Abstract
A small diameter plastic eel with an overrunning clutch assembly mounted to the hub of the wheel. The wheel designed to be used with self-propelled power equipment operating at less than 1000 RPM. The overrunning clutch includes a clutch housing of generally annular cross-section having an outer periphery and an inner periphery. The housing has a radial stiffness which prevents deformation of the housing during use. The housing has recesses spaced equidistantly thereabout. Each recess has a throat opening, an outer wall, and a pair of side walls. A roller bearing is located in each of the recesses. One of the side walls has a concave surface. The other side wall has a spring for engaging the roller bearing and biasing the roller bearing toward the concave surface of the side wall.
