Abstract
<B>CONJUNTO INTEGRADO DE VENTOINHA COM PáS DE PASSO VARIáVEL<D>. Um conjunto de ventoinha (10) inclui primeira e segunda seções de alojamento (70, 72) que, quando encaixadas por um primeiro conjunto de prendedores, definem uma pluralidade de aberturas cirunferencialmente espaçadas (162) que conduzem a uma câmara de alojamento interna (82). O conjunto de ventoinha (10) também inclui uma pluralidade de unidade de pá (140), cada uma das quais inclui uma haste de suporte integral (142) tendo uma porção de munhão (148) montada giratoriamente em uma abertura respectiva das aberturas (162), uma porção de flange ampliada (144) e uma porção de montante radial (138) sustentadas giratoriamente por um elemento de cubo (106) dentro da câmara interna (82). Cada unidade de pá (140) tem preferivelmente um mancal de empuxo (156), manga de bucha (158) e pá de ventoinha (152) integrados à haste de suporte (142), com a pá de ventoinha (152) sendo moldada, preferivelmente, na haste de suporte (142) após posicionamento do mancal de empuxo (156) e manga de bucha (158) para formar um componente integral. O conjunto de ventoinha (10) inclui ainda um elemento acionador (112) que é sustentado movelmente na câmara de alohamento interna (82) e que é adaptado para engatar um pino (166) da haste de suporte (142) em uma posição descentrada de um eixo rotacional da mesma para ajustar o passo das pás da ventoinha (152). O conjunto de ventoinha (10) é adaptado para ser fixado a um dispositivo de acionamento (12) com uma porção (42) do dispositivo de acionamento (12) cobrindo um primeiro conjunto de prendedores (78) de tal modo que as primeira e segunda seções de alojamento (70, 72) possam ser apenas desmontadas após desprendimento do dispositivo de acionamento (120. Um arranjo detector (58, 180) também é fornecido, preferivelmente, para gerar sinais indicativos de pelo menos um dentro passo e velocidade de rotação das pás da ventoinha (152).
