CONTROL LEVER FOR PITCH ANGLE OF BLADE IN TURBOMACHINE

摘要

PROBLEM TO BE SOLVED: To essentially eliminate the risk of failure of a control lever.

SOLUTION: The control lever for a pitch angle of a blade in a turbomachine has a first end part mounted on a blade pivot so as to rotate the blade and a second end part having a cylindrical peg for mounting on a control annulus. The peg is fixed by crimping of one of its end parts in an orifice of the second end part of the lever, and provided with an annular flange to which the second end part of the lever is applied. A stress distribution means is interposed between the second end part of the lever and the crimped end part of the peg.
