NRRO Analysis of HDD Ball Bearings with Geometric Imperfections
기하학적 형상오차를 갖는 정보저장기기용 볼베어링의 NRRO 해석
Abstract
In this paper, we theoretically analyzed the NRRO(the non-repeatable run-out) of a ball bearing with geometric imperfection. The quasi-static and dynamic analysis of a ball bearing was performed to calculate the displacement of shaft center caused by the form errors while the shaft is rotating. From consideration of the generating mechanism of NRRO, it is found that the waviness of one ball generates vibrations with nf
