stop bushing

The early failure of the stopping pad and locking nut of train electironic machine axle is analysized in the present work.

由此得到:構件失效的主要原因是:鎖緊螺母的熱處理工藝不當,止動墊電鍍過程發生氫脆。

Acoording to the technological process, the grinding allowance and the snapring groove clearance of finished bearing ring, the snap ring groove size of bearing ring on lathing was calculated with the method of technological dimension chains, in order to pledge a finished snapring groove size of bearing ring after grinding the ring, and meet users’requirement.

根據加工過程、磨加工余量大小及成品軸承套圈止動槽公差要求,應用工藝尺寸鏈方法,推算出車加工軸承套圈止動槽位置尺寸,從而保證磨加工后成品所要求的套圈止動槽位置尺寸,滿足用戶要求。

The snap spring of Rate Governor occured brittle fracture or insufficient elasticity, dimension change, uncleanliness of surface during the trial manufacture.

RQV調速器的重要零件止動彈簧在試制期間 ,常常出現脆性斷裂或彈性不足 ,尺寸變化 ,表面不清潔等質量問題 ,經過多次熱處理工藝試驗和工藝改進 ,對設備和工藝參數調整和優化后 ,很好地解決了這些質量問
