Definitions

  • the invention relates to an activatable by Fluidbeetzschlagung actuator, with a extending between two headers contraction tube which is acted upon fluid loading of its inner tube in the sense of a radial expansion and at the same time in the sense of a mutual approach acting axial tensile forces on the headers, wherein the Contraction tube comprising a tubular body made of material having rubber elastic properties and a strand structure embedded in a coaxial arrangement in the wall of the tubular body, and wherein the contraction tube is attached to at least one headpiece by being clamped with its associated tube end portion in an annular nip, that of the outer circumference of an axially immersed in the contraction tube head inner part and the inner circumference of a contraction tube at the level of the header inner part coax ial encompassing head piece outer part is defined.
  • WO 00/61952 A1 actuator of this type is composed of a rubber elastic hose body and a coaxial embedded in the hose body strand structure composite contraction hose with two hose end portions each attached to a head piece.
  • the head pieces contain a head piece inner part which dips into the contraction hose and a head piece outer piece which engages over the associated hose end portion and which is designed in the manner of a cap nut and screwed to the head piece inner part.
  • an annular clamping gap is defined, in which the associated hose end portion is clamped by pressing. The pressing process results from the axial screwing of the two parts of the head piece in conjunction with a conical course of the clamping gap.
  • the tube interior of the contraction tube is filled with pressurized medium under a certain operating pressure. This causes a radial expansion of the contraction tube with resulting axial contraction tendency, so that tensile forces are exerted on the head pieces, which act on the head pieces in the sense of mutual approach. In this way, external structures or components, which are fixed to the headers, clamped together and / or moved relative to each other.
  • the clamping connection between the contraction tube and the head pieces has proven to be problematic when occurring especially very high tensile forces.
  • the clamping surface of one of the clamping units is provided with a plurality of projections, which can be pressed into the material of the hose body, there is a risk that the contraction tube is pulled out of the clamping gap under extreme loads.
  • the surfaces adjacent to the hose body can have a finely structured surface structure, for example a groove structure, or even a finely distributed structure of punctiform elevations and depressions.
  • this design is associated with increased design complexity, which makes the production more expensive.
  • the outer circumference of the head piece inner part and the inner circumference of the head piece outer part are profiled in the axial direction sawtooth-shaped, wherein the flat tooth flanks of the contraction hose interspersed axial clamping gap opening facing that arranged the two sawtooth profiles are that their teeth at the same axial height lying in pairs radially opposite each other, and that the head piece outer part is formed as under radial deformation with the enclosed by it hose end portion radially compressed compression sleeve.
  • both the head piece inner part and the head piece outer part can dig into the elastic material of the hose body, so that a strong toothing effect occurs, which prevents withdrawal of the contraction tube from the head in question even at high tensile stress.
  • the teeth of the sawtooth profiles are at the same axial height, the embedded in the tubular body strand structure is essentially claimed only on cross-pressing and not bending, so that despite a strong pressing a straight longitudinal profile of the strand structure can be ensured. This counteracts slipping out of the contraction tube from the nip. The risk of damage to the strand structure at the tooth tips is minimized in this way.
  • a further material protection results from the preferably purely radial compression of the two parts of the head piece, whereby axial relative movements between the sawtooth profiles are avoided during assembly, which could lead to damage of the elastic material of the hose body.
  • the compression sleeve is advantageously before the radial compression of the axial clamping gap opposite the front side coaxial plugged onto the headpiece inner part until an axially relative position is achieved by mutually cooperating abutment surfaces in which sets the pairwise radial assignment of teeth of the mutual sawtooth profiles. This allows a very fast production process without expensive adjustments.
  • the compression sleeve has an annular, radially inwardly projecting positioning projection, which dips during radial compression in an annular, radially outwardly open fixing groove of the head piece inner part and in this way the desired specifies axial relative position of the two parts of the head piece.
  • the nip can transition at the axial nip opening axially opposite front into a radially outwardly outgoing, defined between the head piece inner part and the compression sleeve annular gap, which allows the compressed hose body material a damage-free evasion.
  • the sawtooth profiles are preferably arranged so that their generatrices defined by the tooth tips are parallel to one another. This results in a uniform pressure over the entire length of the clamped hose end portion while avoiding local overuse.
  • a further advantage results from a course of the two sawtooth profiles, and thus of the nip, which widens conically to the axial nip opening penetrated by the contraction hose.
  • the inclination with respect to the longitudinal axis of the head piece is here in particular in the range of 2 °.
  • result from this compared to the design according to WO 00/61952 A1 opposite inclination of the nip significantly improved mounting conditions. This is especially true if the diameter of the clamping gap in the region of the axial clamping gap opening is slightly larger than the diameter of the contraction tube in the middle section located between the two head pieces in the deactivated state.
  • the radial distance between the lateral surfaces of the two sawtooth profiles defined by the tooth tips is at least as great as the radial dimensions of the strand structure embedded in the wall of the hose body, preferably even slightly larger, a particularly secure clamping of the contraction tube without risk of damage to the strand structure is possible.
  • the stress of the contraction tube in the region of the axial clamping gap opening can be considerably reduced if the rear end section of the clamping gap located there is tooth-free and has a smooth surface. The sawtooth then ends before reaching the nip opening.
  • the height of the teeth of the sawtooth profiles to be chosen so that it corresponds to about 1 ⁇ 4 of the wall thickness of Schlauchgropers.
  • the exemplified in the drawing actuator 1 includes two axially spaced from each other first and second head pieces 2, 3, which are firmly connected to each other via a linearly extending contraction tube 4. At least in the deactivated state of the actuating device 1, the contraction tube 4 preferably has a substantially hollow cylindrical shape.
  • the contraction tube 4 in the embodiment has an elongated tube body 5 consisting of material with rubber-elastic properties.
  • the material used is in particular rubber or an elastomer material.
  • strand structure 6 is embedded, which completely enclosed by the material of the hose body and which is arranged coaxially to the hose body 5.
  • the structural configuration of the contraction tube 4 preferably corresponds to that described in WO 00/61952 A1.
  • the following explanations to the strand structure 6 are therefore limited to the essentials. For further details, reference is made to the content of the aforementioned document.
  • the strand structure 6 has bendable strands 7a, 7b of high tensile strength arranged in a cross-over configuration. These strands are combined into two strand groups, which contain strands 7a on the one hand and strands 7b on the other, the strands 7a, 7b running side by side within a respective strand group with the same longitudinal orientation.
  • the two strand groups themselves are arranged in a crossover configuration, as indicated in the enlarged section in FIG. 1, which reproduces the strand structure with a radial view with respect to the longitudinal axis 9 of the actuating device 1.
  • the strand groups are kept constantly at a radial distance from each other. Increased friction-causing direct contacts between the strands 7a, 7b of the two groups of strings can be excluded in this way.
  • the contraction tube 4 is with its two axial tube end portions 10 - in the drawing only in conjunction with the cut shown left header 2 visible - so determined on each associated header 2, 3, on the one hand, a fluid-tight connection between the tube body 5 and the relevant Head piece 2, 3 is present and on the other hand by the strand structure 6 tensile forces on the respective head piece 2, 3 are transferable.
  • the tube interior 13 opens at least one fluid channel 14, which passes through the first head piece 2 lying outside the plane of the drawing in the embodiment.
  • the outer end of the fluid channel 14 is formed so that a fluid line, not shown, can be attached, with which the connection to a pressure source can be made.
  • fluidic pressure medium for example compressed air
  • the actuator 1 is operated with gaseous pressure medium, in particular compressed air. It is suitable however, also for operation with hydraulic fluid, such as oil or water.
  • Each headpiece 2, 3 is equipped with force tapping means 17 at an externally accessible location. These are formed in the embodiment of a threaded portion. They allow attachment of the respective head piece 2, 3 to a non-illustrated component. For example, it would be possible to stationary fix the first head piece 2 with its Kraftabgriffsstoffn 17 on a support structure and the other head piece 3 with a relative to the support structure to be moved machine part.
  • the Kraftabgriffsstoff 17 are usually connected to such components, which should be pulled together as needed with a certain force.
  • the operating pressure which builds up in the hose interior 13 when the actuating device is activated effects the contraction hose 4 in the sense of a radial widening. This has the consequence that the contraction tube 4 is acted upon simultaneously in the sense of an axial contraction, wherein the resulting axial tensile forces in the sense of mutual approach to the head pieces 2, 3 act. In this way, on the two head pieces 2, 3 fixed components can be moved relative to each other.
  • the particular movement and deformation behavior of the contraction tube 4 results from the already mentioned integrated Strang Quilt 6. Due to the cross-over configuration, which results in the embodiment of an opposing helical shape of the two strand groups with respect to the longitudinal axis 9 results in diamond-like grid areas. By the internal pressure of the contraction tube 4, a shift in the diamond angle is caused, which ultimately causes the described effect.
  • the contraction tube 4 is firmly clamped with its hose end portions 10 in an annular clamping gap 18 of the respectively associated head piece 2, 3.
  • the nip 18 is located radially between the outer periphery of a head piece inner part 22 and a head piece inner part 22 coaxially enclosing head piece outer part 23.
  • the nip 18 is provided with an axially oriented annular nip opening 24 to the other head 3, the second indicates and engages through the contraction tube 4 in the nip 18.
  • the headpiece inner part 22 is expediently that component of the respective head piece 2, 3, which is provided with the Kraftabgriffsmitteln 17. It emerges with an exemplary bolt-like first attachment portion 25 from the front side a little way into the contraction tube 4, wherein the outer periphery of this attachment portion 25 is provided with a first sawtooth profile 27.
  • the head piece inner part 22 coaxially interposed by the hose end portion 10, enclosed by a sleeve-shaped mounting portion 26 of the head piece outer part 23, the inner circumference is provided with a second sawtooth profile 28.
  • the individual teeth 32, 33 of the sawtooth profiles 27, 28 are annular, with the longitudinal axis 9 concentric course, whereby they are arranged in the direction of the longitudinal axis 9, that is axially, successively, resulting in the axial direction of a sawtooth-shaped profiling.
  • the sawtooth profiles 27, 28 are designed such that their flat tooth flanks 34 face the clamping gap opening 24 and thus the respective opposite other head piece.
  • the steep tooth flanks 35 point forwards to the front end face of the respective head piece 2, 3 opposite the contraction hose 4.
  • the two sawtooth profiles 27, 28 are arranged so that their teeth lie in pairs at the same axial height, so that in the axial direction, ie in the direction of the longitudinal axis 9, a multiplicity of tooth pairs results in each case a tooth 32 of the first sawtooth profile 27 and a tooth 33 of the second sawtooth profile 28 are radially opposite.
  • Several such radial "tooth planes" 36 are illustrated in phantom in FIG.
  • the head piece outer part 23 forms a compression sleeve 37 and is radially radially compressed with the hose end portion 10 enclosed by it, the hose end portion 10 being supported by the first fastening portion 25 of the head piece inner part 22 engaging from radially inward is. Due to this press connection, the teeth 32, 33 are pressed into the wall of the hose body 5, while the thereby displaced hose body material is received by the tooth spaces 38. In this way, the entire sawtooth profiled clamping gap 18 is filled by the material of the hose body 5. The resulting positive interlocking cause in conjunction with the strong radial pressure a firm grip of the hose end portion 10 and prevent its withdrawal even when very high tensile forces.
  • the compression sleeve 17 is supported against the attacking tensile forces axially on the head piece inner part 22.
  • the headpiece inner part 22 has a first abutment surface 42, axially upstream of the exemplary embodiment of the axial front side of the clamping gap 18, which is oriented axially forwards, ie points away from the contraction hose 4.
  • This first stop surface 42 has expediently annular shape and is located on a clamping gap 18 at the clamping gap opening 24 opposite front limiting, radially outwardly projecting annular collar 44 of the headpiece inner part 22.
  • the annular collar 44 thus projects radially beyond the first sawtooth profile 27 addition.
  • the two stop surfaces 42, 43 are not only the power transmission, but also the positioning of the compression sleeve 37 during its assembly.
  • the compression sleeve 37 Prior to assembly, the compression sleeve 37 is radially expanded according to FIG 3, that the radial distance between the defined by the tooth tips of the teeth 32, 33 first and second lateral surfaces of the two sawtooth profiles 27, 28 corresponds to the wall thickness of the contraction tube 4 or slightly is larger.
  • the inner diameter of the annular projection 45 is simultaneously slightly smaller than the outer diameter of the annular collar 44, so that sets a radial overlap.
  • the contraction tube 4 can be brought in a safe installation in the desired Aufsteckposition, the annular collar 44 acts as a Aufsteckanschlag for the contraction tube 4.
  • the contraction tube 4 is so far plugged from the back to the head piece inner part 22 until it with his End face 54 on the annular collar 44 comes to rest.
  • the annular gap 55 expands into that region which is located radially between the annular collar 44 and the section of the compression sleeve 37 surrounding it.
  • pressing the compression sleeve 37 reduces the radial height of the annular gap 55, as can be seen from a comparison of Figures 3 and 2 easily.
  • circumferential grooves 56 facilitate the fixation in the pressing tool not shown.
  • the first stop surface 42 forms in the embodiment, the edge of a designated as fixing groove 57 annular groove which is axially upstream of the annular collar 44 and the second edge is located at a further annular collar 58 which is located at a distance from the annular collar 44.
  • the outer diameter of the further annular collar 58 is less than that of the serving to define the Aufsteckposition annular collar 44 and is slightly smaller than the inner diameter of the still undeformed annular projection 45. In this way, the annular projection 45 in the slip-mounting over the other annular collar 58 slide away.
  • it dips into the fixing groove 57 so that the compression sleeve 37 is also prevented with certainty from a forward movement relative to the headpiece inner part 22.
  • the two lateral surfaces 46, 47 each have a conically tapering shape towards the front of the relevant head piece 2, 3.
  • the cone angle is relatively low and is preferably in the range of about 4 °. This results in a skew between a respective lateral surface 46, 47 and the longitudinal axis 9 of about 2 °.
  • the generatrices of the two sawtooth profiles 27, 28 which are defined by the two lateral surfaces 46, 47 and which can be seen in longitudinal section, expediently have a mutually parallel course. Also, the individual teeth 32, 33 are expediently identical to each other. In this way results in a constant surface pressure along the entire, of the sawtooth profiles 27, 28 covered clamping zone.
  • the contraction tube 4 has an outer diameter of 10, 20 or 40 mm in the deactivated base state, with a number of teeth of 12, 18 and 29 has proven to be expedient.
  • the tooth height is in particular the same for all these sizes.
  • the contraction tube 4 expediently has a slightly larger diameter in the region of the clamping gap opening 24 than in the disassembled state. This results in particular by the conically tapering in the Aufsteckraum of the contraction tube 4 nip course.
  • the contraction tube 4 experiences a slight bulge in the region of the clamping gap opening 24 and in the axially immediately adjoining rear end section 62 of the clamping gap 18.
  • the radial distance between the two lateral surfaces 46, 47 of the two sawtooth profiles 27, 28 in the fully assembled state of the compression sleeve 37 corresponds at least to the radial dimensions of the strand structure 6 embedded in the wall of the tubular body 5, and preferably somewhat is larger. Such a configuration can be seen in FIG. This ensures that the strand structure is not damaged by the teeth 32, 33 pressing into the tube body 5.
  • the strand structure 6 also maintains an at least substantially linear shape in the longitudinal direction of the contraction tube 4 in the fully assembled state of the respective head piece 2, 3. If the sawtooth profiles 27, 28 were offset axially from one another, in each case one tooth of the one sawtooth profile of the contraction hose could press into the radially opposite tooth space, which could result in a wave-shaped course of the strand structure 6, with the consequence of subsequent longitudinal expansions which would be detrimental to the strength. The special tooth arrangement counteracts this disadvantage.
