Vibration Analysis of Ball Bearings with Ball Geometric Imperfections
볼의 기하학적 불완전성을 갖는 볼베어링의 진동해
Abstract
In this paper, we theoretically analyzed the NRRO(the non-repeatable run-out) of a ball bearing with ball geometric imperfection. The quasi-static and dynamic analysis of a ball bearing was performed to calculate the displacement of shaft center caused by the ball form errors while the shaft is rotating. From consideration of the generating mechanism of NRRO, it is found that the size and form errors of ball generate vibrations with (equation omitted)
