Definitions

  • the invention relates to a pressure medium cylinder with an end-closed, longitudinally slotted cylinder tube, in which a sealed piston is guided so as to be longitudinally displaceable, which carries a force transmission element projecting outward through the longitudinal slot, the longitudinal slot of the cylinder tube in the longitudinal direction of the cylinder being arranged in the piston area under the piston area inside the cylinder tube Power transmission element passed and sealed on both sides of the piston in contact with a sealing surface of the cylinder tube inner wall is sealed and covered on the cylinder tube outside by a flexible transmission tape in the area of the force transmission element passing through or through it and on both sides of the force transmission element on the cylinder tube outer wall.
  • Hydraulically or pneumatically operated working cylinders of this type have no piston rod and are therefore characterized by a short installation length and the elimination of the disadvantages that are otherwise associated with the piston rod emerging from the cylinder, for example damage to the surface, buckling of the piston rod, etc.
  • force exerted on the piston by the pressure medium is transmitted to the device to be driven via the force transmission element which is arranged directly on the piston and projects outward through the longitudinal slot of the cylinder tube.
  • the pressure chamber located on both sides of the piston is sealed in the axial direction of the cylinder tube by sealing rings or sleeves of the piston, while the longitudinal slot of the cylinder tube is sealed in this area by the sealing tape which is guided in the pressure-free area between the piston seals under the force transmission element.
  • the sealing strip which has an approximately rectangular cross-sectional shape, lies in a longitudinal groove arranged on the inside in the region of the longitudinal slot, which forms flat contact surfaces and lateral guide surfaces for the sealing strip.
  • the sealing tape is pressed against the bearing surfaces by the pressure medium pressure prevailing in the pressure chambers, precautions must be taken, as practical experience has shown, to prevent the sealing tape from sagging into the pressure chamber when depressurized, because otherwise at a temporary leak occurs when the pressure medium is applied. To this extent, no precautions have been taken with this pressure medium cylinder.
  • the situation is similar in a pressure medium cylinder known from DE-A-2453948, in which a flexible strip is additionally glued onto the outside of the cylinder as dust protection and has an elastically self-closing longitudinal slot that allows the passage of the force transmission element.
  • a pressure medium cylinder known from DE-C-846 493, in which a sealing strip with an essentially U-shaped cross-sectional shape is used, the flanges of which can enter into corresponding recesses on the inner wall of the cylinder tube, in order to thereby seal the pressure chambers improve and at the same time increase the resistance of the cylinder tube against expansion.
  • the production of the parallel recesses on the inner wall of the cylinder tube is associated with considerable manufacturing outlay, apart from the fact that the piston requires special training in order to properly insert the sealing tape with its flanges into the recess.
  • the arrangement has already been made in a pressure medium cylinder known from DE-A-2 162 572 in such a way that the cylinder consists of a non-magnetized material and at least on one of the two parallel wall areas delimiting the longitudinal slot Has magnetic body that attract the sealing material of the sealing tape consisting of magnetizable material.
  • a metallic sealing tape is, however, not very suitable for sealing liquids because of the unavoidable micro leakage, so that practically only compressed air can be used as a pressure medium.
  • the thin metal tape serving as a sealing tape is not guided laterally through the magnetic body, which entails the risk that the sealing tape can occasionally experience a lateral offset with respect to the longitudinal slot, which can lead to the so-called tape explosions feared because of the associated risk of accidents.
  • FIG. 3 In one embodiment (FIG. 3) of this German published patent application, it is known to provide on the outside of the cylinder tube a further, also metallic cover strip covering the longitudinal slot on both sides of the force transmission element, which has the task of keeping the longitudinal slot closed to the outside in order to to prevent dirt from entering the longitudinal slot.
  • This metallic masking tape is also held by magnetic bodies. The magnetic holder both inside and outside the cylinder tube and the profile-ground steel strips require a large amount of production.
  • a pressure medium cylinder in which a relatively thin cylindrical lining of the cylinder is used to seal the longitudinal slot the interior is made of plastic material or metal, the longitudinal edges of which either abut one another in a sealing manner or overlap one another, the lining being pressed against the wall of the cylinder in a sealing manner by self-suspension.
  • the longitudinal slot On the outside, the longitudinal slot is protected by rubber strips against the ingress of dust or the like, which are pressed together under the effect of their own elasticity.
  • a lining arranged in the cylinder interior influences the sealing conditions of the pressure chambers through the piston; it is also subject to considerable wear resulting from the piston movement, both of which are undesirable.
  • the object of the invention is therefore to provide a pressure medium cylinder of the type mentioned, which is characterized by a perfect sealing of the pressure chambers located on both sides of the piston with little manufacturing effort.
  • the pressure medium cylinder according to the invention is characterized in that in the longitudinal direction of the cylinder, on both sides of the piston, the sealing tape is held in contact with the associated sealing surface by the cover tape by means of interacting, detachable connecting elements which project through the longitudinal slot and extend over the length of the tape, and the connecting elements depending on the longitudinal movement of the piston in each case continuously in front of that piston side that is facing the shrinking cylinder space, detached from one another and brought into engagement with one another on the other piston side.
  • the pressure medium cylinder is therefore also ideally suited for liquid pressure medium. Since the sealing tape is held through the already existing longitudinal slot, there is also no need for separate mounting elements to be arranged on the cylinder, with the result that the production outlay for the new pressure medium cylinder can be kept very small.
  • the connecting elements consist of at least one web, which runs in the longitudinal direction of the cylinder, is arranged on the sealing band or the cover band in the radial direction of the cylinder tube, has a cross-sectional profile and an associated web which also runs on the other band in the longitudinal direction of the cylinder, corresponding to the web cross-section form-fitting encompassing, also in cross-section profiled longitudinal groove, the side walls of which can be elastically expanded to accommodate the web.
  • cross-section of the web and the longitudinal groove have an at least partially directed wedge-shaped profile shape in the direction of the cylinder axis, and the wedge-shaped parts of the web and the longitudinal groove are arranged behind one another, so that when connecting elements are joined together, a positive connection between these results.
  • the profile cross section of the longitudinal groove and / or of the web can then have a wedge-shaped part facing the respective band, radially parallel to the cylinder tube, essentially parallel, straight-flanked part, while the web on its free, radially directed to the cylinder tube and facing away from the associated band end a radially Conver g rendesEinteil IE has, thereby facilitating the joining of the connection elements and their engagement can be improved.
  • the sealing tape expediently has a guide part, which is supported on two bearing surfaces of the cylinder tube on both sides of the longitudinal slot and is laterally guided by radially arranged guide surfaces and on which the associated connecting element is arranged.
  • this guide part in cooperation with the bearing surfaces can effect the entire seal, but an improvement in the sealing conditions can be achieved if the guide part on the side of the guide part facing the interior of the cylinder tube, symmetrically to the plane of symmetry of the sealing tape, has two elastically movable sealing lips are connected, which cooperate with sealing surfaces of the cylinder tube wall, which are arranged, if appropriate, recessed in the cylinder tube.
  • sealing lips are advantageously movably held at their roots on the guide part and have a wedge-shaped decreasing cross-sectional shape when directed away from their roots.
  • the surface of the sealing tape facing the cylinder axis can be designed to complement the inner circumferential surface of the interior of the cylinder tube
  • the force transmission element has a band-expanding part which extends in a wedge-shaped manner on both sides in the longitudinal direction of the cylinder tube and which lies between the cover and the sealing band.
  • the force transmission element in the longitudinal direction of the cylinder tube can have a pressure element acting on the outside of the cover band from the outside and pressing it onto the cylinder tube outer wall, which is arranged in each case in the length region of the piston and in cooperation with the piston - on the piston side trailing during a piston movement - the connecting elements with one another engages.
  • the masking tape and / or the sealing tape can consist of an elastic plastic material, the properties of which are chosen with regard to the mechanical stresses occurring and the pressure medium used. In principle, however, it is also conceivable to alternatively use fabric-reinforced rubber material or the like for this purpose.
  • the pressure medium cylinder shown in FIGS. 1 to 3 has a cylinder tube 1 which contains an interior 2 in the form of an eccentrically arranged cylinder bore and is formed with a continuous longitudinal slot 3.
  • the cylinder tube 1 is pressure-tightly closed at both ends by end caps 4; in it a piston 5 is displaceably guided, which carries a sealing collar at each end at 6 and 7 and is thus sealed against the inner wall of the cylinder bore 2.
  • the piston is designed at 8 with a reduced diameter.
  • a force transmission element 9 is screwed to it, which has a web-like part 10 which leads outwards through the longitudinal slot 3 to the side and to which a bracket 11, which laterally overlaps the cylinder tube 1, is connected, on which two parallel flanges arranged at a distance from one another 12 sit, which are used to couple the power transmission element 9 to a device, not shown, actuated by the pressure medium cylinder.
  • the bracket 11, which has an essentially U-shaped cross-sectional shape, is provided in the region of its legs 13 with two guide strips 14 inserted into corresponding longitudinal grooves, which are adjustable by means of set screws 15 and are displaceably guided in corresponding longitudinal grooves 16 of the cylinder tube 1.
  • the two legs 13 can also be extended downwards, as indicated at 17 in FIG. 2, and carry additional guide strips 14a which cooperate with corresponding longitudinal grooves 16a.
  • the guide strips 14 result in a parallel guide for the force transmission element 9 and at the same time prevent the cylinder tube 1 from expanding in the region of the longitudinal slot 3.
  • a sealing tape 18 Arranged in the cylinder interior 2 is a sealing tape 18 consisting of a flexible, elastic plastic material, which is anchored at the ends in the two end caps 4.
  • the sealing tape 18 serves to seal the longitudinal slot in the area of the pressure chambers 19, 20 between the piston 5 and the two end caps 4 and the pressure medium cylinder and extends over the entire length of the cylinder tube 1.
  • the sealing tape 18 has a base or guide part 21 of essentially rectangular cross-sectional shape, which can rest on both sides of the longitudinal slot 3 on a flat bearing surface 22 arranged at the bottom of a longitudinal groove and is guided laterally by two guide surfaces 23 formed by the groove side walls.
  • two wedge-shaped elastic sealing lips 24 with an acute angle in cross-section are arranged on the guide part, and at their roots - at 250 - the guide part 21 is formed so as to be movable.
  • the sealing lips 24 bear against associated sealing surfaces 25 incorporated into the wall of the cylinder interior 2, the arrangement being such that the sealing tape 18 complements the outline of the cylinder interior 2 without gaps in the manner shown in FIG. 3 in particular.
  • the sealing tape 18 On the upper side of the guide part 21, the sealing tape 18 carries a molded central web 26 forming a connecting element, which projects into the longitudinal slot 3 and is arranged symmetrically to the latter.
  • the longitudinal slot 3 On the outside of the cylinder tube 1, the longitudinal slot 3 is covered by a flexible cover band 27 consisting of a flexible elastic plastic material, which also extends over the length of the cylinder tube 1 and is anchored in the end caps 4 at both ends.
  • the cover band 27 is approximately rectangular in cross section and lies in a corresponding longitudinal groove 28 of the cylinder tube 1, from the bottom of which the longitudinal slot 3 opens.
  • a second connecting element is arranged in the form of a longitudinal groove 30 delimited by two molded-on parallel legs 29, which has a substantially U-shaped cross section and, like the web 26, extends over the entire length of the cover band 27 or Sealing tape 18 extends.
  • the web 26 is formed at its root with a parallel and straight-flanked part 31, which is adjoined by a wedge-shaped part 32 that widens outwards, on which a converging insertion part 33, which in the present case is approximately trapezoidal in cross section, but possibly also rounded follows.
  • a converging insertion part 33 which in the present case is approximately trapezoidal in cross section, but possibly also rounded follows.
  • they wear the longitudinal groove 30 delimiting legs 29 on their inside wedge-shaped parts 34 which lie opposite each other and converge towards the groove opening.
  • the arrangement is such that the web 26 in the manner shown in FIG. 4 with elastic lateral remindwei chen the leg 29 of the cover tape 27 can be pressed continuously into the longitudinal groove 30, whereby a firm connection between the cover tape 27 and results in the sealing tape 18, since the wedge surfaces 34, 32 engage behind one another in the assembled state of the connecting elements and produce a positive connection.
  • the bevelled insertion part 33 facilitates the insertion of the web 26 into the longitudinal groove 30, while the straight-sided parts 31 and 34a ensure that the wedge-shaped parts 32, 34 can come into contact with one another without any problems.
  • a plurality of webs and longitudinal grooves arranged parallel to one another could of course also be provided in another embodiment, not shown, as would also be conceivable for the web 26 on the cover band 27 and the longitudinal groove 30 instead to provide on the sealing tape 18.
  • the sealing tape 18 is passed through an opening 35 (FIGS. 1, 2) under the force transmission element 9, which has a tape expansion part 36 which is arranged in the region of the piston part 8 and extends in a wedge-shaped manner on both sides in the longitudinal direction of the cylinder tube, over the top of which the cover tape 27 is guided, that the band expansion part 36 lies between the two bands 18, 27.
  • the force transmission element 9 carries, in the region of its two ends, a pressure element 37 which acts on the cover band 27 and presses it against the cylinder tube wall, in the manner of a roller, which - as can be seen from FIG. 1 - is essentially above the sleeve 6 or 7 supporting piston part is arranged.
  • the sealing sleeve 7 On the other side of the piston (on the right in FIG. 1), when the piston 5 moves to the left, the sealing sleeve 7 carries the piston part and the right pressing member 37 continuously engages the web 26 of the sealing tape 18 into the longitudinal groove 30 of the cover tape 27, so that the right pressure chamber 20 is always properly sealed.
  • the pressure medium cylinder can be operated with any gaseous or liquid pressure medium.
