摘要：A locking nut assembly including a bearing nut having a plurality of external serrations, a shaft nut having a plurality of external serrations, and a locking collar having a plurality of internal serrations. The bearing nut and the shaft nut are threadedly installed on a shaft assembly having an impeller, a bearing, and a spline adapter installed within the impeller. The plurality of serrations of the bearing nut align with the plurality of serrations of the shaft nut when they are installed on the impeller. The locking collar is installed on the bearing nut and the shaft nut so that the aligned plurality of serrations of the bearing nut and the plurality of serrations of the shaft nut engage the plurality of serrations of the locking collar. The locking collar is retained on the bearing nut and shaft nut by a retaining ring.

主权项：1. A locking nut assembly, comprising: a bearing nut having a first end, a second end, an interior surface having a threaded portion located proximate to the first end and an unthreaded portion located proximate to the second end, an exterior surface extending from the first end to the second end and having a first plurality of serrations, and a locking insert installed within the unthreaded portion; a shaft nut having a first end, a second end opposite the first end of the shaft nut, and a first portion with an exterior surface having a second plurality of serrations; and a locking collar having a first end, a second end opposite the first end of the locking collar, and a first interior portion with an interior surface having a third plurality of serrations; wherein the first plurality of serrations of the bearing nut align with the second plurality of serrations of the shaft nut when the bearing nut and the shaft nut are each in an installed position, and wherein the locking collar is adapted to be installed on the bearing nut and the shaft nut when the bearing nut and the shaft nut are in their installed positions such that the aligned first plurality of serrations of the bearing nut and the second plurality of serrations of the shaft nut engage the third plurality of serrations of the locking collar.
