Description

PRINCÍPIO DE CONVERSÃO MECÂNICA DE MOVIMENTO POR EIXO PRINCIPLE OF MECHANICAL CONVERSION OF MOVEMENT BY AXIS
INCLINADO TILTED
Campo da invenção field of invention
[001] A presente invenção pertence ao campo de sistemas mecânicos básicos, que podem ser utilizados como base de qualquer tipo de máquina ou sistema onde haja a necessidade de um movimento cíclico com amplitude variável. Especificamente em sistemas mecânicos que ajustam sua amplitude sem a interrupção do movimento/processo. [001] The present invention belongs to the field of basic mechanical systems, which can be used as the basis of any type of machine or system where there is a need for a cyclic movement with variable amplitude. Specifically in mechanical systems that adjust their amplitude without interrupting the movement/process.
Fundamentos da invenção Fundamentals of the invention
[002] Nos processos cíclicos onde há necessidade de controlar a amplitude do movimento e as grandezas consequentes desse movimento (como força, torque, aceleração, deslocamento, ângulo, entre outros) as técnicas comerciais atuais possuem algumas limitações ou desvantagens dependendo das frequências desejadas. [002] In cyclic processes where there is a need to control the amplitude of movement and the consequent magnitudes of this movement (such as force, torque, acceleration, displacement, angle, among others) current commercial techniques have some limitations or disadvantages depending on the desired frequencies.
[003] Em geral quanto maior a frequência dos ciclos, maior é a complexidade de controle por se tratar de controles eletrónicos avançados. [003] In general, the higher the frequency of the cycles, the greater the control complexity, as these are advanced electronic controls.
[004] A alta complexidade gera custos elevados inviabilizando estas técnicas a certas aplicações. Outra limitação que podemos destacar das técnicas tradicionais é a limitação de frequência mecânica do sistema, como em sistemas com fusos, onde é necessário inverter o sentido da rotação para inverter o movimento. [005] Como a inversão de movimento envolve acelerar e desacelerar a rotação, a frequência máxima final é drasticamente comprometida. Tipicamente em sistemas de servo atuadores comerciais, é possível atingir até 10Hz, ainda assim comprometendo a máxima amplitude do movimento, que reduz consideravelmente. [004] The high complexity generates high costs, making these techniques unfeasible for certain applications. Another limitation that we can highlight in traditional techniques is the mechanical frequency limitation of the system, as in systems with spindles, where it is necessary to reverse the direction of rotation to reverse the movement. [005] As the inversion of motion involves accelerating and decelerating the rotation, the final maximum frequency is drastically compromised. Typically in commercial servo actuator systems, it is possible to reach up to 10Hz, still compromising the maximum range of motion, which reduces considerably.
[006] Com base no exposto podemos citar o seguinte estado da técnica como útil à compreensão da presente invenção: RU2235241 e BR102018014697. [006] Based on the above, we can cite the following state of the art as useful for understanding the present invention: RU2235241 and BR102018014697.
[007] O documento russo, RU2235241 , depositado em 2003, nos ensina como realizar a transmissão de movimento por eixo inclinado em sistemas mecânicos de embreagens para espaços herméticos. [007] The Russian document, RU2235241, deposited in 2003, teaches us how to perform the transmission of motion by inclined axis in mechanical clutch systems for hermetic spaces.
[008] Já o documento depositado no Brasil, BR102018014697, nos ensina um sistema de transmissão de movimento mecânico através de carnes para operação de um motor de combustão interna. [008] The document deposited in Brazil, BR102018014697, teaches us a mechanical movement transmission system through meats for the operation of an internal combustion engine.
[009] Aspectos interessantes destas soluções se evidenciam, como a utilização de diferentes tipos de meios mecânicos para transmissão do movimento. [009] Interesting aspects of these solutions are evident, such as the use of different types of mechanical means for motion transmission.
[0010] Com os ensinamentos e conceitos que a técnica anterior nos ensina e revela, é possível notar uma característica marcante dentre os documentos, que é a complexidade de suas disposições construtivas, amplitude fixa entre outras limitações. [0010] With the teachings and concepts that the previous technique teaches and reveals, it is possible to notice a striking feature among the documents, which is the complexity of its constructive provisions, fixed amplitude, among other limitations.
[0011] Também é interessante citar os conhecimentos tradicionais da técnica anterior, dentre eles ressalta-se o sistema biela-manivela. O sistema biela-manivela sem dúvida é um dos pioneiros do campo tecnológico de conversão de movimento. [0012] A presente invenção traz características inovadoras que vão muito além do referido estado da técnica. A invenção resolve os problemas do atual estado da técnica ao prover um sistema que compreende: eixo inclinado (1), elemento de inclinação (2), eixo de rotação não inclinado (3), mancais (4), rolamento linear (5), bloco de conversão (6), atuador (7), estrutura (8) e guias lineares (9). [0011] It is also interesting to mention the traditional knowledge of the prior art, among which the connecting rod-crank system stands out. The connecting rod-crank system is undoubtedly one of the pioneers in the technological field of motion conversion. [0012] The present invention brings innovative features that go far beyond the aforementioned state of the art. The invention solves the problems of the current state of the art by providing a system comprising: inclined axis (1), inclination element (2), non-inclined rotation axis (3), bearings (4), linear bearing (5), conversion block (6), actuator (7), structure (8) and linear guides (9).
[0013] De maneira vantajosa, a presente solução, além de apresentar nova disposição construtiva, vem proporcionar um sistema capaz de realizar a variação da amplitude do movimento final sem a interrupção do processo e/ou do movimento. [0013] Advantageously, this solution, in addition to presenting a new constructive arrangement, provides a system capable of performing the variation of the amplitude of the final movement without interrupting the process and/or movement.
[0014] Também é inventivo a característica da invenção de permitir a variação da amplitude final de forma gradual e contínua. [0014] It is also inventive the characteristic of the invention to allow the variation of the final amplitude in a gradual and continuous way.

Descrição da Invenção Description of the Invention
[0016] A presente invenção se trata de um sistema mecânico de conversão mecânica de movimento com base na utilização de um eixo inclinado, solucionando os problemas da técnica ao prover um novo sistema, totalmente simplificado quando comparado à técnica anterior, com possibilidade de variação de sua amplitude em seu funcionamento, sem a necessidade de troca de componentes ou parada do conjunto que o sistema está empregado. [0016] The present invention deals with a mechanical system of mechanical conversion of movement based on the use of an inclined axis, solving the problems of the technique by providing a new system, totally simplified when compared to the previous technique, with the possibility of variation of its breadth in its operation, without the need to change components or stop the set that the system is employed.
[0017] Conforme a presente invenção e de acordo com as figuras de 1 a 5, o princípio de conversão mecânica compreende: eixo inclinado (1), elemento de inclinação (2), eixo de rotação não inclinado (3), mancais (4), rolamento linear (5), bloco de conversão (6), atuador (7), estrutura (8) e guias lineares (9). [0018] O sistema desenvolvido, por ser uma conversão puramente mecânica, proporciona a vantagem de reduzir consideravelmente a complexidade de controle, reduzindo consequentemente também o custo do sistema. [0017] According to the present invention and according to figures 1 to 5, the principle of mechanical conversion comprises: inclined axis (1), inclination element (2), non-inclined rotation axis (3), bearings (4 ), linear bearing (5), conversion block (6), actuator (7), frame (8) and linear guides (9). [0018] The developed system, as it is a purely mechanical conversion, provides the advantage of considerably reducing the control complexity, consequently also reducing the cost of the system.
[0019] Também não possui a limitação encontrada na conversão por fusos quanto a velocidade de inversão de movimento, pois o movimento rotacional inicial é contínuo e em um único sentido, podendo assim alcançar grandes velocidades e/ou frequências. [0019] It also does not have the limitation found in the conversion by spindles regarding the speed of movement inversion, since the initial rotational movement is continuous and in a single direction, thus being able to reach high speeds and/or frequencies.
[0020] Um grande diferencial em relação aos carnes mecânicos ou excêntricos é a possibilidade de variar a amplitude do movimento linear final sem interrupção do movimento/processo. [0020] A great differential in relation to mechanical or eccentric cams is the possibility of varying the amplitude of the final linear movement without interrupting the movement/process.
[0021] Ainda sobre a variação da amplitude, ela é variada em relação a movimentação dos mancais (4) sob as guias lineares (9) e também do bloco de variação (6) que se desloca verticalmente, podemos ver muito bem ilustrado nas figuras 3 a 5. [0021] Still on the amplitude variation, it is varied in relation to the movement of the bearings (4) under the linear guides (9) and also of the variation block (6) that moves vertically, we can see very well illustrated in the figures 3 to 5.
[0022] Adicionalmente, outra característica do princípio de conversão mecânica de movimento está na variação e/ou ajuste da amplitude do movimento linear que se dá de forma contínua e gradual, sem degraus ou saltos de amplitude, resultando em uma transformação suave e precisa do movimento. [0022] Additionally, another characteristic of the mechanical motion conversion principle is the variation and/or adjustment of the amplitude of the linear movement that occurs continuously and gradually, without steps or amplitude jumps, resulting in a smooth and precise transformation of the movement.
[0023] Este sistema pode ser utilizado para qualquer necessidade de movimento linear cíclico que necessitem de ajuste de deslocamento linear, como processos de fabricação, motorização de veículos, controles diversos em veículos, máquinas de testes e ensaios (como ensaios cíclicos de fadiga ou desgaste, ensaios de vibração entre outros), sistemas de vibração que necessitem variar a amplitude do movimento ou som, agitadores, misturadores, entre outros. [0023] This system can be used for any need for cyclic linear movement that require linear displacement adjustment, such as manufacturing processes, vehicle motorization, various vehicle controls, testing and testing machines (such as cyclic fatigue or wear tests , vibration tests, among others), systems of vibration that need to vary the amplitude of the movement or sound, agitators, mixers, among others.
[0024] O movimento circular antes da linearização também pode ser aproveitado com as mesmas vantagens que o princípio apresenta. [0024] The circular movement before linearization can also be used with the same advantages that the principle presents.
[0025] O princípio de conversão de movimento mecânico se dá através de um eixo inclinado que converte um movimento rotacional simples em uma rotação com diferentes amplitudes ao longo dele, sendo que este último movimento pode ser convertido em movimento linear através de conceitos já conhecidos, como (duas guias lineares (X, Y), um braço articulado (biela), pino guia, entre outros). Este movimento linear consequentemente terá amplitude variável e/ou ajustável conforme necessidade de cada processo. [0025] The principle of conversion of mechanical movement occurs through an inclined axis that converts a simple rotational movement into a rotation with different amplitudes along it, and the latter movement can be converted into linear movement through already known concepts, such as (two linear guides (X, Y), an articulated arm (rod), guide pin, among others). This linear movement will consequently have variable and/or adjustable amplitude according to the needs of each process.
Exemplos de concretização da invenção Examples of embodiment of the invention
[0026] Conforme um primeiro aspecto principal, a presente invenção foi concretizado como um sistema de conversão mecânica de movimento por eixo inclinado para ser aplicado em qualquer lugar que necessite transmitir movimento, o qual é particularmente utilizado em aplicações que necessitem a variação da amplitude do movimento de forma contínua e gradual sem a interrupção do sistema. [0026] As a first main aspect, the present invention was implemented as a system of mechanical conversion of movement by inclined axis to be applied anywhere that needs to transmit movement, which is particularly used in applications that need the variation of the amplitude of the movement continuously and gradually without interrupting the system.
[0027] Os esboços vistos nas imagens são apenas representações simplificadas, para facilitar o entendimento. O ponto de partida está no eixo inclinado (1), que pode ser constituído por uma barra cilíndrica, eixo retificado, guia linear ou qualquer outro elemento que sirva de guia linear por onde o bloco de conversão (6) irá se deslocar. [0028] Esse eixo inclinado deve ser fixado à um disco (2) ou outro elemento que ao mesmo tempo que mantém o eixo inclinado, fornece um eixo de rotação não inclinado (3) por onde será realizada a motorização/rotação de entrada. Este eixo de rotação não inclinado pode ser fixado à estrutura (8) por meio de mancais (4) ou outro elemento que permita a livre rotação e restrinja a movimentação linear. [0027] The sketches seen in the images are just simplified representations, to facilitate understanding. The starting point is on the inclined axis (1), which can consist of a cylindrical bar, ground axis, linear guide or any other element that serves as a linear guide through which the conversion block (6) will move. [0028] This inclined axis must be attached to a disk (2) or another element that, while maintaining the inclined axis, provides a non-inclined axis of rotation (3) through which the motorization/input rotation will be performed. This non-inclined axis of rotation can be fixed to the structure (8) by means of bearings (4) or another element that allows free rotation and restricts linear movement.
[0029] Este primeiro conjunto, constituído pelo Eixo inclinado (1), elemento de inclinação (2), Eixo de rotação (3) e mancais (4), deve poder se movimentar horizontalmente em relação ao segundo conjunto que estará fixo horizontalmente e livre verticalmente. [0029] This first set, consisting of the inclined shaft (1), tilting element (2), rotation shaft (3) and bearings (4), must be able to move horizontally in relation to the second set, which will be fixed horizontally and free vertically.
[0030] Este movimento linear horizontal é o que permitirá ajustar a amplitude do movimento final, pois no centro do eixo inclinado onde é coincidente com o eixo rotacional a amplitude é zero e quanto mais se distancia do centro maior será a amplitude. Isso pode ser visto nas imagens 3, 4 e 5. [0030] This horizontal linear movement is what will allow you to adjust the amplitude of the final movement, because in the center of the inclined axis where it coincides with the rotational axis the amplitude is zero and the further away from the center the greater the amplitude will be. This can be seen in images 3, 4 and 5.
[0031] A movimentação horizontal linear do primeiro conjunto pode ser realizada utilizando qualquer tipo de elemento que permita apenas a movimentação linear (9), como eixos e rolamentos lineares, guias e patins de esferas, entre outros. O segundo conjunto deve possuir algum elemento que permita o deslocamento com baixo atrito (5) através do eixo inclinado, como um rolamento linear de esferas ou elementos similares. [0031] The linear horizontal movement of the first set can be performed using any type of element that only allows linear movement (9), such as linear axes and bearings, guides and ball slides, among others. The second set must have some element that allows displacement with low friction (5) through the inclined axis, such as a linear ball bearing or similar elements.
[0032] Este elemento (5) também deve estar associado ao bloco de conversão (6) por meio de um elemento que permita apenas livre rotação, como um rolamento radial. Dessa forma o rolamento linear (5) irá rotacionar junto com o eixo inclinado, porém o bloco de conversão (6) receberá apenas o movimento planar circular, sem rotacionar. [0033] Agora que se tem um movimento planar circular é possível por meios já conhecidos separar o movimento planar em dois movimentos lineares, ou seja, dois eixos de movimentação. Para a maioria das aplicações será necessário utilizar apenas um dos movimentos lineares, descartando o segundo. Porém ambos podem ser utilizados se necessário. [0032] This element (5) must also be associated with the conversion block (6) by means of an element that only allows free rotation, such as a radial bearing. In this way, the linear bearing (5) will rotate along with the inclined axis, but the conversion block (6) will only receive the circular planar movement, without rotating. [0033] Now that we have a circular planar movement, it is possible by means already known to separate the planar movement into two linear movements, that is, two axes of movement. For most applications it will be necessary to use only one of the linear movements, discarding the second. But both can be used if necessary.
[0034] O método exemplificado nas imagens para essa conversão foi um bloco de conversão (6) que despreza os movimentos horizontais e transfere o movimento vertical para o atuador (7), que por sua vez foi restringido à movimentos lineares por meio de um rolamento linear ou elemento similar fixado à estrutura (8). [0034] The method exemplified in the images for this conversion was a conversion block (6) that disregards the horizontal movements and transfers the vertical movement to the actuator (7), which in turn was restricted to linear movements through a bearing linear or similar element fixed to the structure (8).
[0035] Para não causar um esforço de torção sobre os elementos, é necessário que este rolamento linear (7) permita apenas deslocamento linear, restringindo também os movimentos rotacionais. Dependendo da carga necessária ao processo pode ser utilizado mais de um elemento inclinado (eixos, guias ou outros), sendo que para fins dos cálculos deve ser utilizado o eixo inclinado virtual central. [0035] In order not to cause a torsional effort on the elements, it is necessary that this linear bearing (7) only allows linear displacement, also restricting rotational movements. Depending on the load required for the process, more than one inclined element can be used (axes, guides or others), and the central virtual inclined axis must be used for calculation purposes.
[0036] A motorização do eixo rotacional (3) pode ser realizada por qualquer meio já conhecido como hidráulico, pneumático, eletromagnético, mecânico. [0036] The motorization of the rotational axis (3) can be performed by any known means such as hydraulic, pneumatic, electromagnetic, mechanical.
[0037] O eixo inclinado pode ser reduzido praticamente pela metade caso seja necessário reduzir o espaço utilizado, pois é necessário apenas um dos lados a partir do centro. É favorável deixar o outro lado simétrico para fins de evitar vibração e desbalanceamento do sistema no caso de sistemas de alta rotação, porém através de cálculos é possível compensar a massa retirada através de um contrapeso de menor comprimento. [0038] O ângulo do eixo inclinado pode ser definido conforme a necessidade da amplitude do movimento e também está relacionado a força necessária à aplicação. Quanto maior o ângulo em relação ao eixo de giro, maior será a amplitude do movimento final e consequentemente será necessário mais torque de entrada para gerar a mesma força, devido ao braço de alavanca maior. [0037] The inclined axis can be reduced by almost half if it is necessary to reduce the space used, as only one side is needed from the center. It is favorable to leave the other side symmetrical in order to avoid vibration and unbalance of the system in the case of high rotation systems, however, through calculations, it is possible to compensate the mass removed through a counterweight of shorter length. [0038] The angle of the inclined axis can be defined according to the need for the range of motion and is also related to the force required for the application. The greater the angle in relation to the axis of rotation, the greater the amplitude of the final movement and consequently, more input torque will be required to generate the same force, due to the larger lever arm.
[0039] Um movimento linear (gerado manualmente ou automaticamente por qualquer meio) é necessário para posicionar o primeiro conjunto na posição que gere a amplitude desejada. Esse posicionamento pode ser realizado com o restante do sistema em funcionamento, alterando assim a amplitude do movimento cíclico gradualmente até o valor desejado. [0039] A linear movement (generated manually or automatically by any means) is required to position the first set in the position that generates the desired amplitude. This positioning can be performed with the rest of the system in operation, thus changing the amplitude of the cyclic movement gradually until the desired value.
[0040] O conjunto completo também pode ser montado sobre outros mecanismos de posicionamento para assim ter ajuste do centro do movimento (conhecido em várias áreas como offset). Desta forma é possível, além da amplitude, ajustar o ponto central do movimento sem interromper o processo/movimento. [0040] The complete set can also be mounted on other positioning mechanisms to adjust the center of movement (known in many areas as offset). In this way, it is possible, in addition to the amplitude, to adjust the central point of the movement without interrupting the process/movement.
