Double comb cage for a double-row cylindrical roller bearing with mass balance

摘要

The invention relates to a double-comb cage for a double-row cylindrical roller bearing, with a central ring part (1) from which webs (2, 3) protrude axially on both sides, the webs (2, 3) of one side together with the rolling elements arranged there each having a bearing row (2). 4, 5), wherein each two adjacent webs (2, 3) of a bearing row (4, 5) delimit a receiving pocket (6, 7) for a rolling body, and in which at least one bearing row (5) the webs (3) are formed narrowed in the circumferential direction for a radial filling of the receiving pockets (7) with the rolling elements. So that the double comb cage has a perfect running behavior and is relatively simple and cost-effective to manufacture, recesses (12, 12 ', 13, 14, 16) are at the other of the two rows of bearings (4, 5) for producing a symmetrical mass distribution between the two Warehouse rows (4; 5) formed.
