Definitions

  • the invention relates to a bearing for a circular, rotatable disc, in particular for the bearing disc a Drehsperrstrom for people passage control, are anchored to the locking elements, which successively by stepwise rotation of the bearing plate from a passage blocking position in a passage releasing Stel - Are movable.
  • CH-375 192 discloses a bearing for the turntable of a machine tool in which a total of three roller bearings are provided for complete support, namely an axial roller bearing which is arranged between the underside of the drive wheel fixedly connected to the driven pulley and the machine body is a radial roller bearing, which is inserted into the central bore of the drive wheel and has its inner seat on a socket or a shoulder of the machine body and another roller bearing, which presses in cooperation with a thrust washer and the thrust bearing against the central bearing.
  • a turnstile in which the rotatable, the locking arms carrying carrier disk is mounted by means of a central bearing on the fixed part of the turnstile.
  • DE 43 42 751 Al and DE 44 45 698 C2 show turnstiles or turnstile systems where the bearing of the barrier arms bearing bearing plate is rotatably supported by a central warehouse on the drive unit.
  • the object of the invention is to provide a bearing for a rotatable disc, which is less bulky and simple and inexpensive in construction while providing good guidance and support for the disc.
  • the disc is rotatably mounted on this carrier by means of a plurality of rollers which can be rolled on its circumference, but which are fixedly but rotatably mounted on a carrier.
  • Such storage is much less bulky than the known central warehouse. It builds much more space-saving especially in the axial direction, so you win on the back of the disc enough space for the installation of additional mechanisms. But it is very reliable and hardly subject to wear. Their structure is relatively straightforward and does not require the high precision, as it is indispensable in the known rolling bearings. The production is correspondingly less expensive.
  • a raceway groove is provided, in which engage the rollers and can roll it. This contributes to the functional safety of the storage.
  • the storage is preferably designed as a three-point bearing;
  • the best guidance and support of the rotatable disc can be achieved.
  • Certain tolerance variations can compensate themselves.
  • the disc is at its periphery by means of three rollers, which are fixed but rotatably mounted at an angular distance of 120 ° on the support, for example a support plate, mounted and guided. With three small bearings you get such a high stability.
  • FIG. 1 is a perspective view of a three-armed turnstile, in which the invention can be used, for example,
  • FIG. 2 shows the side view of the drive and locking unit of a turnstile according to FIG. 1 with the bearing according to the invention of the bearing disk, FIG.
  • FIG. 3 is a front view of the locking unit in the direction of arrow P in Fig. 2,
  • Fig. 4 shows a detail of the rear view of the locking unit of FIG. 3 and
  • FIG. 5 shows a side view of the blocking unit according to FIG. 3 and FIG. 4.
  • Fig. 1 shows an application example of the present invention, a known three-arm turnstile with a about a horizontal inclined by about 45 ° rotation axis locking unit 1, of which three locking elements 2 in the form of locking arms 2 to each other at an angle of Extend 120 °.
  • Fig. 2 shows the side view of the locking unit 1 together with its drive unit.
  • the locking unit 1 is mounted on a fixed support 3, here a support plate 3, and the locking arms 2 extend to each other at the same angle of 120 ° from a circular bearing plate 4, where they preferably with the help of spigot 5 are preferably held pivotally.
  • the bearing plate 4 is rotatably supported on its outer periphery on the support plate 3 by means of a plurality of bearing rollers 6.
  • it is a three-point bearing, ie at an angular distance of 120 ° each three bearing rollers 6 on the support plate 3 via bearing pin 7 stationary but rotatably mounted.
  • a raceway groove 8 is provided in the bearing disk 4, in which the rollers 6 can engage and roll therein when the bearing disk 4 is driven by a drive motor (not shown) via a drive shaft 9 (see FIG. 4) its central axis is rotated or twisted.
  • the storage described is simple and inexpensive in their design, it is less susceptible to interference and is subject to virtually no wear. It is very reliable and offers, especially in the preferred embodiment as a three-point bearing, optimal guidance and support for the rotating bearing plate 4, and it claimed in comparison to the known central warehouse significantly less space.

Abstract

L'invention concerne le montage d'une plaque rotative circulaire (4). Selon ladite invention, cette plaque est montée sur un support (3) au moyen de plusieurs, de préférence trois, galets de roulement (6) pouvant rouler sur le pourtour de ladite plaque, lesquels galets sont fixés à ce support de manière stationnaire mais rotative. Ce montage est simple et économique du point de vue de sa construction, mais très fiable et peu sensible à l'usure. Ce montage fournit un guidage et un support optimum, en particulier en version trois points.
