Tooth root stress

The most dangerous point is at the root of the first engaged tooth of a joint. Generally, the biggest values of stress and strain may exceed the yield limit.

最危险点在接头的第一啮合齿的齿根处，最大应力应变值一般均超过屈服极限。

And it analyzed that hob tooth height and tooth top pour round radius impacted on gear tooth root crooked stress.
