An assembly for coupling together in a turbofan engine the guide vane (38) and the inner vane shroud (42). The assembly includes a bushing (68) positioned within a shroud port (60) for receiving the inner trunnion (62) of the vane (38). A washer (70) located between the bushing (68) and a trunnion button (64) of the vane (38) provides substantial retaining contact between the bushing (68) and the vane (38). A shroud retainer (74) affixed to the inner surface of the shroud (42) captures the bushing (68) in the shroud port (60). The retainer (74) preferably spans a series of shroud sections (42) for as much as about one-half of the entire circumference of the shroud (42). The combination of the washer (70) and the retainer (74) with significant span reduces movement between the shroud (42) and the vane (38). Wear on the vane trunnion (62) is therefore reduced and maintenance obligations correspondingly reduced. <IMAGE> |
