The invention discloses a rolling bearing inner ring is not easy to loose the superfinishing machine bearing fixture includes a turntable, short axis and a centering shaft to be machined, the bearing inner ring is sheathed on the centering shaft, the centering shaft is stuck on the support for centring ceramic blocks to be processed bearing a pair of symmetrically arranged and fixed, radial wear in fixed on the spindle is arranged on the short axis of the hole, short shaft are respectively arranged at both ends and the end offset processing of bearing inner ring rolling bearings at both ends of the short axle are respectively provided with a center hole, the center screw is screwed with a locking screw to be processed and the other end surface of the inner ring of the bearing turntable. When the expansion screw is screwed into the central screw hole of the invention, because of the action of the conical part, the short shaft ends slightly expand outward, which plays a certain role in loosening the inner ring of the rolling bearing, and does not affect the replacement of the rolling bearing.

一种滚动轴承内圈不易松动的超精机轴承内圈夹具
本专利技术涉及超精机
,尤其是一种滚动轴承内圈不易松动的超精机轴承内圈夹具。
技术介绍
为提高圆锥滚子轴承内圈挡边内侧面的表面粗糙度,以降低轴承噪音和提高轴承的寿命,人们在超精机上通过夹具对轴承内圈挡边进行超精加工,该夹具具有套装轴承内圈的定心轴,定心轴由超精机上的定心轴驱动装置直线驱动,轴承内圈一侧与转盘相抵,轴承内圈通过转盘驱动而转动,转盘由超精机上的转盘驱动装置驱动,轴承内圈另一侧与一对起压轮作用的滚动轴承相抵,滚动轴承,两滚动轴承分别套装在压轮轴的两端,人们发现:两滚动轴承工作一段时间后,滚动轴承内圈易于松动。
