Abstract
一种磁液双悬浮轴承,包括主轴(4)、定子(2)及转子(30),定子(2)的壳体(1)内设有径向磁极(18)、导磁套(12),径向磁极(18)成对设置,每个径向磁极(18)均设有径向线圈(33)、径向进油孔(15),径向磁极(18)的端部设置有不导磁多孔介质垫片;定子(2)的轴向还固定有轴向磁极(14),轴向磁极(14)成对设置,轴向磁极(14)上套有轴向线圈(9),转子(30)两侧的轴向磁极(14)分别与第一永磁体(13)和第二永磁体(35)形成磁通回路,永磁体(13,35)的外径侧设置有碳纤维包覆增强层;定子(2)轴向设有轴向进油孔(16)、轴向绕线孔(19),径向设有出油口(36)、径向绕线孔(11)。通过将径向磁液双悬浮轴承与轴向磁液双悬浮轴承结合成一体,缩短了整个磁液双悬浮***的轴向长度,可适用于狭小的空间,且减少了轴承的加工装配误差。
