How To Compute The Number Of Teeth In A Pinion Or Follower To Have A Given Velocity
Rule
Multiply the velocity of the driver by its number of teeth, and divide the product by the velocity of the driven.
Example
The velocity of a driver is 16 revolutions, the number of its teeth 54, and the velocity of the pinion is 48; what is the number of its teeth?
2. A wheel having 75 teeth is making 16 revolutions per minute ; what is the number of teeth required in the pinion to make 24 revolutions in the same time?
16 X 54 / 48 = 18 teeth.
