Abstract

hélice sem carenagem para turbomáquina uma hélice sem carenagem de palhetas de passo variável, cujos pés (38) são engatados, cada um, a prtir do exterior, em um alojamento radial de um elemento anelar de motor e guiado em rotação em torno de seu eixo por dois de rolamento (76, 94), dos quais um é mantido por um segmento anelar (54) de saia cilíndrica (56) montado em uma garganta (50) do corpo cilíndrico (40) e por uma porca de bloqueio (64) aparafusada sobre a saia cilíndrica (56). dito mancal (94) é coberto exteriormente por um anel (100) que tem dentes de engate externos (108) que operam em conjunto com os dentes de engate internos (112) do ouse do alojamento para reter radialmente o anel (100) no alojamento. meios de bloqueio engatados entre os dentes (112) do alojamento e aqueles do anel (100) impedem a rotação do anel (100) e sua retirada axial do alojamento.
