Variable stator vane assembly and bushing thereof

A variable stator vane assembly (10). The assembly includes a rotatable trunnion (12) and a first metal bushing (14). The trunnion is capable of being located in a through hole extending between outer and inner surfaces (18 and 20) of a compressor casing (22) of a gas turbine engine (24). The first...

Zusammenfassung:	A variable stator vane assembly (10). The assembly includes a rotatable trunnion (12) and a first metal bushing (14). The trunnion is capable of being located in a through hole extending between outer and inner surfaces (18 and 20) of a compressor casing (22) of a gas turbine engine (24). The first metal bushing is capable of being located in the through hole proximate the outer surface to surround a first portion (26) 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.
