Definitions

  • Such wobble drives are particularly suitable for devices such as rotary piston displacement machines.
  • Swash drives of the type mentioned are known, for example from DE-C-2 603 462 and US-A-3 560 119.
  • These devices are so-called displacement machines for compressible media. They consist, on the one hand, of a conveying space which is delimited by spiral-like circumferential walls which extend perpendicularly from a side wall and which leads from an inlet lying outside the spiral to an outlet lying inside the spiral. On the other hand, they have a likewise spiral-shaped displacement body protruding into this conveying space. This is mounted in relation to the conveying space in order to execute a circular, rotation-free movement. Its center is offset eccentrically from the center of the peripheral walls so that the displacer always touches both the outer and the inner peripheral wall of the delivery chamber on at least one progressive sealing line.
  • the wobble drive is in each case the means for converting the rotating movement of the drive machine into the translatory movement of the displacer. Its radial displacement is limited by the contact of the spiral ribs with the walls of the delivery chambers. The limit theoretically corresponds to a circle, in this case the translation circle.
  • the drive solution in DE-C-2 603 462 provides an eccentric body which is seated in a rotationally fixed manner with a counterweight and on which a drive disk is mounted by means of a ball bearing.
  • This is equipped with four evenly distributed ball joint pans, in each of which the ball end of a wobble rod sits. The balls only have line contact in their associated pan.
  • the wobble rods When the drive shaft rotates, the rotor body is excited by the wobble rods to perform a circular but not rotating movement.
  • the wobble rods also have to ensure the anti-rotation device in this solution.
  • the drive-side pin of the wobble rod is rotatably and pivotably mounted in an eccentric position by means of a self-aligning ball bearing.
  • the second and third spherical sections are each provided with profile rings, e.g. Provide teeth, which in correspondingly profiled counterparts in the displacer or. intervene in the fixed housing part and are pivotally mounted therein.
  • the wobble shaft is axially secured via a lock washer located in the fixed housing part.
  • the invention is therefore based on the object of designing a wobble drive of the type mentioned in such a way that play-free cooperation of the two components is made possible even with increasing material removal as a result of wear.
  • the object is achieved in that the bearing bushes for the second and third spherical sections are hemispherical joint sockets which are arranged in mirror image in the two components, spring means ensuring that the spherical sections abut in the joint sockets.
  • the advantage of the invention can be seen in the fact that the new configuration creates a self-adjusting and almost maintenance-free drive for the orbiting component during operation.
  • the fixed component is designated with left housing half 1 and the rotating component with displacer 3.
  • the pump according to FIGS. 1 and 2 essentially consists of two housing halves 1, 2, which are connected to one another in a suitable manner, and the displacer 3 located therein.
  • An annular delivery chamber 4 is incorporated into the left housing half 1. It is divided by means of a web 5 which extends over the entire depth of the chamber. Both sides of the web are in the rear wall of the housing half 1, the inlet 6 and the outlet 7 for the working medium to be conveyed.
  • the likewise annular rib 8 of the displacer 3 engages in this delivery chamber.
  • the ring is slotted at the point opposite the web 5.
  • the displacer performs an orbital movement during operation.
  • the ring piston constantly touches both the inner and the outer peripheral wall of the delivery chamber. Due to its change in position, on the one hand, working fluid is sucked into the chamber 4 via the inlet 6 and, on the other hand, it is conveyed out of the machine via the outlet 7.
  • a cross-disk coupling is provided for the rotation-free guidance of the displacer 3. It consists essentially of an intermediate ring 9, which is provided with strips 10 on its two plan sides. The strips 10 facing the displacer 3 engage in appropriately configured, vertically running grooves 11 in the displacer 3. Those strips which face the fixed right housing half 2 must be arranged perpendicular to the former strips, in the present case thus horizontally and therefore not visible in the longitudinal section according to FIG. 1. They also slide in appropriately configured grooves that are machined horizontally in the front of the housing half 2
  • a drive by means of a wobble rod 12 is provided for the orbital rotation of the displacer 3.
  • a crank mechanism 13, not shown, is equipped on the crank side with an articulated socket 14, in which the wobble rod 12 is rotatably and pivotably seated with a first ball section 15. It is understood that the invention is not limited to this drive variant.
  • the only decisive factor is a construction in which the wobble rod does not perform a rotary movement but a wobble movement, the axis of movement being located on a cone jacket.
  • the wobble rod 12 has a second ball section 16. Coaxial with the main axis of the crank mechanism 13, this second spherical section is rotatably supported in the left fixed housing part 1 and is capable of tumbling.
  • the wobble rod 12 is provided with a third ball section, the ball radius of which advantageously corresponds to that of the second ball section.
  • This third spherical section is rotatably supported in the hub of the displacer 3 and is capable of tumbling.
  • bearing points are therefore designed as hemispherical joint sockets 18, 19. Hemispherical because, on the one hand, this reduces the required individual parts to a minimum, and on the other hand, assembly is very easy.
  • FIG. 3 A first solution to this is shown in FIG. 3.
  • the second ball section 16 ' is provided with a central bore and loosely attached to the wobble rod 12', so that it is displaceable on the wobble rod.
  • the opposing surfaces of the ball sections 16 'and 17' are flattened and each form a stop for a compression spring 20 '. In the assembled state, this spring 20 'pushes the ball sections apart.
  • the socket 18' in the fixed component 1 with a recess 21 To accommodate the wobble rod 12 'on the occasion of a shift of the Ball section 16 'is the socket 18' in the fixed component 1 with a recess 21.
  • the solution shown in Figure 4 is based on a sliding block 22, which is axially displaceable in the left housing part 1.
  • the joint socket 18 is incorporated in the sliding block.
  • the ball section 16 lies in this. So that the spherical section has a spherical support defined at all times, the base of the pan is also provided with a recess 21 here, so that the head end of the spherical section in no case has ground contact.
  • the axial force is applied via the coil spring 20, which acts on the sliding block 22 from the housing part 1.
  • the angle of the movement axis located on a conical surface also changes. This also applies to the distance between the ball sections 16 and. 17 and 15.
  • Eccentricity e (Fig. 4) must always be maintained.
  • the plane of the second spherical section is decisive for the translation circle and is therefore the reference plane. Therefore, the first ball section 15 must also be designed to be displaceable. Namely, it must be displaceable on the one hand in the longitudinal direction of the wobble rod, as is indicated in FIG. 4; secondly, it must also be displaceable in the direction perpendicular to the plane of the drawing because of the possible change in angle mentioned.
  • This first spherical section 15 is therefore preferably also embedded in a bearing bush designed as a joint socket 14.
  • This joint socket 14, which is shown only schematically in the drawing, is in turn provided with a sliding surface 23 which can be displaced on all sides on a corresponding counter surface of the crank mechanism 13.
  • the sliding surface 23 and counter surface are in one plane parallel to the axis of the crank mechanism.
