Definitions

  • the invention relates to a pressure-actuated linear drive according to the preamble of patent claim 1.
  • linear drives are shown and described in various embodiments, for example in the documents DE-PS 14 50 723, DE 27 18 528 A1 and DE 28 16 546 A1.
  • These known linear drives have the disadvantage that they are only suitable for a fixed, fixed installation of their guideway and a change in the course of the path is only possible with considerable expenditure of assembly time and new parts.
  • the present invention is therefore based on the object of providing a pressure medium-actuated linear drive which can be produced cost-effectively, which enables a problem-free variable construction and can be laid in any horizontal and / or vertical curves.
  • the flexible guideway and the flexible tubular hollow body of the linear drive according to the invention are made in one piece, i.e. these two components are non-positively and / or positively connected to form a practical unit.
  • This can be implemented particularly expediently in that the guideway and the tubular hollow body form a flexible profile strand produced by coextrusion, in particular in such a way that the tubular hollow body is integrated into one side of the profile strand as a channel running through in the longitudinal direction.
  • the cross-sectional portion of the profile strand forming the guideway is formed from a relatively hard polymer, while the part forming the tubular hollow body has an outer wall made of a particularly elastic and flexible material.
  • the tube-like hollow body can, however, also be designed in the usual way as a separate tube and - in particular by means of a molded-on keder strip - can be positively connected to the guide track. Furthermore, it may be expedient to construct the wall of the tubular hollow body in such a way that it has a soft inner layer and, in contrast, a harder outer layer, which improves the unrolling of the squeezing roller and reduces wear.
  • a flexible braided strength member is then preferably inserted between the inner layer and the outer layer, the braiding angle of which is adapted to the requirements with regard to the neutralization of the axial forces.
  • the guideway 1 forms a one-piece unit with the tubular hollow body 2 in the form of a profile strand formed entirely from flexible, crosslinked or thermoplastic elastomers, on which the transport device 3 rolls.
  • the polymeric materials for parts 1 and 2 are selected specifically for the task, that is, part 1 is made of a relatively hard, flexible material, while part 2 is made of a very flexible, elastic material. Both parts can be manufactured separately and subsequently welded together. Gluing united be, or they form from the outset a unit produced by coextrusion.
  • the pinch roller 5 is arranged in the upper part of the transport device 3 and presses the tubular hollow body 2 against the guideway 1 and squeezes it tightly.
  • the tubular hollow body 2 is designed as a separate component and is positively connected to the guideway 1 by means of a molded-on welt strip 7.
  • the tubular hollow body 2 is pressed together here by the pinch roller 5 and a counter roller 4 assigned to it in pairs.
  • Figures 4, 5 and 6 show a particularly advantageous embodiment of the invention, which is characterized in that particularly high propulsive forces can be achieved with it.
  • it has a tubular hollow body 2 and 2 'above and below the guideway 1, to each of which a pinch roller 5 or 5' mounted in the transport device 3 is assigned.
  • a pair of guide rollers 6 and 6 ' is provided, which rolls on the guide track 1.
  • the tubular hollow bodies 2 and 2 ' which are squeezed tightly by the pinch rollers 5 and 5' perpendicular to the guideway 1, are also positively connected to the guideway 1 in this embodiment by molded-on keder strips.
