Abstract

The present invention relates more specifically to a system for optimising mechanical transmission using kinetic energy, so that it can be actuated by any type of force, achie6ving efficiency due to being constantly balanced, as well as improved performance in the use of the kinetic energy depending on the technology, thus creating a novel concept for optimising mechanical transmission, making potential energy available for general use, capable of producing high-performance work, requiring a small amount of force to keep it running to in order to meet any desired demand. The inventive concept lies in two rods, a primary rod (1.5) and a secondary rod (1.15), and in a set of freewheeling drive sprockets (1.4), a transmission chain (1.12), a driven sprocket (1.6), a driven gear (1.7), a drive gear (1.11), and a secondary shaft (1.14), wherein by absorbing the initial external kinetic power, the set of freewheeling drive sprockets (1.4), arranged at the centre of the system, transfers this kinetic power through the transmission chain (1.12) to the driven sprocket (1.6) and the driven gear (1.7), which is directly connected to the drive gear (1.11). When actuated together, these mechanisms transfer the initial external kinetic power to the end of the system, causing it to rotate as a whole, which allows the secondary rod (1.15) to return the kinetic power back to the secondary shaft (1.14) arranged in the centre of the system and for the resulting kinetic power to be drawn therefrom.

Description

MECHANICAL TRANSMISSION OPTIMIZER SYSTEM VIA KINETIC ENERGY Technological sector of the invention

[0001] The present invention relates more specifically to a mechanical transmission optimization system via kinetic energy with the aim of being driven by any type of force, achieving performance, thus creating a new concept of mechanical transmission optimization, making potential energy available for general use, capable of performing high-performance work, requiring a small amount of force to keep it running to meet any desired demand. State of the art

[0002] Optimization devices are increasingly being researched due to growing environmental concerns, rising global warming, and the consumption of polluting fuels. Therefore, there is a growing need for systems with optimized performance to achieve the best possible performance and produce increasingly cleaner energy.

[0003] Several mechanisms have already been created, but performance and efficiency have never been achieved to address not only the problems mentioned above, but also problems of another nature, which will be mentioned based on known solutions.

[0004] Patent document W02003085815 - titled “Progressive Hydrokinetic Energy Converter” shows a progressive hydrokinetic energy converter that has several deficiencies that result in energy loss, premature wear of parts, reducing its useful life and increasing maintenance costs, such as: I) The hydraulic pump and steering wheel drive system, using belts, has a short service life; the number of parts used in the transmission is significant and the energy loss due to friction is considerable; II) The general lubrication system, with low viscosity oil, causes premature wear on components, in addition to excessive noise; III) The system for fixing the cylinders to the housing, using two points, does not provide perfect alignment of the cylinders with the housing, causing vibration, wear on the parts and a consequent reduction in their useful life; IV) The output shaft is one piece with the angular track gear, which means that, in the event of wear, the part must be completely replaced, which increases maintenance costs; V) Using a solid steering wheel causes vibration and noise; VI) The pistons, which should only have linear movement, present rotational movement, causing greater wear on the sealing components.

[0005] The Lysekil Project was launched at Uppsala University in Sweden. Its goal was to develop a device using a linear generator. When the float moves, it activates, via a cable, a linear generator fixed below it. This generator consists primarily of a piston that performs a linear motion, to which magnets are attached, and a fixed stator with coils. When the piston and magnets move, it alters the magnetic field within the stator coils, generating electrical energy. These mechanisms tend to develop considerable forces on their respective stops in high-altitude waves, requiring the use of very robust and expensive parts. Energy converters with moving parts on the sea surface are subject to the harsh marine environment, such as fouling, in addition to manufacturing (particularly sealing) and maintenance difficulties. Novelty and purpose of the invention

[0006] In this context, the present invention aims to address several more pronounced technical deficiencies - a key requirement is that the new system of the invention be simple, have few moving parts, and entail minimal mechanical losses, as well as minimize manufacturing and assembly costs. Added to this list is the absence of the use of hydraulic, pneumatic, or electronic systems, which would require a reduction in transmissions for its operation; consequently a low rate of wear and maintenance of its components, it does not depend on equipment with advanced technologies in addition to being able to use any type of force for its operation, which makes the present invention quite accessible, enabling its production on a large, medium or small scale, always optimizing performance in its operation, which provides less environmental impacts, also contributes to a lower demand for polluting fuels and consequently to slowing down global warming, and can also meet any desired application. Description of the attached drawings

[0007] In order for the present invention to be fully understood and put into practice by any technician in this technological sector, it will be described in a clear, concise and sufficient manner, based on the attached drawings, which illustrate and support it, listed below: Figure 1 represents the side view of the system; Figure 2 represents the front view of the system; Detailed description of the invention

[0008] The present system, as shown in Figures 1 and 2, is composed of a primary structure (1.1), primary shaft (1.2), primary bearings (1.3), set of driving idle crowns (1.4), primary shaft (1.5), driven crown (1.6), driven gear (1.7), intermediate shafts (1.8), intermediate bearings (1.9), intermediate rods (1.10), traction gear (1.11), transmission chain (1.12), secondary structure (1.13), secondary shaft (1.14), secondary rod (1.15), secondary bearings (1.16), counterweight (1.17), support base (1.18).

[0009] The system is composed of one side of the support base (1.18) by the primary shaft (1.2), fixed to the primary structure (1.1), through the primary bearings (1.3), arranged on this primary axis (1.2), the set of motor idler crowns (1.4), attached to each other in parallel where the initial external power enters to activate the system, as well as the primary rod (1.5), arranged on the rod primary (1.5), are on one side of its end, intermediate bearings (1.9) and intermediate shaft (1.8) contained in it the driven crown (1.6) and the driven gear (1.7), which being affixed to the same intermediate shaft (1.8), will be driven together by the set of motor crazy crowns (1.4), through the transmission chain (1.12), and at the other end of the primary rod (1.5), intermediate bearings (1.9), intermediate shafts (1.8), on the opposite side of the support base (1.18), frontally is affixed the secondary structure (1.13) and to it the secondary shaft (1.14), supported by the secondary bearings (1.16) and on this secondary shaft (1.14) the secondary rod (1.15), which at both ends are arranged intermediate bearings (1.9), as well as intermediate shafts (1.8). The connection between the primary rod (1.5) and the secondary rod (1.15) is made up of intermediate rods (1.10), with intermediate bearings (1.9), both supported by the intermediate shafts (1.8), the one on the side of the mechanical transmission devices of the system, has the traction gear (1.11) attached, while the counterweight (1-17) is attached to the intermediate rod (1.10) on the opposite side.

[0010] The system, when activated, has the initial external kinetic power absorbed by the set of idler motor crowns (1.4) and will make them rotate in this version seen from the front in a clockwise direction, through the transmission chain (1.12), which is interconnected to the driven crown (1.6), and finding the driven gear (1.7) attached to the same intermediate shaft (1.8), will activate both, making them rotate together in the same clockwise direction as described above, a mechanism in which the driven gear (1.7), being directly coupled to the traction gear (1.11), attached to the respective intermediate rod (1.10), when absorbing this kinetic power, will result in the total activation of the system, causing it to rotate completely in the opposite direction or counterclockwise in relation to the direction of rotation described above. The system will always remain balanced, whether static or in motion due to the counterweight (1.17), attached to the respective intermediate rod (1.10), after passing by the system the resulting kinetic power will be removed through the secondary shaft (1.14), to meet the desired demands.

[0011] It is important to emphasize that in the primary shaft (1.5), to meet the desired demand, larger quantities of intermediate bearings (1.9) and / or intermediate shafts (1.8) and / or driven crowns (1.6) and / or transmission chains (1.12) may be coupled. It is important to emphasize that the figures and descriptions provided are not intended to limit the system's execution method. All components responsible for the necessary mechanical transmissions arranged in the primary shaft (1.5) may also be transferred to the secondary shaft (1.15), also transferring the set of idle driving crowns (1.4) to the secondary shaft (1.14). The system components responsible for mechanical transmissions may be replaced, the transmission chain (1.12) by belts, the crowns by gears or pulleys, as well as any types of transmissions already existing to meet the desired demand.
