ABSTRACT:
A two point mounting assembly for mounting a dynamoelectric machine or motor in a domestic appliance, for example, a washing machine is disclosed as including a motor having front and rear endshields. The front endshield of the motor, through which a motor shaft extends, has mounting ears integrally formed with it. A mounting plate is provided for the washing machine. The plate has a transmission for transmitting power from the motor to a tub and agitator of the washer. The mounting plate includes a yoke sized to support the motor along an endshield ear and yoke arm abutment. The yoke arms have elongated slots formed in them. Bolts having at least partially squared shafts, for attaching the motor to the plate, aid in limiting rotation of the motor after installation. The transmission has a corresponding shaft having a drive pulley mounted to it. The motor shaft has a drive pulley on it. The pulleys have a belt extending between them, on the opposite side of the mounting plate from the transmission and motor arrangement. The mounting system maintains the pulleys in planar relation to maximize power transfer and minimize belt wear. The structure attachment eliminates the need for more than a two point attachment with corresponding savings of material and assembly cost otherwise necessary with other prior art constructions.
