Vane arm torque transfer plate

Abstract

A vane arm connection system for a gas turbine engine includes a vane stem having a head with flat contact surfaces; a vane arm having a claw, the claw having opposed arms having inwardly facing surfaces engaging the flat contact surfaces of the head; and a torque transfer member having a body defining an opening for engaging the flat contact surfaces of the head of the vane stem, and at least one arm extending from the body to contact the claw, whereby load from torque is transferred away from the inwardly facing surfaces.

1 . (canceled) 
     
     
         2 . The torque transfer member of  claim 15 , wherein the at least one arm comprises two arms extending away from each other from the edge of the body. 
     
     
         3 . (canceled) 
     
     
         4 . The torque transfer member of  claim 15 , wherein the body further comprises an end surface closing the opening at an end opposite to the two arms, whereby the end surface holds the body in place against movement off of the flat contact surfaces of the head of the vane stem.

         9 . The torque transfer member of  claim 15 , wherein the at least one arm defines a claw contact surface that is perpendicular to the spaced flat sides of the opening. 
     
     
         10 . The torque transfer member of  claim 15 , further comprising a cutout for receiving an anti-rotation tab to prevent rotation during assembly. 
     
     
         11 . The torque transfer member of  claim 10 , wherein the at least one arm comprises two arms extending laterally in opposite directions from one edge of the body, and wherein the cutout is between the two arms. 
     
     
         12 . (canceled) 
     
     
         13 . The torque transfer member of  claim 17 , wherein the at least one arm comprises two arms extending laterally in opposite directions beyond the width of the body. 
     
     
         14 . (canceled) 
     
     
         15 . A torque transfer member for a vane arm connection, comprising a body having an opening with spaced flat sides facing each other for engaging flat contact surfaces of a head of a vane stem, and at least one arm extending laterally from an edge of the body to engage a surface of a claw of a vane arm engaged with the vane stem. 
     
     
         16 . The torque transfer member of  claim 15 , wherein the body and the at least one arm comprise a single piece part of stamped sheet metal. 
     
     
         17 . The torque transfer member of  claim 15 , wherein the body has a width sized to fit between opposed arms of the claw, and wherein the at least one arm extends laterally beyond the width of the body.

         20 . (canceled) 
     
     
         21 . The torque transfer member of  claim 15 , wherein the spaced flat sides of the opening are parallel to each other. 
     
     
         22 . The torque transfer member of  claim 17 , wherein the width of the body is defined by two parallel outwardly facing edge that are also parallel to the spaced flat sides of the opening. 
     
     
         23 . The torque transfer member of  claim 15 , wherein the opening has a long dimension and a short dimension, and wherein the parallel spaced flat sides are arranged along the long dimension.
