An apparatus and method for maintaining separation of two journal foil bearing assemblies, where each journal foil bearing assembly comprises one or more foils with lugs formed thereon for insertion into axial grooves of a bore, the means comprising a pin for insertion into each groove so that an edge of the lug that is inserted into the groove abuts the pin and is prevented from axially drifting along the bore. The pin provides a broad area along the lug edge so that the lug edge does not cut into the pin.
1. A bearing system supporting a shaft for rotational movement, the bearing system comprising: a first foil bearing assembly for insertion between the shaft and an inner wall of a bore, the first foil bearing assembly comprising one or more foils, each foil curved in an arc around the shaft, each foil having a lug adapted for insertion into an axial groove in the inner wall, the axial groove parallel with a centerline of the bore, wherein the lug constrains the foil from rotational movement about the shaft;a retaining ring for insertion into a retaining ...
