Turbomachine propeller blade setting device

摘要

A device for setting a turbomachine propeller blade is provided. The setting device includes a first disc and a second disc respectively provided with first and second coupling devices, the first and second discs being coaxial; and a system for tilting at least one of the first and second discs with respect to the other. During a tilting of at least one of the first and second discs with respect to the other, the coupling distance of the at least one blade on the first and second discs remains constant, bringing about the rotation of the at least one blade.

1. A device for setting at least one blade of a turbomachine propeller, comprising:
a first disc provided with first coupling means configured to cooperate with at least one first coupling point of said at least one blade for fixation on the first disc; a second disc provided with second coupling means configured to cooperate with at least one second coupling point of said at least one blade for fixation on the second disc, the first and second discs being coaxial; and means of tilting at least one of the first and second discs with respect to the other, the device being configured so that, during a tilting of at least one of the first and second discs with respect to the other, a coupling distance of said at least one blade on the first and second discs, which corresponds to a distance between said at least one first and one second coupling points cooperating respectively with the first and second coupling means, remains constant, bringing about rotation of said at least one blade, the first coupling means and the second coupling means being respectively configured to cooperate with said at least one first and one second coupling points by forming a slide type mechanical link, the means of tilting comprising actuators able to modify an orientation of at least one of the first and second discs with respect to the other and a distance separating the first and second discs, by a translation movement, and the means of tilting comprising a stop for the actuators so as to establish sliding between at least one of the first and second discs and the actuators.
