  • the grinding wheel is in contact with the rail 12 by its front planar face and its advance travel, compensating for its wear and defining its cutting depth, takes place in an arc under the effect of the jack 5.
  • This direction d advance is substantially parallel to the generator g of the grinding wheel in the vicinity of its point of contact with the rail 12, that is to say that it forms with the axis of rotation of the grinding wheel 1 an angle equal to the half the angle at the apex formed by the tangents to the generatrices of the grinding wheel 1.
  • the area of congestion of the grinding wheel, in the vicinity of the rail, defined by its front face and its generatrix g is always the same as it is let the grinding wheel advance. Thanks to this arrangement, this grinding wheel can never come into contact with obstacles, counter-rail, signaling boxes, etc., located along the track near the rail to be reprofiled.
  • the peripheral surface of the grinding wheel has a generator in an arc of a circle and the advance movement of the grinding wheel takes place along a radius R which is substantially identical.
  • the peripheral surface of the grinding wheel may have curvilinear, non-circular generators, in this case the means for advancing the grinding wheel must be designed to move the latter substantially parallel to its generator in the vicinity of the point of contact with the rail.

  • the drive motor 3 is rigidly fixed to a gusset 4 secured to the chamber 5 of a double-acting cylinder whose piston 6 is secured to a guide column 7 passing right through the chamber 5.
  • This column guide 7 is secured to a support 8 fixed with bolts 9 to a carriage 10 of a railway vehicle. Due to the lights 11 1 of the support 8 it can be fixed on the carriage 10 according to several orientations so as to vary the position of the grinding wheel 1 relative to the rail 12 depending on the part of the head of the rail that is desired reprofile.
  • the guide column 7 is provided with conduits 13, 14 opening on one side and the other of the piston 6 in the chamber 5 of the hydraulic or pneumatic cylinder.
  • the angle rp between the axis of the jack causing the grinding wheel 1 to move in advance, displacement defining the depth of cut and compensating for l 'wear of the grinding wheel, and the axis of rotation of the grinding wheel 1 is of the order of 30 °. This angle can be chosen within very wide limits depending on the portion of the rail to be reprofiled.
  • this angle rp is substantially equal to half the angle at the apex ⁇ of the conical grinding wheel 1, so that the direction of advance of the grinding wheel 1 towards the rail 12 is substantially parallel to the external generator. of the grinding wheel in the vicinity of its contact point with the rail.
  • the grinding device is positioned relative to the track in such a way that a counter rail, a signaling box or any other obstacle located along the track is outside the zone in which the grinding wheel moves during the advance of the vehicle along the track.
  • the axis of rotation of the grinding wheel 1 forms an angle rp with the direction of advance of this grinding wheel defined by the axis of the jack.
  • the front working surface of the grinding wheel 1 is of frustoconical shape and intersects the peripheral surface of the grinding wheel, also frustoconical, approximately at right angles.
  • This arrangement is particularly advantageous for reprofiling the upper running surface of the rail 12. It is seen that thanks to this arrangement this upper running surface of the rail can be reprofiled even at level crossings where the rail 12 is practically buried in the roadway.
  • the angle (p included between the axis of rotation of the grinding wheel 1 and the direction of advance thereof, that is to say the axis of the jack is substantially equal to half the angle at the apex ⁇ of the tapered grinding wheel 1 and the advancement of the grinding wheel takes place substantially parallel to its generator in the vicinity of its point of contact with the rail.
  • the support 8 can in this embodiment be mounted on the carriage as illustrated for example in Figure 1. Thus, it is possible to tilt the grinding wheel relative to the rail to be reprofiled according to the portion of the rolling table to be reprofiled.
  • Figure 4 illustrates an embodiment of the grinding device used for reprofiling the lateral face of the rail head.
  • the conical wheel 1 is rotated by the motor 3 along a horizontal axis.
  • the gusset 4 secured to the motor 3 slides on two solid bars 15 of the support 8.
  • a lug of the gusset 4 is articulated on the rod 16 of a double-acting cylinder 17 controlling the advance travel of the grinding wheel 1.
  • the direction of advance of the grinding wheel 1, parallel to the rods 15, forms an angle ⁇ with the axis of rotation of the grinding wheel 1 and is substantially parallel to the generator of the grinding wheel in the vicinity of its point of contact with the rail.

  • the connecting rod 33 extends vertically like the line connecting the pivot points 30 and 31.
  • the end of the lever 28 pivoted on the carriage comprises an ear 35 articulated on the casing of a double-acting cylinder 36 whose rod 37, integral with the piston, is pivoted on an ear 38 which has the end of the pivoted lever 29 on the connecting rod 33.
  • the axis of rotation of the grinding wheels 26 is not confused with the direction of advance of these grinding wheels, controlled by the connecting rod 33, but forms an angle q J with respect to this direction.
  • This angle q J can be adjusted by modifying the angular position of each working unit relative to the support 27.
  • the entire parallelogram device described above can be pivoted around axes 39 in order to be able to orient the advance movement of the grinding wheels as a function of the area of the rail profile to be ground.
