摘　　要：多年来,在机床工业中存在放弃使用污染环境的冷却剂而采用干加工的倾向.为了从设计的角度考虑这一发展趋势,研究了非接触式密封系统的封尘性能.斯图加特大学机械零件研究所在一个为期4年的研究项目框架中积累了有关微尘密封的知识,并将它们转化成实用的设计准则.这种密封系统的工作性能利用颗粒计算器通过实验的方法得到证实.正确设计的带气阻辅助装置的非接触式密封系统适用于在高速主轴中安全、可靠、持续地进行防微和细颗粒密封.In these several years, there exists a trend of adopting dry processing instead of cooling lubricant which will trigger environmental pollution in machining tool industry. To consider this trend from the perspective of design, a non-contact air barrier sealing arrangement was proposed. In the Mechanical Part Institute of the University of Stuttgart, knowledge of dust particles sealing was accumulated in the framework of a four-year research project, and this knowledge was transformed to practical design rules. The performance of this sealing system was validated through experimental method by adopting particle analyzer. The correctly designed non-contact air barrier sealing system can be applied in safely, reliably and continuously preventing highspeed rotating shaft from dusts and particles.
