ABSTRACT:
A mixer gearbox assembly for driving a mixer shaft capable of receiving either a complete electric drive motor on a first face of the gearbox housing for operatively coupling with a first end of a long cross-shaft in the housing, or alternatively a partial electric drive motor on a second face of the gearbox housing for operatively coupling with an opposite end of the cross-shaft. In an alternative configuration for use with only a partial motor, an assembly containing otherwise identical components is provided with a short cross-shaft replacing the long cross-shaft, which short shaft is supported by a single bearing and is colinearly matable only at the outer end thereof with the drive shaft of a partial electric motor. The rotor and short shaft act as a unitary structure when assembled. The alternative configuration can reduce the cost of manufacture of the gearbox assembly through elimination of a motor bearing, a shaft bearing, and a long cross-shaft, and also this configuration eliminates the usual motor pedestal and its coupling, and through use of all other parts identical with those of the alternative-motor assembly.
