Definitions

  • the present invention relates to a bearing that has hydraulic fluid by the support base and rotates on a horizontal axis. It is intended to support large rotating masses fixed to the shaft, with the entire weight of the shaft being distributed through the fluid by the bearing's inner circumference, eliminating the need for metal rollers, thus giving friction as well as negligible wear. It can be produced in different sizes, it is an innovative and very simple system, providing great efficiency and low maintenance cost.
  • the invention called “Hydraulic Rail System” of the same inventor, whose mechanism allows large mass to be supported by hydraulic fluid, providing linear movement through rail. Also of the same inventor and following the mechanism line of the first example is the invention called “Vertical Shaft Hydraulic Bearing”, the purpose of which is also intended to support large rotating masses fixed to a vertical axis.
  • the present invention in addition to other uses, is directed to horizontal axis wind turbines whose conventional bearing system still generates high maintenance costs in addition to decreased performance due to friction.
  • the industrial sector is the technical area for which the present invention is intended.
  • Figure 1 in a front section, shows the mechanism inside.
  • the shaft in a socket whose shape is square.
  • the socket find four parts that support it.
  • Each of the four pieces is solid and has hatches in the drawing. All have a cylindrical shape near the shaft fitting and widen on its opposite, concave, T-shaped shape. These four pieces support the shaft and fit each other into four cubic reservoirs of hydraulic fluid.
  • the cylindrical part of the "type" part leaks into the bearing center opening, meeting the shaft socket.
  • the bottom T-type part is above the hydraulic fluid supporting the shaft.
  • the upper part which fits into the cubic reservoir, locks into the bearing body where it no longer presses the shaft.
  • the two side pieces do not support any weight.
  • the full weight of the bearing inner body presses on the base of the outer circumference that involves the inner body. Only the shaft is being supported by hydraulic fluid.
  • the inner body of the bearing must rotate a millimeter away from the outer circumference to fit perfectly inside and without exerting any pressure.
  • a conventional bearing would be coupled laterally to the inferno body. In this way the entire internal body, which does not have significant mass, would fit millimetrically inside the drums, would rotate and be supported on common bearings while the mass-bearing shaft would rotate and be supported by the hydraulic fluid distributed in all reservoirs.
  • Figure 2 demonstrates the other embodiment.
  • another eight smaller concave reservoirs will also be made in the bearing inner body. Unlike the others, they will not be linked together.
  • small ducts located at the center, perpendicular to the shaft will connect and distribute fluid from the larger reservoirs to the three or four smaller ones that alternately pass over the hydraulic ducts as the mechanism is turned.
  • the pressure generated on all fluid by the weight of the shaft will cause the bearing inner body to float above the fluid as well as the shaft.
  • the calculation of the surfaces and volumes of the smaller concave reservoirs should be accurate as it should be proportional the weight of the inner body of the mechanism and the pressure of the hydraulic fluid.

Abstract

L'invention concerne un mécanisme dont le fonctionnement est basé sur un fluide hydraulique, permettant de supprimer la nécessité d'utiliser des galets métalliques pour supporter les axes soumis à une masse importante et tournant sur un axe horizontal, l'usure et le frottement devenant ainsi insignifiants.
