Abstract

A pulley intended to be mounted around a rolling bearing and having an inner web for connecting to an outer race of the rolling bearing, an outer web for connecting to a flexible force-transmitting element, and radial connecting ribs between the outer web and the inner web. The ribs are distributed in several groups, each group providing at least three successive ribs, which form several pairs of adjacent ribs, the midplanes of which are separated two by two at a regular angle, and the angle between the midplanes of two adjacent ribs in one and the same group varies, between two adjacent groups, by at least 5% with respect to the smaller of the two angles.
