ABSTRACT:
A centrifugally operated variable speed drive pulley comprises a hub aligned with a rotation axis. Two annular flanges around the hub in face-to-face relationship receive a transmission belt. At least one of these flanges is able to slide along the hub. A transverse bearing member is mounted on the hub and a diaphragm spring is disposed between the mobile flange and the transverse bearing member. The diaphragm spring is able to flex in such a way as to control sliding movement of the mobile flange along the hub. A plurality of flyweights are carried by the diaphragm spring. The flyweights are at least partially embedded in a mass of molded material applied to the diaphragm spring.
