<p>The impeller hub (12) is provided with an outwardly tapered socket (38) in which is seated a frustoconical extremity (20) of the drive shaft (22), the circumferentiai wall of the extremity having formed therein axially extending grooves (42) alternating with intervening lands (44), and the socket and extremity being dimensioned and shaped in said manner that, in the finally seated relation of the parts, the lands plastically deform the socket wall material which has a lower compressive yield strength than the extremity. …<??>This assembly has a high torque capacity and is especially suitable for use in centrifugal gas compressors designed to operate at relatively high speeds.</p> |
