磁流体滑动轴承
摘要：
本发明提供了一种磁流体滑动轴承，包括：锥形轴承内套、轴承外套、第一旋转轴唇形密封圈、第二旋转轴唇形密封圈以及线圈，所述锥形轴承内套内嵌在所述轴承外套内部，所述锥形轴承内套的内环面与转轴固定，所述锥形轴承内套的外环面与所述轴承外套的内环面之间构成环形密闭空间，所述环形密闭空间中充盈有磁流体；所述第一旋转轴唇形密封圈、第二旋转轴唇形密封圈分别密封轴承外套与锥形轴承内套匹配连接的两个端面；所述线圈缠绕在所述轴承外套外环面上的多个环形凹槽内。本发明中的磁流体滑动轴承能够获得更大的承载力，且可同时承受轴向力和径向力，并在轴向上具有一定的止推作用。
摘要（英）：

The invention provides a magnetofluid slide bearing. The magnetofluid slide bearing comprises a conical bearing inner sleeve, a bearing outer sleeve, a first rotating shaft lip-shaped sealing ring, asecond rotating shaft lip-shaped sealing ring and coils; the conical bearing inner sleeve is embedded in the bearing outer sleeve; an inner ring surface of the conical bearing inner sleeve is fixed with a rotating shaft; closed space is formed between an outer ring surface of the conical bearing inner sleeve and an inner ring surface of the bearing outer sleeve, and is filled with a magnetofluid;the first rotating shaft lip-shaped sealing ring and the second rotating shaft lip-shaped sealing ring respectively seal two matched and connected end surfaces of the bearing outer sleeve and the conical bearing inner sleeve; and the coils are wound in multiple annular grooves in an outer ring surface of the bearing outer sleeve. The magnetofluid slide bearing can achieve higher bearing force, cansynchronously bear axial force and radial force, and achieves a certain thrust effect in the axial direction.
