Definitions
- the present invention relates generally to machines of cables of the kind comprising a frame in two parts, namely a part fixed and a part stabilized with respect to the fixed part, at least one coil rotatably mounted on the stabilized part of the frame, and a rotor which, rotatably mounted on the fixed part of the frame, circulates between it and the stabilized part.
- Only one coil can be provided, if it is a coil receptor.
- the rotor has a lyre, on which travel the wires in the process of stranding, and with which it is usually associated, in diametrically opposite position, a counter-lyre, for its balancing.
- the present invention generally relates to a layout allowing, in a simple and light way, a vertical layout rotor, without risk of vibration and resonance.
- the fixed part of its frame includes, on the one hand, a C-shaped upright, which extends substantially in a vertical plane, and which, at its ends, carries, aligned vertically with each other, two bearings at the favor of which the rotor is rotatably mounted, and, on the other hand, a base, forming ballast, which carries the upright, and below which there is a relatively flexible elastic support.
- the machine frame of cables according to the invention and, in particular, the fixed part of this frame, can advantageously be reduced, for the benefit of the cost of the whole.
- this cable machine advantageously has a reduced footprint.
- the elastic support provided according to the invention is for example divided into a plurality of studs of elastic material of the type of those known under the trade designation "SILENTBLOC".
- the elastic support in the constitution of which these studs in elastic material participate is particularly flexible, being preferably capable of a crushing included in 15 mm and 20 mm under 750 kg.
- the fixed part of the frame of the cabling according to the invention is capable of significant travel by vertical, under the effects of a simple horizontal thrust.
- the cable machine 10 comprises, overall, in a manner known per se, a frame 11 in two parts, namely a part 11A fixed and a part 11B stabilized with respect to the fixed part 11A, at least one coil 12 rotatably mounted on the stabilized part 11B of the frame 11, and a rotor 13, which, rotatably mounted on the fixed part 11A of the frame 11, circulates between the latter and the stabilized part 11B.
- the fixed part 11A of the frame 11 comprises, with part, a C-shaped upright 14 which extends substantially along a plane vertical, and which, at its ends, carries, vertically aligned with each other, along an axis A, as shown in broken lines in FIG. 5, two bearings 15, 16, one upper, the other lower, thanks to which the rotor 13 is rotatably mounted, and, on the other hand, a base 18, forming ballast, which carries the amount 14, and below which intervenes, according to provisions described in more detail later, an elastic support 19, relatively flexible.
- the stabilized part 11B of the frame 11, commonly called stirrup also includes an upright 21, in form of C, which extends along substantially the same vertical plane as the upright 14 of the fixed part 11A, inside this upright 14, FIG. 2, and which, at its ends, is engaged, for its maintenance, with tree ends not visible in the figures.
- the upright 14 of the fixed part 11A comprises, in a cross, in its middle zone, two arms 22, which generally extend along a sector circular, and, in correspondence, the upright 21 of the stabilized part 11B also has a cross in its middle zone, two arms 23, which generally extend along a concentric circular sector of the previous, with opposite two by two of the arms 22 of the fixed part 11A aux arm 23 of the stabilized part 11B, magnetic weights 24.
- the base 18 of the fixed part 11A of the frame 11 must form ballast, its mass is a significant fraction of the total mass of the entire frame 11.
- the mass of this base 18 is at least equal to the sixth of this total mass.
- it is between one sixth and one third of it.
- the base 18 has, in plan, a general configuration in H, with two legs 25, Figures 1, 2, 3 and 5, and a cross member 26, FIG. 3.
- the legs 25 are slightly curved, with their concavity facing outwards.
- the base 18 is generally massive.
- the two legs 25 are symmetrical to each other with respect to the vertical plane along which the amount 14.
- the elastic support 19 present according to the invention under the base 18 is divided into a plurality of pads of elastic material 27 arranged at a distance from each other.
- five pads of elastic material 27 are planned.
- All the pads of elastic material 27 are identical to each other. other.
- each of them has, overall, in a manner known per se, a tubular, spindle shape, with a surface exterior having, at the ends, each respectively, of a section median 28 cylindrical, two tapered end sections 29 of concavities facing one another.
- such an elastic material pad 27 has, at its upper part, a threaded nut 30, which, arranged axially, intervenes at the like an insert, and, at its lower part, a sole 31, which intervenes transversely, and of which it is secured, for example by screws 32, FIG. 4.
- Elastic pads of this type are sold, for example under the commercial designation "EVIDGOM” by the company PAULSTRA HUTCHINSON.
- each pad in material elastic 27 is sandwiched between the base 18 and an individual shoe 33, rigid, by means of which the attachment to the ground can be ensured all.
- the individual shoe 33 is in the form of a box of square cross section or rectangular, which, seen from the side, has a trapezoidal outline.
- the sole 31 of the pad of corresponding elastic material 27 is secured to the upper wall 34 of this individual shoe 33 by screws 35 however that this individual shoe 33 carries on the ground 36 by its lower wall 37.
- the elastic support 19 which jointly forms the pads made of elastic material 27 is preferably capable of being crushed between 15 mm and 20 mm under 750 kg.
- each of these pads of elastic material 27 is individually capable of crushing between 15 mm and 20 mm under 150 kg.
- stop means are provided for limit the travel of the fixed part 11A of the frame 11 relative to the vertical.
- these stop means comprise, for at least one of the pads of elastic material 27, and, preferably, for each of these, a tie rod 38, the head 39 of which takes support on the base 18, and which, crossing, successively, vertically, this base 18, the pad of elastic material 27 concerned, while engaging screwing, by the way, with the threaded nut 30 thereof, and the upper wall 34 of the individual shoe 33 underlying, door, beyond this upper wall 34, and therefore, beyond the stud of elastic material 27, at a distance from this wall upper 34, a retaining shoulder 40.
- this shoulder retaining 40 is formed by a nut 41, which is screwed onto the tie rod 38 and which is fixed thereon by a lock nut 42.
- the stabilized part 11A of the frame 11 carries, side by side, two coils 12, of horizontal axis.
- These coils 12 are emitting coils.
- the cable machine 10 does not fall under, for the rest, of the present invention, it will not be described in more detail here, in particular with regard to the rotary mounting of the coils 12 and in that which concerns the mechanical tension compensator 43 associated with each of these.
- rotor 13 As regards the rotor 13, it will suffice to indicate that, in a known manner in itself, it comprises, in positions diametrically opposite one another, a lyre 44 and a counter lyre 45 joined at their ends by nuts 46, and that it turns around the coils 12.
- the present invention is moreover not limited to the form of embodiment described and shown, but includes any variant.
