Definitions

  • the present invention relates to the mechanisms for controlling the reciprocating movement of the claw frames of an armor mechanism.
  • the improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of connections between the mechanical control shaft and the connecting rods associated with claw frames which require only limited lubrication.
  • crank arms offset angularly and whose crank pins are located at a certain distance from the geometric axis of the tree, two short connecting rods and two long connecting rods being articulated to said crank pins and respectively to the lower and upper claw frames.
  • the articulation of the connecting rods on the crankpins can be made by means of sealed ball bearings which do not require lubrication and can therefore work in the open air.
  • the single figure of the drawing is a schematic side view of one of the ends of the control shaft of an armor mechanism comprising a mechanism for controlling the reciprocating movement of the claw frames in accordance with invention.
  • the frame 1 shows a frame 1 of an armor mechanism comprising two claw frames.
  • the lower claw frame has been referenced 2 and the reference 3 has been assigned to the upper claw frame.
  • crank arms 5, 6, 7 and 8 of the same length have been set each comprising at their free end a crank pin 5 a , 6 a , 7 a , 8 a .
  • a leveled crowd is obtained.
  • an oblique crowd is sought and under these conditions the arms 5, 6, 7 and 8 are of different lengths, adapted to the desired average obliquities.
  • crank arms 5 - 8 are suitably angularly offset so that the crank pins located on the same side, that is to say those 5 a and 6 a, are associated with one of the ends of short connecting rods 9, 10 whose other ends are articulated to the lower claw frame 2.
  • the crank pins 7 a and 8 a opposite those 5 a , 6 a are articulated at one of the ends of the long connecting rods 11, 12 whose ends opposite are articulated to the upper claw frame 3.
  • the articulations of the four connecting rods to the two frames are effected by means of an axis mounted rotating in ball bearings associated with the corresponding ends of said connecting rods.
  • the axes of the connecting rods 9, 10 are referenced 13, 14 while those of the connecting rods 11, 12 are referenced 15 and 16.
  • the two claw frames 2, 3 each have on their two opposite ends two series of holes 20 a , 20 b respectively 30 a , 30 b distributed over a circumference whose radius is equal to the length of the connecting rods 9, 10 respectively 11, 12. It is observed that the two series of holes of each frame of claws are arranged on either side of the median axis X, X 'of the frame considered.
  • the axes 13, 14, respectively 15, 16 are engaged in holes of the two claw frames, chosen so that the latter move back and forth parallel one with the other for the realization of a leveled crowd. If one wishes to produce an oblique crowd, it suffices to change the position of the axes in the series of holes of the claw frames to make them take the chosen oblique position allowing the realization of the desired oblique crowd.
  • Both the crank arms of the crank arms 5 - 8 and the pins 13 - 16 are articulated to the connecting rods 9 - 12 by means of sealed ball bearings or the like, so that the assembly considered is simple, economical and easy to maintain , therefore inexpensive.
  • the adjustments which exist on the known mechanisms for controlling the claw frames at the level of the cams and the follower rollers, and which are complex to carry out, are quite simply transferred according to the present invention to the claw frames from which they are particularly easy to perform.
