MANUFACTURE OF CARRIER FOR CONICAL ROLLER BEARING* AND CARRIER |
摘要 |
A cage for a frusto-conical roller bearing is formed of a punched flat material strip so that an elongated bar extends along one side of the punched strip with a number of bars extending transversely outwardly from the elongated bar with the ends of these bars being free. As a result of the punching step a number of windows are formed closed on three sides but open on the fourth side opposite the elongated bar. The transversely extending bars are bent out of the plane of the elongated bar. When the punched strip is free into a ring the free ends of the transversely extending bars are located on a circle having a different diameter than the diameter into which the elongated bar is rolled. Another bar is rolled into a ring and is connected to the free ends of the transversely extending bars. |
