Abstract:
A damper for an overhead cable, comprising:a support member having a first end provided with a connecting means for connecting said support member to the overhead cable, and a second end having a support axis extending substantially horizontally when the damper hangs from the overhead cable, the support member further including an axial member mounted along the support axis, a connecting means rigidly connecting said axial member to the second end, the axial member having a plurality of radial arms extending radially from the support axis along a length of said axial member, said radial arms defining substantially V-shaped inner corners therebetween, the axial member further having a plurality of separating shoulders extending within a radial plane substantially perpendicular to said support axis, each of said separating shoulders extending within one of said V-shaped inner corners; a first dampening member having an arm and a weight connected thereto, the arm having an end mounted around the axial member, the end of the arm having an inner cylindrical wall regularly provided with a plurality of cavities corresponding to and cooperating with the V-shaped inner corners of the axial member on a first side of the separating shoulders for limiting a pivotal movement of the first dampening member in both directions; a second dampening member having an arm and a weight connected thereto, the arm having an end mounted around the axial member, the end of the arm having an inner cylindrical wall regularly provided with a plurality of cavities corresponding to and cooperating with the V-shaped inner corners of the axial member on a second side of the separating shoulders for limiting a pivotal movement of the second dampening member in both directions; a plurality of resilient members each located between the V-shaped inner corners of the axial member and the corresponding cavities of the arm of each dampening member for damping in a resilient manner the pivotal movement of the first and second dampening members around the support axis; and restraining means for restraining a movement of the end of the arm of the first and second dampening members along the support axis.
