Abstract

estrutura de vedação de extremidade de eixo e misturador de concreto provido com a mesma. são fornecidos uma estrutura de vedação da extremidade do eixo e um misturador de concreto provido com a mesma (estrutura). a estrutura de vedação da extremidade do eixo contém: um anel resistente ao desgaste (31) ligado a uma parede do reservatório de mistura (30) do misturador de concreto; uma tampa de proteção contra poeira (32) ligada ao eixo principal (21) do misturador de concreto que gira com eixo principal sincronizadamente; um primeiro espaço (34) formado entre a tampa de proteção contra poesia (32) e o anel resistente ao desgate (31) e comunicado com a cavidade de óleo de lubrificação; um anel de vedação (33) e o eixo principal (21) para constituir uma vedação em labirinto e comunicada com o primeiro espaço (34). a estrutura consegue evitar a lama de penetrar diretamente no circuito de óleo e vazar para o exterior, de modo a melhorar a vedação e confiabilidade da estrutura.
