Angle of Contact for Cross Belt Drive Calculator

Formula

The formula to calculate the Angle of Contact for a Cross Belt Drive is:

$\theta_{contact} = \frac{180 \cdot \pi}{180} + 2 \cdot \alpha$

Where:

The Angle of Contact is the angle subtended by the belt on the pulley.

Let's assume the following value:

Using the formula:

$\theta_{contact} = \frac{180 \cdot \pi}{180} + 2 \cdot 0.523$

Evaluating:

$\theta_{contact} = 4.18759265358979 \text{ rad}$

The Angle of Contact for the Cross Belt Drive is 4.18759265358979 rad.
