摘要
在微尺度条件下,为了实现超高能量密度的目标,PowerMEMS通常要求其轴承转速达到106 r/min数量级以上,于是提出了微尺度超高转速气体动力润滑轴承的研究。论述了气体动力润滑轴承的微尺度结构特征,提出了PowerMEMS气体动压径向轴承承载能力的验算方法,分析了微尺度条件下气体动压径向轴承结构参数对轴承承载能力的影响。
Micro bearings of Power MEMS are usually designed to work at an ultra high speed more than 10^(6) r/min in order to improve their specific energy. So the dynamic lubrication of micro gas bearings at an ultra speed is researched. First the micro structural characteristics of micro gas-lubricated bearings are investigated, and a method to caculate the load-carrying performance of micro dynamic gas-lubricated bearings is put forword. Then the designs of two typical micro dynamic gas-lubricated bearings that are used in micro gas turbines are vertified. Moreover, the parameters affecting the load-carrying performance of micro dynamic gas-lubricated bearings are analysed.
