Apparatus for assembling an encapsulated wet motor circulator

Abstract

A method and apparatus are disclosed for assembling a rotor mounted on a shaft and a plurality of bearing support members, each of which includes bearings, within an encapsulated sleeve in precise axial alignment for use in a wet motor circulator. A curable adhesive is applied to a predetermined location on the interior surface of the sleeve determined by the prospective location of a bearing support member therein. The bearing support members are positioned on the shaft on each side of the rotor, and the rotor and bearing support members are fixed as a subassembly in a curing fixture adapted to maintain alignment of the rotor with each of the support members. A curable adhesive is applied to the other bearing support member and the subassembly is axially aligned relative to the sleeve on a common axis in an assembly fixture. The sleeve is forceably ejected from the retaining portion of the assembly fixture to be secured about the subassembly to form the precisely axially aligned encapsulated assembly of components for use in a wet motor circulator. The apparatuses used for performing the assembly steps are also disclosed.
