Definitions

  • the invention relates to a principle and system for sealing rotary piston against the surrounding housing wall of rotary compression and -Expansionsmaschinen.
  • Wankel an engine type the only two relatively moving, the work space enclosing components comprising: a housing with a trochoidenförmigen career and also derived from a Trochoide rotary piston as the inner envelope body of the housing track.
  • a housing with a trochoidenförmigen career and also derived from a Trochoide rotary piston as the inner envelope body of the housing track.
  • On this piston can be arranged sealing strips that meet the condition of the unchanged geometric shape.
  • Wankel engine has become known as Wankel engine. Despite the merits and successful development of this engine type, some technical goals could not be achieved. This concerns the geometric volume change with the used trochoid, which does not allow the implementation of a conventional diesel process. This also applies, less drastic, the lubrication of the sealing strips and related to the heat dissipation from the piston to the housing wall.
  • the object is to provide a sealing system for rotary piston machines, which applies the principle of the same geometric shape of the sealing line according to F. Wankel so that other types of rotary piston machines for expansion and compression processes in higher temperature ranges as well can be realized with improved volume change, lubrication and heat dissipation characteristics.
  • the rotor consists of two or more parallel rotor disc segments, of which the outer, facing the frontal housing walls discs are pressed by spring and / or gas forces on the housing wall, that they there abut sealingly with its surface and a flow around is not possible and in that the sealing of the resulting between the rotor segment discs joints are sealed by sealing strips within the joints and connect these sealing strips to the sealing strips, which rest against the housing track so resiliently that a system of continuous planar sealing lines results, which no longer has interruptions.
  • the inventive solution further consists in that the sealing strips are formed by packages of movable mold plates, which form labyrinth seals with itself and together with the rotor disk segments and in that the disk packs by means of spring and / or media forces to the geometric Variations of the rotary piston machine, which occur in the movement or by pressures and temperatures can adapt.
  • the inventive solution consists in the fact that the sealing strips, which bear against the circumference of the housing track, consist of mold blades that overlap each other so that they form sealing edges that extend flexible in the rotor movement in the corner regions of the housing and seal them and in that these form blades by spring forces the radial and axial changes in the housing to adjust.
  • the inventive solution consists in the fact that the form of slats have skewed edges, so that wedge-shaped pressure elements can act by spring force on the beveled edges, that the slats can be moved in both directions of a plane against each other and thus form the packets of mold blades sealing elements, which can adapt to the room in which they are arranged in two directions.
  • the disk segments, of which the rotor is composed, on the mutually facing sides on radial grooves are fitted into the packets of mold blades, so that the joints between the disk segments are sealed by flexible labyrinth seals.
  • the disk segments on the mutually facing sides around the rotor axis around annular grooves in which either a closed ring can be used and seals the rotor to the axis or a disc segment has an annular recess which fits into the opposite annular groove of the counter-disc and the Rotor seals towards axis.
  • rotor disks which form the piston, on their outer surfaces recesses between the piston tips have such that at these recesses media forces can attack, which are directed against the forces acting in the joints media forces and so reduce the resulting pressure forces against the housing wall to the extent that ensures the tightness, but minimizes the frictional forces.
  • the inventive solution also includes that the disc segments are designed so that they form a labyrinth seal even as a form of lamella in conjunction with other form of slats.
  • FIG. 1 Principle of the adaptable sealing line on the vane-cell rotor
  • Figure 3a split Wankel rotor 28, 29 rotor segment
  • FIG. 3c. 3d sealing group
  • Figure 1 The principle of the seal is described with reference to Figure 1.
  • the rotor of the machine is separated into the two segment discs 1 and 2, which are pressed with their outer surfaces 6 and 8 by spring / media forces on the front sides of the housing and thus seal the rotor against the housing.
  • the gap 11 between the segment discs is closed inwardly towards the rotor shaft by a peripheral cover 10.
  • the guide grooves 5 With the cover 10, the guide grooves 5 are connected, in which wing parts 3, 4 sit, which form a wing of the vane cell rotor.
  • the wings 3, 4 are formed by form of slats, which can adapt to the geometric changes.
  • Figure 2a The rotor of the vane cell rotor consists of the disk segments 12 and 13, which are pressed apart by springs 14 and thus sealingly abut against the end faces of the housing.
  • the springs are located in the (non-continuous) holes 15 in both segment discs.
  • the segmental disc 12 engages with the hub 17 in the receptacle 16 of the segment disc 13 and closes the parting line 19, corresponding to the cover 10 according to Figure 1.
  • the slots 18 in the segment discs 12 and 13 speak the guide grooves 5 according to Figure 1.
  • Figure 2b In the slots 18 of the rotor are the wing cassettes 20, which adapt due to their internal spring forces in the radial direction of the housing track and in the axial direction of the front sides of the housing and at the same time in the corners between the two treads extend the housing and seal it.
  • the two identical half-wings 21 and 22 which are stacked so that they can be moved against each other and thus come to the front sides of the housing as a seal to the plant. In this position they form with the disc segments 12 and 13 continuous sealing surfaces against the passage of the medium.
  • the pressure force of the half-wings 21 and 22 for this system is achieved by the inner beveled edges 23 and the pressure wedge 24 resting on the compression spring 25.
  • the pressure wedge 24 is located in the inner space formed by the half-wings 21 and 22.
  • the compression spring 25 is supported against the bottom of the cassette shell 27.
  • the radial sealing movement of the half-wings 21 and 22 in the rotation of the rotor is additionally achieved by the springs 26.
  • Figure 2c shows the nested disk segments 12 and 13 with a wing cassette 20 in the slot 18 in the rotor.
  • FIG. 1 Another embodiment of the principle of sealing a rotary piston show the pictures 3a, 3b, 3c and 3d for the rotor of a Wankelmaschine.
  • FIG. 3a The rotor for a Wankelmaschine consists of the two identical rotor segments 28 and 29. In the rotor segments are three radial grooves 30 which extend from the central bore 34 in three tips of the rotor. The radial grooves 30 merge into the axial rotor slots 31 in the rotor tips. The grooves 30 and 31 serve to receive the flexible sealing elements. In the central bore 34 of the ring 35 is used.
  • Figure 3b The ring 35 is inserted into the bore 34 so that the rectangular pin 36 located on it sit in the grooves 30 of the rotor segments 28 and 29.
  • the ring 35 serves to seal the gap between the rotor segments 28 and 29 against the rotor axis.
  • the pins 36 also seal the joint and are at the same time abutment for the sealing cassettes 39.
  • Figure 3c The identical shape blades 37 are superimposed so that they show with their side sealing strips to opposite sides. It is thus formed a common sealing strip with an overlapping joint.
  • the compression spring 40 are supported against the pin 36.
  • the mold blades 37 cover the pins 36 so that the sealing unit formed therewith can be inserted into the rotor grooves 30 and 31
  • FIG. 3d The existing of the mold blades 37, the pressure wedge 39 and the compression spring 40 sealing unit is placed on the pin 36 of the sealing ring 35.
  • the sealing ring 35 with the sealing units sits in the grooves 30, 31 of the rotor segments 28, 29. These components form the sealing system of the rotor.
  • the compression springs 41 By the compression springs 41, the rotor segments 28, 29 pressed against the end faces of the housing. This spring force is necessary for the concerns of the rotor segments during the starting process. When the machine is running, the media pressure takes over this pressure function. To reduce the friction on the frontal surfaces, the rotor segments recesses 33, which cause a pressure relief of the rotor segments.
  • FIG 4a The rotor of a Wankelmaschine consists of a central rotor segment 42 and the two side rings 43. Both side rings 43 engage with the recesses 46 and the pin 47 in the lateral annular grooves 44 and the radial grooves 45 of the piston center part 42 a. In the piston middle part are the through holes 49 in which the compression springs 50 sit, which are supported against the recesses 46 on the side rings 43 and press them against the side walls of the machine and seal the rotor against a circumferential flow.
  • the side rings 43 have no function for transmitting the torque.
  • the mold blade 51 has its full thickness in the area 51a. In the region 51b, the mold blade has only half the thickness. Two identical mold blades are mutually overlapped so that they form a package which is inserted into the transverse grooves 48 and the radial grooves 45 of the rotor, that the two sides 51a are directed to the side surfaces of the rotor and the pins 47 of the side rings 43rd extend into the slots 5 Ie. Pin 47 and slots 5 Ie form with this overlap on the side surfaces of the rotor a closed seal.
  • FIG. 4b Two mold blades 51 form a space in the covers 51c
  • Figure 4c shows the fully assembled with the form of fins 51 plate packs and equipped with the side rings 43 rotor.
  • FIG. 5a The rotor of a rotary piston of the machine consists of the rotor segments 54 and 55, which have a force acting against the central shaft seal by the annular recess 57 is fitted into the annular groove 56.
  • the fixedly connected to the rotor segments 54 and 55 made of the same material or another suitable firmly inserted material sealing lips 58 inserted into one another.
  • the sealing lips 58 milling mills 59, which allow the mutual nesting.
  • Figure 5b In Figure 5b, the rotor segments 54 and 55 are facing each other in the same axis alignment so that the recess 57 is directed to the annular groove 56.
  • the sealing lips 58 fit with their milled grooves 59 into one another such that in the radial and axial direction of the rotor a dynamic tightness acting in the movement sequence of the rotor is achieved.
  • the sealing of the rotor segments 54 and 55 against the end faces of the housing is achieved by the spring force of the springs 62.
  • the recesses 63 on the outer sides of the piston segments 54 and 55 cause the media forces which act in the parting lines of the rotor segments 54 and 55 as acting after the end faces of the rotor frictional forces are largely compensated by externally acting media forces.
