摘要
影响内花键套制造精度的主要因素是热处理工艺、加工工艺及制造工艺顺序等。研究分析表明 ,在零件加工和热处理过程中采用加空心芯轴 ,可使工艺精度比设计精度提高一级 ;淬火时用空冷代替油冷以及使工件在各阶段加热过程中尽量架空等措施 ,有利于减少内花键套应力和畸变 。
The main factors affecting the process tolerance of inner splined sleeve are heat treatment,cutting process,and the arrangement of final machining process etc.The results showed that the following process techniques adopted including applying a muff mandrel to the cutting process and heat treatment,increasing process precision one grade higher than design requirements,by air quenching replacing oil cooling and by suspending parts during all heat process and so on,can decrease the stress and the distortion of inner splined sleeve,and get the precision control.
