Find the maximum value of addendum radius of the larger gear if the pinion has 17 teeth, the larger gear has 51 teeth and the pressure angle is equal to 15°. Take the value of module as 8 mm.

Find the maximum value of addendum radius of the larger gear if the pinion has 17 teeth, the larger gear has 51 teeth and the pressure angle is equal to 15°. Take the value of module as 8 mm. Correct Answer 5.247 mm

: φ = 15°, t = 17 and T = 51, G = T/t = 51/17 = 3, m = 8 mm R = mT/2 = 204 mm aw max = R((1+(1/G)((1/G)+2)sin2φ)0.5 – 1) = 5.247 mm.
