但对高周次疲劳损伤，进行修复退火不能愈合裂纹和延长寿命。
But for the specimens of high cycle fatigue damaged, the annealing can not increase the total life.
维修方法：更换精准表离合轮和小钢轮或者把磨损齿轮经过退火处理，修复磨损齿轮再把退火的齿轮进行淬火处理。
Maintenance methods: replace the precision of the clutch wheel and the small steel wheel or wear the gear after annealing treatment, repair the wear gear and then annealing the gear quenching.
