## Gear Mesh Frequency Formula

The following two example problems outline the steps and information needed to calculate the Gear Mesh Frequency.

GMF = R * N

Variables:

- GMF is the Gear Mesh Frequency (CPM)
- R is the gear rotation rate (RPM)
- N is the number of teeth on the gear

To calculate gear mesh frequency, multiply the gear rotation rate by the number of teeth on the gear.

## How to Calculate Gear Mesh Frequency?

The following steps outline how to calculate the Gear Mesh Frequency.

- First, determine the gear rotation rate (RPM).
- Next, determine the number of teeth on the gear.
- Next, gather the formula from above = GMF = R * #N.
- Finally, calculate the Gear Mesh Frequency.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

gear rotation rate (RPM) = 300

number of teeth on the gear = 20

GMF = R * #N** **= ?
