Definitions

  • the present invention is a Rotary and / or lifting device according to the preamble of Claim 1.
  • Cylinder-piston arrangements are usually used to generate linear strokes or back and forth movements.
  • a double-acting rotating cylinder with swivel wing in combination with a linear cylinder has been proposed for the realization of rotary and lifting movements.
  • the angle of rotation is fixed and can only be changed manually.
  • Such cylinder-piston assemblies are relatively complex and therefore expensive to manufacture. A certain susceptibility to failure cannot be completely ruled out.
  • the pistons and cylinders moving against each other are provided with seals which are exposed to friction and wear when the arrangement is operated. Additional measures are required for elastic damping in the end positions of the lifting and / or rotating movement.
  • claim 1 substantially Invention consists in the creation of a simple turning and / or Lifting device, which features lifting / lowering, Turning and steaming combined.
  • Rotating and / or lifting device 2 preferably from a hollow cylindrical or barrel-shaped structure 4 made of rubber or a comparable elastomer material.
  • a cone 6a, 6b for attachment one cover plate 8a, 8b each by means of one Clamping ring 10a, 10b.
  • Cover plates 8a, 8b can also - similar to air springs -
  • At least one end (each) has a rolling piston be provided.
  • the hollow cylindrical or barrel-shaped structure 4 can - like the bellows of a vehicle air spring - be made up of several (e.g. two) layers lying one on top of the other. It is essential to the invention that the wall of the hollow cylindrical or barrel-shaped structure 4 is provided with at least one cord or fabric layer 12 (FIGS. 1a / 1b, section A).
  • the inserted threads 12 are - in contrast to the rubber mixture - practically inextensible.
  • the threads 12 In the case of a plurality of layers lying one on top of the other, the threads 12 have the same (one-dimensional) direction of action, with a thread angle ⁇ ⁇ 0 with respect to the longitudinal axis 14 (or ⁇ 90 ° with respect to the at least one clamping ring 10a, 10b).
  • a double layer offers higher pressure resistance and a longer service life.
  • the hollow-cylindrical or barrel-shaped structure 4 is sealed airtight and pressure-tight by the cover plates 8a, 8b (or rolling
  • the Wall of the hollow cylindrical or barrel-shaped structure 4 Apart from the cord or fabric insert 12, which the Wall of the hollow cylindrical or barrel-shaped structure 4 holds practically inextensible in an oblique-angled direction, is the wall due to the elastic properties of the Elastomeric materials in all other directions below Stretchable and therefore also shearable.
  • the extensibility lies - depending on the chosen elastomer material - between minimal 200% and a maximum of 1000%.
  • the structure 4 tries to set the largest possible volume 16 with the smallest possible surface enlargement while maintaining the length of the incorporated threads 12. This is done in such a way that the threads 12 incorporated into the wall aim at an angle of 90 ° with respect to the clamping rings 10a, 10b.
  • the end cover plates 8a, 8b or rolling pistons exert a rotary 18 and / or lifting movement 20 relative to one another.
  • the angle of rotation 18 and the stroke 20 of this rotation and / or Lifting device 2 can depend on the pressure (bar) and of the original thread angle ⁇ can be chosen freely.
  • a roll-off piston (as in a vehicle air spring) is provided, a correspondingly larger stroke 20 can be realized, which would otherwise only exist due to the shearability / extensibility of the elastomeric material.
  • a vertical guide can also be provided for precise axial orientation of the lifting movement 20. This can e.g. B. by an enveloping cylinder, by pivoting handlebars - as in a vehicle spring - or by a piston / cylinder arrangement.
  • the device 2 combines the three Functions turning, lifting and steaming in one Component.
  • the stroke rotary movement 18, 20 can in Depending on the pressure can be controlled variably.
  • the rotating and / or lifting device according to the invention is can be used wherever pneumatic rotary or Rotary-linear movements initiated via cylinders or be carried out.
  • FIG. 2 shows one pure turning device 22.
  • the basic structure exists to a certain extent, mirrored to each other arranged air springs, each with a rolling bellows 24a, 24b, each a rolling piston 26a, 26b and one in the Plane of symmetry 36, common "cover plate" 28.
  • the special thing about this arrangement 22 is that the two bellows 24a, 24b with each other oppositely directed cord inserts are provided.
  • the common cover plate 28 is rotatable about its axis 30 stored.
  • the two rolling pistons 26a, 26b are fixed, d. H. they are neither rotatable nor axial slidable.
