Definitions

  • the invention relates to a method for producing an inner-axis rotary piston machine according to the preamble of claim 1 and to a rotary piston machine produced by the method according to the invention.
  • Deviations from the ideal kinematic shape result in the production of the curvature of the engagement surfaces of the two runners and in the mutual assignment of the engagement parts of the outer rotor in the tangential and radial directions and in the assembly of the runners relative to one another and relative to the enclosing housing. Since the different deviations at certain sealing areas can add up, wide sealing gaps must be provided that take into account the added maximum manufacturing and assembly tolerances in order to prevent contact at the sealing points. The consequently wide sealing gaps of rotary lobe machines, which have been manufactured in the usual way, cause poor efficiency of the machine due to sealing losses.
  • the rotary lobe machines that have become known from the specialist literature are not suitable for series production due to the complex and inaccurate manufacturing processes langt or they were only intended for the throughput of liquid media and operated at suitable relatively low speeds.
  • the US-PS 1 753 476 shows an embodiment of a known rotary piston machine, in which geometrically simple, but kinematically imprecise engagement surfaces with consequently wide sealing gaps have been accepted to simplify the manufacture, so that it is only suitable for the conveyance of relatively viscous media .
  • Your external rotor is made in one piece, its engagement parts being held on one side only on a rotor side part and consequently can only be loaded by small centrifugal forces, or can only have a short axial extension.
  • the invention has for its object to find a method by which a rotary engine of the type mentioned in the preamble more precisely, i.e. with narrower dimensioned sealing gaps, can be manufactured and is therefore suitable for gas production with good efficiency and high rotational speeds.
  • This object is achieved on the basis of the features of patent claim 1.
  • Advantageous embodiments of the method and a rotary piston machine produced by the method are the subject of the dependent patent claims.
  • the machine shown has a speed ratio between the outer rotor 2 and the inner rotor 3 of 2: 3, so that three engagement parts 2a, 2b, 2c are provided on the outer rotor and two engagement parts 3a, 3b on the inner rotor 3.
  • the machine housing 1 has an inlet channel 4 and an outlet channel 5 on its circumference, which are sealed off from one another by the passage close to the sealing gap on the outer peripheral surface 7 of the engagement parts 2a, 2b, 2c along the inner surface 8 of the housing.
  • the runners 2, 3 are supported by roller bearings 10, 11 which are supported on side plates 12, 13 of the housing 1. Due to the distance a between the geometrical axes 14, 15, the inner roller bearing 11 of the inner rotor 3 has a radially offset position within the surrounding outer roller bearing 10 of the outer rotor 2.
  • the outer rotor 2 17, 18 hubs are on the side parts thereof 19,20 formed, which include the roller bearings 10.
  • part of one of these hubs 20 forms a hollow gear 21, with which a spur gear 22 meshes, which is placed on the shaft 23 of the inner rotor 3.
  • the side parts 17, 18 of the external rotor 2 connect its three engagement parts 2a, 2b, 2c to one another and, together with a sealing body 25, 26 firmly connected to the housing side plates 12, 13, seal the working spaces 9 of the machine in the axial direction.
  • these side parts 17, 18 of the outer rotor 2 have the form of circular rings, each of which has a radial seal 27, 28 radially outside and radially inside.
  • the method according to the invention shows a way in which a precise positioning of the engaging parts 2a, 2b, 2c of the outer rotor 2 with respect to the minimum sealing gap widths is possible relative to the side parts 17, 18 of the outer rotor 2, which determine the position relative to the machine housing 1 via their mounting .
  • the engagement parts 2a, 2b, 2c or 2a ', 2b', 2c ' are positioned relative to the side parts 17, 18 of the external rotor by means of mounting bodies 35 - which engage between the engagement parts. 37 and the abutment of their outer peripheral surfaces 7 on outer circular arc pieces 38-40.
  • the design of these assembly bodies 35-37 and the assembly circle pieces 38-40 as precision parts results in very precise positioning, without significant dimensional deviations between a large number of mass-produced external rotors. According to the exemplary embodiment in FIG.
  • one of the mounting bodies 36 " can be adjusted in width by means of an inserted sliding wedge 42, so that after insertion between the engagement parts 2a" and 2c "the corner areas thereof can be covered with lateral extensions 43,44.
  • all of the mounting bodies 35 "-37” can also be designed to vary in width.
  • the mounting bodies 35'-37 'of the exemplary embodiment in FIG. 5 are provided with cutouts 48 on their end faces, so that lateral extensions 49, 50 are present which, despite the inner rotor 3 already inserted, make the mounting contact on a substantial area of the inner surfaces 30, 31 of the Engaging parts 2a ', 2b', 2c 'enable by engaging the engaging parts 3a, 3b of the inner rotor 3 between them.
  • By mounting the engaging parts 2a ', 2b', 2c 'on the screen Tent parts 17, 18 when the inner rotor 3 is already inserted, which is fixed in position relative to the side parts 17, 18 of the outer rotor 2 (FIG.
  • the engagement parts 2a ', 2b', 2c 'can also can be mounted exactly relative to the inner rotor 3. It is also possible to carry out the assembly or alignment of the engagement parts in the case of already mounted roller bearings 10, 11 and attached housing side plates 12, 13, the engagement parts 2 a ', 2b', 2c 'being fastened, for example, by welds which are made on the outer circumference of the outer rotor 2 be provided.
  • the fixed connection between the engaging parts 2a, 2b, 2c and the side parts 17, 18 and 17 ', 18' can be made by conventional connecting means, such as adhesives, weld seams, screws 58, 59; 60, 61, 62 and the like.
