COUPLING AND UNCOUPLING MECHANISM FOR AN ONBOARD DEVICE OF A TURBOJET ENGINE NACELLE

摘要

A mechanism for coupling and uncoupling a motor inlet shaft and an outlet shaft, in particular, the inlet shaft is mounted in rotation on a front frame, and the outlet shaft is mounted in rotation on a rear frame. The outlet shaft rotates an outlet pinion, and the rear frame is slidably mounted to translate between a forward compact position and a backward deployed position. The mechanism includes a coupler, and first and second lockers to couple or uncouple the inlet and outlet shafts according to the translation of the rear frame between the forward compact position and the backward deployed position. The first locker locks in rotation the inlet shaft on the front frame, the second locker locks the outlet shaft on the rear frame. In particular, the second locker automatically locks the inlet and outlet shafts in rotation respectively, according to the displacement of the rear frame.

1. A mechanism for coupling and uncoupling an inlet shaft which is mounted in rotation on a front frame around a secondary longitudinal axis, and an outlet shaft which is mounted in rotation on a rear frame around the secondary axis and which drives in rotation an outlet pinion, the rear frame being slidably mounted from front to back with respect to the front frame, along a longitudinal direction, between a forward compact position and a backward deployed position, said mechanism comprising:
a coupling means configured to couple in rotation the inlet shaft and the outlet shaft together when the rear frame occupies the forward compact position, the coupling means configured to uncouple the inlet shaft and the outlet shaft when the rear frame occupies the backward deployed position; a first means for locking in rotation the inlet shaft on the front frame; and a second means for locking in rotation the outlet shaft on the rear frame, the second means configured to automatically lock the inlet shaft and the outlet shaft in rotation respectively, under the effect of a displacement of the rear frame towards the backward deployed position.
