Two straight-toothed bevel gears mesh with a shaft angle of 90° and a diametral pitch of 5. The pinion has 20 teeth, and the gear ratio is 2:1. The addendum and dedendum are the same as for 20 stub teeth. For the gear, determine the pitch radius, cone angle, outside diameter, cone distance, and face width.
A 28-tooth spur pinion mates with a 42-tooth gear. The diametral pitch is 4 teeth/in and the
pressure angle is 20.. Make a drawing of the gears showing one tooth on each gear. Find and
tabulate the following results: the addendum, dedendum, clearance, circular pitch, tooth
thickness, and base-circle diameters; the lengths of the arc of approach, recess, and action; and
the base pitch and contact ratio.
A 21-tooth spur pinion mates with a 28-tooth gear. The diametral pitch is 3 teeth/in and the
