Permanently lubricated rolling bearing for high-speed applications

摘要

The invention relates to a permanently lubricated rolling bearing for high-speed applications with between a bearing outer ring (1) and a bearing inner ring (2) and by means of a bearing cage (4) positioned at defined distances from each other and provided with a lubricant rolling elements (3), each of which at both Side surface (5a, 5b) between the bearing outer ring (1) and the bearing inner ring (2) arranged dynamic sealing means are protected. According to the invention, on at least one of the two lateral sealing means, a lubricant reservoir (9) extending in the direction of the rolling element (3) and at least partially enclosed by a reservoir ring (8) is arranged, which forms a space between the bearing outer ring (1) and the reservoir ring (8) Having passage for centrifugally assisted lubricant delivery to the rolling elements (3).
