Definitions

  • the invention relates to a pressure medium cylinder with a longitudinally slotted cylinder tube which is closed at the end, in which a sealed piston is guided so as to be longitudinally displaceable and the longitudinal slot of which is sealed on both sides of the piston by an internal flexible cover band, which in the area of the piston and one which projects outwards through the longitudinal slot, with which Piston directly connected to the power transmission element is guided, the power transmission element being guided longitudinally via a parallel guide rigidly connected to the cylinder barrel and having at least two guide tracks lying outside the cylinder barrel.
  • the actuating force resulting from the pressure medium acting on the piston is transmitted directly through the longitudinal slot of the cylinder tube through the force transmission element to the driven device, whereby piston rods are omitted.
  • the longitudinal slot necessarily means a certain weakening of the cylinder tube, so that precautions must be taken in the event of higher loads in order to prevent undesirable expansion of the longitudinal slot. If the longitudinal slot widens, the sealing tape may function under certain circumstances no longer fulfill properly, with which leaks or even the so-called band explosion associated with a considerable risk of accident can occur. In addition, excessive side forces must not be exerted on the force transmission member by the driven device, because these forces must also be absorbed by the slotted cylinder tube.
  • the sealing strip Since the sealing strip must remain flexible in spite of its U-shaped cross-sectional shape, it can only absorb transverse forces acting on its flanges to a relatively small extent, which also limits its effectiveness in terms of keeping the longitudinal slot together. Attempts have also already been made (DE-PS 804 632) to remedy the weakening of the cylinder tube resulting from the longitudinal slot in that each longitudinal edge of the slot is delimited by an outwardly projecting longitudinal flange and the two longitudinal flanges by an attached, cross-sectionally C-shaped Brackets are held together.
  • the clip causes quite unfavorable sealing conditions with an external sealing tape and a complicated, with one part penetrating under the clip, force transmission element that only can be coupled laterally next to the longitudinal slot to the device driven by it, so that a moment is exerted on the power transmission element when driving, which is undesirable.
  • the object of the invention is therefore to provide a pressure medium cylinder with a longitudinally slotted cylinder tube which, with a simple structure, is characterized by a high strength of the cylinder tube against widening in the region of the longitudinal slot and which can also be used for applications in which the drive stroke is transverse to the longitudinal axis of the cylinder act directed forces on the power transmission element or it is exposed to the action of moments acting on it.
  • the pressure medium cylinder mentioned at the outset is characterized in that on both sides of the longitudinal slot Two parallel guideways are arranged directly on the outside of the cylinder tube in the area between the outer edge of the longitudinal slot and the plane of symmetry containing the piston axis, and in that the force transmission element has a bow-like guide part that overlaps the cylinder tube up to the height of the guideways and laterally against the guideways is supported.
  • the two guideways lie on both sides of the longitudinal slot, above the plane of symmetry containing the piston axis, i.e. in more or less immediate vicinity of the longitudinal slot.
  • the cylinder tube is therefore held together in the area of the longitudinal slot by the bow-like guide part of the force transmission element, which significantly increases its resistance to widening of the longitudinal slot.
  • the guideways form a parallel guide. for the force transmission element, via which moments or laterally directed forces acting on the force transmission element, for example, can be properly absorbed and derived directly into the wall of the cylinder tube, without being able to impair the piston or the force transmission element.
  • the cylinder tube carries at least on one side of the longitudinal slot two paired parallel guideways, whereby the number of digits which these reaction forces are introduced into the cylinder tube wall is increased accordingly.
  • the two guideways lying one above the other in pairs can each lie above and below the plane of symmetry containing the piston axis, which is the case it is particularly expedient if reaction forces acting on the force transmission element are to be expected in the circumferential direction of the cylinder tube.
  • the guideways lying on both sides of the longitudinal slot lie with their central axis in a plane running through the piston axis, which is at an angle with the longitudinal central plane of the longitudinal slot approx. 45 °.
  • the guideways can be formed by longitudinal grooves arranged on the cylinder tube outer wall or the guide part, which in a preferred embodiment have a prismatic shape.
  • the guide part is expediently supported via guide strips against the longitudinal grooves, which can consist of a wear-resistant, low-friction material, preferably a plastic material.
  • the guide part is supported against the guideways by rolling elements.
  • the guide part is adjustably supported against the guideways in order to ensure an exact play-free guidance of the force transmission element and to be able to compensate for any signs of wear and manufacturing tolerances.
  • the pressure medium cylinder has a cylinder tube 1, which contains a cylindrical cylinder bore 2, the axis 3 of which is arranged eccentrically with respect to the plane of symmetry of the cylinder tube 1 indicated at 4.
  • the cylinder tube 1 is delimited at the top and bottom by two parallel surfaces 5, 6 and has a longitudinal slot 7 leading into the cylinder bore 2, which opens into the surface 5.
  • a piston 10 is displaceably guided in the cylinder bore 2 of the cylinder tube 1, which is closed at the end by two covers 8, 9, the end of which is sealed at 11 and 12 by means of a sealing sleeve, the inner wall of the cylinder bore 2 and has a central part 13 of smaller diameter.
  • a force transmission element 14 is placed on the part 13, which projects through the longitudinal slot 7 by means of a web-like part 15 and has a bow-shaped guide part 16 connected to the web-like part 15, which in the manner shown in FIG. 2 has a substantially U-shaped cross-sectional shape has and partially engages around the cylinder tube 1 from the outside.
  • two parallel flanges 17 are placed, which serve to connect the driven device, not shown.
  • the power transmission element 14 with all of those mentioned Parts formed in one piece.
  • a multi-part power transmission element 14 is used, the parts (for example 15, 16, 17) of which are screwed or welded together.
  • two prismatic guide grooves 18 of essentially triangular cross-sectional shape are arranged in the outer wall of the cylinder tube 1, which are oriented parallel to one another and extend over the length of the cylinder tube 1 and form guide tracks for the force transmission element 14.
  • Two prismatic guide strips 19 cooperate with the guide grooves 18 ', which are inserted into corresponding grooves on the inside of the legs 20 of the guide part 16 and which consist of a low-friction and wear-resistant material, in particular a plastic material such as polytetrafluoroethylene.
  • the guide strips 19, which together with the guide grooves 1-8 form a parallel guide for the force transmission element 14 and via which the guide part 16 and thus the force transmission element 14 itself is supported against the outer wall of the cylinder tube 1, are by means of set screws 21 on the plane of symmetry indicated at 22 of the longitudinal slot 7 to be readjusted.
  • the cylinder tube 1 can also have further guide grooves 18, two of which are provided at 18a in the present case.
  • the two guide grooves 18a lie below the plane of symmetry 23 containing the axis 3 of the cylinder bore 2 and thus of the piston 10; corresponding ones reach into them
  • Guide strips 19a one of which is illustrated in broken lines in FIG. 2 and which can also be adjusted by means of screws 21.
  • the guide strips 19a are in turn each arranged in an extension, for example schematically indicated at 24, of the associated leg 20 of the guide part 16.
  • rolling elements or roller bearings could of course also be used as support elements, as it is also conceivable to arrange the guide grooves 18 in the legs 20 and to provide the guide strips 19 or the mentioned support elements on the cylinder tube outer wall.
  • the center grooves of the two guide grooves 18 each lie in a plane running through the piston axis 3, which includes an angle of approximately 45 ° with the longitudinal center plane 22 of the longitudinal slot 7. This ensures a uniform absorption of a radial load of the force transmission element 14 by both guide grooves 18.
  • the cover band 27 lies in a longitudinal groove 29 of the surface 5 of the cylinder tube 1 which is symmetrical with the longitudinal slot 7, while the cover band 25 lies outside the piston 10 in a longitudinal groove 30 which is also arranged symmetrically to the longitudinal slot 7, which at the same time gives it lateral guidance and the base 31 of which absorbs the pressure medium.
  • the sealing tape 25 is provided with two wedge-shaped sealing lips or strips 32, which interact with corresponding sealing surfaces 33 in the region of the cylinder bore 2.
  • the cover tape 27 holds the sealing tape 25 by means of two releasable connecting members, which in the form of a web 34 and a cross-section which are essentially wedge-shaped in cross-section and are formed on the sealing tape 25 the cover band 27 are also provided correspondingly wedge-shaped profiled edge-open longitudinal groove 35.
  • the two connecting elements 34, 35 are released from each other during the forward movement of the piston and the spreading of the two bands 25, 27 caused thereby by the band expansion part 26, while they are brought into engagement with one another on the other side of the piston by the piston 10 and the pressure part 28, so that they assume the state of FIG. 3.
