Abstract: A journal configured to be driven in rotation in a housing of a turbine engine, or for an aircraft, the journal including: a circumferential main body including plural ventilation openings configured to allow plural axial airflows to circulate from upstream to downstream in the turbine engine, two consecutive ventilation openings being connected by a connecting segment, and a circumferential ring for recovering a flow of lubrication oil, which ring is rigidly connected to the main body and is radially inside the ventilation openings, the recovery ring including plural radial discharge openings for allowing plural radial flows of oil to be discharged towards the outside, each discharge opening being radially aligned with a connecting segment of the main body to allow each flow of oil to be discharged between the airflows.

Abstract translation: 一种被配置为在涡轮发动机或飞行器的壳体中旋转驱动的轴颈，所述轴颈包括：周向主体，其包括多个通风开口，所述多个通风开口被构造成允许多个轴向气流从涡轮发动机的上游流向下游， 两个连续的通风口通过连接段连接，以及用于回收润滑油流的周向环，该环与主体刚性地连接并且在通风开口内部径向地设置，回收环包括多个径向排放口，用于允许 要向外部排出的多个径向流动的流体，每个排放口与主体的连接段径向对准，以允许每个气流在气流之间排放。
