摘要： A variable gas turbine compressor vane structure includes a gas turbine compressor vane having a vane support at an end thereof, and a case structure having a bearing support disposed to engage the vane support of the gas turbine compressor vane. The bearing support is typically a bearing bushing or a bearing washer. The bearing support is made of a metal skeleton having open-cell porosity extending therethrough, and an infiltrant material such as an organic or a ceramic infiltrated into the porosity of the metal skeleton.

摘要： A variable stator vane assembly and a bushing thereof. The bushing includes a metal bushing body and a wear-resistant coating. The assembly includes a rotatable trunnion and a first metal bushing. The trunnion is capable of being located in a through hole extending between outer and inner surfaces of a compressor casing of a gas turbine engine. The first metal bushing is capable of being located in the through hole proximate the outer surface to surround a first portion of the trunnion when the trunnion is located in the through hole. The first metal bushing and the first portion have wear-resistant coatings which are in mutual contact, apart from any intervening lubricant, when the trunnion and the first metal bushing are located in the through hole and the trunnion is rotating with respect to the first metal bushing.

摘要： A method facilitates assembling a variable vane assembly for a gas turbine engine including a casing and an inner shroud. The method comprises providing at least one variable vane including a radially inner spindle that includes a groove defined therein that has at least one machined face, and coupling the variable vane radially between the casing and the inner shroud such that at least a portion of the radially inner spindle is inserted at least partially through an opening extending radially through the inner shroud. The method also comprises securing the variable vane to the inner shroud by engaging the spindle machined face with a retainer coupled to the inner shroud.

摘要： A trunnion support for a variable-position stator vane in a turbomachine. The stator vane includes an upper trunnion and a lower trunnion to allow the stator vane to be pivoted about a longitudinal axis. The lower trunnion is supported in a bushing that is carried in an opening provided in an annular stator vane carrier ring. The bushing is longitudinally split and is installed in the carrier ring while in a laterally compressed condition so that when installed in the carrier ring the bushing bears against the carrier ring opening in which it is positioned. When the carrier ring material expands with rising temperature, the pre-stress in the bushing will cause it to expand to maintain tight frictional engagement between the bushing and the opening and thereby prevent relative rotation between the bushing and the carrier ring to minimize wear of the carrier ring material.
