ABSTRACT:
A method of manufacturing a hub member (50) for use in a coaster brake (52). A supply of tubular stock material (8) is transported to a work station and the interior thereof machined to establish first and second diameters (16) and (17), respectively, separated by a shoulder (15). A cylindrical member (10) is cut from the stock (8) and placed in a fixture (36). A disc or ring member (30) has a peripheral surface with a serrated section (32) separated from a shoulder (33) by a groove (35). The disc or ring member (30) is placed on a second fixture (38) and brought into alignment with diameter (16) of the cylindrical member (10). A ring of brazing material (37) is placed in groove (35). A force is applied to move disc member (30) into the diameter (16) of the cylindrical member (10). The serrated surface (32) on disc or ring member (30 ) engages diameter (17) to distort material therein and establish a mechanical joint (44). The force continues to move the second fixture (38) toward the first fixture (36) until face (42) on shoulder (33) of the disc or ring member (30) engages shoulder (15) on cylindrical member (10). Thereafter, the cylindrical member (10) with disc or ring member (30) insert is transported to an oven and heated sufficiently to flow the brazing material (37) into joint (44) to establish a brazed joint for the hub member (50).
