Abstract

The invention relates to a rolling bearing cage (10) or a section for a rolling bearing cage, which is designed to hold at least one rolling body (12) of a rolling bearing (14) in a rolling body region (16). In addition, the rolling bearing cage (10) or section has a lubricating material storage area (18), which is designed to accommodate a pasty lubricating material (20), so that when the rolling bearing (14) rotates, the lubricating material and the rolling bearing cage The rolling body regions ( 16 ) of ( 10 ) and / or the running surfaces ( 22 ) of the rolling bodies ( 12 ) are held at intervals in the lubricant reservoir region ( 18 ). The lubricating material storage area (16) has at least one opening through which lubricating fluid (26) discharged from the lubricating material (20) under the effect of force and / or temperature changes can flow out towards the rolling element area (16).

Description

technical field

[0001] Embodiments relate to a rolling bearing cage according to claim 1 or to a section for a rolling bearing cage and to a rolling bearing according to claim 9 . Background technique

[0002] Rolling bearing cages or sections of rolling bearing cages are used in rolling bearings to hold or guide rolling bodies between an inner ring and an outer ring. In order to lubricate the bearing, a lubricating compound or grease is usually introduced into the inner space of the bearing or between the inner ring and the outer ring. However, this has the consequence that the lubricating material or the grease is present in areas of the bearing that do not need to be lubricated over the entire service life, but is not able to significantly participate in the lubrication of the rolling elements during the operation of the bearing. For example, unused lubricating material often accumulates in an area of ​​the bearing interior that does not need to be lubricated. In the ca...
