Problems solved by technology

However, these bearing cages are disadvantageous because they have a non-uniform circular outer contour when assembled, which leads to an unbalance of the bearing cage during operation
In addition, non-uniformly distributed forces thus act on the bearing cage, which can lead to failure of the bearing cage and thus a complete failure of the bearing

Embodiment Construction

[0024] figure 1 and figure 2 A schematic perspective view of a split bearing cage 1 of a rolling element bearing assembly (not shown) comprising first and second bearing cage segments 2, 4, respectively, is shown. here in figure 2 , an alternative design of the proposed release bearing cage 1 is shown. Furthermore, each bearing cage segment 2, 4 comprises two side ring portions 6, 8, 10, 12, each axially spaced from each other via bridges 14, 16, between which rolling element receiving recesses are formed 18, 20. The rolling element receiving pockets 18, 20 are configured to receive rolling elements (not shown) of the rolling element bearing assembly to keep them spaced from each other and to guide them.

[0025] In order to improve the operating behavior of the split bearing cage 1 , especially for use with a one-piece crankshaft, the two bearing cage segments 2 , 4 are connected to each other via a rotary joint arrangement 22 .

[0026] like figure 1 and 2 As shown,...

Abstract

A split bearing cage for a rolling-element bearing assembly includes a first bearing cage segment and a second bearing cage segment each having two side ring sections axially spaced apart by a plurality of bridges. Adjacent pairs of the bridges define rolling-element receiving pockets for receiving rolling elements of the rolling-element bearing assembly and for holding the rolling elements spacedapart from each other and for guiding the rolling elements. The first bearing cage segment is connected to the second bearing cage segment via a swivel joint that may be formed of a bolt element on afirst end of the first bearing cage segment and an at least partial eyelet on the first end of the second bearing cage segment.

Description

technical field [0001] The present invention relates to a separation bearing cage. Background technique [0002] Bearing cages for rolling element bearings generally comprise two side rings that are axially spaced from each other by a bridge. The bridges here are arranged continuously in the circumferential direction of the bearing cage and form recesses for receiving the rolling elements. Such a bearing cage retains the rolling elements at intervals due to their arrangement in the recesses in order to enable better rolling behavior. [0003] In operation, the bearing cages are greatly mechanically stressed by frictional, shearing and tensile forces, so they are usually constructed in one piece and are made, for example, from sheet steel. [0004] However, if axial mounting of the bearing cage to the bearing location is not possible, such as with a one-piece crankshaft, which is typically constructed with angled roller supports, the use of a one-piece bearing cage is not p...
