ABSTRACT:
A centrifugal blower assembly of the type having a finned barrel portion to be driven by a shaft by rotation about a longitudinal axis of rotation has the barrel portion divided longitudinally to provide two separable halves. A central hub assembly for securement of the barrel portion to the shaft similarly is divided in separable portions each carried by a respective barrel half. Split clamps secure the hub assembly portions about the shaft in integral relation with the shaft. End rings extending around the barrel at its ends similarly are split into half-ring portions each carried by a respective barrel half. Tongue-like brackets and associated recesses of the half-ring portions secure them in integral relation about the shaft. The blower assembly may be installed and removed from the shaft without its removal. A method of installation, as for installating the blower assembly into cooler units, is disclosed, involving mounting the blower barrel halves in sequence on the shaft while it remains in place in such a cooler unit.
