The one invalidation was caused by oil leakage which lead to surface bonding between the balance gear rim and the small herringbone gear,and the other one was more serious that the track trough in the balance gear surface had been abraded badly and some bate pits occured in the surface and there was a 5 mm fatigue layer.

Secondly,the mathematic programming model for tooth contact of double helical gears was built with non-linear programming method,which was based on finite element flexibility matrix,and the particular restriction conditions of double helical gears were imported.
通过改变刀具切削刃的形状,以三段抛物线代替齿条的直线齿廓,推导出了刀具齿面方程;基于有限元柔度矩阵的非线性规划法,引入人字齿轮特有的约束条件,建立人字齿轮接触问题的数学规划模型,通过一种改进的正规形求解,从而获得人字齿轮的承载传动误差;利用光栅测量系统对修形前后试验齿轮副的传动误差进行了测量并与理论计算结果进行了对比验证。
补充资料：小人种
小区域内由于人口稠密、习俗不同所形成的单独遗传的人群。这一概念由S.M.加恩于1961年提出。小人种是最低一级人种分类单位，它不是地理隔离的产物，而是由于社会习俗的不同和人口的稠密，本地出生的人不需远离本土婚配，造成长期的内部婚配，历经几个世纪的遗传所形成的人群。小人种的分化在小城镇间比在大城市之间更为明显，因为大城市的居民流动性较大。
