Definitions

  • the invention relates to an inner-axis crankshaft-free rotary piston machine with two eccentrically mounted rotors, the circularly curved raceway of the bearing of the outer rotor enclosing the shaft of the inner rotor.
  • Rotary piston machines of the type mentioned are known, for example, from US-A-724 665, US-A-3 954 355 and GB-A-961 872.
  • the design principle of a machine of the type mentioned at the outset inevitably entails that the raceway of the two bearings of the outer rotor has a relatively large diameter, since it surrounds the shaft of the inner rotor arranged eccentrically to it, if both rotors are not only disadvantageously be stored on one side.
  • the bearings of the rotors of the known machines mentioned are designed as slide bearings, so that they have only a small dimension in the radial direction.
  • the relatively large diameter of the bearing of the outer rotor results in correspondingly high bearing speeds, so that the known machines are only suitable for relatively low rotational speeds and have relatively high friction losses.
  • the use of conventional roller bearings for the bearing of the outer rotor would lead to a structurally disadvantageous increase in the radial dimension of the bearing or to a further increase in the bearing race.
  • the speed of rotation of the machine would also be relatively limited, since the large diameter of the raceway would lead to a correspondingly high speed of rotation of the rolling bearing bodies.
  • the present invention is based on the object of avoiding the disadvantages of the known machines, so that they can be operated at significantly higher rotational speeds and thus can be used in small dimensions for new applications, e.g. as a loader or driver of an internal combustion engine.
  • the invention is based on the further object of being able to arrange the shaft of the inner rotor relative to the outer rotor with greater eccentricity and / or to be able to give it a larger diameter.
  • the shaft of the inner rotor can be arranged between such bearing devices so that it is located radially further out.
  • the shaft itself can form one of the bearing devices by rolling the bearing race on the circumference of the shaft or on a ring surrounding the shaft.
  • the bearing devices preferably consist of rollers that can be supported by ball bearings.
  • the bearing of the outer rotor is preferably arranged in the axial direction of the machine between its runners and a drive connection between the runners, the individual bearing devices being carried by a sealing body which is rigidly connected to a fixed outer machine housing and in the bearing raceway of the outer rotor enclosed space extends up to the side surface of the inner rotor and is sealed radially from the outer rotor. Because the sealing body thus provides a radial seal with respect to the outer rotor or the annular space formed by the usual hollow gear of the outer rotor is avoided, it is not necessary for the side face of the inner rotor to cover such a cavity in every movement position by a suitable size of the inner rotor and thus seals to the working area of the machine.
  • the arrangement of the drive connection between the two rotors in the axial direction, given by a pinion engaging in a ring gear, or the arrangement of the bearing in the axial direction between the drive connection and the inner rotor has the further advantage that the cavity of the outer rotor for the passage of the shaft of the Inner rotor can be made smaller in diameter than the diameter of the hollow gear of the outer rotor.
  • the shaft diameter of the inner rotor can advantageously be chosen larger by arranging the shaft between two bearing devices arranged next to one another in the circumferential direction.
  • this does not allow the shaft diameter to be increased at the point at which the pinion of the drive connection between the two runners is provided, because the diameter of the pinion is determined by the eccentricity between the two runners and the required transmission ratio.
  • the drive transmission between this pinion and the hollow gear of the outer rotor takes place via two intermediate gears or an intermediate annular gear with an internal and external teeth. It is understood that in this case the hollow gear of the external rotor is to be made larger in diameter.
  • the present invention can be advantageously used with all rotary piston machines of the type mentioned at the outset, since the inner-axis construction requires an outer rotor which has a relatively large bearing race in diameter, so that correspondingly high speeds occur in this race.
  • the storage devices in the form of rollers can also be used, e.g. individual magnetic bearings, individual air cushion bearings, etc.
  • the support rollers can also be used for the lateral guidance of the external rotor, i.e. they can also absorb forces acting on the outer rotor in the axial direction if they are provided with a wheel flange or a groove which interacts with a groove or a wheel flange of the raceway of the outer rotor.
  • the inner rotor 4 has a circular cross section and rotates in an eccentric movement about the main shaft 6 of the machine, which only rotates about its own axis.
  • the shaft 6 is supported by two roller bearings 9, 10 in sealing bodies 13, 14 which are rigidly connected to the side housing covers 11, 12.
  • a second bearing 15, 16 provided on the outer circumference of the sealing bodies 14, 13 serves to mount the outer rotor 18 about its central axis, which is thus fixed locally. Due to the large diameter of these bearings 15, 16 and the relatively small diameter of the rolling elements of these bearings, the latter are exposed to high rolling speeds and thus high loads, which should be avoided according to the present invention.
  • a seal 20, 21 between the side walls 26, 27 of the extension 18 facing the working space 22 of the machine and the part 19 of the sealing body 13, 14 protruding into it prevents the bearings 9, 10, 15, 16 and a drive transmission 23 between the Internal and external rotors can disadvantageously come into contact with the medium flowing through the machine. The throughflow takes place through the nozzles 7, 8 attached radially on the outside of the machine housing.
  • the outer rotor 18 enclosing the inner rotor 4 consists of two crescent-shaped peripheral parts 24, 25 lying opposite one another and two side parts 26, 27 enclosing them between one another , so that the inner rotor can execute a reciprocating movement in the working space 22 delimited by these surfaces.
  • This relatively straight-line movement of the inner rotor 4 relative to the outer rotor 18 despite the rotary movement of both rotors results from the kinematics of gimbals.
  • the inner rotor 4 which can also be referred to as a rotary piston, comes into meshing engagement with two gaps in the outer rotor so that it rotates at twice the speed of the outer rotor.
  • the gear ratio accordingly corresponds to 1: 2, so that the pitch circle of the pinion 34 of the drive transmission 23 between the inner and outer rotor has half the diameter of the pitch circle of the hollow gear 35.
  • FIGS. 5-7 show, however, that the ratio of 1: 2 can also be achieved in other ways.
  • the shaft for cooling the inner rotor 4 as shown in FIG Fig. 8 can be made hollow and / or for a greater axial length of the rotor receives a higher strength, can according to the schematic representations of FIGS.
  • FIG. 3 and 4 show an embodiment according to the invention in that the outer rotor 18 'is supported by three rollers 52, 53, 54 which are themselves mounted on the sealing body 14'. Two of the rollers (52, 53) are supported by a bearing pin 56 in the sealing body 14 ', while the third is supported on the shaft 6.
  • These rollers 52 to 54 made of hardened material roll on a bearing ring 58 made of hardened steel, which is inserted into a lateral hub part 60 of the outer rotor.
  • a lateral end face of the hollow gear 62 secures the axial position of this bearing ring 58.
  • the immediate arrangement of the bearing ring 58 and the bearing rollers 52 to 54 rolling thereon ensures a good lubrication by the lubricant supplied to the gear.
  • a ring 54 can also be firmly attached to the shaft if its diameter is equal to the pitch circle diameter of the pinion 34, so that at the speed ratio of 1: 2 a slip-free rolling on the radially inner tread of the Bearing ring 58 takes place.
  • a sealing ring 66 is provided which ensures the sealing of the part of the machine provided with lubricant together with the seal 20 on the sealing body 14'.
  • the rollers 52-54 can be provided with a web or wheel flange which is small in cross-section and which engages in a correspondingly shaped groove in the bearing ring 58, so that there is guidance against axial displacement between the shaft and the external rotor is.
