The invention relates to a system (40) for changing the pitch of the blades of a turbine propeller, each blade (25) being mounted so as to pivot about a pitch axis (A), the system comprising a control device and a connection mechanism (50) connecting the control device to each blade of the propeller, the connection mechanism comprising, for each blade of the propeller:-a coupling (54) for coupling the control device to the blade of the propeller; the coupling has a first end (56) connected to the control device; and-an eccentric (55) having a first end (62) and a second end (59), the first end of the eccentric being connected to the blade to rotate the blade about a pitch axis (A) of the blade, the second end of the eccentric forming a yoke (60), the yoke being connected by a pivoting connection to the second end (58) of the coupling; a yoke (60) of the eccentric is oriented towards a pitch axis (A) of the blade.
本发明涉及一种用于使涡轮机螺旋桨的叶片的桨距改变的系统(40),每个叶片(25)被安装成围绕桨距轴线(A)枢转,该系统包括控制装置和连接机构(50),连接机构将控制装置连接到螺旋桨的每个叶片,对于螺旋桨的每个叶片,连接机构包括:‑联接部(54),联接部具有连接到控制装置的第一端部(56);以及‑偏心部(55),偏心部具有第一端部(62)和第二端部(59),偏心部的第一端部连接到叶片以使叶片围绕叶片的桨距轴线(A)旋转,偏心部的第二端部形成轭部(60),轭部通过枢转连接而连接到联接部的第二端部(58);偏心部的轭部(60)朝向叶片的桨距轴线(A)定向。
