Abstract

A motor which does not require an energy input comprises frames (1, 2) between which is placed a slanted disc (3) fitted with permanent magnets (9) and mounted on a shaft (5) which is excentric in relation to a driving shaft (6), but the free end of which is brought back into the axis of the driving shaft (6). The internal faces of the frames (1, 2) carry permanent magnets (10), and a magnetic mask (12), attached to a flywheel (11) connected to the excentric shaft (5) and the driving shaft (6), surrounds the rotating disc (3) on two opposite 90 DEG sectors to short-circuit two magnetic zones of attraction. <IMAGE>

Description

SPECIFICATION Rotary force generator The invention concerns a rotary force generating machine.

We know a mechanico-pneumatic device which transforms a constant unidirectional energy into a constant kinetic energy, in which the source of unidirectional energy is constituted by a permanent magnet inserted between two poles. This assembly, which works together with a flat annular part for closing the magnetic field, is fixed on a base plate of the frame of the appliance provided with regulators for the air space, these regulators being placed radially in pairs 1200 from one another, one of the pairs being aligned with the primary axes of an oscillating plate carrying a crankshaft inclined at 15"C from the vertical axis passing through the centre of the oscillating plate. This device must be put on charge so that the fluid in a determined number of pneumatic chambers is compressed, whereas the other chambers are in depression.

These pressures and depressions cause thrusts to the oscillating plate and impart a rotating movement to the crankshaft.

This device is complicated. It needs a rotary distributor and chambers whose tightness must be practically perfect.

The aim of this invention is to provide a rotary generating machine of simple constuction which needs no energy contribution, which is silent and which produces no atmospheric pollution from exhaust gases.

The annexed drawings show, by way of example, one embodiment of the object of the invention.

Figure 1 is a plane view, with partical cut-away of its upper frame.

Figure2 is a section along line ll-ll of Figure 1,the rotary disc and the magnetic mask not being sections.

Figure 3 is a section along line Ill-Ill of Figure 1 and Figure 4 is a partially cut and sectioned view to show the disposition of the permanent magnets on the rotary disc and on the lower frame.

The machine shown comprises a lower frame 1 and an upperframe2forming a covering-. Arotary disc 3 is mounted in a housing between frames 1 and 2, disc 3 being mounted via a ball bearing run 4 on a rotating shaft 5 which is excentric in relation to a driving shaft 6 guided in ball bearings 7 and provided with a pulley 8. The rotary disc 3, which carries mobile permanent magnets 9 placed on its two faces and constituting polar magnetic fields, is attracted by a device similar to fixed permanent magnets 10, which are attached to the lower frame 1 and the upper frame 2.This device exercises an upward force on the front part and a downward force on the back part of the rotating disc 3, at the opposing points where the air space is most reduced between the fixed permanent magnets 10 and the mobile permanent magnets 9. The resultant is a torsion effect which causes the flywheel 11 on the excentric shaft 5 to rotate, this flywheel being connected to the driving shaft 6. The flywheel supports and carries with it a magnetic mask 12 which surrounds the rotating disc 3 on two sectors 90" opposed (see Figure 1), its function being to short-circuit the two magnetic zones of attraction which are set back from the perpendicular of the excentric shaft 5 and thereby to define a magnetic zone of attraction solely on the front part of this perpendicular.The front point of the perpendicular of the excentric shaft 5 is defined by a downwards inclination and thereby determines the direction of rotation of the machine.

The lower 1 and upper 2 frames, which support the fixed permanent magnets 10, present inclined faces whose angle of inclination is identical to that of the faces of the rotating disc 3, so that the air gap should constantly be in parallel to the opposite points above and below, these being the points at which the mobile permanent magnets 9 of the rotating disc 3 are exactly opposite the fixed permanent magnets 10 in the lower 1 and upper 2 frames, and closest to them.

The lower part of the magnetic mask 12 is fixed between a clamp ring 13 and a ball bearing run 14 in a housing of the lower frame 1. The point of the excentric shaft is brought into the axis of the machine (axis of shaft 6) and is supported against a bearing housing 15 composed of a diamond in a support 16 screwed into the lower frame 1.

The parts supporting the fixed permanent magnets 10 and the mobile permanent magnets 9 are in a magnetic metal. Shafts 5 and 6, the flywheel 11 and the clamp ring 13 are preferably in steel and the magnetic mask 12 is made of a metal with a maximum paramagnetic coefficient, combined with a similar mechanical rigidity. To stablise the machine, a balancing mass (not shown) is mounted opposite the excentric point of shaft 5 and fixed to the flywheel 11.

The fixed permanent magnets 10 are placed in such a manner that, when the mobile permanent magnets 9 arrive at the spot where the air gap is most reduced, they are exactly face to face (see Figure 1). The mobile permanent magnets 9 on one of the faces of the rotating disc 3 are all polarised in the same manner and placed in the same direction.

They are in magnetic opposition to those on the opposite face of this disc. The fixed permanent magnets 10 are also all polarised in the same manner and placed in the same direction. However, they are opposite in polarity to the mobile permanent magnets 9.

Thanks to the layout described we obtain a continuous rotary movement from a unidirectional source of magnetic energy, since the rotary disc 3 on the excentric shaft 5 is attracted downwards at the front and upwards at the back of the perpendicular of the excentric point of shaft 5 which supports it, causing a torsion of the latter which is centred at its base and ex-centre above in relation to the driving shaft 6 (axis of the machine). This torsion effect causes the rotation of the magnetic mask 11 supported by the driving shaft 6. The magnetic mask 11 short-circuits a zone of the rotating disc 3 and obliges this disc to be magnetically attracted by the fixed permanent magnets 10 in the direction of rotation of the machine. This magnetic mask, which is fixed to the flywheel 11 situated in the axis of the machine, is not subject to any force opposing that of the rotary disc 3 and therefore does not hinder the progress of that disc. The mechanical force taken up by the pulley 8 is a function of the angle of excentricity of the excentric shaft 5 and the air gap between the mobile permanent magnets 9 and the fixed permanent magnets 10. The variation of these two factors can serve as a regular or interruptor of force.
