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.
Claims11
Multiple rotating disk assembly comprising two coaxial members, a stack of disks including first disks constrained to rotate with a first of said coaxial members and second disks alternating with said first disks and constrained to rotate with a second of said coaxial members, said first and second disks being movable axially relative to said coaxial members, friction surfaces on transverse sides of at least some of said disks, elastic engagement means for secure axial clamping of said friction surfaces between said disks and elastic separator means disposed between said first disks to urge said first disks away from one another, the clamping force normally exerted by said elastic engagement means exceeding the elastic limit of said elastic separator means so that the force said elastic engagement means has to apply to overcome said elastic separator means remains generally constant regardless of the degree of wear of said friction surface.
