DESCRIPTION

TRANSMISSION DEVICE FOR ENERGY GENERATION FROM ALTERNATING MOTION

The present invention relates to a transmission device for the generation of energy from reciprocating motion of the type specified in the preamble to the first claim.

In particular, the present invention relates to a transmission device for the generation of energy from reciprocating motion capable of allowing, for example, the conversion of a wave motion into electrical energy.

Various generators of energy, in particular of electric energy, from wave motion are currently known.

For example, there are generators based on the water jump of sea water during wave motion, systems based on Archimedes' principle, Pelamis generators, buoy generators with cable tied to the seabed, ?surface attenuator? which exploit their internal deformation due to wave motion, oscillating water column generators, which exploit the variation in volume caused by wave motion in a semi-enclosed space and many other systems.

Also known are the oscillating wave motion converters, known by the acronym OWSC (Oscillating Wave Surge Converter).

Such devices typically have a portion connected to the seabed or to a fixed structure and collect energy from the relative movement of the wave motion with respect to the fixed structure. They therefore include systems that can be moved by waves such as floats, fins or membranes.

A typical OWSC system ? consisting of a rectangular plate hinged, along one of the four main sides, on the seabed or on a fixed structure.

The said plate ? moved alternatively clockwise and counterclockwise, around the said hinge, by the wave motion. An alternator? connected to the plate and receives energy from said rotation.

The prior art described includes some important drawbacks.

In particular, said wave energy generators are very bulky and difficult to install. In fact, they are generally made up of very bulky structures which must be installed on the seabed.

Furthermore, wave energy generators can be harmful to the natural marine environment and to aquatic transport. In fact, their volume and their movement can constitute a major obstacle to them.

An additional drawback? given by the fact that wave energy generators do not have a high efficiency.

In this situation, the technical task underlying the present invention? devising a transmission device for the generation of energy from reciprocating motion capable of substantially obviating at least part of the aforementioned drawbacks.

In the context of this technical task ? an important object of the invention is to obtain a transmission device for the generation of energy from reciprocating motion which is simple to install and which is economical.

Another important purpose of the invention ? create a transmission device for the generation of energy from reciprocating motion that is not harmful or hindering the natural marine environment and boats.

Not the last purpose of the invention? that of obtaining a transmission device for the generation of energy from reciprocating motion which has a high efficiency. The specified technical task and aims are achieved by a transmission device for the generation of energy from reciprocating motion as claimed in the attached claim 1.

Preferred technical solutions are highlighted in the dependent claims.

The measurements and data reported in this text are to be considered, unless otherwise indicated, as performed in an ICAO International Standard Atmosphere (ISO 2533:1975).

With reference to the Figures, the transmission device for the generation of energy from reciprocating motion according to the invention ? globally indicated with the numeral 1. The device 1 can be substantially used within an energy generation plant 100.

The 100 plant, overall, ? preferably configured to convert the motion of an external stress vector into energy, preferably of the electric type. Therefore, the alternating motion of the external vector is preferably acquired in the form of mechanical energy and then subsequently returned in the form of electrical energy.

The system 100 therefore comprises the device 1 and at least one electric generator 101.

The Electric Generator 101 ? any electrical device capable of producing electrical energy from mechanical energy. In particular, the electric generator 101 ? at least capable of converting a rotary motion, for example of a shaft, into electrical energy. Therefore, the electric generator 101 ? connected to device 1 as better specified below.

In addition, the 101 plant can? also include a hydraulic apparatus 102.

The hydraulic apparatus 102 can? basically include a plurality? of ducts and hydraulic elements suitable for controlling the flow and outflow of a fluid, for example water, inside.

Therefore, the hydraulic apparatus 102 can? include a distribution circuit 103.

The distribution circuit 103 can? be a closed or open hydraulic circuit, operatively connected to the device 1 to move at least part of the latter in relation to the flow of the fluid carrier inside the distribution circuit 103.

Is the connection between distribution circuit 103 and device 1 ? also better specified later.

Briefly, the device 1 comprises at least a structure 2, a main transmission unit 10 and a thrust element 3.

Structure 2? preferably integral with a soil. Therefore, it can be a structure fixed to the ground, or even a frame that can be linked integrally to it. With the term soil, of course, we are not limited to a walkable ground, but we can also refer to a seabed.

If device 1 ? capable of acquiring the wave motion created by a water basin, for example marine, it pu? also be bound to a quay wall rather than a dam.

The thrust element 3 ? configured to move an external body. Therefore, it is not other than an element capable of transmitting the motion acquired by the device 1 to an external body.

So, the main drive group 10 ? substantially suitable for converting the motion given by the stresses of a fluid, for example flowing in the hydraulic circuit 103 or simply defining a wave motion, into mechanical energy.

In this regard, the main transmission group 10? capable of acquiring oscillatory movements, for example in a vertical plane, of a carrier fluid and transmitting the same to the thrust element 3 and therefore to the external body.

Therefore, the main transmission group 10 mutually constrains the structure 2 and the thrust element 3.

The main transmission group 10, cos? like other parts of the device 1, it is hereinafter described in structural terms considering the constituent parts of the same following the modeling of construction science. With what? it is understood that, for example, when there are references to hinges and rods, they allude to physical elements that exhibit behavior similar to a rod and/or a hinge, in particular in a two-dimensional plane, but without any limitation regarding the actual physical components used.

For example, a zipper can be realized through a plurality? of joints, what? as an auction, in terms of modeling, pu? be referred to a bar, a beam or other elements suitable, in this case, to connect hinges or other elements having their own stiffness.

The main transmission unit 10 preferably comprises a first support 4, a second support 5 and a third support 6.

The first support 4, the second support 5 and the third support 6 preferably define similar shapes and can substantially be understood ideally as bars.

Preferably the first support 4 defines a first support plane 4a.

The first support 4 ? integrally connected to, or part of, an upper portion, preferably to the structure 2, or, in another example, to the third support 6 of a further main transmission unit 10.

Therefore, the first support plan 4a can? be constituted by the plane of interaction or constraint between the first support 4 and the structure 2. The first support 4 and the structure 2 can also be in one piece and therefore be made from the same component.

Furthermore, the first support 4 comprises at least two first hinges 40.

The hinges 40 are preferably made by mechanical joints which allow other elements to be connected lazily. These mechanical joints can be bolting suitable to allow preferably only a degree of lability, in particular the rotation around the hinge, to other elements.

Furthermore, these first hinges 40 are preferably mutually spaced by defining a first distance d?.

The first distance of ? preferably defined along the first support plane 4a. Furthermore, it? preferably constant, therefore the first support 4 defines a rigid rod.

Preferably the third support 6 defines a third support plane 6a.

The third support 6 ? preferably connected to, or part of, a lower portion, preferably to the thrust element 3 or to the first support 4 of a second main transmission unit 10.

The lower term, what? like the upper term used above, ? defined in reference to the ground along the vertical direction defined, for example, by gravitational acceleration.

Therefore, the third support plan 6a can? be constituted by the interaction or constraint plane between the third support 6 and the thrust element 3. The third support 6 and the thrust element 3 can also be in one piece and therefore be made from the same component.

Furthermore, the third support 6 comprises at least two third hinges 60.

Also the third hinges 60 are preferably made by mechanical joints which allow other elements to be connected lazily. These mechanical joints can be bolting suitable to allow preferably only a degree of lability, in particular the rotation around the hinge, to other elements.

Moreover, these third hinges 60 are preferably mutually spaced by defining a third distance d???.

The third distance d??? ? preferably defined along the third support plane 6a. Furthermore, it? preferably constant, therefore the third support 6 defines a rigid rod.

In addition, preferably, the distance d??? ? congruent with respect to the first distance d??. Alternatively, the first distance d? can? be higher or lower, by a percentage preferably between 18% and 25% and more? preferably between 21 and 23%, with respect to the third distance d???.

Preferably the second support 5 defines a second support plane 5a. The second support 5 ? preferably connected to the first support 4 and to the third support 6.

Therefore, the first support plan 5a ? between the first support plane 4a and the third support plane 6a.

Furthermore, the second support 5 comprises at least two second hinges 50.

The second support 5 pu? substantially comprising four second hinges 50, two second upper hinges 50a and two second lower hinges 50b.

The second hinges 50 are preferably made, like the others, by mechanical joints which allow other elements to be connected lazily. These mechanical joints can be bolting suitable to allow preferably only a degree of lability, in particular the rotation around the hinge, to other elements.

Said second hinges 50 are, moreover, preferably mutually spaced by defining a second distance d??. For example, as shown in Figs.4a-4c, the second support 5 can defining a second lower distance d1??, between said second lower hinges 50b, and a second upper distance d2??, between said second upper hinges 50a.

The second distance d?? ? preferably defined along the second support plane 5a. Furthermore, it? preferably constant, therefore the second support 5 defines a rigid rod.

Furthermore, the second distance d?? can? not be congruent to the first and third distance d? and d???, and pu? therefore be lower or higher than them.

For example, the second distance d?? can? be reduced, with respect to the third distance d??? of at least 3%, more? conveniently 5%.

Alternatively, as in the example of Figs.4a-4c, the second lower distance d1?? can? be less than both said first and said third distance d? and d???, of a percentage preferably between 40% and 50% and more? preferably between l?44 and 48%, with respect to the first distance d?. Furthermore the second upper distance d2?? ? greater than both said first and said third distance d? and d???, of a percentage preferably between 9% and 15% and more? preferably between l?11 and 13%, with respect to the third distance d???.

The device 1 therefore comprises connection means 7.

The connection means 7 are preferably able to connect the support 4, 5, 6. They preferably define a connection plane 7a. The connection plan 7a ? transversal, possibly precisely perpendicular, to the third support plane 6a. Therefore it ? substantially transversal, preferably perpendicular to the ground 3 and vertically joins the supports 4, 5, 6 with respect to the same ground.

The connection means 7 comprise at least two first rods 70 and two second rods 71.

The first rods 70 are preferably substantially rigid. Furthermore, they each define a first connection direction 70a.

The first connection direction 70a corresponds with the main development dimension of the rod 70 and therefore corresponds, for it, to the axial direction. Furthermore, the first connection direction 70a is non-deformable.

Preferably, the first rods 70 are able to constrain the first support 4 and the second support 5.

Pi? in detail, the two first rods 70 are each loosely constrained to a first hinge 40 and to a second hinge 50 so that the first connection directions 70a of the first rods 70 cross in the connection plane 7a. In the example of Figs.4a-4c, the first rods 70 are each loosely constrained to a first hinge 40 and to a second upper hinge 50a and substantially define the same geometry described.

Likewise, preferably, the second rods 71 are also rigid. Furthermore, they each define a second connection direction 71a.

The second connection direction 71a corresponds with the main development dimension of the rod 71 and therefore corresponds, for it, to the axial direction. Furthermore, the second connection direction 71a is non-deformable.

Preferably, the second rods 71 are able to constrain the second support 5 and the third support 6.

Pi? in detail, the two second rods 71 are each loosely constrained to a second hinge 50 and to a third hinge 60 so that the second connection directions 71a of the second rods 71 cross in the connection plane 7a.

In the example of Figs. 7a-7c the second rods 71 are each loosely constrained to a second lower hinge 50b and to a third hinge 60 and substantially define the same geometry described.

The first rods 70 and the second rods 71 are preferably congruent with each other, but they could also be different.

The device 1 thus essentially preferably defines two similar superimposed, consequential and specular structures, at least in a free condition, with respect to the second support plane 5a.

These structures are given by the first support 4, first rods 70 and second support 5 and by the second support 5, second rods 71 and third support 6.

In the example of Figs.4a-4c, the distance, in the vertical direction and in aligned configuration (Fig. 4a), between the first hinges 40 and the second upper hinges 50a? preferably very close to the first distance d?, and differs from it preferably by a percentage lower than 3%, preferably lower than 1%. Furthermore, the distance, in the vertical direction and in aligned configuration (Fig.4a), between the second lower hinges 50b and the third hinge 60 ? preferably greater than the third distance d???, by a percentage preferably comprised between 12% and 20% and more? preferably between 15% and 17%.

Furthermore, these structures can be substantially assimilated to articulated quadrilaterals or ?Chebyshev guides? which are used in the ?straight? when the side rods are crossed.

Structurally, the device 1, described up to now in terms of a two-dimensional model, can understand a plurality of pairs of first and second auctions 70, 71.

These first and second rods 70, 71 mutually coupled to other first and second rods 70, 71 are preferably parallel to the latter and arranged along parallel and spaced connection planes 7a.

Furthermore, the supports 4, 5, 6 can consist of or comprise a plurality of of different structural elements.

For example, the first support 4 pu? include a first support bar, the second support 5 pu? include a second support bar and the third support can? include a third support bar.

The support bars preferably, in this configuration, rigidly connect the hinges 40, 50, 60, respectively.

This configuration, pu? be used for devices 1 which extend vertically in a two-dimensional manner, i.e. mainly along the connection plane 7a and with two first rods 70 and two second rods 71.

In particular, the device 1 can? comprise side-by-side pairs of first rods 70 and second rods 71 connected to side-by-side pairs of support bars.

In this case, the hinges 40, 50, 60 comprise spacers able to connect the pairs of support bars and rods 70, 71 and the device 1? essentially made up of two structures, as described in the previous configuration, placed side by side and specularly constrained.

Alternatively, device 1 can? comprising a first support plate, a second support plate and a third support plate.

In detail, the first support 4 pu? include the first support plate, the second support 5 pu? include the second support plate and the third support can? include the third support plate.

The support plates are preferably coplanar with respect to the support planes 4a, 5a, 6a respectively and are suitable for connecting the hinges 40, 50, 60 respectively. These support plates can also be connected by two first rods 70 and two second rods 71 , or from a plurality? of pairs of rods 70, 71.

How already? mentioned, the device 1 preferably defines a free condition and at least one stress condition.

In the free condition, device 1 ? free with respect to stresses given, for example, by a fluid vector and the first support plane 4a, the second support plane 5a and the third support plane 6a are parallel to each other. In this condition, device 1 ? designed to support the upper structure.

In the stress condition, the device 1 is, on the other hand, stressed by external forces.

Advantageously, in order to allow the acquisition of the stress by the primary transmission unit 10, the device comprises at least one actuation element 8.

The implementation element 8 ? substantially configured to react to an external vertical stress Fy. With the vertical term we mean that, since the device 1 ? mainly used in such a way that the support plane 4a is substantially parallel to the ground, the force Fy ? substantially transverse or perpendicular to the ground.

The vertical stress Fy pu? be for example a force created by an aquatic wave motion. In this sense, the element of implementation 8 pu? trivially understand a float capable of reacting to the crests and troughs of waves generated by a water basin.

Or, preferably, the actuation element 8 can? comprise at least one cylinder 80.

The 80 cylinder? substantially a hydraulic piston and therefore includes a cursor capable of being pushed or retracted, in the same direction as the vertical stress Fy, by a fluid vector.

Therefore, preferably, in the energy generation plant 100, the cylinder 80 can? be in fluid passage connection with the distribution circuit 103. In any case, the actuation element 8 ? configured to transmit the vertical stress Fy at least along a transfer axis 8a.

The 8a transfer axis? preferably transversal to the first support plane 4a, even more? preferably perpendicular to it. Therefore, even if the vertical stress Fy changes direction, in any case the actuation element 8 transfers at least one component of the vertical stress Fy along the transfer axis 8a.

The second support 5 is therefore advantageously connected to the actuation element 8. This implies that, substantially, the primary transmission assembly is configured to move proportionally to the vertical stress Fy.

In particular, the connection between the second support 5 and the actuation element 8 allows the vertical stress Fy to be transformed and amplified along the third support plane 6a. Indeed, when the second support 5 ? moved by the vertical force Fy, the thrust element 3, which ? constrained to or includes the third support 6, is in turn substantially moved so? to realize both a displacement x and a horizontal stress Fx.

Displacement x and horizontal stress Fx are, of course, proportional to and dependent on vertical stress Fy.

Furthermore, displacement x and horizontal stress Fx are substantially directed along the third support plane 6a.

To further increase the amplification of the vertical stress Fy transformed into horizontal stress Fx, the device 1 can? include at least one pair of primary drive units 10.

Furthermore, if the device 1 comprises two primary transmission groups 10, it preferably also comprises two actuation elements 8.

Therefore, advantageously each of the second supports 5 of the two primary transmission units 10 ? preferably connected to a respective actuation element 8. Instead, each of the first supports 4 ? connected to, or part of, the same structure 2 and each of the third supports 6 ? connected, or part of, the same thrust element 3 so that? the horizontal stress Fx is given by the set of vertical forces Fy of each actuation element 8.

If there are more primary transmission groups 10, preferably, all the respective first support planes 4a are all coplanar.

Furthermore, all the third support planes 6a are also preferably coplanar. A configuration of this type is, for example, shown in Figs. 1-2 and 5-6b. This configuration? particularly advantageous inside 100 plants.

Preferably, in such systems 100, each cylinder 80 is constrained to the respective second support 5 at two opposite sides of the device 1. In this way, the actuation elements 8 can carry out the displacement x and the horizontal stress Fx proportionally to two mutually opposite vertical stresses Fy. So, the hydraulic apparatus 102 ? configured to feed the cylinders 80 alternately so that? when a cylinder 80 realizes a vertical force Fy in one direction, the other cylinder 80 realizes a respective vertical force Fy in the opposite direction.

In any case, the second support planes 5a of the second supports 5a are preferably always parallel to each other.

Of course, this operation? also suitable when the actuation element 8 includes simple floats, provided the device 1 is oriented in such a way that the wave crests first strike an actuation element 8 and then upwards. The device 1 can, in addition, comprise further components.

For example, device 1 can? comprise at least one secondary transmission unit 11.

If present, the secondary transmission group 11 ? capable of transmitting displacement x and horizontal stress Fx to an external body.

In detail, the secondary transmission unit 11 comprises at least one first rotary device 12.

The first rotary device 12 ? operatively connected to the thrust element 3. Furthermore, the first rotating device ? preferably configured to rotate proportionally to the displacement x around a first axis of rotation 3a. The first axis of rotation 3a is therefore preferably parallel to the third support plane 6a.

A similar transmission mechanism pu? be easily implemented by a connecting rod-crank mechanism as shown in Figs. Figs. 1-2 and 5-6b. Of course, other technically equivalent mechanisms can also be used to transmit motion.

In any case, the first rotary device 12 defines, when urged by the thrust element 3, a first rotation ??. The first rotation ?? is, of course, made around the first axis of rotation 3a.

In detail, the first rotating device 12 can be made by a first pulley 120.

The pulley 120 ? an element by itself? I notice that ? easily connectable to the thrust element 3.

The secondary transmission unit 11 preferably also comprises a second rotary device 14.

The second rotary device 14 ? substantially similar to the first rotary device 12. Therefore, also the second rotary device 14? configured to make a second rotation ???. In detail, the second rotating device 14 can comprise a second pulley 140 similar to the first pulley 120. Furthermore, the second rotating device 14 is configured to broadcast the second rotation ??? to an external body proportionally to the first rotation ??.

In fact, the secondary transmission unit 11 also comprises amplification means 13.

The amplifying means 13 is operatively connected to the first rotary device 12 and to the second rotary device 14. In particular, the amplifying means 13 is configured to transmit the first rotation ?? to the second rotating device 14 according to a predetermined transmission ratio so as to carry out the second rotation ???.

In one embodiment, the amplifying means 13 may comprise a third pulley 130.

The third pulley 130 pu? be of the same type as the first pulley 120 and the second pulley 140.

So if you intend to broadcast a second spin ??? more wider than the first rotation ?? can? be sufficient to make a second pulley 140 with a smaller diameter than the third pulley 130 and a third pulley 130 with a smaller diameter than the first pulley 120.

Also, the third pulley 130 pu? be connected to the first pulley 120 via a first belt 123. The third pulley 130 can also be connected to the second pulley 140 via a second belt 143.

Preferably, the third pulley 130 comprises a first portion 131 and a second portion 132.

The first portion 131 defines a smaller diameter than the first pulley 120 and ? connected to the first pulley 120 via the first belt 123.

The second portion 132 preferably defines a diameter greater than the first portion 131 and the second pulley 140 and ? connected to the second pulley 140 via the second belt 143.

In this way ? possible to greatly amplify the second rotation ??? compared to the first rotation ??.

The device 1, advantageously, can also include a third transmission unit 15.

The third transmission group 15 ? substantially configured to transmit a rotational motion proportional to the second rotation ??? to an external body.

In detail, the third transmission unit 15 can? be configured to transmit a rotary motion to an external generator.

Inside a plant 100, preferably, the electric generator 101 is operatively connected to the third transmission group 15 in such a way as to generate electric energy starting from the rotary motion imposed by the third transmission group 15.

even more in detail, the third transmission group 15 comprises at least a first transmission apparatus 16.

The first transmission apparatus 16 ? operatively connected to the second rotating device 14, for example to the second pulley 140. Furthermore, it is configured to convert the second rotation ??? in a third rotation ????.

The third rotation ???? ? at least proportional to the second rotation ???, possibly of the same intensity? of the second rotation ???.

However, the third rotation ???? ? made around a predetermined transmission axis 16a.

The transmission axis 16a naturally depends on the type of first transmission apparatus 16 adopted. For example, if the? Return apparatus 16 ? angular, the axis of reference 16a can? substantially be perpendicular to the direction of rotation of the second rotating device 14. Or, if the transmission? linear, the return axis 16a can? be aligned with the axis of rotation.

Therefore, preferably, the electric generator 101 of the plant 100 is configured to generate electrical power proportionally to the third rotation ????.

Naturally, the third transmission group 15 can? include additional components. For example, the third transmission group 15 pu? include at least one flywheel 17. This flywheel 17, if present, ? operatively connected to the first transmission apparatus 16.

Furthermore, the third transmission unit 15 can? include other quickdraws and/or a dynamometer. Or, again, the third transmission group 15 can? also include a disc brake. These components can therefore be arranged, in series, between the first transmission apparatus 16 and the electric generator 101, if the device 1 is in use in a 100 system.

In order to further improve the performance of the device, other features may be adopted.

Preferably, the device 1 also comprises a pair of secondary transmission units 11.

These secondary transmission groups 11 can therefore be configured in such a way as to be simultaneously urged by the same thrust element 3. In particular, preferably, each of the second rotating devices 14? operatively connected to the first transmission apparatus 16.

In this way, the third rotation ???? ? basically the result of both second rotations ???.

Being the second rotations ??? substantially equiverse and, above all, alternate pu? be advantageous to take further precautions.

In the preferred embodiment, the first transmission apparatus 16 defines an angular transmission.

Therefore, the first transmission apparatus 16 comprises at least a first shaft 160, a second shaft 161 and a third shaft 162. The shafts 160, 161, 162 are common mechanical shafts capable of transmitting a rotation to components such as, for example, a ring gear or other elements capable of transmitting movement.

The first shaft 160?, in particular, is configured to rotate about the transmission axis 16a, carrying out the third rotation ????.

The second shaft 161 and the third shaft 162 are, on the other hand, connected to a respective second rotating device 14.

Is the connection between the second shaft 161 and the second rotary device 14 ? advantageously achieved by means of a first one-way clutch 163a.

The first one-way clutch 163a ? a mechanical element known to those skilled in the art which substantially allows traction to be transmitted between two shaft portions in one direction of rotation and to make the rotation of one shaft idle with respect to the other when the direction of rotation is ? opposite to the previous one.

The connection between the third shaft 162 and the second rotary device 14 is also? advantageously achieved by means of a second one-way clutch 163b.

Advantageously, the one-way clutches 163a, 163b are configured to transmit the second rotations ??? in mutually opposite directions.

Does this mean that the traction direction of the second and third shaft 161, 162 ? substantially opposite and, therefore, they can rotate the first shaft 160 alternately.

Second shaft 161 and third shaft 162 are also facing each other and mirror each other since the transmission is preferably angular. Thus, in this configuration, the clutches 163a, 163b allow the third rotation to be alternately powered ???? with each of the second rotations ???.

The operation of the device 1 previously described in structural terms? the following.

When it ? in free condition all the support planes 4a, 5a, 6a are mutually parallel and the rods 70, 71 preferably cross at a point included in the geometric axis of the device 1.

When the device 1 passes from the free condition to the stress condition due to external vertical stresses Fy which impress displacements along the transfer axis 8a on the ends of the second supports 5, the second supports 5 are subjected to rotation and transmit the displacement x and the horizontal stress Fx to the thrust element 3.

When each second support 5 moves, the crossing point of the rods 70, 71 is misaligned from the axis of the device 1 by virtue of of the inclination of the second rods 71 in a manner corresponding to the inclination of the second support plane 5a.

Similarly, the first 70 rods tilt.

Following the rotation of the support seconds 5 given by a wave motion, the thrust element 3 can? oscillate performing displacements x and transmitting, at the same time, a horizontal stress proportional to the vertical stress Fy.

By oscillating, the thrust element 3 moves the first rotary device 12 and, through the amplifying means 13, also the second rotary device 14.

Do oscillations given by the displacement x in the third support plane 6a correspond to oscillations of the first rotation ?? around the first axis of rotation 13a and, therefore, amplified oscillations of the second rotation ???.

The first transmission apparatus 16 therefore allows the third rotation to be transmitted continuously ???? to an external generator, for example the electric generator 101, directly or through other components such as the flywheel 17 or any other transmissions.
