在三座标测量机中,为减小运动副的摩擦与磨损,一般认为采用气浮静压导轨比采用滚珠轴承更好。本文介绍了我所研制的SZC-1065型测量机上应用全气浮式花岗石静压导轨的情况。文中对气垫结构设计,节流孔的选择,气源压力、大小的选择进行了分析,并详细介绍了实验研究的情况和试验结果。
In the three coordinate measuring machine, in order to reduce the friction and wear pairs, generally considered the use of aerostatic guide rail ball bearing is better than the use of. This article describes the SZC-1065-type measuring machine developed by me and applied to all-weather floating granite hydrostatic guideway. In this paper, the design of air cushion, the choice of orifice, the selection of air pressure and size are analyzed. The experimental research and experimental results are introduced in detail.
