Abstract
"MáQUINA DINAMOELéTRICA COM BARRAS DE ENROLAMENTO ENCRAVADAS". A presente invenção refere-se a uma máquina dinamoelétrica (20) dotada de barras de enrolamento (13) as quais são inseridas em cavas previstas para este propósito na máquina dinamoelétrica (20), sendo cada uma das cavas fechada por cunhas de tampa (23) e sendo previstas cunhas corrugadas (16) entre as cunhas de tampa (23) e as barras de enrolamento (13) localizadas por baixo delas, as quais são submetidas à pré-tensão por meio de cunhas opostas (21) que ficam dispostas entre as cunhas de tampa (23) e as barras de enrolamento (13) localizadas por baixo delas. Em uma máquina como esta, torna-se possível realizar encravamento rápido e simples pelo fato de que as cunhas opostas (21) ficam dispostas entre as cunhas de tampa (23) e as molas corrugadas (16), e em que são previstos elementos de ajustagem (22) de posição fixa, por meio dos quais é possível fazer-se variar a distância entre as cunhas de tampa (23) e as cunhas opostas (21).
