在超精密气浮定位平台研究工作中,气浮轴承是基本单元,导轨滑架与气浮轴承的连接采用自准式定位结构,并且闭式导轨中辅助支撑一侧的气浮轴承安装支架串联蝶形弹簧,起到了间隙补偿的作用,有效的补偿了由于温度变化,加工、安装误差造成的气膜间隙变化,降低了加工要求,提高了导轨的性能。
在超精密氣浮定位平檯研究工作中,氣浮軸承是基本單元,導軌滑架與氣浮軸承的連接採用自準式定位結構,併且閉式導軌中輔助支撐一側的氣浮軸承安裝支架串聯蝶形彈簧,起到瞭間隙補償的作用,有效的補償瞭由于溫度變化,加工、安裝誤差造成的氣膜間隙變化,降低瞭加工要求,提高瞭導軌的性能。

In the ultra-precision aerostatic positioning stage research, aerostatic guideways with air bear-ing flotation rail unit, both sides of the air bearing guideways carriage have the auto collimator positioning con-nection structure, and one side of the air bearing mounting bracket with series butterfly spring, played the role of gas film gap compensation, compensating the gas film gap changes caused by temperature changes, processing, installation errors, reducing the processing requirements, improving the rail properties.
