Abstract
A thermally compliant interface between mechanically coupled components. In one form, there is more than one register fit between joined components such that a primary register fit maintains the desired fit during certain distortion-inducing operating conditions, while a secondary register fit maintains the desired fit during other operating conditions. In a more particular form, the operating conditions may correspond to times when the joined components are in thermal steady state and thermal transition relative to one another, respectively. Other operating conditions may include periods of where the joined components may be exposed to pressure differentials. In an even more particular form, such a thermally compliant interface may be formed between concentrically coupled shafts in a pump, such as a nuclear safety pump.
