摘要

軸承在我們的生活中隨處可見，而軸承也分為幾種不同的樣式，像是有滾珠軸承、氣動軸承核磁浮軸承，而各種軸承都有不同的特性，也使用在不同的地方，而隨著精密加工技術越來越發達，氣動軸承也逐漸取代其它軸承，而氣動軸承也會逐漸成為精密機械主要核心之一。氣動軸承因為摩擦小轉速高且震動低，所以氣動軸承都是用在精密儀器上，像是在電子廠、醫學、及精密機械工廠等，但是氣動軸承不能承受太大的負載力。本研究的研究是氣動軸承內部氣場穩流之狀態，是以CFD及研究方法來分析內部氣場之穩流狀態。

Bearing in our lives everywhere, while the bearing is also divided into several different styles, such as ball bearing, air bearing nuclear magnetic bearings, and all kinds of bearings has different characteristics, is also used in different places, and with the precision machining technology becomes more developed, pneumatic bearings are also gradually replace other bearings, bearings and air will gradually become one of the main core of precision machinery. Pneumatic bearing because friction is small, high speed and low vibration, the pneumatic bearings are used in precision instruments, such as in the electronics factory, medical, and precision machinery factories, but cannot withstand too much aerodynamic load bearing force. This research study is the internal state of the pneumatic bearing steady flow of the gas field, based on CFD and research methods to analyze the steady flow state of the internal gas market.
