摘要： A roller assembly for guiding the motion of a circumferentially extending ring in a gas turbine engine, where the roller assembly has a pin and a collar. The pin has a head which engages a rotatable element, which in turn adapts the roller assembly to engage a track and which adapts the roller assembly to receive an external force from the track under operative conditions, causing a reactive force on the rotatable element to resist the external force. A gap formed between a shank of the pin and the collar decreases the bending stresses in the shank in comparison to forces acting on the pin at an end of the collar which engages a support.

摘要： A method for forming a rotor assembly for guiding motion of one circumferentially extending structure with respect to a second structure is disclosed. Various steps of the method are developed and include forming a pin for receiving a rotatable element for the roller assembly. In one particular embodiment the method includes forming the pin with a one-piece head and trapping the rotatable element between the pin and support structure for the pin.

摘要： A housing assembly for a turbine engine has a housing which is adapted to cooperate with an adjacent valve ring assembly. The housing has a plurality of passages for working medium gases which extend radially through the housing and are circumferentially spaced in the housing. The valve ring modulates the flow through the passages. A plurality of flanges extend axially and circumferentially from the housing. Each flange has a track opening which receives a liner and a roller assembly having a bearing surface. The roller assembly in combination with the liner guides the valve ring assembly. The liner and the housing have different physical characteristics, such as a different rate of thermal expansion and different spring rate characteristics which accommodate differences in thermal growth between the liner and the housing.
