Definitions

  • the present invention relates to an eccentric bolt for switch closures according to the preamble of claims 1 and 2.
  • the tongue clearance - also called tongue gap or tongue clearance - is set for a switch lock.
  • the tongue clearance between the floor rail (also called stock rail) and tongue rail has tolerances of about ⁇ 4 mm, because the floor rail can not be made more accurate as a rolled product.
  • the present invention is therefore an object of the invention to provide an eccentric, which can be clamped during assembly so that between eccentric and lock bearing no more play can occur and that impressem can be retrofitted clamped eccentric bolt.
  • the inventive eccentric bolt according to claim 2 differs from the eccentric bolt according to claim 1, characterized in that the eccentric pin is inserted into a cylinder-like part - this part is called a cone - and thus causes the cone directly a clamping of locking bearing with the eccentric pin.
  • Fig. 1 shows an eccentric bolt 1 for switch locks in a conventional design with two concentrically arranged cylinders 20, 20 'for inclusion in a lock bearing 11, not shown. Between the two cylinders 20, 20' is an eccentrically arranged cylinder 3. For the setting of the Tongue gap is a hexagon socket 21 is provided, can be rotated in the inserted with a Inbuss negotiatel the eccentric 1. By turning the Allen key, the tongue clearance can be adjusted. On the two-edge 18, the fixing disc 5 can be set. With a hex screw 7 (not shown) located in the bore 19, the fixing disc 5 is held in position without being pressed against the lock bearing 11.
  • Fig. 2a shows a preferred embodiment of an eccentric bolt 1 for switch locks with two concentrically arranged cylinders 20, 20 'for inclusion in a lock bearing 11.
  • the larger cylinder 20 has in its interior a conical shape, in the form-fitting a cone 2 can be inserted.
  • the cone 2 (both not shown) is pressed against the cylinder 20 so that it can be clamped against the closure bearing 11.
  • the eccentric pin 1 has a thread immediately after the hexagon socket, into which the hexagonal screw 7 engages.
  • a plurality of slots 22 are provided on the cylinder 20 in order to effect a better clamping or Aufdgurberry.
  • FIGS. 2b and 2c a respective front and rear view of the eccentric pin according to the illustration in FIG. 2a is shown.
  • FIG. 3 The cone 2 has - as explained above in relation to the prior art - a hexagon socket 21.
  • the cone In order to be able to make an adjustment with an Allen wrench, the cone must have a fixed coupling with the eccentric pin 1 even in the not yet pressed state.
  • an oval recess 23 is provided in the eccentric pin 1. This can be seen in detail in FIG. 2b. In this recess 23 engages positively an oval projection 24 of the cone 2 a. It would also be possible to provide the function of oval projection 24 and oval recess 23 reversed in another embodiment.
  • the cone 2 By tightening the hex screw 7, the cone 2 is pressed into the larger cylinder 20 of the eccentric pin 1.
  • a washer 9 is used for power transmission between the screw head and eccentric 1.
  • the conical shape between the cone 2 and the interior of the larger cylinder 20 is selected to be self-locking. Due to the tension of the slotted cylinder 20, the eccentric bolt 1 can now no longer rotate. For this reason, the fixing washer 5 may be pressed against the closure bearing 11.
  • the fixing disc 5 may therefore not be pressed because the screw 7 could be solved by a possible rotation of the eccentric pin and thus the fixing disc 5 no longer detects the position of the eccentric pin.
  • the fixing washer is no longer a safety-relevant part, but only forms a fallback if the tensioning of the eccentric bolt 1 should fail. This downgrading to a fallback level also applies to the dowel pin 10.
  • the tension of the eccentric pin 1 also causes a significant reduction in wear and helps to be able to reduce the maintenance and control costs.
  • a screw other than a hexagonal screw 7 may be provided, but for reasons of compatibility with the conventional eccentric pin and for reasons of reducing the variety of parts, the said hexagon screw 7 is preferably retained.
  • a sleeve 8 made of elastic material can be provided between the cylinder 3 and the closure pawl 2.
  • the preferred material is rubber. Since particularly high accelerations (vibrations) occur when driving on a switch by a train, a stroke limiting ring 14 is additionally installed, so that occurring loads are transmitted symmetrically to the closure pawl 12.
  • On the other side of the eccentrically arranged cylinder 3 is a ring 6 - as part of the whole eccentric pin 1, the Fig. 2c only indirectly refer to - provided, whose diameter is equal to the diameter of the Hubbegrenzungsringes 14. This is necessary because the bush 8 made of rubber does not rigidly transmit the occurring stroke or stroke displacement.
  • the intermediate layers 16 serve to adjust the Mouth depth at the lock bearing 11 at the distance between the tongue hole - tongue outside edge. They are intended to prevent the closure bearing 11 from rotating about the closure clip screw 15.
  • a cylinder-like part - also called a cone - is selected, into which a conically formed cylinder can be inserted by a tensioning or widening of the cone 2 '(not shown in the figures) to effect a firm connection with the closure bearing 11.
  • the better expandability or Aufdrückiana this cone 2 ' also slots.
