Definitions

  • the invention relates to a fluid-operated rotary drive, with one extending between two head pieces Hose body, the one attacking the two head pieces Power transmission structure is associated with Fluid exposure to the interior of the hose body relative rotation between the two head pieces evokes.
  • US 3,638,536 already has a fluid-operated one Rotary drive of the type mentioned initially proposed in which the rotational movement by an axially between two headers extending and with an integrated Power transmission structure provided hose body is produced.
  • the tube body is there as a contraction tube designed for the application of internal pressure expands radially and at the same time via the power transmission structure pulls the two head pieces towards each other.
  • the is tapped Angle of rotation relatively small, so that the possible uses this known rotary actuator quickly set limits are and the practical technical benefit in question can be put.
  • the support device choose the axial relative movements between prevented the two head pieces in both axial directions.
  • the invention preferably rotary movements and torques with a defined assignment of operating pressure, Angle of rotation and torque while avoiding axial Movements generated as another dependent variable become.
  • the support device To ensure reliable operation of the rotary drive even then to ensure if the headers are not purely axial Applying forces, it is advantageous to use the support device to be interpreted as being between the two head pieces absorb transverse forces and / or bending moments can. To compensate for these loads, too external institutions are used, for example the objects to be rotated relative to each other, if they are stored accordingly. To a universal To enable the use of the rotary actuator is recommended However, there is also an integration of these support functions into the support device itself.
  • the support device not necessarily as an immediate component of the Rotary drive must be executed. Your function can be corresponding design of the relative to each other to twisted objects themselves or from other suitable external means.
  • the power transmission structure is preferably a strand structure running across a multitude themselves between flexible headers extending the head pieces has, which is in particular helical between extend the two headers and the for the relative Rotational movement when the internal pressure is applied Hose body are responsible. It would be conceivable that Tension strands through warp-like cross strands or through a whatever kind of networking in their relative position to fix. However, it has proven to be particularly beneficial proved the strand structure exclusively running side by side with the same longitudinal orientation To build train lines. Their position is convenient stabilized in that they are at least partially in the tube body are embedded, for example by Vulcanization.
  • the limiting means can be on the outer circumference of the hose body be placed, but will preferably be at least partially and especially completely in the tube body integrated.
  • the connection between the tubular body 2 and a respective one Head piece 3, 4 is designed to be fluid-tight.
  • the Hose body 2 therefore defines together with the two Headers 3.4 an interior 8, which if necessary with the actuating fluid pressure medium, e.g. Compressed air, can be acted upon.
  • the actuating fluid pressure medium e.g. Compressed air
  • the fluid supply is guaranteed by in the interior 8 flowing fluid channel means 12.
  • They contain in the embodiment, one of the two head pieces 3,4, in the present case the rear head piece 4, penetrating Fluid channel 12 ', the outer end of which is schematic indicated connection means 11 to a further Fluid line 13 is connected, via which both a supply as well as a discharge of the print medium with respect to the Interior 8 can be done. It is understood that for the Feeding and removal of the pressure medium if necessary separate fluid channels can be provided.
  • the strand structure 6 could be in relation to the tubular body 2 be formed separately, the latter on the outer circumference completely encloses, for example based on the model the EP 0 161 750 B1. However, this is also preferable in the exemplary embodiment realized design in which the Strand structure 6 at least partially and preferably completely is integrated in the hose body 2.
  • the Tension cords 7 are in the material of the hose body 2 embedded so that the hose body 2 and the power transmission structure 20 form a structural unit that together can be fixed to the head pieces 3.4. Through the attachment the hose body 2 also becomes the force transmission structure 20 fixed to the headers 3.4 so that they can exert 3.4 tensile forces with respect to these head pieces.
  • the support device 18 can thus be seen with regard to the direction of action of the support function assumed by it taking into account the work area of Strand structure 6 can be designed. Occur in operation only Sloping angle "s" above 54.7 °, the support can become preventing the headers from being removed from each other 3.4 limit. However, the angular range lies always below 54.7 °, the design can be made so that only a support to prevent one axial approach takes place. However, it is already over Because of the stability of the rotary drive 1 as such very much reasonable regardless of the helix angle that occurs during operation a support that is always effective in both axial directions to provide, as is the case with the embodiment is.
  • the support elements 22, 23 can also be used to stabilize the Contribute hose body 2 with rotary drive 1 deactivated.
  • the Hose body 2 in the depressurized state of its interior 8 bears coaxially on the outer surfaces of the support elements 22, 23.
  • Suitable channel connections 34 in the head pieces 3.4 ensure the desired fluid access despite everything to the inner surface of the hose body 2.
  • This form of implementation provides that the limitation means 35 around one or more ring-like or belt-like Elements are arranged coaxially to the tubular body 2 are. If there are several elements, one is created axially spaced distribution along the length of the Hose body 2 away. When pressurizing the Hose body 2 are thus only those between adjacent ones Limiting means 35 lying wall areas of the hose body 2 capable of radial expansion. On in this way the tubular body 2 is in the activated state over a bulged outer contour, whereby however the diameter increase compared to the deactivated Condition is much lower than in one Design without means to limit expansion.
  • hose body 2 To specify a certain maximum angle of rotation, you can in the interior 8 of the hose body 2 or radially outside the hose body 2 means may be provided (not shown), the radial deformation of the hose body 2 limit.
  • the means preferably assume a stop function and could therefore also be used as a sling be designated.
