Method for the reconditioning and use of brake discs of the rear stator type with studs, assembled disc and corresponding stack of discs

摘要

A method for the reconditioning and use of brake discs of the rear stator type with studs. The method includes the steps of using a first disc (12) during a first life, using a second disc (112) during a first life, after the first life of the first disc and the first life of the second disc, machining a friction surface on one of the discs and a rear surface on the other of the discs so that one of the surfaces has at least one shoulder (17) and the other of the surfaces has at least one notch (118). Finally, the first disc is nested in the second disc such that the notch and the shoulder cooperate so as to center the discs.

1. Method for the reconditioning and use of aircraft brake discs of the rear stator type with studs, the method comprising the steps of:
using a first disc (12) during a first life as the rear stator disc with studs from a first stack of brake discs, the first disc having an initial thickness at the start of the first life, using a second disc (112) during a first life as the rear stator disc with studs from a second stack of brake discs, the second disc at the start of the first life being substantially identical to the first disc at the start of the first life, after the first life of the first disc and the first life of the second disc, machining a friction surface (13) on one of the discs and a rear surface (114) on the other of the discs so that one of said surfaces comprises at least one shoulder (17) and the other of said surfaces comprises at least one notch (118) capable of cooperating with said shoulder, nesting the first disc in the second disc such that the notch and the shoulder cooperate so as to centre the discs, fixing the two discs to one another to form an assembled disc (212), the assembled disc having a thickness which is substantially identical to the initial thickness, fixing studs to the assembled disc, using the assembled disc during an additional life as the rear stator disc with studs from a third stack of brake discs.
