According to the limiting design method of bearings, thinning a roller bearing collar and increasing its roller diameter can greatly enlarge the strength space, as well as enhance the bearings capacity and prolong its service life 滚动轴承极限设计方法指出,减薄套圈厚度,增大滚动体的直径,可有效的增大强度空间,提高承载能力,延长寿命。
The particular signals of different type of bearings are also decided for the experimental research . 3 ) at last, the evaluating method of bearings ’ remain service life is put forward towards converter trunnion bearing and the slewing bearing of rotary column . the result accords with fact basically 3)在以上研究基础上,提出了对转炉耳轴径向轴承和钢包旋转塔回转支承这两类低速重载滚动轴承的剩余寿命评估基本方法,结果较符合实际。
