Find the maximum value of addendum radius of the pinion if the pinion has 25 teeth, the larger gear has 100 teeth and the pressure angle is equal to 20°. Take the value of module as 6 mm.

Find the maximum value of addendum radius of the pinion if the pinion has 25 teeth, the larger gear has 100 teeth and the pressure angle is equal to 20°. Take the value of module as 6 mm. Correct Answer 71.345 mm

Giveφ = 20°, t = 25 and T = 100, G = T/t = 100/25 = 4, m = 6 mm r = mt/2 = 75 mm a p max = r((1+G(G+2)sin2 φ)0.5-1) = 71.345 mm.
