Calculate sprocket teeth,
chain length, and
rpm output speed.
Sprocket
Calculator
Entry Form
Using This Sprocket
RPM Calculator.
Enter the drive speed in RPMs.
Enter the drive sprocket teeth
Enter the driven sprocket teeth
Adjust the number of
sprocket teeth on both
sprockets, into the calculator,
to get the calculated
output speed.
Enter drive sprocket diameter
in inches, tip of tooth to
tip of tooth.
Enter driven sprocket
diameter in Inches,
tip of tooth to tip of tooth.
Enter distance between
sprockets in inches,
center of axle shaft to shaft.
More than one stages of
sprockets speeds can be
calculated (compound drive
systems).
The output of the first stage,
becomes the input for the
next stage.
Note: idler sprockets, have
no bearing on speed changes,
they only provide tension
to the chain.
