Question:

A pair of meshing gears. Which gear has a large bending stress?

A pair of meshing gears. Which gear has a large bending stress?

Answer:

Therefore, the allowable bending stress of the pinion is greater than that of the large gear.
The coefficient of tooth shape YF1 > YF2, because the material is different, the hardness of the pinion is greater than the hardness of the big gear
The bending stress of the pinion is large, which can be seen from the coefficient of gear shape of the two gear and the selected material
