Beschreibung
Zusammenfassung:	The invention relates to a turbojet bearing housing comprising a stationary envelope (13) through which a rotor (2) passes, said envelope (13) comprising a cylindrical end (32) surrounding a joint (18) that ensures the tightness of the cylindrical end (32) of the envelope with the rotor (2), said envelope (13) being provided with a casing (37) screwed onto the cylindrical end (32) thereof, said casing (37) comprising radial channels (47) that open up opposite said joint (18) and are arranged such that an air stream passing through the joint (18) towards the housing comes mainly from said radial channels (47). 本发明涉及一种涡轮喷气发动机的轴承壳体，轴承壳体包括由转子(2)穿过的固定封壳(13)，所述封壳(13)包括围绕连接部(18)的圆柱形端部(32)，该连接部确保封壳的圆柱形端部(32)与转子(2)的密封性，所述封壳(13)设置有旋拧到该封壳的圆柱形端部(32)上的壳部(37)，所述壳部(37)包括与所述连接部(18)相对地向上开口的径向通道(47)并且被布置成使得朝向壳体穿过连接部(18)的空气流主要来自所述径向通道(47)。
