Question
A spur pinion of pitch diameter mm rotates at rad/s and transmits kW power. The pressure angle of the tooth of the pinion is . Assuming that only one pair of the teeth is in contact, the total force (in newton) exerted by a tooth of the pinion on the tooth on a mating gear is _______
Correct answer
638 to 639
Solution
1.Calculate the torque ():
Power .2.Calculate the tangential force ():
The pitch radius ..
3.Calculate the total force ():
The total force exerted is the resultant force along the line of action, which is related to the tangential force by the pressure angle ..
