Enter the tangential load (lbs), the pitch (1/in), the Lewis factor, and the face width (in) into the Gear Strength Calculator. The calculator will evaluate the Gear Strength.

## Gear Strength Formula

The following formula is used to calculate the Gear Strength.

GS = TL * P / (F*Y)

Variables:

• GS is the Gear Strength (PSI)
• TL is the tangential load (lbs)
• P is the pitch (1/in)
• F is the face width (in)
• Y is the Lewis Factor

## How to Calculate Gear Strength?

The following steps outline how to calculate the Gear Strength.

1. First, determine the tangential load (lbs).
2. Next, determine the pitch (1/in).
3. Next, determine the face width (in).
4. Next, determine the Lewis Factor.
5. Next, gather the formula from above = GS = TL * P / (F*Y).
6. Finally, calculate the Gear Strength.
7. After inserting the variables and calculating the result, check your answer with the calculator above.
