dedendum of the tooth的意思|示意

The measuring instrument can measure addendum circle and dedendum circle diameter of odd-tooth gears.

这种测量工具用以测量奇数齿齿轮的齿顶圆和齿根圆直径。

The tooth shape deviation in the worn traction gear will increase the vibration of traction gear and traction motor, increase the noise and increase by large scale the dedendum stress.

牵引齿轮磨损产生的齿形偏差使得牵引构轮和牵引电机振动加剧，噪声增大，齿根应力大幅度增大。

Because of the tooth thickness of the dedendum is larger than that of the common involute gear and the Pitchs do not contact each other, the beam strength and surface strength of tooth are increased.

由于该齿轮的齿根厚度比普通渐开线齿轮的齿根厚，并且节点附近不相接触，因此，其轮齿弯曲强度和接触强度都提高。

Especially the accurate modeling of the transition curve of dedendum, which ensures the accuracy of bending fatigue strength of the tooth root by the finite element analysis.

特别是对齿根过渡曲线白勺准确建模，保证了对齿根弯曲疲劳强度停止有限元分析白勺准确性。
