Patent ID: 8137071

Claim:
A turbomachine vane damper designed to be housed between a lower inner face of platforms of two adjacent turbomachine vanes and an outer periphery of a rim of a rotor disk on which the vanes are mounted, said damper comprising: a weight including a surface portion which abuts the lower inner face of the platforms of the two adjacent vanes; a flat bearing plate which abuts the outer periphery of the rim; and a spring connecting the weight to the bearing plate, the spring being a leaf joined at a first end to the weight and at a second end to the bearing plate, wherein the weight is made of a composite material, wherein the surface portion forms, when the spring is at rest, an angle of less than 90° with the bearing plate, the angle being determined by the angle between the lower inner face of the platforms and the outer periphery of the rim, and wherein a first hook is provided at a second end of the weight and a second hook is provided at a second end of the bearing plate, the first hook facing upward and cooperating with a transverse rib of the vanes such that a radially inner free end of the transverse rib abuts a groove of the first hook and the second hook cooperating with a downstream edge of the outer periphery of the rim.
