Stresses in a Pulley

The stresses in a pulley connected to an engine that drives another pulley are studied in this model.

A parametric analysis is conducted in order to study how the rotational speed affects the stress distribution in the pulley. The power at the pulley shaft remains constant, the moment (defined by the ratio of the power by the rotational speed) will thus decrease with increased speed. This means that with increased rotational speed the inertial load increases and at the same time the driving belt-force decreases.

Von Misses stress distribution at n=9000 rotations/min.
