Description
"DISPOSIÇÃO CONSTRUTIVA INTRODUZIDA EM ANEL PARA FIXAÇÃO DE ROLAMENTO COM ORIFÍCIO PARA EXPURGO DE LUBRIFICANTE" "CONSTRUCTIVE ARRANGEMENT INTRODUCED IN RING FOR FIXING BEARINGS WITH LUBRICANT EXPURGE"
CAMPO DE APLICAÇÃO APPLICATION FIELD
[001] O presente modelo consiste em um anel para fixação de rolamento utilizado em máquinas elétricas girantes, sendo este fundido com orifício para expurgo do lubrificante. Este anel fundido é produzido sem a utilização de macho de fundição e sem qualquer processo de usinagem, gerando uma redução significativa nos custos de produção . [001] The present model consists of a bearing retaining ring used in rotating electric machines, which is cast with a lubricant purge hole. This cast ring is produced without the use of a casting core and without any machining process, resulting in a significant reduction in production costs.
FUNDAMENTOS DO MODELO MODEL GROUNDS
[002] Nos processos de fundição, as operações críticas se referem de maneira geral, à produção dos moldes e dos machos. Esta última consiste na obtenção de machos, normalmente feitos a partir de materiais refratários em uma área destinada exclusivamente para tal processo, e sua adição nos moldes, visando a formação de cavidades, furos e reentrâncias das peças. Uma vez montados os machos nos moldes, o conjunto de moldes está apto a receber a operação de vazamento do metal e assim formar o produto final. [002] In casting processes, critical operations generally refer to the production of molds and cores. The latter consists in obtaining cores, usually made from refractory materials in an area intended exclusively for such process, and their addition in the molds, aiming at the formation of cavities, holes and recesses of the parts. Once the cores are assembled into the molds, the mold assembly is able to receive the casting operation of the metal and thus form the final product.
[003] As principais desvantagens pertinentes à macharia residem nas variáveis introduzidas na especificação do projeto, como a possibilidade de sopros e formação de bolhas devido à remoção de gases inadequada, ou em situações mais extremas, a expulsão do metal líquido do interior dos moldes. Outro fator relevante vem a ser o posicionamento correto dos elementos que compõem o molde e o macho. A ausência de um
controle adequado nesta etapa pode acarretar em desvios dimensionais para valores além das normas de tolerância e como agravante, qualquer montagem entre componentes haverá desalinhamento e irregularidade entre as superfícies, comprometendo a qualidade do produto, pois não haverá garantia de que o mesmo será perfeitamente vedado, ocasionando a entrada de contaminantes, como por exemplo pó e água, no interior do produto. A atenção a todas estas variáveis acabam por encarecer o custo global do processo, impactando na automatização da linha de produção dos componentes fundidos. [003] The main disadvantages pertinent to the maschery lie in the variables introduced in the design specification, such as the possibility of blows and blistering due to improper gas removal, or in more extreme situations, the expulsion of liquid metal from the interior of the molds. Another relevant factor is the correct positioning of the elements that make up the mold and the core. The absence of a Proper control at this stage can lead to dimensional deviations beyond tolerance standards and as aggravating, any assembly between components will cause misalignment and irregularity between surfaces, compromising product quality, as there will be no guarantee that it will be perfectly sealed, causing contaminants such as dust and water to enter the product. Attention to all these variables ultimately increases the overall cost of the process, impacting the automation of the cast components production line.

Normalmente o expurgo do lubrificante é realizado pelo anel de fixação do rolamento, necessitando a aplicação de machos de fundição para a obtenção do orifício por onde ocorre o expurgo do lubrificante. Em casos onde o expurgo do lubrificante ocorre na tampa da máquina elétrica, o orifício de expurgo normalmente é produzido por algum tipo de processo de usinagem. State-of-the-art rotating electric machines with bearing fastening rings, specifically with cast iron rings, are usually produced in three parts, two molds of sand suitable for casting using a two-piece model. parts and a third part, traditionally being a foundry male. Normally the lubricant purge is performed by the bearing fixing ring, requiring the application of casting taps to obtain the hole through which the lubricant purge occurs. In cases where lubricant purging occurs on the electrical machine cover, the purging hole is usually produced by some type of machining process.
[005] Para o ótimo funcionamento da maioria das máquinas elétricas girantes, é necessária a utilização de um sistema de lubrificação dos rolamentos, compreendendo pelo menos um orifício de entrada para o lubrificante novo, podendo ser localizado na tampa ou no anel de fixação do rolamento, e pelo menos um orifício de saída do lubrificante deteriorado, podendo
ser localizado na tampa ou no anel de fixação do rolamento. Tal configuração de circuito de lubrificação permite que os rolamentos recebam periodicamente novo lubrificante e operem em ambiente adequado, conforme orientação dos fabricantes dos rolamentos. É de conhecimento para os versados na técnica que a correta lubrificação dos rolamentos está intimamente associada à sua expectativa de vida e consequentemente à vida operacional da máquina . [005] For optimum operation of most rotating electric machines, a bearing lubrication system is required, comprising at least one inlet hole for new lubricant and can be located on the bearing cap or locking ring , and at least one deteriorated lubricant outlet port, which may be be located on the bearing cap or mounting ring. Such a lubrication circuit configuration allows bearings to periodically receive new lubricant and operate in a suitable environment as directed by the bearing manufacturers. It is well known to those skilled in the art that the correct lubrication of the bearings is closely associated with their life expectancy and hence the operating life of the machine.
