Dynamic Characteristics of an Externally Pressurized Conical Gas Bearing
외부가압 원추형 공기 베어링의 동특성에 관한 연구
Abstract
For excluding the effect of machining error such as perpendicularity, conical and spherical bearing has been used. In this paper, dynamic characteristics of the externally pressurized conical gas bearing for untraprecision main spindle is carried out based on the direct numerical method with assumption of point source. As a result of theoretical analysis, it is verified that coupled stiffness and damping exist and new design parameters for optimal condition of conical gas bearing are presented in dimensionless form.
