电磁式磁浮机构轴承 技术领域
本发明涉及一种电磁式磁浮机构轴承 背景技术
目前现有的轴承当中 ， 其种类繁多 按其用途及规格等来细分， 约超过数万多种， 因此归类颇为不易 若依照轴承的机能及相对运动 的方式区分， 约可分为滚动轴承及滑动轴承二大类， 且滚动轴承与滑 动轴承各有其优缺点
滚动轴承与滑动轴承相比较， 其优点在于所产生的摩擦力较低、 润滑简单、 可同时承受径向与推力的负载 、 忍受超载、 可与转轴 接合， 使激活扭矩较小， 而且当轴径相当时， 其所占的轴向空间也较 少； 然而， 滚动轴承价格较高 、 噪音大 、 所需的径向空间较大、 使用 寿命短、 承受震动的能力较差 ， 而且在破坏前并无预警的迹象， 以至 于容易造成整体机构的损坏■··等， 则为滚动轴承的缺点。
另外， 滑动轴承主要使用于负荷重 、 速度低及有冲击性的机械， 而滚动轴承则大半用于负荷轻 、 速度快 、 精度高、 无冲击性的机械， 但是这二类轴承都是具有其限制性， 例如摩擦问题就无法避免， 摩擦 力不仅损耗能量及机件， 也会产生高温， 致使机件因高温而产生变形， 而影响其精度， 甚至破坏整个设备， 且速度愈高时， 该问题会愈严重， 而为解决摩擦问题， 通常会配合适当的润滑油来降低摩擦系数， 来达 到改善的 目 的， 然而， 使用润滑油会产生污染问题， 严重时甚至会影 响到整个轴承的运作， 而且也不利于环保。
再者， 传统接触性的轴承装置， 不论如何的加以改善， 都无法完 全消除摩擦现象， 以致机构零件会因摩擦产生微粒漂浮于其中， 无法 符合目前高科技产业的需求， 因此为了解决摩擦问题， 即有业者朝非 接触式轴承的方向进行研发。 而目前现有的非接触式轴承主要分为三类 -
1 .空气轴承：其缺点是负荷大时会造成精度较差， 难以控制， 且刚 性不.佳， 可承受力量较小。
2.流体轴承：其刚性髙， 可承受负荷大， 成本也不高， 但是流体阻 尼太大， 且容易受温度影响， 进而影响精度。
3.磁浮轴承：目前被认为最具发展潜力的非接触式轴承， 它是根据 磁力作用的原理， 以借着磁场感应产生的磁浮力， 将转轴悬浮起来， 使得定子与转子之间不会相互接触。
由上可知， 相较于其它非接触式轴承， 磁浮轴承确实拥有许多优 点 -
1 .无旋转阻力， 转轴的转速可远髙于其它轴承
2 .不需要复杂的润滑系统或气压系统。
3 .使用寿命长、 维修成本低。
4.无磨擦， 可避免因摩擦所产生的阻抗、 噪立
曰 以及污染问题。
5 .用于非常低温或髙寘空状态等特殊工作环境 (如外层空间等）。
6.过主动式控制提供所需的刚性， 并有效抑制因高速运转时所产 生的振动问题。
然而， 磁浮轴承虽有如此多优点， 然其亦有某些问题存在 其缺 点如下 -
1 .电流流经电磁铁时， 会因为电磁铁的磁场线圈的电阻而发热， 进而造成能量上的损耗。
2.磁性电感较低。

定子 1 与转子 2相对应的部份都为 N极， 利用同磁极相斥原理， 让定子 1 与转子 2之间形成间隙， 让转轴套设于本发明的电磁式磁浮 机构轴承上转动时， 因为定子 1与转子 2 的不相互接触， 进而达到无 摩擦、 无噪音及低耗能的 目的。 电磁铁 3上的磁极会因为电流控制器 6 的改变而有所不同， 且定子 1 与转子 2 两者电磁铁 3磁性最强的地 方， 即是尖端的部份， 也就是两者相对应的部份。
