ultrahigh-speed
解釋
特高速-
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
