Definitions

  • the present invention relates to a device for driving an oscillating chute which can pivot around two orthogonal axes under the action of a pivoting control arm having the same degrees of freedom as the chute, comprising a transmission device for reproducing the movement of the control arm on the chute and vice-versa and a control mechanism articulated on an intermediate lever; articulated, in turn, on the end of the control arm, the control mechanism being designed to rotate the hinge constituted by the control arm and the intermediate lever around a vertical axis and to modify the angle d opening relative to this axis.
  • the control mechanism essentially comprises a drive rod capable of rotating around its longitudinal axis and being moved axially to open or close the angle of the hinge.
  • This drive rod comprises, for this purpose, a grooved section which slides longitudinally, under the action of a first motor, inside a rotary bush driven in rotation under the action of a second motor.
  • This known device has the disadvantage of being exposed to enormous mechanical stresses at the level of the grooves which make the rod integral in rotation with the outer drive bush. These stresses may hinder the sliding of the rod inside the bushing and cause premature wear. In addition, in order to be able to cope with these mechanical stresses, it is necessary to maintain and guide this rod at several levels which, in turn, causes the disadvantage of an increase in the height of the device d training and additional space.
  • the object of the present invention is to provide a new compact drive device for an oscillating chute which better withstands mechanical stresses, in particular to forces with horizontal components resulting from the weight of the oscillating chute.
  • the drive device is essentially characterized by a rotary cage carried, by means of a bearing, by the fixed wall of an external housing and provided with a toothed crown actuated by a first motor also fixed on the wall, by a control rod coaxial with said rotary cage, capable of sliding axially and connected, for this purpose, to a second motor, also fixed on said wall, by a crosspiece engaged via of a bearing on the end of the control rod so as to be axially integral, but free in rotation thereof and connected to the rotary cage so as to be integral with the rotation thereof, but free in the axial direction with respect to this cage, the intermediate lever being articulated on this crosspiece by its end opposite to that connected to the control arm.
  • the opposite ends of the cross member slide in grooves, U-shaped, provided at diametrically opposite locations on the inner face of the rotary cage. This sliding is preferably ensured by means of rectangular pads provided on the opposite ends of the crosspiece.
  • the end of the intermediate lever which is connected to the cross member is designed in the form of a stirrup, the two branches of which are crossed by the opposite ends of the cross member.
  • Figures 1 and 2 show vertical sections, in two perpendicular directions, of a drive device according to the invention
  • Figure 3 shows, in detail, a guide groove of the crosspiece.
  • FIG 1 there is a hinge 10 with a variable opening angle and which can rotate about a vertical axis O.
  • This hinge 10 consists of a control arm 12 pivoting around an axis X perpendicular to the plane of the sheet and an intermediate lever 14.
  • the control arm 12 is connected by means of an appropriate transmission mechanism 16 to a distribution chute not shown in the figures.
  • This transmission mechanism is preferably of the type proposed in European patent application EP-A-0062769, that is to say that it consists of a transmission bar 18, actuated by the arm pivoting control 12 and moving inside a sealed box 16 which is capable of pivoting about its longitudinal axis.
  • EP-A-0062769 European patent application EP-A-0062769
  • a rotary cage 20 coaxial with the axis O and supported by means of a bearing 22 on a shoulder 24 of a carcass 23 closed by a cover 26.
  • This rotary cage is provided with a ring gear 28 which is engaged with a drive pinion 30.
  • This drive pinion 30 is actuated by means of a first motor 34, for example electric, via a gearbox. 'gear 32. The action of this motor 34 causes, therefore, the rotation of the cage 20 around the central axis O.
  • a second electric or hydraulic motor 36 is also mounted on the cover 26. This motor 36 is intended to actuate a control rod 38 axially along the central axis O.
  • a crosspiece 40 consisting of a central body 42 and two pivots 44 and 46 diametrically opposite is mounted on the lower end of the rod 38 by means of one or more bearings 48, 50 so as to be free, in rotation with respect to this rod 38 and being integral with it as regards the vertical axial movement.
  • the two opposite pivots 44, 46 of the crosspiece 40 cooperate respectively with vertical guide grooves 52, 54 in the shape of a "U” provided at diametrically opposite locations on the inner face of the rotary cage 20.
  • the guiding of the pivots 44 and 46 in the grooves 52 and 54 can be improved by means of rectangular pads 56, 58 (see also Fig. 3) provided on the ends of the pivots 44 and 46.
  • the crosspiece 40 Under the action of the motor 36 the crosspiece 40 can be moved between the position shown in solid lines in Figure 2 and the position shown in phantom in the same figure and vice versa. This movement causes a modification of the opening angle of the hinge 10, that is to say a pivoting of the control arm 12 around the axis X.
  • This modification of the opening angle of the hinge 10 under the action of the motor 36 can, of course, be carried out independently and simultaneously with its rotation about the axis O as a result of the rotation of the cage 20 under the action of the motor 34.
  • the axis 60 of the hinge 10 is offset from the longitudinal axis of the control arm 12 so as not to remain blocked on the vertical axis 0 when the chute is in the vertical position as explained in the Luxembourg patent application LU-A-84225 (EP-A-0097859).
  • connection between the intermediate lever 14 and the cross-member 40 can be produced by constituting the upper end of this lever 14 in the form of a stirrup, the two branches 62, 64 of which are crossed by the pivots 44 and 46 and which serve as a pivot for this lever 14.
  • the connection between the control arm 12 and the pivot axis X can also be produced by a form of stirrup of the lower part of this arm 12, the two branches of which span the box 16.
  • This drive device is very compact, in particular with regard to the overall height since the height of the rotary cage can be reduced to the height necessary for the vertical sliding of the cross-member 40 and to the amplitude of the movement of the rod 38, compared to the state of the art, according to which the need to resist mechanical stresses, in particular to the lateral thrust components, imposes a much higher height of the drive device.
