Abstract
Patente de Invenção: <B>"ROTOR DE UMA MáQUINA ELéTRICA"<D>. Em um rotor de uma máquina elétrica, especialmente motor-gerador para usinas de reservatórios de bombeamento, o corpo de rotor (6), construído chapas metálicas em lâminas é retido em conjunto por meio de pinos tensores (8) que transcorrem axialmente, Em ranhuras na periferia externa do corpo de rotor é inserido o enrolamento de rotor (16) e ali retido contra ação da força centrífuga. As extremidades de enrolamento (16a), que saem axialmente do corpo de rotor, que formam o cabeçote de enrolamento (17), são seguras contra ação da força centrífuga por parafusos de pino (37) que transcorrem radialmente, os quais são atarraxados em uma disposição de anéis de apoio (19,...,24). A disposição de anéis de apoio abrange uma multiplicidade de anéis (19,...,24) distanciados na direção axial. Os anéis são conjuntamente tensionados, no segmento próximo ao eixo do corpo de rotor, conjuntamente com os dedos de aperto (30) com o pino de tração (8) que atravessa axialmente o corpo de rotor. No segmento afastado ao eixo estão previstos outros pinos de tração (25, 26, 27), os quais atravessam axialmente apenas a dita disposição de anéis e tensionam conjuntamente os anéis em direção axial.
