Abstract:
A self-cleaning pulley device for preventing improper pulley functioning in a contamination prone machine environment, the self-cleaning pulley device comprising:(a) a cylindrical member including a body portion having an outer surface and an inner cavity;(b) a series of spaced apart recesses formed from said outer surface into said body portion, each recess of said series of recesses having a root portion, and said series of recesses defining a series of spaced apart ridges projecting above root portions of said series of recesses for engaging corresponding recesses of a belt mounted on said body portion for movement over said cylindrical member; and(c) a dirt aperture formed from within each said root portion through said body portion and into said inner cavity for collecting any dirt particles and contamination entering into an area between said body portion of said 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 said pulley device.
