Abstract

1,197,911. Removable cores; moulding bearing cages. F. LEGROM. 12 July, 1967 [13 July, 1966], No. 32157/67. Heading B5A. [Also in Divisions B3 and F2] In the die-casting or injection-moulding of a cage for a roller bearing, pockets for holding the rolling elements are formed with projecting retaining lips 8, 9, 12, 13 by the use of a collapsible core having three slider parts 4, 5 and 6. Outer parts 4 and 5 have beads 18, 19, chamfers 10, 11 and notches 14, 15 that form the shape and lips of the pockets, and centre part 6 is radially slidable to release the outer parts 4 and 5. The centre part 6 has tapered sides and the outer parts 4 and 5 may be spring urged towards each other. A centre core 1 and outer core 2 form the inner and outer surfaces of the cage. The cage material may be synthetic resin.
