Abstract

é descrita neste documento uma unidade de lâmina (10) para ventiladores industriais, a qual compreende: - uma lâmina; e - uma barra tubular (4), fixada na lâmina e a qual possui uma porção de base (4a) configurada para ser engatada através da conexão da barra com o rotor de um ventilador. a unidade é caracterizada pelo fato de compreender uma barra adicional (6) montada dentro da primeira barra tubular (4) de modo a apresentar uma primeira porção (6a) restringida axialmente à primeira barra, e uma segunda porção que é, ao invés disso, capaz de deslizar com relação à primeira barra, em uma condição de atrito por deslizamento, seguido por uma deformação devido à inclinação da primeira barra.
