Abstract
A self-cleaning pulley device includes a cylindrical member including a body portion having an outer surface; a series of spaced apart recesses formed from the outer surface into the body portion, each recess of the series of recesses having a root portion, and the series of recesses defining a series of spaced apart ridges projecting above root portions for engaging corresponding recesses of a belt mounted on the body portion for movement over the cylindrical member. Importantly, the self-cleaning pulley device includes a series of dirt apertures formed at least one within each root portion of each recess for collecting any dirt particles and contamination entering into an area between the body portion of the cylindrical member and a belt mounted thereon, thereby self-cleaning the pulley device, eliminating noise and preventing functional inefficiencies in a belt and pulley assembly using the pulley device.
