1. Preliminary design calculations have suggested that design objectives may be met by a straight spur gearset using standard full-depth 2 -pitch involute gear teeth, and a 21-tooth pinion meshing with a 28-tooth gear. A 25 pressure angle has been selected for this application, and the gear teeth are to be shaved to AGMA quality number . Find the following:
a. Addendum.
b. Dedendum.
c. Clearance.
d. Circular pitch.
e. Circular tooth thickness.
f. Base pitch .
g. Length of action.
h. Profile contact ratio.
i. Module 15-27. Repeat problem 15-26, except for a 20 pressure angle.
