ABSTRACT:
A method for making a wheel and a wheel so made is disclosed in which the tire bead seats in the rim are deformed inwardly, the wheel is held by the deformed bead seats, and the bolting surfaces of the web are machined in fixed relation to the bead seats. Preferably, the bead seats are deformed sequentially to work welded metal attachment of a web to the rim, and then place it under compression. Preferably, the bolting surface is machined in the form of a flat cone that is approximately three degrees from planar, and the lug holes are chamfered to place surrounding metal in direct compression, and to deform the conically shaped bolting surfaces into flat engagement with planar surfaces on the hubs on which the wheels are to be installed. A method of determined angularity of the web to the rim is utilized to reject poorly aligned webs before machining the bolting surfaces, and thereby prevent undo thinning of the web, and as a means of product control. Theory of the stresses in the wheel both during manufacturing and use is disclosed.
