Claim 0:
1. A device for damping a rolling bearing, the device comprising:
an annular support; and
a cage extending axially along an axis of revolution, the cage comprising:
a fastening ring,
a ring configured to be mounted on the periphery of the bearing or to form an outer ring of the bearing,
stanchions connecting the ring to the fastening ring, the stanchions extending obliquely with respect to said axis of revolution and being circumferentially spaced apart from one another such that, for each pair of circumferentially contiguous stanchions, the stanchions define an inter-stanchion opening therebetween,
the ring and the annular support forming radially therebetween a fluidic damping cavity capable of forming a circumferential compressed fluid film,
wherein the annular support comprises a plurality of teeth each extending radially through a respective inter-stanchion opening of the cage.
