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.shaft end sealing structure and concrete mixer provided with it. a shaft end sealing structure and a concrete mixer provided therewith (frame) are provided. the shaft end sealing structure contains: a wear resistant ring (31) attached to a wall of the concrete mixer mixing tank (30); a dust cover (32) connected to the mainshaft (21) of the concrete mixer which rotates with mainshaft synchronously; a first space (34) formed between the poetry cover (32) and the wear resistant ring (31) and communicated with the lubricating oil cavity; a sealing ring (33) and the mainshaft (21) to constitute a labyrinth seal and communicated with the first space (34). The structure can prevent sludge from penetrating directly into the oil circuit and leaking outwards to improve the sealing and reliability of the structure.
