Definitions

  • the invention relates to a device for conveying, preferably under pressure, of liquid media or for conveying and / or compressing gaseous or liquid media, with a housing with a pressure and a suction connection, in which housing an eccentrically rotatably mounted to the housing Rotor is arranged, in which at least one slider is held, which is slidable in the radial direction, which runs along the inner wall of the housing in a sealing manner and which is guided along guideways arranged on the inside of a shoulder, on which two rolling elements connected to the slider roll, wherein a rolling element rolls on each guideway, and wherein the line of contact of the rotor with the inner wall of the housing lies between the suction and the pressure connection.
  • a device of this type namely a pump, has been e.g. known from U.S. Patent 3,001,482.
  • slides are provided with rollers which are guided in a groove-shaped guide with considerable play in order to avoid jamming of the rollers.
  • DE-C 443 963 discloses an engine with revolving radial pistons guided by rollers and curves.
  • rollers and mechanisms divide the work area, these guideways do not guarantee tightness in a larger area around the inlet and outlet.
  • the radial piston is driven by rotors, which results in friction losses and shear forces between the rotor and the piston.
  • FR-A 1091637 in turn shows a rotary machine without guiding the movable slide at the rotor-housing contact point. This leads to severe wear.
  • the seal is achieved in the lower speed range by spring force, in the areas above it by additional centrifugal force. Due to the design of the contact surfaces of the housing, the rotor moves erratically.
  • the aim of the invention is to avoid these disadvantages and to propose a device of the type mentioned at the outset in which play-free guidance of the slides is ensured without the risk of the slides jamming.
  • this is achieved in that the slide or slides is driven by the drive shaft of the rotor and by the rotor cylinder, that the projections of the two guideways cross each other at two diametrical points in a plane perpendicular to the drive shaft of the rotor, and that the projections of the two Guideways represent geometric curves, which ensure exact guiding of the slider on the inner wall of the housing cylinder for any position of the rotating slider, whereby the wear on the contact points is reduced to a minimum over the entire speed range.
  • the guideways are essentially slightly deviating from the circular shape, the extent of the deviation being determined by the eccentricity of the drive shaft (and therefore also of the rotor and the slide) with respect to the housing cylinder.
  • Another object of the invention is to propose a work or power machine.
  • the housing have at least two separate chambers, in each of which a rotor is arranged with a slider, the rotors being connected to one another in a rotationally fixed manner, and the sliders being controlled by two guideways arranged in a manner known per se on the inside of the flat side walls of the housing cylinder such that the projections of the two guideways into one Plane perpendicular to the drive shaft de s runner each other at two diametrically cross opposite points, and that the two guideways represent geometric curves, which ensure exact and play-free guidance of the slider on the inner wall of
  • the proposed measures ensure reliable guidance of the slide. By guiding the slide with two rolling bodies rolling on different guideways, exact and practically backlash-free guidance is ensured, and the risk of jamming is also avoided. There is also only minimal wear, since the rolling elements roll on free tracks.
  • the one guideway supports the slide against the centrifugal forces that occur during rotation, while the other guideway takes care of the tightness of the contact point between the slide and the housing cylinder.
  • This shape of the guideways ensures a very smooth and jerk-free rotary movement with an eccentric arrangement of the slide.
  • the drive shaft 3 is mounted eccentrically in the housing 5, or on bearings held on the plates thereof.
  • the housing 5 has an inlet 5a and an outlet connection 5b for the liquid medium to be preferably conveyed under pressure or the gaseous medium to be conveyed and / or compressed. Operating modes of e.g. as a gas or liquid pump, compressor or the like are thus possible.
  • This end shield is designed as a control ring 1 and has guide tracks 1a, 1b arranged on the inside of a tubular extension in two different planes perpendicular to the drive shaft 3.
  • a hollow rotor 4 is arranged in the housing, which is arranged centrally on the drive shaft 3 and is driven by the latter.
  • the annular wall of the hollow rotor 4 is provided with a slot 7, which is penetrated by the slide 2.
  • the slider 2 has an elongated slot 9, which is penetrated by the drive shaft 3, which has flats 10 in the area of the slider 2, which can slide along the walls of the elongated slot 9 of the slider 2 and intervene with little play between them.
  • the desired one Distance of the end face 11 of the slide from the inner wall 12 of the housing can be maintained, by means of which the wear of the slide can be kept correspondingly low.
  • the course of the two guideways 1a, 1b depends on the shape of the inner wall 12 of the housing 5 and the eccentricity of the drive shaft in relation to the housing 5, and depending on the size of the hollow rotor 4, the size of which determines the measure of the delivery rate or the output of the pump.
  • the housing 105 of the engine according to FIGS. 3 to 5 has an inlet and an outlet connection 109, 110 for the mixture to be compressed.
  • the bearing plates 151, 152, 153, 154 are provided with control rings 101 and have guide tracks 101a, 101b arranged on the inside of a tubular extension in two different planes perpendicular to the drive shaft 103.
  • Two chambers 160, 161 are arranged in the housing 105, in each of which a hollow rotor 104 is arranged, which is arranged centrally on the drive shaft 103 and is driven by the latter.
  • the annular wall of each hollow rotor 104 is provided with a slot 155 through which the slide 102 passes.
  • the slider 102 has an elongated slot, which is penetrated by the drive shaft 103, which has flats in the area of the slider 102, which can slide along the walls of the elongated slot of the slider 102 and engage between them with only slight play.
  • Rollers 116 are also held on each slide 102, two of which each roll on a different guideway 101a, 101b.
  • the rollers 116 which roll on the two guide tracks 101a, 101b, the projections of which cross each other in two diametrically opposite points, the desired distance of the end face of the slide from the inner wall of the housing 105 can be maintained, through which the wear of the slide 102 can be kept correspondingly low.
  • the course of the two guideways 101a, 101b depends on the shape of the inner wall of the housing 105 and the eccentricity of the drive shaft in relation to the housing 105, and on the size of the hollow rotor 104, the size of which determines the measure of the performance of the machine .
  • the diametrical spacing of the two guideways 101a, 101b from one another always remains the same, which ensures exact guiding of the slides 102, by absorbing the centrifugal forces which occur during operation, which would lead to the slider being pressed against the inner wall of the housing, which correspondingly high wear would have occurred.
  • the drive shaft 103 is divided by a clutch 115, the coupling halves of which are connected in a rotationally fixed manner to the two parts of the drive shaft 103 and are provided with a toothing which is in mutual engagement.
  • the chamber 160 has an outlet 162 next to the inlet 109 of the housing 105, which outlet is connected to the second chamber 161 via a connecting line 107.
  • a hollow cylinder 106 is arranged between the connecting line 107 and the inlet 171 of the second chamber 161, the cylindrical wall of which is penetrated by two slots 172, 173.
  • this hollow cylinder 106 can be rotated by means of a cam 111 and a linkage 112.
  • the slider 102 arranged in the chamber 161 is only partially indicated for the sake of clarity, with the omission of the rolling elements 116; however, the arrangement and design correspond to that of the slider arranged in the chamber 160, cf. Fig. 5.
  • the cam controller 111, 112 reverses the hollow cylinder 106 and the slot 173 coincides brought with the inlet 171 so that the pressurized mixture can flow.
  • the rotor 104 arranged in the chamber 182 is in a position in which its recess 117 arranged in the lateral surface is opposite the inlet 171, which opens essentially tangentially into the chamber 182.
  • a spark plug 108 is arranged next to the inlet 171 and ignites the mixture.
  • the associated expansion of the fuel gas drives the rotor 104 in the direction of the arrow 175, the gas in the space 182 being expelled via the outlet 110 of the housing 105.
  • the rotor 104 of the chamber 160 is driven via the drive shafts and the clutch 115, which in connection with the slide 102 sucks and compresses mixture.
  • the compression of the mixture can be increased or decreased.
  • the compression can also be increased so far that the mixture ignites by itself, so that under certain circumstances. the spark plug 108 can be dispensed with.
  • FIG. 6 shows the creation of the geometric shapes of the guideways 1a, 101a and 1b for the exemplary embodiment according to FIG. 1 and that according to FIG. 2.
  • the shape of the guideway 1b, 101b, of which about a half is shown, must be determined in accordance with the conditions which should prevail at the point of contact 52 between slide 2, 102 and housing 5, 105.
  • Both the center path 1b ', 101b' of the rollers 2b, 116 and the guideway 1b, 101b will generally differ only slightly or not at all from a circular path around the housing center 51.
  • a deviation from the circular path can e.g. to compensate for different centrifugal forces which occur due to variable slide positions and would necessarily result in different deformations on the supporting parts (rollers 2b, 116) and thus a grinding of the slide 2, 102 at the contact point 51.
  • the second guideway 1a, 101a which is to ensure a play-free slide movement, is due to the guideway 1b, 101b or its center path 1b, 101b and the constant center distance of the rollers 2a and 2b or 116 or the eccentricity e is defined as the distance between the shaft center 31 and the housing center 51.
  • the center path 1a 'of the rollers 2a can be understood starting from the center path 1b', as the set of all points which have a diametrically opposed constant distance with respect to the shaft center 31.
  • the guide track 1a, 101a of the only about half that is shown in FIG. 6, which corresponds to the half of the guide track 1b, 101b that is also shown, is then obtained as an equidistant with the distance corresponding to the roller body radius r to the center track 1a ', 101a ′.
