Question

Two standard gears have 18 and 32 teeth, respectively. The diametral pitch is 10, and the pinion rotates at 1000 rpm. Determine the following:

(a) center distance,

(b) pitch diameters,

(c) circular pitch,

(d) pitch line velocity,

(e) angular velocity of the gear.

Answer 1

NOTE: The unit of the diametrical pitch is not given. The unit is usually either teeth/mm or teeth/in . For the solution, we are assuming the unit of diametrical pitch to be teeth/unit. Just replace the unit with either mm or in , depending upon whichever standard you follow.
