Abstract

ALIGNMENT AND CENTERING FEATURES FOR FAN ASSEMBLY A fan assembly includes a fan and a fan drive. The fan includes a fan hub located at a fan central axis, and a plurality of fan blades extending outwardly from the fan hub. The fan hub has a fan hub opening at the fan central axis. The fan hub opening is at least partially defined by a plurality of nodes extending radially inwardly toward the fan central axis from the fan hub. The fan drive is installed in the fan hub opening via an interference fit between the plurality of nodes and an outer surface of the fan drive, thus centering the fan drive in the fan hub opening.
