HIGH PRESSURE TURBINE TOURILLON, AND TURBOREACTOR INCLUDING SUCH A TOURILLON

摘要

The invention relates to a pin (23) for a high-pressure turbine (11) intended to be arranged between a low-pressure turbine shaft (9) and an inner surface (34) of a low-turbine gasket support (26). pressure (8), the trunnion (23) being characterized in that it comprises a droplet extension (32) arranged to extend facing a flared portion (33) of the inner surface (34) of the support seal (26), so that when the journal (23) is rotated about the low pressure turbine shaft (9), oil (H2) tending to penetrate between the journal (23) and the seal support (26) is centrifugally projected from the droplet extension (32) to the flared portion (33) of the inner surface (34) of the seal support (26).
