Definitions

  • the invention relates to an assembly consisting of a housing flange having at least one bolt arranged on the housing flange, from at least one component having a receptacle, which is arranged on the housing flange via the receptacle and the bolt, from a washer arranged on the bolt and from a nut screwed onto the bolt, by means of which the washer and the component can be prestressed against the housing flange, wherein the washer has a central recess having an inner diameter Di and a central axis M.
  • the bolt is usually designed as a stud, sitting in the housing flange.
  • the fastening element has a surface coming to bear against a workpiece surface, running at right angles to the central axis M, on which a circular arc extending, coaxial to the central axis M extending bead is provided.

  • a complementary form-fitting connection (grooving) between the nut and the bolt or the component in the circumferential direction is to be achieved indirectly via the lock washer.
  • the invention has for its object to simplify the fuse as part of a screw connection of an assembly.
  • the washer is non-positively in operative contact with the nut and a securing means is provided, via which the washer is secured against rotation in a circumferential direction U, and the securing means for the purpose of securing against rotation form-fitting against a bolt and / or a component can be applied and that the receptacle is designed such that the component can perform a relative movement to the bolt in a direction Rl due to a physical load, and the securing means can perform a relative movement to the component in a direction R2, wherein the direction R2 corresponds to the direction R1 or is equal to the direction R1 or parallel to the direction R1.
  • the recess should be designed such that the washer has a clearance in the radial direction relative to the bolt. This clearance between the bolt and the washer should not exceed 0.5 mm to 0.9 mm. Otherwise, the blocking effect of the securing means in the circumferential direction can be adversely affected.
  • the usual provided pairings or fits between bolt and washer are applicable. For a size M8 bolt, the clearance is usually 0.4mm because the washer has a 8.4mm diameter hole.
  • the nut can thus be tightened with smaller torque, so that a sliding behavior of the component is favored on the housing flange.
  • the washer is flat on its nut-facing side. There is nothing about this page that could justify a positive connection with the mother.
  • a positive connection between the washer and the nut can be provided, so that a Effective contact between the washer and the nut is created, which is non-positive and positive.
  • the diameter Di of the recess may be slightly larger than the outer diameter Da of the bolt.
  • the washer can be brought in the radial direction with some play against the bolt to the plant.
  • a play-free system is also possible and leads to a complete decoupling of the mother from the relative movements of the component.
  • this variant is associated with the assembly and disassembly with more effort.
  • the relevant here relative movement between the manifold flange and the housing flange is up to 5 mm and is due to the cyclic warming or cooling of the manifold flange or the manifold. Compared to these relative movements, other relative movements due to vibrations are negligible. They amount to at most 5% to 10% of the thermal relative movement.
  • the securing means is designed as a contact surface, which is integrally formed on the washer.
  • a normal vector N which can be formed on the abutment surface has a directional component in the circumferential direction U or in the direction tangential to the central axis M.
  • the contact surface ensures the formation of a positive connection between the washer and a component to be fastened, so that a relative movement between the washer and the component to be fastened in the circumferential direction U is prevented.
  • the contact surface as the end face of the washer or as Nose of the washer is formed.
  • a contact surface can be easily designed.
  • the contact surface can be formed by flattening, shearing, casting, folding or embossing the washer.
  • the contact surface can protrude in the axial direction to the central axis M via the upper or lower side of the washer to be applied against the component or against the nut.
  • the contact surface can thus be made via an integrally formed additional part to the washer in the form of a nose or a pin or in the form of a stamping or embossing of the annular disc.
  • At least one component has a stop surface corresponding to the contact surface of the washer, wherein the contact surface and the corresponding stop surface are displaceable in the direction R2 relative to one another. Due to the form fit between the washer and the component acting in the circumferential direction U, a rotation of the washer relative to the component is prevented in a simple manner. Thus, a possibly existing relative movement of the component to the stud in the circumferential direction U is also not transferred to the washer, so that such a relative movement can not be done between the nut and the bolt. The release of the nut is thus prevented.
  • the bolt has a stop surface corresponding to the contact surface of the washer. If it can be ensured that the bolt in the housing flange does not rotate or loosen, the securing means can also be formed against rotation of the washer by the bolt.
  • the bolt has a recess, such as a groove, which forms the stop surface and in which the washer comes with a corresponding contact surface for engagement in the circumferential direction U.

  • the further bolt which may in principle be any type of bolt or stop means, prevents movement of the washer in the circumferential direction, so that the nut is decoupled relative to the plane of the washer from a relative movement in the circumferential direction.
  • both components have a correspondingly formed receptacle, so that they can perform the relative movement in the direction Rl individually or together due to the physical load. With a bolt both components can be attached simultaneously. The relative movement of the respective component in the direction Rl can take place in the opposite direction or in the same direction. Two directions are the same if they are identical superimposed or aligned parallel to each other.
  • each of the bolts can be used to attach two or more components. Following the gist of the invention, it is only important that the relative movement of all components takes place in the same direction or takes place in parallel.
  • both components have a stop surface, wherein the contact surface of a washer abuts against one or both stop surfaces.
  • Each bolt has a securing element with a stop surface. Since in any case only a relative movement between the washer and the component is permitted, it is not relevant in the first place to which component the securing element rests.
  • the housing flange is a part of a cylinder head and the component is designed as Krümmerflansch.
  • Manifold flanges or manifolds are subject to large temperature fluctuations, which justify the sliding behavior of the manifold flange on the housing flange.
