n.齿轮的齿根高(齿高)

Clearance: the different between the dedendum and the addendum. 间隙---齿顶高与齿根高之间的偏差。

Strength design from considering the tooth surface pressure lubrication condition and dedendum intensity of two aspects. 强度设计是从考虑润滑条件的齿面压力和齿根强度两个方面进行的。

Need to manually file repair parts to keep it Dedendum R0.5, low efficiency, accuracy requirements can not be guaranteed. 需手工修锉齿根部位使其保持R0.

The purpose was to gain new knowledge about the magnitude and distribution of the actual stresses occurring in the dedendum. 并把测量结果与理论计算进行了比较,提供了关于圆弧齿轮齿根上实际存在的应力大小和分布的新知识。

In order to avoid the “midconvex” of tooth profile and the serious abrasion in dedendum, the technology of center distance variation was adopted. 为了避免出现齿面“中凸”及齿根部研磨较严重的现象，采用了变中心距研齿工艺。
