Abstract

本发明的单环反向互套轴向磁悬浮轴承是由大磁环(1)，小磁环(2)，主轴(3)等。大磁环(1)套在小磁环(2)的外侧。大磁环(1)产生的内侧的永磁波与小磁环(2)产生的外侧的永磁波极性相反。此时大磁环(1)会对小磁环(2)同时产生轴向径向吸引力，小磁环(2)会自动处于大磁环(1)的轴向中间位置。

Description

单环反向互套轴向磁悬浮轴承
所属技术领域
本发明涉及一种单环反向互套轴向磁悬浮轴承，该轴承是在轴向充磁大磁环内侧套一个轴向充磁小磁环，大磁环与小磁环的极性相反。实现大磁环对小磁环的径向轴向相吸。属于磁悬浮技术领域。
背景技术
目前，轴向永磁悬浮的主要办法是用两个磁环同极相对相互挤压，用一个磁环的端面磁场顶推另外一个磁环同极端面磁场，实现轴向悬浮。但是由于磁环端面磁场密度比较低。所以端面相互挤压实现轴向悬浮时，其效率比较低。
发明内容
本发明的原理是利用轴向充磁大磁环套一个轴向充磁小磁环，大磁环与小磁环极性相反。这样大磁环内侧的高密度轴向磁力线就能够对小磁环外侧的反向轴向磁力线产生相吸力。这样小磁环就能获得较大的轴向吸力，这种轴向吸力就能够成为轴向悬浮力。
附图说明
图1是本发明的单环反向互套轴向磁悬浮轴承的径向剖面构造图。
下面结合附图对本发明做进一步说明。
图1中，大磁环(1)，小磁环(2)，主轴(3)等。大磁环(1)套在小磁环(2)的外侧。大磁环(1)产生的内侧的永磁波与小磁环(2)产生的外侧的永磁波极性相反。此时大磁环(1)会对小磁环(2)同时产生轴向径向吸引力，小磁环(2)会自动处于大磁环(1)的轴向中间位置。
