Abstract
A multiple rotating disk assembly comprises a stack of disks including first disks constrained to rotate with a first of two coaxial members and second disks alternating with the first disks and constrained to rotate with the second of the coaxial members. The first and second disks are movable axially relative to the coaxial members. Elastic separators are disposed between the first disks and adapted to urge them away from one another. The elastic separators have an elastic limit which is sufficiently low as to be systematically exceeded on each increase in the closeness of packing of the disks due to progressive wear of the friction surfaces carried by the latter, for at least part of the service life of the friction surfaces.
