Definitions

  • the present invention relates to a Exzentereinstellelement and an eccentric disc and a method for producing such Exzentereinstellelementes.
  • this Exzentereinstellelemente included a bolt-like screw with a directly under the head firmly mounted eccentric and an external thread, which was interrupted by a profiling, so that the second eccentric could be attached to this profiling with a defined angular position of the eccentricity. Then the entire Exzentereinstellelement was secured or fixed by screwing a nut on the external thread.
  • Corresponding adjusting elements are known for example from FR 2720 845 Al.
  • this object is achieved by a Exzentereinstellelement with a pin with at least one free end with a profiled section and an end adjacent thereto external thread with a smaller outer diameter, in which on the profiled section an eccentric is attached, by a on the External thread screwed nut is secured by a hollow cylindrical or tubular spacer is mounted between eccentric and nut.
  • a further preferred solution is that the spacer itself is internally provided with a matching profile to the profile of the profiled section and is pressed into a recess in the eccentric disc.
  • the spacer which alone carries the profile is pressed into the respective desired angle in the eccentric, glued or welded ,
  • a particularly high flexibility with respect to the angle ratios to be realized between profile in the spacer and eccentricity of the eccentric disc is obtained when the spacer is formed on the outside round, and the recess in the eccentric disc is also circular.
  • the spacer outside as a polygon, preferably as a hexagon or hexagon, form, and to make the recess in the eccentric corresponding to the outer shape of the spacer.
  • the spacer is preferably glued to the eccentric disc, caulked or welded.
  • the spacer inside with a profile and pressed into a recess in the eccentric disc, glue or weld, if one wishes to achieve optimum flexibility in the assignment between eccentricity of the disc and angular position of the profile.
  • the spacer is formed on the outside round, and the recess in the eccentric disc is also circular.
  • the spacer outside as a polygon, preferably as a hexagon or hexagon, and form the recess in the eccentric corresponding to the Form outer shape of the spacer.
  • the spacer can be inserted into the eccentric and caulked there, welded or glued.
  • Figure 1 shows an inventive Exzentereinstellelement, wherein an eccentric disc with integrally formed spacer is used
  • Figure 2 shows another inventive Exzentereinstellelement with a spacer inserted between eccentric disc and nut loose

  • the profiling 20 At the end of the shaft 18 is followed by the profiling 20 an external thread 22 with a smaller outer diameter.
  • Invention also provided an eccentric screw with fully profiled shaft, in which case the first eccentric disc 16 is not made in one piece with the head 14, or is pressed or caulked on the shaft 18, but also attached to the profile.
  • the present invention is applicable to an eccentric rod, in which instead of the head 14 and the first eccentric disc 16 is a mirror image of the profiling shown here and the external thread shown here, a similar construction provided at the other end of the rod.
  • Corresponding eccentric rods are known, for example, from DE 20 2007 013 473 U1, to which reference is made as regards the description of an eccentric rod as such.
  • An eccentric screw with over the entire shaft continuous profiling and two plugged eccentric discs is known for example from DE 20 2007 006 410 Ul.
  • a simple second eccentric disc attached to the profiling 20 in contrast to the above-mentioned prior art, not a simple second eccentric disc attached to the profiling 20. Instead, a special second eccentric 24 is provided here, in a known manner a bore or punched out, which is provided with a counter-profile to the profile 20. According to the invention, a tubular, so hollow cylindrical projection 26 is integrally attached to the eccentric disc 24 here. This may have the same inner diameter as the bore or cutout in the eccentric disc 24. Optionally, it may also be provided with the same profiling, but this is not mandatory for the function of the present invention.
  • a special nut with a hollow cylindrical projection for screwing the second eccentric disc 24 is not required here.
  • the approach 26 extends namely according to the invention into the region of the external thread 22, and in this way the second eccentric disc 24 can be secured by screwing a commercially available standard nut 28. It is thus possible for the first time to use a commercially available standard nut 28 for securing or screwing the eccentric disk 24 in the case of an eccentric adjusting element with profiling spatially separated from the external thread. According to the invention, the nut 28 no longer has to be able to partially overlap not only the external thread 22 but also the profiled section 20.

  • This spacer 126 only has to have a sufficiently large inner diameter. With a profiling it does not need to be provided. The production of such a spacer 126 is therefore extremely simple.
  • FIG. 3 shows yet another embodiment of the present invention. Again, the already known from the prior art eccentric screw 12 is used, as described in detail in Figure 1. Like reference numerals also refer to like components herein.

  • the spacer element 226 has an outer contour that is round or polygonal.
  • the disc 224 has a punched hole or bore with a corresponding inner diameter and a matching inner contour.
  • the portion of the spacer 226 which is inserted into the disc 224 may be used to prevent insertion errors, e.g. Too deep or oblique insertion, to prevent in the area that should not be inserted into the disc 224, have a larger diameter and / or a different outer contour, so that a stopper step 228 is formed, on which the disc 224 after assembly of washer 224 and spacer 226 is applied.

  • the outer contour of the spacer 226 may also be round in certain other applications.
