【摘要】 空气动压箔片轴承是一种无油支承技术,没有接触摩擦,从根本上避免了滚动支承的润滑油"高温起雾"的难题,被认为是支承技术的一场革命。本文针对某离心风机对空气动压箔片轴承的需求,重点研究了轴承的设计、仿真计算、制造、表面涂层等技术,研制出了承载能力12.5kg的高速空气动压轴承,并对轴承性能进行了测试;同时,对高速大功率永磁电机及其控制技术进行了研究与开发,研制出了不同功率的多套样机;最后,将空气动压轴承、高速电机、风机叶轮等结合起来,设计制造了动压风机原理样机。更多还原

【Abstract】 Air foil bearings, which are oil-free support technology with negligible friction, can overcome many problems of rolling element bearings such as lubricant deterioration at high temperature, and bring a technological revolution in the high speed bearing field. To meet the requirements in centrifugal blower applications, air foil bearings with a load capacity of12.5kg were designed, manufactured and tested. A high speed and high power permanent magnet motor and its control technology were investigated, and a series of foil bearing-supported high speed blowers with different powers were designed and manufactured.更多还原
