How To Compute The Number Of Teeth Required In A Train Of Wheels To Produce A Given Velocity
Rule
Multiply the number of teeth in the driver by its number of revolutions, and divide the product by the number of revolutions of each pinion, for each driver and pinion.
Example
If a driver in a train of three wheels has 90 teeth, and makes 2 revolutions, and the velocities required are 2, 10, and 18, what are the number of teeth in each of the other two?
10 : 90 :: 2 : 18 = teeth in 2d wheel. 18: 90 :: 2 : 10 = teeth in 3d wheel.
How To Compute The Circumference Of A Wheel. Rule
