1.A proposed worm gearset is to have a single-start worm with a pitch diameter of 1.250 inches, a diametral pitch of 10, and a normal pressure angle of 14 . The worm is to mesh with a worm gear having 40 teeth and a face width of 0.625 inch. Calculate the following:
a. Axial pitch b. Lead of the word.
c. Circular pitch .
d. Lead angle of the worm.
e. Helix angle of the worm gear 1 2°.
f. Addendum g. Dedendum .
h. Outside diameter of the worm.
i. Root diameter of the worm,
j. Pitch diameter of the gear .
k. Center distance.
l. Velocity ratio.
m. Root diameter of the gear.
n. Approximate outside diameter of the gear.
