is a rectangle bending flexibility, is a trapezoid bending flexibility, is a share flexibility, is a flexibility caused by tooth base rotations, and is an elastic modulus. Moreover, , , and are geometry parameters of pinions and is an acting angle. Both geometry parameters and acting angle can be calculated, according to [16].
