Definitions

  • the invention relates to a Ausfahrêt, in particular for a submarine, with the features specified in the preamble of claim 1 len.
  • Such an extension device is described for example in DE 195 35 873 Al.
  • This extension device has a circular, cylindrical shaft in which a piston-shaped guide part of the extension part is guided.
  • This guide part forms with the inner surface of the shaft over the entire inner circumference of the shaft a Gleitla- ger, which ensures a safe and precise storage and management of the extension part in the shaft.
  • this embodiment requires a high dimensional accuracy of manhole and guide part, which is associated with considerable manufacturing effort.
  • a Ausf ⁇ hrêt with a prismatic shaft with a rectangular inner cross section is known.
  • the guidance of the extension part of this extension device in the shaft takes place in the four corners of the inner cross section of this shaft in each case via two bearings.
  • a disadvantage of this leadership of Ausfahrteils is that the extension part can tilt during retraction or extension in the shaft and can not be properly moved out of the shaft in this way.
  • the invention has the object to provide a Ausfahrêt, on the one hand production technology can be made as simple as possible and on the other hand has the highest possible reliability.
  • the Ausfahrfind invention is particularly intended for use in a submarine. It has a shaft and an axially movable in the shaft extension part. Under the Ausfahrteil is the movable part of the Ausfahr réelles to understand on which or in the projectilede from the submarine objects are stored.
  • three linear guides for forming a three-point guide of the extension part are provided in the shaft between the shaft and the extension part. That is, the extension part is statically determined in the shaft in a plane transverse to its extension direction and so on the one hand against any movement transverse to the extension direction secured.
  • the extension part is statically determined in the shaft in a plane transverse to its extension direction and so on the one hand against any movement transverse to the extension direction secured.
  • a further advantage of the extension device according to the invention is that the condition of the inner wall of the shaft with regard to the movability of the extension part is at most in the areas of importance, in which the three linear guides between the shaft and the Ausfahrteil are arranged, so if necessary, toller tolerances with regard to the plane parallelism and the distance of the guide surfaces from each other must be adhered to only in these areas, which represents a considerable simplification in terms of production compared to the state of the art.
  • the inner cross-sectional contour of the shaft is basically arbitrary, as long as it allows a three-point guidance of the extension part in the shaft.
  • shafts with a round and preferably circular inner cross section are preferred.
  • the shaft can be produced from a cost-effective tubular semifinished product, wherein the round cross-section gives the shaft a particularly high flexural rigidity transversely to its longitudinal extent.
  • the three linear guides for guiding the extension part in the shaft can basically be designed both as linear roller guides and as linear sliding guides, with linear sliding guides being preferred because of their comparatively simple and robust construction.
  • a sliding surface can be formed directly on the extension part, which slides along a shaft-side sliding track during the movement of the extension part.
  • sliding shoes are arranged on the extension part, each one part each Line ⁇ r Entry form.
  • the sliding shoes are replacement parts, if necessary, z. B. in a wear of the sliding shoes formed on the sliding surfaces, easily removed and replaced with new sliding shoes.
  • the sliding blocks are preferably arranged on the extension device in the region of its extendable part, that is to say on the region on which or on which objects to be ejected from the submarine are mounted.
  • This may be, for example, the free end of a piston rod attached to the piston of a piston-cylinder arrangement.
  • This is advantageous in that the extension part is supported in this extension in each extended position substantially over its entire length on the shaft, which makes the arrangement of the extension part particularly rigid and leads to any occurring moments are introduced directly into the outer structure. In a torque-free connection of the hydraulic cylinder or a spindle these are not subjected to additional bending moments.
  • an expedient embodiment of the Ausfahrteils is provided in which the Ausfahrteil normal to the extension direction, preferably star-shaped Arms are formed, at the free ends of the sliding shoes are arranged.
  • the arms thus serve to bridge the distance from the extension part to the inner wall of the shaft and to support the extension part on the shaft. They are dimensioned such that the arranged on the free ends of the arms sliding shoes come into sliding contact with the shaft side slideways.
  • To form a three-point guide of the extension part can, in particular in a shaft with a round inner cross-section each two adjacent arms enclose an angle of substantially 120 °.
  • the sliding shoes can be mounted normally to the extension direction resiliently at the free ends of the arms. That is, an elastic bearing of the sliding shoes is provided, which can absorb forces transversely to the extension direction of the extension part, without these transverse forces exerting a significant influence on the linear guide owing to the damping properties of the suspension used, which is particularly the case in the case of a shock load on the linear guide Ausfahrschuls is an advantage.
  • the sprung mounting of the sliding shoes allows the sliding shoes to contact the corresponding shaft-side sliding tracks under prestress. In this way, the safe investment of the shoes on the shaft side slideways is always guaranteed.
  • At least one elastic element is preferably arranged between the free end of the arm and the sliding shoe, which may be e.g. can act around a Elastomer- and / or a spring element.
  • the good damping properties of rubber-like elastomer elements in the case of shock loading of the extension device and the ability of these elements to compensate for manufacturing and assembly tolerances prove to be particularly advantageous.
  • the sliding shoes are expediently arranged to be adjustable transversely to the extension direction.
  • the distance of the sliding shoes from the extension part can thus be changed to some extent.
  • the inner wall of the shaft forms the slideways for the sliding shoes.
  • the slide rails can be formed for example by square flat strips, which are arranged aligned on the inner wall of the shaft in the extension direction of the extension.
  • At least one stop which tapers wedge-shaped in the extension direction, and a correspondingly formed stop on the extension part are advantageously provided on the shaft side.
  • This can be on the shaft side as well as on the extension part side by an annular stop, which extends around the entire inner circumference of the shaft or around the entire outer circumference of the extension part.
  • the Ausrioseils in the shaft and its self-centering and its defined self-adjustment in the lower end position can be provided in the slot advantageously at least one in the retraction wedge-shaped tapered stop and the Ausfahrteil a corresponding second stop.
  • This can be both a shaft side and a ⁇ usf ⁇ hrteil solutionen annular stop as well as three equally spaced from each other stops on the shaft and the Ausfahrteil act.
  • Both the stops for limiting the extension path and the stops for limiting the entry path can optionally be made adjustable with respect to their vertical position as well as with respect to their angle to the horizontal plane.
  • Fig. 1 in a simplified schematic representation of an extension device in a longitudinal section
  • the Ausfahr réelle shown in the figures is arranged on the outside of a pressure hull 2 of a submarine. It has a hollow-cylindrical shaft 4, in which a telescopic cylinder 6 is arranged concentrically to a central axis A of the shaft 4. Typically, the telescopic cylinder 6 may optionally be arranged eccentrically in the shaft 4. The extendable piston rod of the telescopic cylinder 6 forms a Ausfahrteil 8 of the Ausfahr réelles.
  • a shoulder 10 is formed, on which an annular collar 12 is supported.
  • This collar 12 extends beyond the outside of the extension part 8 to the outside and serves for the attachment of three star-shaped radially outwardly directed arms 14.
  • the center axes B of each two adjacent arms 14 form an angle of 120 °.
  • a component 16 extends in the direction of the pressure body 2 to spring back, wherein one of the inner wall of the shaft 4 facing Side 18 of the component 16 is arranged substantially plane-parallel to this inner wall.
  • a sliding shoe 20 is arranged in each case.
  • the sliding shoes 20 are in sliding contact with slide rails 22, which are arranged corresponding to the position of the sliding shoes 20 on the inner wall of the shaft 4, are aligned parallel to the central axis A of the shaft 4 and extend approximately over the entire length of the shaft 4.
  • the slide rails 22 are formed by square flat strips. Together, the three sliding blocks 20 and the three slide rails 22 form linear guides in the form of a statically determined three-point guide.
  • the sliding shoes 20 are not attached directly to the Gleitschuhfactn 24. Instead, an elastomeric element in the form of a rubber pad 28 is disposed between the sliding shoes 20 and the Gleitschuhfactn 24. These rubber pads 28 give the linear guides a defined elasticity transversely to the extension direction of the extension part 8. In addition, the rubber pads 28 can ensure the safe investment of the sliding blocks 20 on the slide rails 22 with a certain bias.
  • stops 30 are arranged corresponding to the radial orientation of the arms 14. These stops 30 have a wedge shape, wherein the arms 14 zugege- turned side of the stops 30 beveled to the central axis A of the shaft 4 is formed, such that the stops in the direction of the pressure hull 2 taper transversely to the central axis A.
  • a stop 32 is arranged on the arms 14.
  • the stops 32 which are arranged on the side 18 of the components 16, are wedge-shaped.
  • the inner wall of the shaft 4 directly facing side of the stops 32 is chamfered, such that the stops 32 taper in the extension direction of the extension part 8 transversely to the central axis A.
  • the wedge shape of the stops 30 and 32 allows self-centering of the extension part 8 in its end position of the extension movement. Furthermore, due to the wedge shape of the stops 30 and 32 large forces can be introduced from the extension part 8 in the shaft 4, which increases the shock resistance and rigidity of the extension part 8 in the end position.
  • a stop 34 is arranged on the side 18 of each component 16. Also, one side of the stops 34 is chamfered to the central axis A of the shaft 4 is formed. The chamfer takes place in the direction of the pressure body 2 in the direction of the central axis A. On the pressure body 2, three further stops 36 are arranged, whose position corresponds to the position of the stops 34. The stops 36 also have a chamfer, which is designed so that the stops 36 in cooperation with the stops 34 in the retracted end position of the extension part 8 cause its self-centering in a defined end position in the shaft 4.
