TRUNNION FOR HIGH-PRESSURE TURBINE, AND TURBOJET ENGINE INCLUDING SUCH A TRUNNION
Abstract:
The invention relates to a trunnion (23) for a high-pressure turbine (11), to be arranged between a shaft of a low-pressure turbine (9) and an inner surface (34) of a seal mounting (26) of the low-pressure turbine (8), the trunnion (23) being characterised in that it includes a drop-launching extension (32) arranged such as to extend opposite a flared portion (33) of the inner surface (34) of the seal mounting (26), such that when the trunnion (23) is rotated about the shaft of the low-pressure turbine (9), oil (H2), which tends to penetrate between the trunnion (23) and the seal mounting (26), is thrown by centrifugal effect from the drop-launching extension (32) toward the flared portion (33) of the inner surface (34) of the seal mounting (26).
Abstract(Chinese):

本发明涉及一种用于高压涡轮机（11）的耳轴（23），其布置在低压涡轮机（9）的轴与密封件安装件（26）的内表面（34）之间 低压涡轮机（8），耳轴（23）的特征在于它包括一个下落发射延伸部（32），其布置成与密封件安装件的内表面（34）的扩口部分（33）相对延伸 （26），使得当所述耳轴（23）围绕所述低压涡轮机（9）的轴旋转时，容易穿过所述耳轴（23）和所述密封件安装件（26）之间的油（H2） 通过离心效应从下落推进件（32）向密封件安装件（26）的内表面（34）的扩口部分（33）抛出。
