Definitions

  • the present invention relates to a machine intended for digging trenches in the ground by milling.
  • each drum consists of two half-drums supported on either side of a flat metallic core of small thickness which is arranged vertically, perpendicular to the axis of the drum.
  • the machine sinks due to its weight as the terrain disintegrates under the action of the tools placed on the drums, it is essential to work in rocky terrain, that the central core is as thin as possible, because the tools cannot disintegrate the ground located below the central core.
  • the drums are subjected during their work to very high forces and significant vibrations
  • the motors most often hydraulic, whose frame is subject to the central core and whose axis supports the half drums, are subjected to such constraints that they have a relatively short lifespan.
  • the present invention relates to a new device for mounting the motors on such vehicles which has the advantage of giving both greater rigidity to the central core and of preventing the motors from being themselves subjected to stresses and vibrations exerted on the drums.
  • the subject of the present invention is a machine of the aforementioned type, characterized in that the central core which supports the two half-drums is constituted by a vertical plate traversed by a hollow tubular sleeve with horizontal axis, coaxial with the drum, said sleeve receiving inside of it the motor for driving the half-drums, motor whose casing is locked in rotation relative to the sleeve, a flange being secured at each end of the sleeve to support the bearings of the corresponding half-drums which are driven from the motor axis.
  • the driving of the half-drums is ensured by a grooved shaft which engages both in grooves situated inside the axis of the rotor of the motor and in grooved orifices of two plates located on either side of the motor and integral in rotation each with a half-drum.
  • the splines of the shaft are engaged in the corresponding splines of the hollow axis of the motor and in the splines of the plates with sufficient clearance to ensure that the only force transmissible by the motor to the plates is constituted by the torque which drives the half-drums in rotation.
  • a train of The reduction gear can be arranged in place of the plates between the ends of the splined shaft and the half-drums.
  • a hollow splined shaft inside which there is a compensation chamber with variable volume (for example made of elastomer), which makes it possible to ensure pressure balancing on either side of the seals.
  • Figure 1 the lower part of the body 1 of the machine which is provided with two drums 2 arranged at the same level and rotating around two parallel axes in the direction of the arrows.
  • Each of the drums 2 is constituted by two half-drums arranged on either side of a core 3 secured to the lower part of the machine.
  • the drums 2 are provided with tools 4, the periphery of which is shown diagrammatically in FIG. 1 by circles in phantom.
  • the inlet orifice 5 of a suction pump (not shown) which rises to the ground surface the debris of ground detached by the tools 4 during the rotation of drums.
  • a pipe 6 which passes through the core 3 and which supplies the motor with the energy it needs, this energy which can advantageously be constituted by a hydraulic fluid but which can also be constituted for example by electric energy.
  • the core 3 is provided with a cylindrical sleeve 7 whose horizontal axis 8 is perpendicular to the plane of the core 3.
  • the inside diameter of the sleeve 7 corresponds substantially to the outside diameter of the motor 9 which is schematically shown in the drawing.
  • a flange 10 is secured by screws (schematically shown in phantom by their axes) on each of the ends of the sleeve 7. Screws 11 schematically shown make the motor 9 of the flanges 10 integral.
  • these screws 11 essentially have the function of immobilizing the motor 9 in rotation relative to the socket 7, the flanges 10 being firmly fixed on the latter by the screws of which it has been previously spoken.
  • the hollow axis 12 of the motor 9 has internally grooves 13 schematically shown which correspond to the grooves of the shaft 14 which drives the half-drums 2.
  • the half-drums 2 are mounted on the flanges 10 by bearings 15 (for example roller bearings), a grooved plate 16 which engages on grooves 17 formed at the ends of the shaft 14 ensuring the integral in rotation of the half-drums 2 with the shaft 14 and consequently with the axis 12 of the motor.
  • bearings 15 for example roller bearings
  • a grooved plate 16 which engages on grooves 17 formed at the ends of the shaft 14 ensuring the integral in rotation of the half-drums 2 with the shaft 14 and consequently with the axis 12 of the motor.
  • each plate 16 is connected to the crown 18 of the half-drum 2 also by grooves 19 which, thanks to their play, avoid any force other than the drive torque being transmitted between the half-drum 2, the shaft 14 and the motor 9.
  • seals 20 which prevent debris from the action of the tools 4 mounted on the drums 2 from infiltrating to the bearings 15.
  • the sleeve 7 which is arranged transversely on the core 3, has the effect of substantially stiffening the latter which is thus better able to withstand the large constraints of all kinds which are inherent in this type of machine.
  • the shaft 14 is a hollow shaft containing inside a chamber 21 of variable volume which makes it possible, in the manner known per se, to achieve pressure balancing on the part and on the other side of the seals 20 which are thus protected against deformations of their linings.
  • the device has the same structure, except that the half-drums 2 are rotated by a train of pinions 22 rotating on axes 23, integral with the flanges 10, these pinions 22 meshing, on the one hand on toothing 19 produced at each end of the shaft 14, and on the other hand on toothing 19 produced on a crown 18 secured to each half-drum 2.
  • FIG. 4 schematically shows a perspective view of the core 3 provided with its socket 7.
  • the axis of the sleeve 7 is horizontal and perpendicular to the core 3 which comprises at the upper part the plate 5 which allows it to be securely fixed to the lower part of the machine.
