Campo da InvencioInventory Field
A presente invengao se refere a uma haste (biela) para interligar ο pistao a extremidade do cilindro de compressores Iinearest a qual foi idealizada e desenvolvida para proporcionar grande rigidez axial, grande resistencia a flambagem e baixa rigidez transversal resultando, porta η to, em uma pega relativamente flexivel destinada, de forma mais especifica, a operagao em compressores Iineares de aIta frequencia.The present invention relates to a rod (connecting rod) for interconnecting to the piston the end of the Iinearest compressor cylinder which has been designed and developed to provide great axial stiffness, great buckling resistance and low transverse stiffness resulting, therefore, in a Relatively flexible handle is more specifically intended for operation on high frequency linear compressors.
Fundamentos da InvencaoFoundations of the Invention
Conforme e do conhecimento da tecnica, nos compressores Iineares ο movimentoAs is well known in the art, in motion compressors
- 1. - -- 1. - -
reciprocante do pistao esta diretamente relacionado ao movimento ressonante do mecanismo, e seu funcionamento demanda a utilizagao de bielas em forma de hastes que interligam ο pistao ao elemento ressonante do compressor, as quais geralmente sao retilineas, rigidas e de segao transversal uniforme.The reciprocating piston is directly related to the resonant movement of the mechanism, and its operation requires the use of rod-shaped connecting rods that interconnect the piston with the resonant element of the compressor, which are generally straight, rigid and of uniform cross section.
Ocorre, porem, que as caracteristicas da biela utilizada impactam em pelo menos dues condiQ5es de operagao importantes dos compressores: na sua vida util e no ruido gerado pelo. funcionamento:do— eqyipam^nto. Neste^sentidoi JcabeJembrar qUe.os.esforgos^ oriundos do movimento reciprocante da haste e da ressonancia da mola utilizada sao esforgos axiais e transversals que, alem de contribuirem para a geragao de ruido proveniente： do impacto/atritp_^entre ο pistao e_as=pared_es_laterais do . cilindro, tambem. podem causar a falha da biela por fadiga ou ainda acelerar ο desgaste do pistao, pois quanto maior os esforgos transversals transmitidos da biela ao pistao, maior e a forga de atrito entre ο pistao e ο cilindro, e maior e a taxa de desgaste do pistao.However, the characteristics of the connecting rod impact on at least two important operating conditions of the compressors: in their useful life and in the noise generated by the. operation: do— eqyipam ^ nto. In this sense, it is important to remember that the efforts that come from the reciprocating movement of the stem and the resonance of the spring used are axial and transverse stresses that, besides contributing to the noise generation ： the impact / attrition between the piston and the sidewalls. of . cylinder, too. may cause fatigue piston rod failure or accelerate piston wear, because the greater the transverse stresses transmitted from piston to piston, the greater the frictional force between piston and cylinder, and the higher the piston wear rate. .
Tendo em vista tais condig5es de opera^ao, algumas solugSes tecnicas vem sendo desenvolvidas visando a eliminagao dos problemas mencionados como, por exemplo, aquela apresentada no documento BR PI0500338-5 que descreve a utilizagao de uma biela constituida por diversas hastes longitudinals de segao transversal delgada dispostas Iado a Iado ao Iongo do eixo geometrico da haste de acionamento, conferindo ao conjunto flexibilidade transversal e rigidez axial. Ocorre, no entantoT que essa solugao envolve um processo construtivo e de montagem complexo que pode onerar significativamente os custos finals do equipamento. Ja ο documento JP61274171 preve uma biela fabricada em resina flexivel sintetica que, apesar de ser capaz de absorver parte dos esforgos solicitantes, pode apresentar rigidez axial abaixo da adequada para operagao em compressores de alta frequencia e, com isso, comprometer a eficiencia do processo.In view of such operating conditions, some technical solutions have been developed with a view to eliminating the mentioned problems, such as that presented in the document BR PI0500338-5 which describes the use of a connecting rod consisting of several longitudinal cross-sectional rods. Slenderly arranged Side to side of the drive shaft geometry axis, giving the joint transverse flexibility and axial stiffness. It turns out, however, that this solution involves a complex construction and assembly process that can significantly incur the final equipment costs. JP61274171 already provides for a connecting rod made of synthetic flexible resin which, although capable of absorbing part of the stresses, may exhibit axial stiffness below that suitable for operation in high frequency compressors and thus compromise process efficiency.
O documento US2008/0019852，por sua vez, descreve uma biela rigida que se interliga a haste do elemento oscilador por meio de barras flexiveis delgadas IocaIizadas nas extremidades de uma "haste de transla^ao" destinada a favorecer a rotapao do eixo axial do pistao em relagao ao eixo axial da outra extremidade onde a biela esta fixa, bem como para reduzir a rigidez transversal da pega. Porem, de forma analoga a da citagao anterior, ο conjunto de barras flexiveis e haste de translagao pode comprometer a adequada eficiencia do compressor durante a opera^ao em frequencias elevadas. Ademais a construgao envolvendo materials distintos torna-se complexa e onerosa.US2008 / 0019852 ， in turn describes a rigid connecting rod that interconnects the oscillating member rod by means of thin flexible bars positioned at the ends of a "translation rod" designed to favor rotation of the axial axis of the piston. relative to the axial axis of the other end to which the connecting rod is attached, as well as to reduce the transverse stiffness of the handle. However, analogously to the above, the set of flexible rods and translation rod may compromise the proper efficiency of the compressor during operation at high frequencies. In addition the construction involving different materials becomes complex and costly.
Cite-se tambem ο documento US3801167 que descreve a utilizagao de uma biela dita flexivel de segao transversal uniforme que se conecta a um pistao-guia ο qual, por sua vez, e solidario a uma haste intermediaria de segao medial delgada com extremidade oposta fixa ao pistao de trabalho do compressor Tal haste intermediaria, no entanto, atua apenas como elemento de Iigagao entre ο guia de pistao e. ο pistao do equipamento e, portanto, nao exerce a fungao de biela como ocorre com ο objeto da presente invengao.Also cited is US3801167 which describes the use of a so-called flexible uniform cross-sectional connecting rod that connects to a guide rod which, in turn, is integral with a slender medial segment intermediate rod attached to the opposite end. compressor working runway Such an intermediate rod, however, acts only as a connecting element between the runway guide and. It is the equipment piston and, therefore, does not perform the function of connecting rod as occurs with the object of the present invention.
Em suma, percebe-se que ο atua丨 estado da tecnica carece de uma solugao deIn short, it is clear that the state of the art needs a solution

A Figura 1 mostra um corte transversal do mecanismo movel de um compressor linear no qual se pode observar um pistao 1 preso, por meio da haste ou biela 3 objeto da presente invengao, a uma das extremidades 21 de um elemento resiliente 2 (que, no caso， trata-se de uma mola ressonante), cuja extremidade oposta 22 acopla-se a um elemento 6 para fixagao do ima do motor 7.Figure 1 shows a cross-sectional view of the moving mechanism of a linear compressor in which a piston 1 secured by the rod or connecting rod 3 of the present invention to one end 21 of a resilient element 2 (which, in the case ， it is a resonant spring) whose opposite end 22 is coupled to an element 6 for fixing the motor magnet 7.
A haste ou biela para compressor linear em questao e definida por uma haste alongada 3 fabricada, preferencialmente, em ago ou titanio — ou Iigas metalicas contendo esses materials, que apresentam elevada resistencia a fadiga — ou outros material's de caracteristicas similares.The rod or connecting rod for the linear compressor in question is defined by an elongated rod 3, preferably made of steel or titanium - or metal alloys containing such materials, which exhibit high fatigue strength - or other materials of similar characteristics.
Conforme pode ser observado nas figuras anexas, a haste alongada 3 que constitui uma biela para compressor linear apresenta pelo menos duas regioes 4 com segao transversal aumentada, sendo que na concretizagao preferencial da presente invengao ambas as extremidades da haste alongada 3 apresentam tal eleva^io diametral, visando aumentar a area de fixagao da haste 3 a pega com a qual sera cooperante - no caso, a superficie do pistao 1 e a extremidade 21 do elemento resiliente 2.As can be seen from the accompanying figures, the elongate rod 3 constituting a linear compressor rod has at least two regions 4 with increased transverse section, and in the preferred embodiment of the present invention both ends of the elongate rod 3 exhibit such elevation. to increase the fixing area of the rod 3 the handle with which it will be cooperating - in this case the surface of the piston 1 and the end 21 of the resilient element 2.
As Figuras 2 e 3 ilustram uma outra possibilidade construtiva para a haste 3 em questão, na qual a peça é provida de uma região mediai 41 de seção transversal aumentada - que também pode ser chamada de "gomo central" - para aumentar a resistência à flambagem e facilitar o processo de fabricação. Afacilidade de fabricação vem do fato que o gomo central serve como um terceiro apoio para a ferramenta que faz o desbaste da região de seção transversal reduzida 5, sendo os outros dois apoios as duas regiões 4 com seção transversal aumentada.Figures 2 and 3 illustrate another constructive possibility for the rod 3 in question, in which the part is provided with an enlarged cross-sectional middle region 41 - which may also be referred to as a "center bud" - to increase buckling resistance. and facilitate the manufacturing process. The ease of manufacture comes from the fact that the center knuckle serves as a third support for the tool that roughs the reduced cross-sectional region 5, the other two supports being the two regions 4 with increased cross-section.
Em ambas as concretizações, a haste alongada 3 apresenta regiões mediais 5 de seção transversal reduzida que conferem flexibilidade transversal à peça. Neste aspecto, vale ressaltar que o material utilizado em sua confecção - preferencialmente aço ou titânio, conforme o mencionado - permitem que a haste 3 apresente certa flexibilidade transversal sem que isso acarrete em elevado risco de rompimento da peça ou redução de sua vida útil, uma vez que tais materiais apresentam elevada resistência à fadiga.In both embodiments, the elongate rod 3 has medial regions 5 of reduced cross section which impart transverse flexibility to the part. In this respect, it is noteworthy that the material used in its manufacture - preferably steel or titanium, as mentioned - allows the rod 3 to present some transverse flexibility without this leading to a high risk of rupture of the part or reduction of its useful life. since such materials have high fatigue strength.
Nas Figuras 2 e 3, a haste alongada 3 possui três regiões 4 e 41 de seção transversal aumentada e duas regiões mediais 5 de seção transversal reduzida; no entanto a quantidade de regiões 4 e/ou 5 da haste alongada 3 construída segundo uma das concretizações preferenciais da presente invenção pode variar sem que, com isso, se fuja do escopo da proteção reivindicada.In Figures 2 and 3, elongate stem 3 has three regions 4 and 41 of increased cross section and two medial regions 5 of reduced cross section; however, the amount of regions 4 and / or 5 of the elongate rod 3 constructed in one of the preferred embodiments of the present invention may vary without thereby departing from the scope of the claimed protection.
Já as Figuras 4 e 5 ilustram uma haste 3 mais curta cuja utilização pode ser necessária em equipamentos que apresentem restrições de espaço para montagem. Nesse caso, a haste 3 não apresenta regiões mediais 41 de seção transversal aumentada. Cabe esclarecer que nesta configuração com apenas uma região mediai 5 (que, portanto, configura uma peça mais curta que o convencional) a resistência à flambagem é obtida através do comprimento reduzido. Como esse encurtamento resulta em um aumento de rigidez transversal, o material mais recomendado para tais casos é o titânio devido ao seu menor grau de elasticidade quando em comparação com o aço.Figures 4 and 5 illustrate a shorter rod 3 which may be required for use in equipment with limited mounting space. In this case, rod 3 does not have medial regions 41 of increased cross section. It should be noted that in this configuration with only one middle region 5 (which therefore configures a shorter part than the conventional one) the buckling resistance is obtained through the reduced length. As this shortening results in increased transverse stiffness, the most recommended material for such cases is titanium due to its lower degree of elasticity when compared to steel.
Uma importante característica da haste ou biela 3 objeto da presente invenção refere-se ao fato de ser constituída por um corpo inteiriço e totalmente fabricado em um único material ou liga metálica, o que torna seu processo de produção e montagem muito mais simples que o observado com a utilização dos similares conhecidos - que não raramente envolvem diversos trechos de materiais distintos unidos entre si por processos de união quaisquer que, ademais, acabam por introduzir na peça final pontos de fragilidade capazes de comprometera eficiência e confiabilidade do equipamento.An important feature of the rod or connecting rod 3 object of the present invention is that it is made up of a one-piece body and completely made of a single material or alloy, which makes its production and assembly process much simpler than observed. with the use of similar ones - which not infrequently involve several sections of different materials joined together by any joining processes which, furthermore, end up introducing fragility points in the final piece capable of compromising the efficiency and reliability of the equipment.
Em suma, a presente invenção diz respeito a meios para possibilitar que uma haste alongada ou biela 3 possa ser utilizada em compressores lineares de alta freqüência apresentando, simultaneamente em uma peça inteiriça, grande rigidez axial, grande resis- tência a flambagem e baixa rigidez transversal.In summary, the present invention relates to means for enabling an elongate rod or connecting rod 3 to be used in high frequency linear compressors having, simultaneously in one piece, high axial stiffness, high buckling resistance and low transverse stiffness. .
Cabe salientar que embora tenham sido mostradas formas construtivas preferenciais da presente invenção, fica entendido que eventuais omissões, substituições e alterações construtivas podem ser feitas por um técnico versado no assunto, sem se afastar do espírito e escopo da proteção requerida. É também expressamente previsto que todas as combinações dos elementos que desempenham a mesma função substancialmente da mesma forma para alcançar os mesmos resultados estão dentro do escopo da invenção. Substituições de elementos de uma modalidade descrita por outros são também totalmente pretendidos e contempladosIt is to be noted that although preferred embodiments of the present invention have been shown, it is understood that any omissions, substitutions and constructive alterations may be made by one of ordinary skill in the art without departing from the spirit and scope of the protection required. It is also expressly provided that all combinations of elements that perform the same function in substantially the same way to achieve the same results are within the scope of the invention.
