For a two start worm gear having a pitch of 20 mm and a lead angle 12°, find the centre distance if the larger gear has 25 teeth.

For a two start worm gear having a pitch of 20 mm and a lead angle 12°, find the centre distance if the larger gear has 25 teeth. Correct Answer 109.53 mm

C = (mn/2)(T1 cotλ1 + T2) Therefore, C = (pn/2π)(T1 cotλ1 + T2) = 109.53 mm.
