Hi
A bit hypothetical but, assuming two identical gears, the driver has
100mm pitch circle and the driven has a 100mm pitch circle, they are
spaced at 100mm centres. The driven is attached to a rubber wheel.
Correctly meshed, for one revolution of one gear the other will turn one
revolution, which is a distance of 100mm x pi = 314.15mm
If the gears centres are then altered to 102mm without altering the
pitch of either (or anything else) will the driven gear travel further
or less per revolution? Is there a formula to work it out?
