大功率空气静压轴承电主轴

High Frequency Electric Spindle with High Power and Static Pressure Air Bearing

介绍自行研究设计的空气静压轴承高频电主轴设计上的特点 :一是空气轴承采用“全支承”结构 ,显著地提高轴承的承载能力和刚度 ;二是较国内同类型产品其变频电机的输出功率显著增大 。

The series of static pressure air bearing high frequency electric spindle is one of the hi-tech products in the 21st century.This product replaces ball bearings which are used in traditional high-speed grinding tools with air bearing.There are 2 features in its design:first,the all round bearing structure adopted by air bearing improving the load capacity and stiffness of the bearing greatly;second,compared with the same frequency products at home,the power of alterable frequency electrical motor is much higher,which meets to the requirements from high-efficiency grinding processes.
