crowned flat belt pulley

why is the flat belt pulley crowned or tapered at slight angle toward the two sides of the pulley.is there a design calculation for the tapered angle for different diameter and width of the flat belt pulley

A pulley is crowned to ensure that the belt remains centered on the pulley.

The total height of the crown is a function of the elasticity of the belt, the diameter of the pulley and the speed of the belt. There are calculations and rules of thumb for determining the correct crown height.

Look on the internet with the phrase – determining the height of a pulley crown- using your favorite search engine. There are a number of useful pages with the information presented in a number of ways.
