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.
