Abstract: A rolling element bearing includes a plurality of rolling elements that are arranged circumferentially around an axis, and radially between a bearing inner ring and a bearing outer ring. The inner ring extends axially between a first end and a second end, and includes a plurality of passages that are fluidly coupled with a channel. The passages are arranged circumferentially around the axis. The channel extends axially into the inner ring from the second end, and includes a gutter that extends radially into and axially within the inner ring.

Abstract: A rolling element bearing includes a plurality of rolling elements, a bearing inner ring and a bearing outer ring. The rolling elements are arranged circumferentially around an axis, and radially between the inner ring and the outer ring. The inner ring includes a plurality of first passages, a second passage and a channel that extends axially into the inner ring. The first passages are arranged circumferentially around the axis. The first passages respectively extend axially through the inner ring from a plurality of first passage inlets to the channel. The second passage includes a second passage inlet that is substantially axially aligned with one of the first passage inlets. The second passage extends radially through the inner ring to a second passage outlet.
Abstract translation: 滚动体轴承包括多个滚动元件，一个轴承内圈和一个轴承外圈。 滚动元件围绕轴线周向地布置，并且在内环和外环之间径向地布置。 内环包括多个第一通道，第二通道和沿轴向延伸到内环的通道。 第一通道围绕轴线周向布置。 第一通道分别从多个第一通道入口轴向延伸穿过内环到通道。 第二通道包括与第一通道入口中的一个基本上轴向对准的第二通道入口。 第二通道径向延伸通过内环到第二通道出口。
