Definitions

  • the present invention relates to positive type cam mechanics which in the textile industry are intended to ensure the control of heald frames of weaving looms, and it relates more particularly to the double roller levers with which the mechanics of this kind.
  • each roller 8 is mounted idly on an axis 11 attached against one of the lateral faces of the lever 6, which does not penetrate between the cams 9.
  • These cams are thus likely to be arranged side by side on their shaft, practically in contact with each other, by reducing the axial size of the assembly they form; on the other hand, the travel of the rollers (distance c) is very small.
  • the invention essentially intends to remedy, which aims at producing a lever with double rollers which makes it possible to obtain a very large travel of the rollers (value c) while allowing the cams to be mounted on the drive shaft at the shortest distance possible (value ej.
  • each of the rollers comprises a rotating ring which cooperates with rolling bodies, these two assemblies being held axially with reduced clearance in both directions by one or the other of two flanges on a fixed axis which is made eccentrically integral with the lever in question and which has a total width substantially equal to that of the aforementioned ring, so that the latter can penetrate deeply between the cams accompanied by the rolling bodies and part of the fixed axis.
  • the rolling bodies are advantageously provided in the form of balls, rollers or needles which constitute an intermediate bearing mounted between the axis or fixed support and the rotating ring, thereby ensuring that a lever-roller assembly with very high long service life and very good performance, wear due to specific pressure and overheating subsequent to running speeds being reduced to a very large extent.
  • reference 6 designates, as in the case of FIG. 4, the edge of the lever which is intended to support one of the two rollers.
  • This edge 6 comprises a thinned lateral flange 6a which is integral with an eccentric extension intended to constitute a fixed axis or support 12 for a roller bearing 13 on which the inner edge of a ring 14 is engaged, it being observed that the axis 12 and the ring 14 have substantially the same thickness.
  • the axial retention of the ring 14 is provided by the bearing 13 which is itself retained axially in both directions by two annular flanges 12a projecting from the periphery of the fixed axis 12. This retention is thus carried out under conditions optimal since it is exercised in the direct vicinity of the contact of the ring 14 with the corresponding cam 9. This avoids any risk of lag.
  • the fixed axis or eccentric support 12 is capable of penetrating between the double cams 9 so that its ring 14 can come into contact with the elementary disc 9a or 9b of said cams, thereby allowing a very large stroke and a favorable actuation of the lever 6 and of the heald frame 1 with which the latter is associated.
  • This strong penetration of the ring 14 between the double cams 9 does not in any way modify the axial size of the assembly of these cams on their common drive shaft 10, owing to the fact that the total thickness of the ring 14 and of the flange 6a can be left at a value at most equal to the thickness of one of said cams.
  • the fixed axis or support 12 is capable of being mounted eccentrically between two terminal flanges of the lever 6, in a manner similar to that according to FIG. 3.
  • Fig. 7 illustrates such an embodiment and it can be seen that the fixed axis or support 12 is here fixed, for example by means of through rivets such as 15, between two thinned flanges 6a of the lever 6, this fixing being operated eccentrically.
  • the bearing 13 interposed between this axis 12 and the rotating ring 14 is retained axially in both directions by annular flanges or stops 16 integral with said axis 12.
  • the flanges or retaining stops 16 are fixed laterally against the ring 14, the axial holding effect being identical.
