ABSTRACT:
A belt pulley is described which includes a pulley member and a flanged wheel. The pulley member has a belt-bearing surface and a projection disposed at a position axially adjacent to the belt-bearing surface. The flanged wheel is capable of being assembled separately on the pulley member and includes a spring washer having an inside diameter and an outside diameter. The spring washer is substantially elastically extendable in the area of the inside diameter. The dimensions of the inside diameter are defined such that, upon assembly, the inside diameter elastically extends and touches upon a surface of the projection over at least a portion of the inside diameter such that the flanged wheel is mounted concentrically and non-rotatably in relation to the belt-bearing surface. The inner and outer diameters of the spring washer are defined such that, upon assembly, the flanged wheel projects outwardly in a radial direction beyond the belt-bearing surface, thereby delimiting the belt-bearing surface in the axial direction.
