Definitions

  • the invention relates to a two-disc rotary piston machine with stroke engagement between rotors eccentrically rotatably mounted in a stationary housing and a power part penetrating each rotor radially as well as with slip engagement between the housing shell and the power parts, which are guided radially to the housing shell within the rotor, such that that their ends are held at two diametrically opposite points with the housing jacket forming two working chambers in a sealing slide system.
  • a two-disc rotary piston machine of the aforementioned type is already from the DD-PS 46 761 known.
  • a recess is provided in the interior of each rotor, in which a closed eyelet is accommodated, from each of which an arm of the power section extends on opposite sides.
  • the eyelet received in each rotor interior surrounds a fixed guide pin arranged in a side part, so that the inner surface of the eyelet, which serves as a guideway, can rotate smoothly around the guide pin.
  • a balance weight is provided between the two rotors.
  • the known rotary piston machine can only be operated with very large mechanical losses, because the bearing of the power parts has many friction surfaces and the balance weight represents a dead mass that must be set in rotation to reduce performance.
  • a further disadvantage of the known machine is that the guide track designed as a closed oval for the guide pin requires a divided rotor, since otherwise the parts cannot be assembled.
  • the invention is based on the object of designing a rotary piston machine of the type mentioned above in such a way that the mechanical losses are kept small with a simple construction of the machine and weights for mass balancing are unnecessary.
  • the machine has on both sides of the rotors 1, 21 side housings 5, 25 and housing shells 3, 23 arranged between the side housings.
  • the rotors 1, 21 are screwed to an output body 50 and rotate about a common axis.
  • the housing parts are centered by dowel pins and are by tie rods 18, 38 on one side are screwed tightly into an inlet housing 49, and held together on the side housing 5, 25 by nuts.
  • Bearing flanges 4, 24 are screwed to the end faces opposite the rotors, which are rotatably connected by bearings 6, 26 to journals 7, 27.
  • Each of the rotors 1, 21 has a through bore transverse to its axis of rotation, in each of which a power element 2, 22 is received so as to be displaceable in the longitudinal direction.
  • Each power section 2, 22 has, in the middle of its longitudinal dimension, a guide groove 31 running transversely to the longitudinal section of the power section, the width and depth of which are adapted to a guide pin 8, 28 such that the power parts are securely guided by the guide pin.
  • the axes of these guide pins are offset by 180 ° with respect to the rotor axis. The fact that the guide pins are rotated by 180 ° relative to one another ensures mass balancing without the need for additional balancing weights.
  • Each guide pin 8, 28 is non-rotatably and eccentrically connected to the associated bearing pin 7, 27.
  • Each journal 7.27 extends into an axial recess in a rotor flank.
  • the axes of the trunnions are arranged eccentrically to the axis of the inner radius of the housing shell, so that the rotors are mounted eccentrically within the housing.
  • sealing elements 41, 42 and 43 are pressed by means of springs against the rotor bore or the lateral housing race 46, the middle housing race 47 and the inlet-side housing race 48.
  • inlet channel 11 for each chamber in each rotor and an outlet channel 12 on the bearing flange side.
  • the fresh gas enters the chamber through an inlet regulator 53, an inlet housing 49 and the inlet channel 11.
  • the exhaust gas flows out of the chamber through the outlet channel 12 and out of the housing 5, 25 via an outlet ring channel 13, 33.
  • a rolling ring 10, 30 is provided on the bearing journal 7, 27, on each of which an intermediate gear wheel 20, 40 rolls, each of which drives a control shaft 9, 29.
  • This control shaft actuates the control elements known per se, such as valves, slides, etc.
  • oil is supplied through oil inlet bores 14, 34 and, with the aid of bores 32, is supplied to an oil ring channel 19, 39, from where it passes through oil outlet bores 15, 35 emerges from the housing sections 5, 25.
  • An oil sealing ring 45 is provided on each of the bearing flanges 4, 24, which prevents oil passage from the engine compartment into the outlet ring channels 13, 33.
  • the torque generated in the chambers is output from the drive body 50 with the aid of a ring gear 51 to an intermediate gear 55 which is mounted in an intermediate gear bearing 54 which is screwed to the inlet housing 49.
  • Cooling water channels 16, 17, 36, 37 and 52 are provided for cooling, although air cooling is also possible instead.
