摘要
径向轴承是划片机空气静压电主轴的关键零件,径向轴承的结构及尺寸直接影响转轴的高速旋转精度及工作性能。采用表压比法对划片机空气静压电主轴径向轴承进行设计计算,确定径向轴承的结构参数。
The journal bearing is the key part of the dicing saw＇s aerostatic motorized spindle. The journal bearing＇s structure and dimension infiuent indirectly on the spindle＇s rotating precision and working capacity at high speed. The journal beating of dicing saw＇s aerostatic motorized spindle are designed and calculated through gauge pressure ratio method, and the journal bearing＇s structural parameters are determined.
