当轴承转速达到2×105r／min时，轴承的保持架极易遭到破坏，为避免发生这样的情况，设计了一种新型轴承组件机构，该组件利用了机械传动中转速与半径成反比的原理，在不降低主轴转速的情况下仅降低轴承转速，从而避免了因高速造成的保持架损坏。附图8篇。%When bearing speed reachs 2 × 105 r/min, the cage is much easily to be damaged.In order to avoid producing such case, one kind of new type bearing unit is designed. This unit only re-duces bearing speed without reducing spindle speed, so the cage damage causeed by high speed is avoid-ed.
