A pair of helical gears, on parallel axes, are to have involute teeth, of 20° normal pressure angle, and 3 mm normal module. The wheels are to have 24 and 33 teeth, and to work with a centre distance of 143 mm. Calculate the pitch helix angle in degrees. Give your answer to 2dp.
A similar pair of helical gears to that in Q1, also on parallel axes, are to have involute teeth, of 20° normal pressure angle, and 3 mm normal module. The wheels are to have 23 and 37 teeth, and to work with a centre distance of 143 mm. Calculate the transverse pressure angle in degrees. Give your answer to 2dp.
