ABSTRACT:
The races of tapered roller bearing, that is the cone and cup of such a bearing, are composite in construction, each including a sheet metal shell form and a core that is cast within the shell form for rigidifying it. Each shell form has spaced apart walls, one of which is tapered and forms a raceway and the other of which is cylindrical. In addition each shell form has an end wall at which the two spaced apart walls are joined. The walls define a cavity that opens out of the shell form at the end opposite from the end wall. The core is within the cavity where it is bonded to the sheet metal walls. While the metal of the shell form may be high alloy vacuum melt steel, the metal of the core may be less expensive. In the production of the races, the shell form serves as a mold for holding the molten core metal as that metal cools and solidifies.
