In this paper ,to overcome the shortcomings in 3MK133 Groove Grinder's hybrid spindle system that the shallow slots of the throttler are easy to be blocked and difficult to be disassembled to clean,we use the throttler which is put on the big-side surface of the conical bearing to replace the traditional throttler, change gap throttling to capillary throttling, and adjust the taper of the conical bearing , oil return way , seals and sealed mode.

针对 3MK133沟道磨床动静压主轴系统中，节流器浅沟容易堵塞及拆卸清洗不便等缺陷，提出采用端置式节流器替代原有的内置式浅沟节流器，变间隙节流为毛细管节流，并相应调整了主轴系统中圆锥轴承的锥度、回油通路、密封装置及密封方式。
