A parallel-axis helical gearset is made with a 20 transverse pressure angle and a 35 helix angle.

Question:

A parallel-axis helical gearset is made with a 20◦

transverse pressure angle and a 35◦ helix angle. The gears have diametral pitch of 10 teeth/in and have 15 and 25 teeth, respectively. If the face width is 0.75 in, calculate the base helix angle and the axial contact ratio.
