.
  • stator blade rings are known in the art.
  • so-called sheet metal stator disks are considered. These are typically made of thin sheet metal by first exposing the blades of the blade ring by punching or cutting and then turning them out of the disk plane in a subsequent forming step.
  • These Blechstatorsayn are inexpensive and are particularly popular in the field of Vorvakuums in which the blades are exposed only by a few degrees from the disk plane.
  • the EP 967 395 A2 shows such a BlechstatorMIC.
  • each stator-side blade ring is arranged around the shaft of the rotor and usually between two rotor-side blade rings, the assemblability of forming the Blechstatorsay one stage of several, usually two, part discs to form.
  • the small thickness of the sheet becomes a disadvantage: where the part discs abut each other, the thin sheets can slide over each other.
  • the blades of the blade ring are then positioned incorrectly and deviate among others in the direction of the rotor axis from its desired position.
  • the gap between the rotor-side and stator-side blade ring is used up. In special operating conditions, for example at high gas loads can lead to a contact between the rotor-side and stator-side components. In the worst case, the failure of the pump is the result.
  • stator disc has two partial disks and that the contacting abutting edges of the partial disks are shaped in such a way that they collide in a crossed manner at least in sections. This can be effected by unscrewing at least a portion of the abutting edge of the disc plane. As a result, an overlapping of the part discs is prevented, the unscrewing can take place in the already necessary forming step in which the blades are rotated out of the disk plane. It is only a processing of the forming tool necessary.
  • Fig. 1 It has a flange 4 which is releasably secured to the flange of a chamber to be evacuated. Through the suction port 6 gas is sucked into the pump and discharged through the outlet 8. In the housing 2 rotor 10 and stator 20 are angordnet, by the interaction of the conveying effect is achieved.
  • the rotor comprises a shaft 12 on which a fore vacuum side rotor disk 14, a central rotor disk 16 and a high vacuum side rotor disk 18 are provided, each of the rotor disks having a blade ring consisting of a plurality of blades.
  • the shaft is rotatably supported on the high vacuum side by a permanent magnet bearing 40 and on the fore vacuum side by a roller bearing 42.
  • a drive 44 translates the rotor into rapid rotation of tens of thousands of revolutions per minute.
  • the stator includes a forward vacuum-side stator disk 24, a middle stator disk 26, and a high-vacuum-side stator disk 28. These are axially spaced apart from each other by spacer rings 30, 32, and 34 with respect to the shaft and are alternately arranged with the rotor disks.
  • the stator discs also have blade rings.
  • the number of rotor and stator disks depends on the desired vacuum parameters, such as suction capacity and pressure ratio between intake opening and outlet.
  • the rotor may be constructed instead of discs also known in the art bell design, also both bearings can be arranged on the vacuum side.
  • the stator disc has an outer support ring 50 and an inner support ring 60.
  • a first support ring portion 52 of the outer support ring is part of the first part disc 140, a second support ring portion 56 is part of the second part disc 142.
  • the support ring 60 has a first inner support ring portion 62 which is part of the first part disc, and a second inner support ring portion 66 which Part of the second part of the disc is.
  • Blades 48 are attached to inner and outer support ring and form a blade ring.
  • the support ring sections 52 and 56 or 62 and 66 abut each other in the assembled state at abutting edges.
  • the abutting edges 54 and 58 and 70 and 72 of the outer support ring portions and the abutting edges 64 and 68 and 74 and 76 of the inner support ring portions are in contact.
  • the area of the support ring sections 52 and 56 is shown.
  • the support ring sections define a disk plane 200.
  • the blades 48 are tilted, the angle of attack 202 between the blade plane and the disk plane depending on the pressure range in which the disk is used.
  • the angle of attack between the high-vacuum side and the fore-vacuum side decreases.
  • the abutting edges 54 and 58 are also inclined towards the disk plane, wherein the tilting is preferably in opposite directions, so that the abutting edges intersect. This cruising turns into one Overlapping effectively prevented by very simple means, since the tilting of the abutting edges can be done in a single operation with the unscrewing of the blades from the disk plane.
  • the 4 and 5 show the side view of a part disc from the direction of the shaft.
  • abutting edges 54 and 70 of the outer support ring portion are inclined against the disk plane 200 while the abutting edges 64 and 74 of the inner support ring portion are in the disk plane. It is advantageous to incline both abutting edges 54 and 70 in the same direction against the disc plane. This makes it possible to make symmetrical both partial discs and at the same time to achieve protection against overlapping.
  • the partial disk shown can be used both as a partial disk 140 and as a partial disk 142, so that the number of different parts in the turbo pump reduces and assembly errors are avoided.
  • Fig. 5 are the abutting edges 72 and 58 of the outer support ring portion in the disk plane 200, while the abutting edges 76 and 68 of the inner support ring portion are inclined in the same direction against the disk plane.
  • both the abutting edges of the inner and outer support ring portions may be inclined against the disk plane, thereby increasing the security against overlap.
  • a recess 80 is incorporated, so that the abutting edges 54 and 56 of two part discs engage each other after assembly. It is advantageous to select the width 204 of the recess only slightly larger than the thickness 206 of the dividing disk, since this causes precise positioning of the dividing disks relative to each other.
  • the recess has chamfers 82, so that the recess widens in the direction of the abutting edge.
  • the chamfers cause a guide of the support ring sections during assembly, whereby a centering takes place.
  • Another development provides to provide recesses on both part discs, which causes a particularly good locking of the support ring sections.
  • the first training is in Fig. 7 in a front view and in Fig. 8 represented in a partial top block.
  • the inner support ring portion 62 ' is designed to be used over its length.
  • the abutting edges 64 'and 74' are inclined in the same direction against the disk plane 200.
  • the vanes 48 of the dividing disc are connected by webs 84, which lie in the disc plane, with the inner support ring portion.
  • the neutral fiber 88 of the utilization that is to say the region of the supporting ring section which lies in the plane of the pane over the entire length of the supporting ring section, lies substantially on the edge of the supporting ring section with which the webs are connected.
  • the second training is in Fig. 9 in a front view and in Fig. 10 represented in a partial top block.
  • the inner support ring portion 62 'over its length, ie designed between the inclined plane to the disk 200 abutting edges 64 "and 74".
  • the blades 48 are in turn connected by webs 84 with the inner support ring portion.
  • the webs are connected to the lying in the disk plane neutral fiber 88, which is not on the edge of the support ring portion but in the interior.
  • Column 86 are formed between edge and neutral fiber, so that the webs come to rest in the disk plane.
  • the use of the inner support ring portion is advantageous over a likewise conceivable use of the outer support ring portion, since complex, adapted to the use of configurations of the spacer ring omitted.
  • FIG. 11a Another embodiment show the Fig. 11 to 13 ,
  • the inner support ring sections 62 '"and 66'" of two part discs can be seen in the plan view.
  • At least the partial disk 62 "' has a bead 100, which is guided as far as the abutting edges 62'" and 74 '.
  • the bead runs according to FIG Fig. 11a not coaxial to the support ring. This is Fig. 11b illustrated by the radii.
  • the radius of the deepest point of the bead has at the abutting edge 64 '''a large radius 104 which is greater than the small radius 102 at the abutting edge 74'''. This choice of radii prevents the edges from sliding over each other. Radially inside and outside the bead lie flat portions 106 and 102, on which the abutting edges of the part discs are superimposed.
  • the bead can have different cross sections.
  • the bead 100 has a substantially triangular cross-section.
  • the bead 100 'in Fig. 12a has a rectangular, the bead 100 "in Fig. 12b a round cross section.
  • the beading can also be seen in a continuing education, shown in Fig. 13a and 13b , Tabs 110 and 112, which bring the beads 100 of the support ring portions 62 '' and 66 '' in engagement with each other when assembled.
  • Fig. 13 achieved in which the tabs are arranged on crossed sections of the bead, so that an effect analogous to Fig. 6a and b results.
  • Fig. 13b is the support ring portion 66 '"shown in dashed lines, the support ring portion 62'" with a solid line. This illustration illustrates the crossed position of the bead sections to each other.
  • Fig. 14 is an expression of this idea shown, in which the support ring portions 62 “" and 66 “” have beads 100 which are arranged at the abutting edges 64 "" and 68 “” radially offset from each other so that they do not overlap.
  • tabs 114 and 116 are arranged, which protrude respectively into the space created by the bead of the opposite support ring portion.
  • the bead may be provided in sections only in the region of the abutting edges. It is advantageous to let it run over the entire length of the support ring portion between the abutting edges, since as a further advantage, a stiffening of the support ring portion is achieved.
