Abstract

"COMPRESSOR DO TIPO CARACOL". O desempenho de um compressor e a durabilidade de corpos em caracol são melhorados pela otimização do alívio para tolerância de usinagem em uma parte final central dos membros em espiral para a formação de corpos em caracol. Em um compressor tipo caracol, no qual uma porção reforçada (por exemplo, um grande raio de curvatura R), mais reforçada do que em outras porções de canto de raiz 5, é provida em uma porção de canto de raiz 5 em uma parte final central na qual uma tensão dos dois membros em espiral 10 e 20 é elevada, um primeiro alívio é formado em uma região na qual os dois membros em espiral 10 e 20 entram em contato um com outro, onde a porção reforçada é aplicada apenas a um dos membros em espiral 10 e 20, e um segundo alívio, maior do que o primeiro, é provido em uma região na qual os dois membros em espiral entram em contato um com outro em uma porção na qual o raio de curvatura R é provido em ambos os membros em espiral, formamdo, desse modo, razoavelmente, alívios para evitar a interferência no ponto de contato dos dois membros em espiral.
