An Analysis of Coupled Oil-lubricated Groove Journal and Thrust Bearings for Spindle Motor
빗살무늬 저널베어링과 스러스트 베어링으로 이루어진 오일윤활 스핀들 모터 베어링 해석
Abstract
In this paper, the dynamic characteristics of coupled herringbone groove journal bearings and spiral groove thrust bearings with conical motion were numerically analyzed, The bearing performance characteristics were calculated by the perturbation method and are solved by FDM. Stability of bearing was obtained from the threshold of instability.
