Definitions
- Pneumatic motor with propulsion disc by reaction Pneumatic motor with propulsion disc by reaction.
- the aim sought after according to the invention was to produce an engine 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 of revolutions. per minute.
- Another object sought after according to the invention was to design a pneumatic motor of simple manufacture, quick assembly, inexpensive, of low weight and size avoiding all connecting and fixing parts, while guaranteeing a high operating reliability.
- the pneumatic motor is remarkable in that it consists of a rotating shaft mounted on bearings driven in rotation under the effect of at least one jet of pressurized air and high flow leaving at at least one orifice or exhaust mouth formed radially on at least one propellant disc secured to the axis of the engine, the said orifice opening onto the outside diameter of the propellant disc disposed in an exhaust cage.
- the propellant disc is arranged with a central bore for its mounting on the axis and comprises on one of its sides a recess constituting a chamber for receiving pressurized fluid; on the periphery of said disc and in its thickness being provided one or more exhaust ducts originating at one end opening into said receiving chamber and opening at their other end constituting a reactive duct over all or part of the length of the disc propellant and its outer periphery; side plates closing said disc laterally.
- the engine finds a particularly advantageous application for deburring and milling turbines.
- FIG. 1 is a longitudinal sectional view of the pneumatic motor according to the invention.
- FIG. 2 is a large-scale perspective view of the propellant disk of the engine, in particular illustrating the fluid receiving chamber.
- FIG. 3 is a front view of the propellant disc.
- FIG. 4 is a side view along line A-A of Figure 3.
- 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 leaving 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) secured to 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 overflowing at 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 exhaust cage.
- the shape and profile of the exhaust and reactant duct (s) are produced in the most appropriate 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 seal laterally 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 lateral 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 grille (8) is attached and fixed to the external or internal periphery of the sleeve part of the cage for receiving 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 it 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 discharged through 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 duct produced on the engine axis, all the reception chambers produced on each disc will be at the same pressure, as will the exhaust ducts.
- 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.
