<p>#CMT# #/CMT# The disk (1) has a recessed central zone (10), a circular base (20), a transition zone (30) and a peripheral flange ring (40) from a center of the disk towards a periphery of the disk. The transition zone has a minimum thickness (e1) at an edge (41) of the flange ring. The minimum thickness is determined with the help of thickness relation constituting parameters such as constant depending on an alignment defect, torque applied on a transmission torque, distance (r), and radius (R) of the central zone, to thickness of the zone (30) at the distance from a rotational axis (AX). #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a flexible disk. #CMT#USE : #/CMT# Flexible disk for forming flexible coupling of a mounting clip in a transmission shaft (all claimed) for linking the transmission shaft in a rotation manner to a mechanical part e.g. free turbine turboshaft engine, of a rotorcraft, despite of an alignment defect, to transmit power from the mechanical part connected to a main transmission gearbox of the rotorcraft via the shaft. #CMT#ADVANTAGE : #/CMT# The minimum thickness is determined with the help of the thickness relation constituting parameters to the thickness of the transition zone at the distance from the rotational axis, thus permitting calculated thickness to resist to different solicitations during utilization of the disk, and preventing modification displacement of the flange ring, and hence presenting the disk with an unlimited length of life, avoiding breakage of the disk at border separating the transition zone from the peripheral flange ring. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a flexible disk.
