centrifugal effect 離心作用。

centrifugal force

As to the high speed of electric spindle system , the angle - contact bearings are usually applied to supporting the shafts . because the supporting stiffness of rolling bearing is non - linear , especially under the circumstances of high speed and ultrahigh speed , the internal working status is so complicated that it is not regarded as routine linear support and ordinary non - linear support . centrifugal effect of the rolling bearing increase the factors of influencing the supporting stiffness 高速電主軸系統的轉速很高,通常都采用角接觸球軸承作為支承,由于滾動軸承的支承剛度呈非線性形式,特別在高速和超高速情況下,滾動軸承內部的動力學狀態十分復雜,由于滾動體運動所產生的離心力作用,使得影響其支承剛度的因素增多,不能作為常規的線性支承和普通的非線性支承處理。
