Abstract
A rotary machine including a stationary portion and a rotary portion; at least one bearing provided with a stationary ring and a rotary ring, the bearing being mounted between the stationary portion and the rotary portion in order to guide the rotary portion in rotation; and a damper collar interposed between the stationary ring of the bearing and the stationary portion. The damper collar includes a flexible strip having tongues cut out therein, and the flexible strip is shaped into a ring around the stationary ring of the bearing, the shaping of the strip into a ring causing the tongues to move outwards from the collar so that the free edges of the tongues come into contact with the stationary portion.
