## What are gear ratios?

A gear ratio is the ratio of the number of rotations of a driver gear to the number of rotations of a driven gear. A colon is often used to show a gear ratio: gear ratio = rotations of a driver gear : rotations of a driven gear.

Chordal addendum: The distance between a chord, passing through the points where. the pitch circle crosses the tooth profile and the tooth top.

## What is module in gear?

What is the module of a gear ? In general, the size of a gear tooth is expressed as its module. The sizes of gear teeth using the module system are indicated with the symbol m followed by numerals such as m1, m2, and m4 where the teeth sizes get larger as the numerical value increases.
