Abstract
Split component to be held in a fixed position on a shaft includes a component member having at least two portions with opposite ends that mate together in sealing engagement, and a plurality of resilient holding segments positioned between the inner surface of the component member and the outer surface of the shaft for holding the component member in a fixed position on the shaft. By compression, the holding segments provide a resiliency-induced resistant force sufficient to prevent movement of the component member in an axial direction and in a circumferential direction relative to the shaft. In a preferred embodiment, each holding segment is a metal spring member extending less than 180.degree. circumferentially around the outer surface of the shaft and having a continuous concave surface directed toward the outer surface of the shaft with gripping edges along opposite sides of the concave surface. A pusher seal assembly having a plurality of resilient holding segments to prevent axial and circumferential movement of a rotatable adaptor relative to a rotatable shaft, and a method for holding a split component in a fixed position on a shaft using a plurality of resilient holding segments, are also provided.
