Abstract
A pulley and bearing assembly and a method of inserting and fastening a bearing within a pulley having an axially extending cylindrical hub portion with an axial bore forming an inner periphery of the pulley and a pair of opposite ends, an annular belt groove portion around an outer periphery of the pulley and annular disk shaped body portion extending radially between the hub and belt groove portion, the steps comprising: clamping the pulley in a fixed axial position, providing a bearing of a slightly larger outside diameter than the inside diameter of the bore of the hub, axially aligning the bearing with the bore of the hub, applying axial pressure to one side of the bearing to move it into the bore in a force fit therewith, and applying axial pressure simultaneously to both ends of the hub to crimp the ends of the hub around the bearing near its circumference to retain the bearing within the hub. An apparatus for performing the above described method is a vertical press having an annular crimping tooling assembly carried by the press and having upper and lower parts which are moved axially by the press to grip the pulley and insert the bearing in the hub of the pulley and crimp the hub around the bearing. An alternative to crimping the hub around the bearing, is the application of a layer of adhesive to one or both of the contacting surfaces of the bearing and the bore of the hub before inserting the bearing into the hub.
