Definitions

  • the device is advantageously completed by a clamping system for continuous slides to pre-load the needles in a controlled manner.
  • the device according to the invention also comprises a fixed part 11 and a movable part 12.
  • the movement is carried out using two sets of technology similar to that used for the device in FIG. 1.
  • two sets of slides are used, that is to say two continuous slides placed parallel to one another in a relatively spaced apart position. Therefore, each continuous slide each comprises two convex rolling parts 13 fixed laterally on a rail 16 of the fixed part 11.
  • Each continuous slide also has a rolling sheath consisting of two concave rolling parts 14 placed laterally at the inside a cavity 17 of the moving part 12. Continuous rolling tracks are provided on the faces located opposite, in V, on each of these bearing parts.
  • Figure 3 shows, in a perspective view, the device according to the invention.
  • the rails 16 of the fixed part 11 have been shown protruding in length to show the rollers 18 mounted in sheaths of needle bearings.
  • the sheaths 19 are inclined in a V with the same inclination as the continuous tracks of bearings marked 20.
  • assemblies with protruding needle cages that is to say having a number of needles such that these needle cages have a greater length than the length of the movable part 12, in the direction of sliding. In this way, the mobile part 12 always rests, over its entire length and whatever its position, on a maximum number of needles 18.
