Enclosure for use in gear box that forms support of e.g. pump, of dual-body and dual-flow turbojet engine, has push button secured to cover to control holding of friction ring supported against lateral surface perpendicular to shaft's axis

摘要

The enclosure has a wall (141), and a rotary shaft (16b) e.g. rotor drive shaft, comprising a passage across the wall. A sealing device seals the passage across the wall and includes a seal with an annular friction ring (21') axially moving with respect to an axis of the shaft. The ring is maintained in sliding support against a lateral surface (22'a) perpendicular to the axis by a spring (23'). A removable cover (143') closes the passage of the shaft. A push button (143'a) is secured to the cover to control holding of the ring supported against the surface perpendicular to the axis.
