    Abstract: A magnetic fluid seal device that increases a permissible value of eccentricity for two members to improve sealability and decreases a variation of quality by injecting a magnetic fluid before assembling of parts, that saves structural members to achieve thinning, and that is easy to produce. An annular magnet (3) is held floating by magnetic fluid layers (4, 5) retained, and the space between a housing (1) and a shaft (2) is sealed by the annular magnet (3) and magnetic fluid layers (4, 5).

    Abstract translation: 一种磁性流体密封装置,其通过在组装零件之前注入磁性流体而增加两个构件的偏心度的允许值以提高密封性,并且通过在组装零件之前注入磁性流体来降低质量变化,从而节省结构构件以实现变薄,并且易于制造。 环形磁体(3)由保持的磁性流体层(4,5)保持浮动,壳体(1)和轴(2)之间的空间由环形磁体(3)和磁性流体层(4)密封 ,5)。
