Definitions

  • European patent application No. 0 651 409 A1 describes a mechanism of this type.
  • all the teeth of the toothed pinion as well as the first tooth following, in the predetermined direction, the clearance generated by the discontinuity of the toothing of the large toothed wheel are configured so that their sides converge on a single edge.
  • the purpose of this measure is to prevent the gear wheels from blocking.
  • the friction of an edge of the toothed pinion on the side of attack of the first tooth following the release of the ferris wheel toothed generates more or less significant power losses due friction.
  • the present invention proposes to remedy all of these disadvantages and remove the risk of malfunctions of these known mechanisms offering an effective solution, simple to perform and little expensive and which can also be adapted by a transformation appropriate, to mechanisms of this type that are already in use.
  • the tooth of the toothing of said large gear wheel that follows the additional clearance has a shape similar to that of the retractable tooth.
  • said additional clearance extends over three gear pitches.
  • a mechanism with pawl 24 which comprises a pawl 25 actuated by an electromagnet 26 and a stop 27 mounted on one of the faces of the large toothed wheel 13, which cooperates with the pawl 25 to stop this wheel in the desired waiting position.
  • Figure 2 shows, on an enlarged scale, part of the Ferris wheel toothed 13 and the toothed pinion 19.
  • the teeth of the pinion 19 have a particular geometry which corresponds to a point size.
  • the flanks of these teeth join radially outward on an edge common and present, on the flank of attack, a developing and on the opposite flank, a plane starting from the edge and which is inclined with respect to a radial straight line passing through the middle of the corresponding tooth.
  • the large wheel 13 has a additional clearance 60 which is generated by a discontinuity complementary to the toothing 51 of this wheel.
  • This clearance extends over at least two gear steps. According to a preferred embodiment, this clearance extends over three gear steps.
  • the tooth 61 of the toothing of the large gear wheel, which follows said clearance complementary 60 has a shape similar to that of the retractable tooth 53.
  • the flanks join radially towards outside on a common ridge.
  • the opposite flank to the attack flank has an inclined plane in its upper part adjacent to the edge of the tooth.
  • the retractable tooth 53 is prominent over the others teeth 51 of the teeth of the large gear wheel, which has the advantage of reduce the likelihood that its tip will come into contact with the tip of a pinion tooth 19.
  • Figure 3C shows how the teeth of two wheels behave toothed.
  • the teeth 50a and 50b which follow the tooth 50 of the pinion 19 are located in the area of the additional clearance 60 during the entire movement joint of teeth 50 and 53.
