실측형상오차를 이용한 HDD 스핀들용 볼베어링의 NRRO 해석

NRRO Analysis of a HDD Spindle Ball Bearing using Measured Geometric Imperfection

  • 발행 : 2002.11.01

초록

This paper presents theoretical analysis of the NRRO(the non-repeatable run-out) for a ball bearing with geometric imperfection. The 3DOF dynamic analysis of a ball bearing using the Runge-Kutta method is performed to calculate the displacement of shaft center. Frequency and magnitude characteristics of radial and axial vibrations are investigated. The ball form errors of the ball, the inner race, and the outer race in a HDD spindle ball bearing are precisely measured. (omitted)
