Definitions

  • the present invention intends to remedy these drawbacks by proposing a robust and simple mechanical material eliminating the need for a fragile and costly complex control system, which can be easily controlled either manually, or automatically, or finally in a mixed manner.
  • each screw is coupled in rotation of one of the planetary wheel shafts of a mechanism consisting of two planetary gear trains, the planet carrier chassis of each of which is coupled to the output shaft of a first motor, so as to rotate the same amplitude and in the same direction, the other planetary wheel shaft of each of the planetary trains being coupled to its counterpart to rotate the same amplitude and in the opposite direction under the effect of a second drive motor from one of them.
  • the axes of rotation of the planetary wheels, of the planet carrier chassis and of the drive motors are parallel and parallel to the screws, the coupling of each of the chassis to the shaft of the first motor being carried out at by means of identical toothed wheels carried by each chassis and meshing with a pinion wedged on the shaft of the first motor, while the coupling of the two planetary shafts being achieved by meshing two identical toothed wheels wedged on each of them, their drive is ensured by the engagement of one of them with a pinion wedged on the shaft of the second motor.
  • Each planetary gear is carried by the screw to which it is coupled.
  • each wheel and pinion participating in these connections is of sufficient thickness to take into account the differences in altitude of the gear trains.
  • each of the motors used could be automatically controlled as a function of parameters taken from, in the case of a rolling mill, the sheet leaving this rolling mill, or to be controlled manually by an operator.
  • the main advantage of the device according to the invention lies in the total decoupling between the control of the displacement of the screw ends parallel to themselves and the control in opposite direction symmetrical with respect to a fixed point of these ends. The result is an extremely simple servo device and much safer than those implemented so far.
  • Each of the screws 1 a , 2 a is coupled to one of the planetary wheels 7 a , 8 a of a planetary gear train 7 and 8, the other planetary wheel of which is referenced 7 b , 8 b and whose planet gears 7 c , 7 d , 8 c , 8 d are carried by a planet carrier frame 7 e , 8 e .
  • Planetary trains 7 and 8 have the distinction of having their concentric planetary wheel axes. And one of the axes being constituted by screws 1 a, 2 to another, coupled to the wheels 7 b, 8 b is constituted by a sleeve 9, 10 surrounding the screws.
  • each chassis 7 e 8 e of differential module is equipped with an identical toothed wheel 11, 12, which cooperates directly with a pinion 13 output from a geared motor group 14.
  • each planetary sleeve 9, 10 is equipped with an identical toothed wheel 15,16 and meshing with the other, one of these wheels, here 16, being driven by the pinion 17 of a second motor 18 or motorcycle group -reducer.
  • the rotation of the pinion 13 is controlled in the appropriate direction by feeding of the motor unit 14. This rotation generates the rotation of the two planet carriers 7 e and 8 e in the same direction. Since the group 18 is not powered, the pinion 17 is stationary, as are the wheels 15 and 16 and the corresponding planet wheels 7b , 8b . Under these conditions the rotation of the chassis 7 e , 8 e causes the rotation of the planet wheels 7 a , 8 a therefore the screwing (or unscrewing) of the screws 1 a , 2 a in the corresponding nuts, and this at the same speed therefore with the same amplitude as shown by a simple calculation.
  • the roller 5, in the case of application of FIG. 2, is therefore moved parallel to itself, relative to the roller 6. It is understood that a simple control of the position of the roller 5 relative to the roller 6 can be obtained from a sensor of the thickness of the laminated product that is to be obtained.
  • the motor 14 can moreover be controlled by an operator who visually monitors the product from the rolling mill and controls the pinch corrections as a function of the quality of the product which he appreciates; for its part, the motor 14 is controlled by a gauge which compares the actual thickness of the product with a set value.
  • the pinions 13 and 17 will have a sufficient tooth length E2, E4 (in the direction axial) to always be in engagement with the wheels, axially movable due to the two possible movements of the screws (together or in opposite directions).
  • the motors can also be supported by a frame which moves with point 0 of the roller 5.
  • the invention finds an interesting application in the field of mechanical construction, in particular rolling mill trains.
