Problems solved by technology

This particularly disadvantageously results in little or no lubricant being present on the rolling elements, especially in the region of the retaining rib, so that insufficient lubrication occurs here.
Said insufficient lubrication again leads to an undesired temperature rise of the rolling bearing elements and thus to excessive wear and a shortened service life

Embodiment Construction

[0024] The following identical or functionally identical elements are assigned the same reference numerals.

[0025] figure 1 A schematic sectional view through a rolling bearing 1 according to the invention is shown, which is designed as a tapered roller bearing. Such as figure 1 As shown, the tapered roller bearing 1 has a bearing outer ring 2 and a bearing inner ring 4 with rolling elements 6 arranged between them. In turn, retaining ribs 12 and guide ribs 10 are formed on the bearing inner ring 4 , which likewise serve for defined positioning of the rolling elements 6 . It is also shown that the rolling bodies 6 are accommodated in a bearing cage 8 , which supports the rolling bodies in the axial direction and separates the rolling bodies from one another in the circumferential direction.

[0026] Especially in lubricated tapered roller bearings, due to the conical shape of the rolling bearing, a pumping effect of the lubricant from the smaller diameter to the larger di...

Abstract

A bearing cage for a tapered rolling-element bearing includes at least one first ring element and at least one second ring element connected to the at least one first ring element via at least one bridge. The first ring element and the second ring element are configured to receive at least one rolling element between them and to retain the rolling element axially, the bridge is configured to retain the at least one rolling element circumferentially, and the at least one first ring element includes a flange extending at least partially radially outward beyond a radially outer surface of the at least one bridge.

Description

technical field [0001] The invention relates to a bearing cage for rolling bearings, in particular tapered roller bearings, which has at least one first ring part and a second ring part, which are connected to each other by at least one transverse beam, wherein the first ring part and the second ring part The parts are designed to accommodate at least one rolling body between them and hold the rolling body in the axial direction, and at least one crossbeam is designed to hold the rolling body in the circumferential direction. Background technique [0002] Rolling element bearings, in particular tapered roller bearings, generally have a bearing outer ring and a bearing inner ring, between which the rolling elements are arranged so that a relative movement takes place between the outer ring and the inner ring. Here too, the rolling bearings can be designed to be fully rolling such that the rolling bodies are in direct contact with each other, or the rolling bodies are accommod...
