Definitions

  • the invention relates to a method for improving the work through an ECCENTRIC BALANCE with VARIABLE PITCH, applicable to a mechanism, as a lifting element using minimum energy for cranes or as the piston pumping at an oil extraction wellhead and consists of a process that produces an improvement in mechanical work by means of a new construction method of a classic balance, namely the addition of a short rod (AO) under initial scale's long rod (AH) so that the short rod will be supported on the fulcrum in the centre of balance at one end (O) while the other end will be bonded with one end of the initial long rod (AH).
  • AO short rod
  • AH initial scale's long rod
  • the height (AH) increase with an additional distance ( ⁇ ') and by this extension of the active force arm (OH), with additional length, from the initial open angle, it creates a unbalancing in this mechanism with an moment of force equal with distance gain ( ⁇ ') and as smaller as angle alfa becomes, as big as the HH' become and the resistive force will be added with it, creating by intentional unbalance, an ascension moment on the opposite end (A) proportional with the additional distance added to the total height of the triangle dynamically created, compared to the initial triangle, when free weight-carrying ends of the long rods, were in an angle position wide open (square) and when the eccentric balance was in equilibrium.
  • the levers are simple mechanisms consisting of a rigid body, usually in the form of the rod, in which acts three forces (the fulcrum, active force and resistive force) and that can create a balance of forces, perpendicular to the reference system, i.e. the Earth's surface.
  • Levers can be arranged by Grades, depending on the position of the fulcrum relative to lever's Rod.
  • Grade 1 namely balance or scales, with the rod positioned on fulcrum, half the distance between the point of active force application and the point of resistive force application on the balance's rod.
  • the mechanism acts exactly the same forces described originally from classical balance, and weights are added to a long rod when it is in mechanical equilibrium, with the difference that the fulcrum of balance becomes eccentric and the long rod is no longer supported directly on its initial fulcrum (O) but on its projection ( ⁇ ') in a vertical plane in relation to the reference grid as shown in Figure 2.
  • the free ends of the rods that carries half the weight of the original active force should it approach and closing in, mirroring each other synchronously, one another, towards and outwards the main axis of the mechanism, which is represented in part by the short Rod, generating an angle that varies according to the distance between the weight- carrying ends of the long rods.
  • the initial active force and the resilient force, respectively their equivalent weights, attached to the free ends of the long rods, remains constant in this mechanism.
  • This process of achieving mechanical advantage has the benefit that we can adjust the mechanical equilibrium in the above described mechanism, opening up the two long rods with weight-carrying ends, at a convenient angle, which can be a square angle, and with the rod's ends caring weights, spaced at equal distances relative to the main axis of the mechanism, so that the mechanism is in mechanical equilibrium relative to the reference grid that is the Earth's surface, so that resistive force, i.e.
  • the mechanism described above must have the two long rods open at an angle wide enough, and a square angle is recommended as ideal for this modality of implementation, and the length of the long rods shall be selected from the start of construction of the device, so that the height of the triangle described theoretically, must have equal lengths related to fulcrum, for the projection of the active Force when long rods are open at the square angle and the projection of resistive Force towards fulcrum, are equal.
  • Long rods remain roughly parallel to the surface of the Earth, which is considered as reference system. Additional length to the height of the triangle described above, is gained by synchronously closing/opening of the long rods free ends, and can be calculated mathematically, for each size of the angle of opening of the rods.
  • the height of this initial triangle is calculated trigonometrically, as being equal to the numeric value of the cosine of the half angle formed by the of rods and described above, multiplied by the length of one of the two long rods regarded as sides, because the height in an isosceles triangle is also bisector and divides the triangle in two equivalent rectangular triangles AHB and AHC as shown in Figure 3. In this way we can find out the value of the scalar initial triangle's Height, whereas only one of the above equivalent triangles, by well known mathematical formula:
  • the additional length mathematically depends on the size of the angle formed by the synchronous rotation of the long rods and by applying additional length relative to the point of initial application, in order to make the translation of the application of additional distance relative to the initial projection of point (H), using less energy for mechanical rotation-translation in this case, and substantially less for pushing weights on a horizontal plane through direct horizontal friction, because through the screw principle, rotating around a shaft by rolling mode, the friction is much smaller than sliding weights along the force's arm on a horizontal plane:
  • (F) is the scalar size of the force acting on the free ends of the rods projection, calculating the constant weight at the rod's end, where (r) is the scalar length of a rods, and (sin a) is derived from the angle of the long rods for each of the alpha angle sizes, which is a result of moving of free weight-caring ends of long rods.

Abstract

L'invention concerne un procédé d'équilibre excentré à angle variable destiné à améliorer les performances d'un mécanisme de levage, et qui produit un travail mécanique par l'intermédiaire d'un équilibre classique modifié pour obtenir un équilibre excentré. De cette manière, on crée un équilibre dans lequel un angle variable excentré est formé par l'ouverture ou la fermeture des extrémités libres de crémaillères portantes, qui, à leur tour, lorsqu'une action d'ouverture/fermeture se produit, les rendent similaires à un triangle théorique dont la hauteur est la projection d'axe, le point d'appui d'équilibre se situant au milieu. Grâce à ce procédé, outre le fait que lors de la translation des extrémités libres des crémaillères portantes, le frottement dans l'axe horizontal est considérablement réduit en raison du principe de la vis issu de la physique classique, et compte tenu du fait que les crémaillères, intégrées dans une crémaillère courte par l'intermédiaire de roulements à billes radiaux, sont actionnées en vue d'une rotation synchrone par un moteur bidirectionnel pour être déplacées d'une dent sur chaque crémaillère par une denture de pignon, la consommation d'énergie est fortement réduite.
