我厂在試驗齿輪珩磨的基础上再吸取了国內外經驗,开展了蝸輪珩磨的試驗工作,結果光洁度提高到▽▽▽_8,齿高方向的嚙合面达60%、齿长方向达75%,并提高了精度,現已运用到实际生产中。一、蝸輪珩杆的設計和制造蝸輪珩杆結构見图1,以45号钢制成杆芯,在齿 I plant on the basis of the test gear honing draw on the experience at home and abroad to carry out the honing worm test work results finish increased to ▽ ▽ ▽ _8, tooth height direction of the engagement surface of 60%, the tooth length up to 75% And improve the accuracy, has now been applied to the actual production. First, the design and manufacture of worm gear honing worm gear rod structure shown in Figure 1, made of 45 steel rod core, the teeth
