Suppose that the pitch curve arc lengths of the driving and driven noncircular gears are S1 and S2, respectively
The derivation of the formula shows that:
By substituting the known quantity into the formula, the integral function F1 is obtained（ φ 1) And F2（ φ 2) , and then draw φ 1- f1( φ 1) And φ 2-f2( φ 2) The relationship curve is shown in Figure 1-2.
The relationship curve in Figure 1-2 is numerically integrated by trapezoidal method to obtain the relationship curve as shown in Figure 3-4, and S1 = S2 = 500.299 mm is calculated. Due to the need of subsequent interpolation calculation, the y-axis coordinate range of figure 3-4 is expanded to [0,4] π] Rad, the corresponding X-axis coordinates also increase to twice the arc length of the pitch curve.
