Abstract

"CABEçA ROLANTE PARA UM SOLDADOR DE RESISTêNCIA ELéTRICA". Uma cabeça rolante (1) para uma máquina de soldagem de costura de resistência, compreendendo um estator (2); um eletrodo anular constituindo o rotor (3) rotativamente montado no estator (2); um dispositivo (4) para condução eletricamente através de um contato deslizante, posicionado entre o estator (2) e o rotor (3), e pressionado em direção axial contra pelo menos um deles por uma força elástica; e condutos (5a, 5b, 6, 7) através dos quais um refrigerante escoa no estator (2), no rotor (3) e no dispositivo condutivo de contato deslizante (4). O dispositivo condutivo elétrico (4) compreende elementos elasticamente de produção (8) formando um setor de efeito radial, moldado e/ou produzido em vários modos diferentes, posicionado entre o estator (2) e o rotor (3), e designado para permanecer permanentemente em contato com o estator (2) e o rotor (3), de modo a conduzir corrente elétrica de um para o outro.
