![]() Power transmitting component is tangential force (F T).Īlways see carefully which force component is asked to calculate out of 3 components and calculate accordingly. If this gear possessed 20 teeth then its pitch radius could be quoted as 40 mm ( 1) or as 10 (no units). Hence, magnitude of radial force (F R) = 0.72794 kN ≈ 0.73 kN dedendum : b 1.25 fillet radius : e 0.38. \(P = Tω \Rightarrow T = \frac \times 1000 = 2000N\)į R = (2000) tan (20°) = 727.94 N = 0.72794 kN The effect on gear strength with variation of root fillet design using FEA is dealt with and the loading is done at the highest point of single tooth contact (HPSTC). Given data Power (P) = 20 kW = 20 × 10 3 W First is tangential component which helps in transmitting power. 15) Fillet Radius: The small radius that connects the profile of a tooth to the root circle. This force along the pressure line can be resolved into two components. This line is also the common normal at the point of contact of the two mating gears and is known as the line of action or pressure line. The force which driving tooth exerts on the driven tooth is along a line from the pitch point to point of contact of the two teeth.
