精密轴承在高速精密主轴设计中的应用

Application of Precise Bearing in Design for High Speed Precise Spindle

精密轴承是高速精密主轴设计中的关键零件之一。对高速精密轴承的选型与配置、高速精密轴承轴向限位方式、高速精密主轴轴承的预紧方式及其实现、高速精密轴承的润滑等关键技术问题进行了论述。对各种高速精密主轴设计具有参考价值。

The precise bearing is one of the key parts in design for high speed precise spindle. The key technical problems such as type selection and configuration for high speed precise bearing, the limit method of high speed precise bearing in the axial direction- al, the pre-tightening means of the high precise spindle bearing and its realization, the lubrication of the high speed precise bearing and so on, were discussed. It is of significant reference for different design of high speed precise spindle.
