Force Analysis in Bevel Gears:

A bevel gear drive is utilized for intersecting shafts. The gears of a simple bevel gear drive are indicated in diagram 6. The two of the gears of simple bevel gears are illustrated separated from each other. The included cone angle for gear 2 is 2γ₂ and for the gear is 2γ₃. The normal tooth load has been indicated. This force can be supposed to act at the mean pitch radius of the pinion. The tangential component will have the line of action perpendicular to the plane of the paper and it may be estimated along the help of the angular speed, power and pitch circle radius of the driver.

here φ is the pressure angle.

That means

here γ₂ is the semi-cone angle.

For gear 3

All these three components namely  and have been illustrated acting in Figure 7.
