Definitions

  • the problem which the invention proposes to solve is to produce a motor capable of working at very high speed and finding multiple applications in particular for tools requiring cutting speeds requiring rotational speeds of the order of several tens of thousands. revolutions per minute.
  • a pneumatic motor of the type of those consisting, in known manner, of a rotating shaft mounted on bearings and driven in rotation under the effect of at least one jet of air exiting from at least one orifice, or exhaust outlet, formed radially at any angle on at least one propellant disc secured to the axis of the engine, the air jet being injected at said axis, the propellant disc being arranged with a bore central for its mounting on the axis and comprising, on one of its sides, a recess constituting a chamber for receiving the air jet, in the form of a fluid under pressure and high flow rate, said air jet being injected by means of a groove formed on the axis, said chamber being in communication with one or more exhaust ducts formed in the thickness of the disc and one end of which opens out from
  • the receiving chamber is cylindrical, the exhaust duct or ducts are formed throughout the thickness of the disc while flanges close the disc and the exhaust duct or ducts laterally.
  • the flanges are attached and glued to the lateral faces of the disc and to the axis of the engine, the propellant disc (s) also being glued to the axis.
  • the propellant disc is mounted in an exhaust cage having a cylindrical sleeve and extending on one side with a wall forming a bottom mounted in a fixed position on the bearings; an exhaust grille being attached and fixed to the outer or inner periphery of said sleeve.
  • the engine finds a particularly advantageous application for deburring and grinding turbines.
  • the pneumatic motor consists of a rotating shaft (1) at very high speed mounted on two bearings (2) and driven in rotation under the effect of at least one jet of air exiting under pressure and high flow leaving at least one orifice or exhaust outlet formed radially at any angle on at least one propellant disc (3) integral with the axis of the engine, said orifice opening onto the outside diameter of said propellant disc.
  • the pneumatic motor comprises one or more cages for receiving one or more propulsion discs driven in rotation by at least one injection of a pressurized fluid, liquid or gaseous.
  • the engine comprises a propellant disc (3) arranged with a central bore (3.1) for mounting on the axis of the engine.
  • the disc comprises on one of its sides a recess (3.2) constituting a chamber for receiving the pressurized fluid.
  • one or more exhaust ducts (4) originating at their end (4.1) while being in communication with the receiving chamber, and projecting through their other end (4.2) by constituting a reactive conduit over all or part of the width of the propellant disc and on the outer periphery thereof by projecting the fluid into the inner chamber of the cage exhaust.
  • the shape and profile of the exhaust and reactant duct (s) are produced in the most suitable manner for guiding and orienting the fluid, and for practical implementation.
  • the propellant disc is mounted and fixed on the axis by any appropriate means and in particular by gluing.
  • On either side of the propellant disk are disposed front and rear flanges (5-6), intended to laterally seal the disk receiving chamber and the fluid exhaust duct or ducts while leaving the reactive duct free.
  • These flanges made of any suitable material, of desired thickness, are attached and fixed to the side faces of the disc and advantageously by gluing. They are also fixed by gluing by their internal bore (5.1-6.1) on the axis of the motor.
  • the assembly thus formed is rotatably mounted in the exhaust cage (7).
  • This is in the form of a cylindrical sleeve with a bottom wall (7.1) mounted in a fixed position on the bearings (2).
  • An exhaust grid (8) is attached and fixed to the external or internal periphery of the sleeve part of the receiving cage of the propellant disc.
  • This grid is arranged in its central part with an opening for the introduction of a fluid injection nozzle (9) mounted at the end of a fluid supply pipe.
  • the axis of the nozzle is opposite the end of the motor axis.
  • the end of the latter is conical and partially engages in said nozzle to avoid loss of the fluid.
  • To guide and introduce the fluid into the receiving chamber of the propellant disc there is provided on the axis a groove (10) constituting the fluid injection conduit.
  • the operation of the air motor should be specified.
  • the user sends a pressurized fluid through the injection nozzle which penetrates via the injection duct produced on the axis of the engine into the receiving chamber of the propellant disc.
  • the fluid is then evacuated by the exhaust duct (s) arranged radially on the propellant disc.
  • the latter is then rotated by driving the axis of the motor with which it is associated.
  • the fluid is projected onto the internal periphery of the exhaust cage, then it is discharged through the openings or vents of the exhaust grille.
  • such an engine rotates at a speed which can be regulated by the intensity of projection of the fluid in order to reliably reach speeds between 25,000 and 150,000 revolutions / minute.
  • the pneumatic motor can comprise several propulsion discs mounted on the shaft giving it multiple possibilities of torque. Via the injection pipe produced on the engine axis, all the reception chambers produced on each disc will be at the same pressure as will the exhaust pipes.
  • the exhaust duct is extended to form the reactive duct, the latter being produced in the form of a hole, a slot, a keyway-like groove, of cross section suitable for the desired engine torque. .
  • the pneumatic motor according to the invention finds numerous applications.
  • this engine is particularly advantageous for deburring and grinding turbines, or engraving or drilling.
