Abstract: O PRESENTE INVENTO TEM COMO BASE UM PROTÓTIPO DE UMA FERRAMENTA PARA APLICAR A UM EQUIPAMENTO DE PRODUÇÃO DE VASSOURAS, ESCOVAS (DE USO DOMÉSTICO, PESSOAL E INDUSTRIAL), ESFREGONAS E ARTIGOS DE WC, E NOVAS GAMAS DE PRODUTOS DE ESCOVARIA. ESTA NOVA PEÇA PARA O EQUIPAMENTO, EM DUAS VERSÕES, CONSISTE NA JUNÇÃO DAS BASES DOS APERTOS, COM OS APERTOS PROPRIAMENTE DITOS (3). COM ESTA JUNÇÃO DAS REFERIDAS PEÇAS É POSSÍVEL ELIMINAR QUATRO PARAFUSOS EM CADA BASE, O QUE PERMITE ELIMINAR VINTE E QUATRO PARAFUSOS NO EQUIPAMENTO, TORNANDO-O MAIS EFICAZ, TENDO-SE SIMULTÂNEAMENTE REDUZIDO O TEMPO DE FIXAÇÃO DA MESMA CRIANDO UM NOVO SISTEMA DE APERTO QUE TIVESSE COMO MODO DE FIXAÇÃO UM SISTEMA DE PORCA EM SUBSTITUIÇÃO DO SISTEMA DE PARAFUSO. FOI CRIADO UM VEIO ROSCADO QUE UNISSE O APERTO AO EQUIPAMENTO E QUE FOSSE FIXADO ATRAVÉS DE UMA PORCA. ESTE SISTEMA DE FIXAÇÃO PROJECTADO TEM COMO PRINCIPAL VANTAGEM O FACTO DE NÃO SER NECESSÁRIO O USO DE FERRAMENTAS COMPLEXAS, VISTO QUE O VEIO ROSCADO COLOCADO NO EQUIPAMENTO NÃO NECESSITA DE SER SUBSTITUÍDO QUANDO É NECESSÁRIO TROCAR OS APERTOS. OUTRA VANTAGEM ADVÉM DO USO DE PORCAS DE APERTO RÁPIDO, QUE PODEM SER APERTADAS SEM O RECURSO A QUALQUER FERRAMENTA, O QUE TORNA O PROCESSO BASTANTE RÁPIDO. A ELIMINAÇÃO DA OPERAÇÃO DE ''AFINAÇÃO DO CURSO DOS APERTOS'' PASSOU POR COLOCAR OS APERTOS NA POSIÇÃO USADA PARA A PRODUÇÃO DOS PRODUTOS COM MAIORES DIMENSÕES. DESTE MODO A POSIÇÃO DOS APERTOS SERÁ SEMPRE A MESMA. PARA A PRODUÇÃO DE PRODUTOS DE MENORES DIMENSÕES, SERÃO CONSTRUÍDOS APERTOS COM MAIS ESPESSURA PARA COMPENSAR A DIFERENÇA ENTRE OS PRODUTOS DE MAIORES E MENORES DIMENSÕES.

Abstract: FIELD: electric engineering. SUBSTANCE: rotating electric machines are usually cooled with filtered air through fans 15, which are located on rotor shaft. This is achieved by means of cooling channels to stator and rotor and device air hole 22. If air which is taken from atmosphere contains harmful materials, filtered air is directly directed to stator and device air hole, but filtered air which is directed to rotor is subjected to additional filtration in filter which contains activated coal 30. Filtered cooled air which is directed to stator and, if necessary, to device air hole, is driven by fans, but air which is directed to rotor is directed through another path. This results in possibility to cool rotor by air which is driven by rotation of rotor. EFFECT: decreased cost on additional filters due to additional filtration of only small fraction of required air. 1 dwg
