## Calculate the pitch diameter of the worm gear.

1.A double-start worm has a lead of 60 mm. The meshing worm gear has 30 teeth, and has been cut using a hob having a module of 8.5 in the normal plane. Do the following:

a. Calculate the pitch diameter of the worm.

b. Calculate the pitch diameter of the worm gear.

c. Calculate the center distance and determine whether it lies in the range of usual practice.

d. Calculate the reduction ratio of the worm gearset.

e. Calculate the diametral pitch of the gearset.

f. Calculate the outside diameter of the worm (mm).

g. Calculate the approximate outside diameter of the worm gear (mm).
