Definitions

  • these low power vibrators are particularly suitable for driving in clay soils for which it is necessary to produce vibrations having an amplitude whose minimum value is of the order of a few millimeters, and this, depending on the elasticity of this type of soil.
  • a more particular subject of the invention is therefore the design and production of a vibrator that can, at different speeds, mobilize all of the available power of the vibrator, so as to overcome the drawbacks mentioned above and to be able to have some sort of multiple devices in one (high frequency at small time and medium frequency at large time).
  • the invention can involve n engine body, so as to be able to obtain a multiplicity of frequencies each of which is determined by the ratio between the flow rate of the pump and the displacement used which is that of one of the bodies or equal to the sum of the displacements of several bodies.
  • the vibrator according to the invention may also comprise a device making it possible to vary the moment of the vibrator by generating a phase shift respectively affecting the rotation of the weights of the two cells.
  • the vibrator comprises two trains of eccentric weights 1, 2 rotatably mounted by means of shafts 3, 3 '- 4, 4' parallel to a transverse axis, and the ends of which are s 'engage in bearings 5, 6 carried by two parallel flanges 7, 8 constituting the two lateral sides of a housing.
  • each of the weights 1, 2 is associated a pinion 10, 10 '- 11, 11' dimensioned so that the pinions associated with the same train of weights 1, 2 mesh together.
  • two train weights 1, 2 are shown, each comprising at least one pair of feeder / pinion assemblies 1 - 10, 1 '- 10', 2 - 11, 2 '- 11' shown in solid lines , the assembly shown partially in broken lines indicating the mode of implantation of another couple.
  • the pinions 10 and 11 of the two counterweight trains 1, 2 further mesh with two respective coaxial pinions 12, 13 axially parallel to the transverse axis and coupled to one another, by means of a device for transmission 14 with phase shift controlled by a pressurized fluid.
  • the piston 22 carries at its cylindrical surface one or more helical grooves 28 with relatively large pitch. In this or these grooves 28 engage one or more lugs 29 integral with the inner surface of the sleeve.
  • the profile of the pins is drawn as a function of the compromise sought between the reduction of friction and the overall mechanical resistance which depends on the torque to be obtained.
  • a spring 25 is not essential. Indeed, due to the torque naturally generated by the effect due to the action of the weights 1, 2 (resistance to sinking), these tend to be disposed naturally in phase. However, to allow automatic phase shift return, a residual phase shift should be maintained.
  • the distributor D1 is in position 1, while the distributor D2 is in position 2, so that the total flow D of the pump P passes through the motor M1, the motor M2 rotating in freewheel.
  • the frequency F1 of the vibrator is a function of the ratio of this flow rate and the displacement of the motor M1.
  • the two distributors D1 and D2 are in position 1 and are therefore crossed by two fractions complementary to the flow D of the pump P.
  • the frequency F2 of the vibrator is then a function of the ratio between the flow rate D and the sum of the displacement of the motors M1 and M2.
  • an M2 engine with a displacement of about half that of the main engine makes it possible to have two operating speeds, for example 1500 and 1000 rpm, or even 2250 rpm ( high frequency) and 1500 rpm (medium frequency) with the same time.
  • the vibrator could involve n motors coming to be connected in the manner of the motor M n shown in broken lines in FIGS. 4 and 5.
