Train Value of Compound Gear Train given product of Teeth on Driven and Driver Gear Calculator

Calculate Train Value





Formula

The formula to calculate the Train Value is:

\[ T_v = \frac{P_{\text{driver}}}{P_{\text{driven}}} \]

Where:

Definition

Train value is the ratio of the speed of the driven or follower to the speed of the driver.

Example Calculation

Let's assume the following values:

Using the formula:

\[ T_v = \frac{27}{16} \]

Evaluating:

\[ T_v = 1.6875 \]

The Train Value is 1.6875.
