Abstract
A temperature-compensating arrangement is provided for a fluid-moving or fluid-powered rotating machine. One or more rotatable inner components in a housing of the machine are supported and restrained by at least one radial load bearing and allowed to float axially as a result of differences in thermal expansion of one or more inner components and the housing. The housing and inner component(s) are made from materials having coefficients of expansion selected to minimize undesired clearance changes and undesired bearing loads that are caused by the differences in thermal expansion of the materials during temperature changes of the machine.
