Guia sobre a vida \u00fatil e a reten\u00e7\u00e3o do bin\u00e1rio das dobradi\u00e7as de bin\u00e1rio<\/a> para definir o objetivo do projeto e o m\u00e9todo de aceita\u00e7\u00e3o. Este artigo limita-se a comparar se cada fornecedor apresentou provas equivalentes em rela\u00e7\u00e3o a esse objetivo.<\/p>\n\n\n\nVerifique se a geometria de montagem permite que a dobradi\u00e7a transmita esse bin\u00e1rio na sua montagem<\/h2>\n\n\n\n O bin\u00e1rio do fornecedor \u00e9 normalmente medido num dispositivo de fixa\u00e7\u00e3o controlado. O seu equipamento pode utilizar chapa met\u00e1lica flex\u00edvel, sali\u00eancias moldadas, um suporte deslocado, duas dobradi\u00e7as amplamente espa\u00e7adas, um feixe de cabos, uma junta ou um painel que cede sob a for\u00e7a manual. Esses elementos podem alterar a for\u00e7a de abertura medida e a impress\u00e3o do utilizador relativamente \u00e0 dobradi\u00e7a, mesmo quando a pr\u00f3pria dobradi\u00e7a est\u00e1 em conformidade com a sua ficha t\u00e9cnica.<\/p>\n\n\n\n
Analise a interface mec\u00e2nica com o mesmo cuidado com que analisa o valor do bin\u00e1rio. A localiza\u00e7\u00e3o do eixo da dobradi\u00e7a, a orienta\u00e7\u00e3o da folha, o padr\u00e3o de orif\u00edcios, a espessura do suporte, o m\u00e9todo de fixa\u00e7\u00e3o e a rigidez local determinam se o bin\u00e1rio \u00e9 transformado em resist\u00eancia \u00fatil do painel ou se \u00e9 perdido devido \u00e0 flex\u00e3o, ao deslizamento e ao desalinhamento.<\/p>\n\n\n\nEspecifica\u00e7\u00f5es do fornecedor<\/th> Pergunta na Assembleia<\/th> A\u00e7\u00e3o necess\u00e1ria<\/th><\/tr><\/thead> Bin\u00e1rio medido num dispositivo de fixa\u00e7\u00e3o r\u00edgido<\/td> O painel ou o suporte de produ\u00e7\u00e3o ir\u00e3o ceder?<\/td> Teste a dobradi\u00e7a na estrutura de montagem final.<\/td><\/tr> Resultado da dobradi\u00e7a \u00fanica<\/td> Ser\u00e1 que duas dobradi\u00e7as distribuem o bin\u00e1rio de forma uniforme?<\/td> Me\u00e7a o funcionamento em par e verifique o alinhamento coaxial.<\/td><\/tr> Padr\u00e3o nominal de orif\u00edcios<\/td> Ser\u00e1 que as toler\u00e2ncias de fabrico provocam o desalinhamento da dobradi\u00e7a?<\/td> Sobrepor o desenho do fornecedor ao desenho da montagem aprovado.<\/td><\/tr> Movimento livre da dobradi\u00e7a<\/td> Os cabos, as juntas ou os batentes acrescentam uma carga dependente da dire\u00e7\u00e3o?<\/td> Realize o teste com o chicote el\u00e9trico definitivo, a junta e os limites de curso instalados.<\/td><\/tr> Curva de temperatura na bancada<\/td> O conjunto instalado funciona a outra temperatura?<\/td> Repita a verifica\u00e7\u00e3o funcional pertinente ap\u00f3s o condicionamento.<\/td><\/tr> Aceita\u00e7\u00e3o individual das dobradi\u00e7as<\/td> A incompatibilidade entre pares pode deformar o painel?<\/td> Definir limites de emparelhamento ou ao n\u00edvel do conjunto, sempre que necess\u00e1rio.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nQuando um fornecedor oferece v\u00e1rias vers\u00f5es de montagem do mesmo mecanismo interno, n\u00e3o se deve partir do princ\u00edpio de que s\u00e3o intercambi\u00e1veis. Uma altera\u00e7\u00e3o no suporte, no comprimento da l\u00e2mina, no apoio do eixo ou no desvio de montagem pode alterar a rigidez, a carga nos rolamentos, a toler\u00e2ncia de montagem e a forma como o utilizador aplica a for\u00e7a.<\/p>\n\n\n\n
Adaptar os materiais, o acabamento e o lubrificante ao ambiente de funcionamento<\/h2>\n\n\n\n Duas dobradi\u00e7as com curvas de bin\u00e1rio semelhantes podem apresentar riscos de funcionamento diferentes, uma vez que os seus materiais e sistemas de atrito interno reagem de forma diferente \u00e0 humidade, \u00e0 exposi\u00e7\u00e3o ao cloreto, aos produtos qu\u00edmicos de limpeza, ao p\u00f3, ao l\u00edquido de arrefecimento ou \u00e0 temperatura.<\/p>\n\n\n\n
Solicite informa\u00e7\u00f5es sobre o material e o acabamento de todo o percurso de bin\u00e1rio, e n\u00e3o apenas da parte vis\u00edvel da estrutura. A estrutura, o eixo, os elementos de atrito, as molas ou pe\u00e7as de pr\u00e9-carga, as buchas, os elementos de fixa\u00e7\u00e3o e o lubrificante podem n\u00e3o ser do mesmo material. Um exterior em a\u00e7o inoxid\u00e1vel n\u00e3o prova, por si s\u00f3, que todos os componentes funcionais sejam adequados ao ambiente.<\/p>\n\n\n\n

O fornecedor deve definir a constru\u00e7\u00e3o efetiva e apresentar provas relevantes para o projeto nos casos em que uma falha ambiental possa afetar o desempenho do material.<\/p>\n\n\n\n

A qualidade das evid\u00eancias tamb\u00e9m influencia a rapidez com que uma diferen\u00e7a t\u00e9cnica pode ser resolvida. Quando um fornecedor indica um bin\u00e1rio nominal mais baixo, mas fornece curvas completas e amostras rastre\u00e1veis, a equipa de engenharia pode determinar se a dobradi\u00e7a \u00e9 adequada para a aplica\u00e7\u00e3o. Quando outro fornecedor publica um valor mais elevado sem indicar quaisquer condi\u00e7\u00f5es, a equipa do projeto n\u00e3o consegue determinar se a vantagem aparente \u00e9 real.<\/p>\n\n\n\n
Entre as lacunas mais comuns nos dados de prova contam-se uma revis\u00e3o obsoleta do desenho, dados de bin\u00e1rio relativos a outro modelo, uma \u00fanica curva selecionada sem dispers\u00e3o da amostra, resultados de ciclos sem valores iniciais e finais e relat\u00f3rios que n\u00e3o podem ser associados ao lote de amostras apresentado.<\/p>\n\n\n\n<\/p>\n\n\n

Em primeiro lugar, \u00e9 necess\u00e1rio distinguir os requisitos obrigat\u00f3rios das vantagens comparativas. Uma dobradi\u00e7a que n\u00e3o cumpra os requisitos relativos ao intervalo de bin\u00e1rio, \u00e0 geometria, ao ambiente ou \u00e0 meta de reten\u00e7\u00e3o n\u00e3o deve passar \u00e0 fase seguinte apenas por ter obtido uma boa pontua\u00e7\u00e3o em \u00e1reas menos cr\u00edticas.<\/p>\n\n\n\n\u00c1rea de revis\u00e3o<\/th> Passar<\/th> Comparar<\/th> Aguardar<\/th><\/tr><\/thead> Defini\u00e7\u00e3o e condi\u00e7\u00f5es do bin\u00e1rio<\/td> Completo e diretamente compar\u00e1vel<\/td> Foi resolvida uma pequena diferen\u00e7a terminol\u00f3gica<\/td> O valor nominal n\u00e3o tem uma defini\u00e7\u00e3o estabelecida<\/td><\/tr> Comportamento torque-\u00e2ngulo<\/td> Toda a janela exigida encontra-se dentro do envelope de aceita\u00e7\u00e3o<\/td> A forma da curva difere, mas continua a ser aceit\u00e1vel<\/td> Falta uma curva ou o bin\u00e1rio local n\u00e3o cumpre os requisitos<\/td><\/tr> Toler\u00e2ncia e varia\u00e7\u00e3o da amostra<\/td> Os limites e os dados relativos a v\u00e1rias unidades corroboram a necessidade de produ\u00e7\u00e3o<\/td> A varia\u00e7\u00e3o \u00e9 aceit\u00e1vel, mas \u00e9 necess\u00e1rio apresentar mais provas concretas<\/td> O spread da amostra ou a incompatibilidade entre pares n\u00e3o est\u00e1 controlado(a)<\/td><\/tr> Reten\u00e7\u00e3o do ciclo<\/td> Os dados iniciais e finais est\u00e3o em conformidade com a metodologia do projeto<\/td> A evid\u00eancia \u00e9 relevante, mas est\u00e1 sujeita a uma condi\u00e7\u00e3o que requer confirma\u00e7\u00e3o<\/td> A contagem de ciclos \u00e9 apresentada sem o bin\u00e1rio retido<\/td><\/tr> Montagem e geometria<\/td> A interface de desenho e a de montagem s\u00e3o compat\u00edveis<\/td> Uma altera\u00e7\u00e3o menor na estrutura ou no padr\u00e3o dos orif\u00edcios \u00e9 f\u00e1cil de resolver<\/td> O conflito relativo ao eixo, ao inv\u00f3lucro, \u00e0 rigidez ou \u00e0 instala\u00e7\u00e3o n\u00e3o foi resolvido<\/td><\/tr> Material e ambiente<\/td> A constru\u00e7\u00e3o completa \u00e9 adequada \u00e0s condi\u00e7\u00f5es de funcionamento<\/td> S\u00e3o necess\u00e1rias provas ambientais adicionais<\/td> N\u00e3o est\u00e3o dispon\u00edveis informa\u00e7\u00f5es essenciais sobre o material ou o lubrificante<\/td><\/tr> Rastreabilidade<\/td> A amostra, o desenho, o relat\u00f3rio de ensaio e o lote est\u00e3o associados<\/td> As lacunas administrativas podem ser colmatadas antes da aprova\u00e7\u00e3o<\/td> As amostras enviadas n\u00e3o podem ser associadas aos dados comunicados<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nUtilize o Passar<\/strong> coluna para determinar se a dobradi\u00e7a pode prosseguir.

O mesmo valor nominal em N\u00b7m pode corresponder a comportamentos diferentes em termos de arranque, funcionamento, manuten\u00e7\u00e3o, abertura ou fecho.<\/p> <\/div>
Que toler\u00e2ncia de bin\u00e1rio devo exigir a um fornecedor de dobradi\u00e7as de bin\u00e1rio constante?<\/strong> N\u00e3o existe uma toler\u00e2ncia universal que se adapte a todas as aplica\u00e7\u00f5es. Defina os valores m\u00ednimo e m\u00e1ximo admiss\u00edveis com base nos requisitos de fixa\u00e7\u00e3o do painel, na for\u00e7a de opera\u00e7\u00e3o aceit\u00e1vel, no n\u00famero de dobradi\u00e7as, na varia\u00e7\u00e3o de produ\u00e7\u00e3o, na rigidez de montagem, na temperatura e na varia\u00e7\u00e3o de bin\u00e1rio prevista ao longo da vida \u00fatil.<\/p> <\/div>
O bin\u00e1rio de abertura e o bin\u00e1rio de fecho devem ser id\u00eanticos?<\/strong> N\u00e3o necessariamente. Algumas dobradi\u00e7as de bin\u00e1rio constante apresentam diferen\u00e7as direcionais devido \u00e0 geometria do atrito interno, \u00e0 pr\u00e9-carga, ao comportamento do lubrificante e \u00e0 dire\u00e7\u00e3o de montagem.

Quantas amostras dos fornecedores devem ser testadas?<\/strong> N\u00e3o existe uma quantidade de amostra universal para todos os projetos. Utilize unidades suficientes para identificar a varia\u00e7\u00e3o entre unidades e entre pares, tendo em conta o n\u00edvel de risco decorrente do equipamento, do volume de produ\u00e7\u00e3o, das consequ\u00eancias em termos de seguran\u00e7a e do processo do fornecedor. N\u00e3o baseie a aprova\u00e7\u00e3o da produ\u00e7\u00e3o numa \u00fanica amostra selecionada.<\/p> <\/div>
O que devo fazer quando um fornecedor apenas indica um valor de bin\u00e1rio no cat\u00e1logo?<\/strong> Utilize este valor apenas para uma triagem inicial. Solicite a defini\u00e7\u00e3o do bin\u00e1rio, a dire\u00e7\u00e3o, a janela angular, a velocidade, o tempo de perman\u00eancia, a temperatura, a toler\u00e2ncia, a rela\u00e7\u00e3o bin\u00e1rio-\u00e2ngulo, a varia\u00e7\u00e3o da amostra, os dados de reten\u00e7\u00e3o do ciclo, a revis\u00e3o do desenho e a rastreabilidade da amostra antes de efetuar uma compara\u00e7\u00e3o t\u00e9cnica.<\/p> <\/div> <\/div>","protected":false},"excerpt":{"rendered":"
