Ie. no thread extending over the entire length of the inner lumen is formed on the inner lumen of the parent component. Instead, only a portion of the inner lumen of the parent member is threaded.
  • This section of the mother component is axially spaced from the second component when the second component is seated on the second component, wherein the extended portion of the inner lumen is arranged between the second component and the threaded portion, in which the through-bolt is spaced from the inner wall of the parent component.
  • the nut member allows the use of through-bolts with greater clamping length to compensate for bias losses, wherein the desired clamping length determines the axial dimension of the adjacent to the second component extended portion of the nut member.
  • the parent component of the screw according to the invention combines the functions of the previously required expansion sleeve and nut in one part, whereby the production of the screw compared to the previously known screw this kind of unification in particular unfortunate assembly conditions to a considerable extent becomes facht, since only two loose parts, namely the through-bolt and the parent component for the preparation of the screw must be handled.

  • the second component facing the end of the nut member may completely pass through the recess formed on the second component or engage only in a portion of the recess.

  • the insertion depth of the mother component into the recess of the second component is limited by the shoulder thus formed.
  • the depth of engagement of the female component in the recess of the second component can advantageously be limited by the fact that Mother component for this purpose stop means are provided.
  • These stop means are expediently arranged or formed on the parent component in such a way that they abut on the edge of the recess of the second component in the case of the parent component engaging in the recess of the second component.
  • the end of the parent component facing the second component is formed by a shoulder having a non-rotationally symmetrical cross section, the cross section of the recess formed on the second component corresponding to the cross section of the shoulder.
  • the recess formed on the second component but only in the region in which engages the end of the parent member, must have a non-rotationally symmetrical cross-section and in the remaining area only the implementation of the through-bolt must allow.
  • the recess formed on the second component has over its entire length a cross-section corresponding to the shoulder of the nut component.
  • the fixation of the mother component can be particularly advantageous if the first component or the remaining components to be connected to the second component do not yet rest on the second component and the outside of the second component remote from these components is still readily accessible for the arrangement of the parent component.
  • the cross-sectional shape of the recess and the cross-sectional shape of the heel formed on the parent component are basically arbitrary, as long as they deviate from a circular shape.
  • the shoulder of the parent component preferably has a rectangular outer contour and, corresponding to this, the recess formed on the second component has a rectangular inner contour.
  • stop means preferably provided for limiting the penetration depth of the nut component into the recess of the second component is likewise basically arbitrary.
  • any protrusion aligned on the outside of the nut component can be used transversely to the connecting direction of the components to be connected.
  • This projection may be an integral part of the parent component or may be formed by a separate part attached to the parent component.
  • the parent component has a radially outwardly projecting annular shoulder adjoining the end of the shoulder facing away from the second component, which extends at least partially in the radial direction over the cross-sectional profile of the shoulder.
  • a bearing bush for the push-through screw is arranged in the recess formed on the first component for passing through the through-bolt, said bushing being connected to a through-hole screwed off from the second component. turned outer edge of the recess rests positively.
  • the recess formed on the first component has a cross section which is greater than the cross section of the shank of the through-bolt and corresponds to the outer cross section of the bearing sleeve for the push-through, while at one end of the bearing sleeve preferably a radially projecting annular shoulder is formed, which the outer edge of the Auslang is the first component to the plant.
  • the bearing bush is arranged completely in the recess formed on the first component.
  • a radial extension may be formed, which advantageously accommodates the ring shoulder formed on the bearing bush such that one end face of the the bearing sleeve formed annular shoulder with the outside of the first component is aligned.
  • the bearing bush expediently has an extension for receiving the screw head at its front end in the insertion direction of the push-through screw.
  • the parent component at its end facing the second component has a shoulder with non-rotationally symmetrical cross section which engages against rotation of the nut member in a correspondingly formed recess of the second component
  • the head of the through-bolt and preferably also on the bearing bush formed extension rotationally symmetrical may have a cylinder head and the expansion formed on the bearing bush. tion for receiving the screw head for this purpose be correspondingly cylindrical.
  • the screw according to the invention is particularly suitable for the connection of components that are exposed to changing operating forces or temperature changes. Such operating conditions occur, for example, during the deployment of military submarines.
  • the invention therefore also relates to a submarine in which at least two components are connected to a screw connection as described above.
  • Submarines usually have a pressure body and the pressure body at least partially outside surrounding outer skin.
  • the outer skin is usually formed by covering parts of a fiber composite material, which are fastened to straps which are arranged on the outside of the pressure hull.
  • FIG. 1 shows very greatly simplified and at different scales: a screw of two adjacent 'components in a plan view, 2 shows the screw connection according to FIG. 1 in a section along the section line II - II in FIG. 1, FIG.

  • only a rectangular section in the region of the screw connection is shown in simplified form of the outer skin part or component 2 and the carrier or component 4.
  • the two components 2 and 4 lie flat against each other.
  • the component 2 has a recess 6 in the form of a through hole, which extends in the connecting direction of the components 2 and 4 through the component 2 therethrough.
  • the recess 6 is essentially cylindrical, but it has a conical enlargement 8 adjoining the outside of the component 2 facing away from the component 4.
  • a recess 10 is formed on the component 4 and extends through the component 4 in the direction of connection of the components 2 and 4.
