摘要
基于单元气体静压轴承的承载性能,简化多支承气体静压电主轴的支承和主轴结构,建立了有限元分析模型,借助ANSYS软件分析轴系的各种结构方案,并进行承载特性分析对比。研究分析多支承结构的承载机理,总结出提高气体静压电主轴承载特性的措施。分析了不同主轴结构和轴承布置对电主轴承载特性的影响,优选出了的多支承静压轴承电主轴结构。
The paper was based on load-- bearing properties of elementary aerostatic bearing, predigested support and spindle structure of multi--support aerostatic motorized spindle, established finite-element analysis model, analyzed all kinds of structureal designs of shafting refer to ANSYS software, analyzed and compared load--bearing characteristics. By studying and analyzing load--bearing mechanism of multi--support structure, the paper summarized out measures that was used to improve aerostatic motorized spindle load-bearing characteristics. The paper also analyzed that different spindle structures and bearing arrangements influenced load--bearing characteristics of motorized spindle, finally obtained excellent multi-support hydrostatic bearing motorized spindle structure.
