ABSTRACT:
Structure of driving unit in a drum type washing machine including a tub mounted inside of a cabinet, a drum mounted inside of the tub, a shaft connected to the drum mounted inside of the tub for transmission of a driving force from a motor to the drum, a front bearing and a rear bearing mounted on an outer circumference of the shaft at opposite end portions thereof respectively, a bearing housing built in a central portion of a rear wall of the tub for supporting the front bearing, a rotor composing the motor together with the rotor, and coupled to the rear end portion of the shaft, a stator fixed to the tub rear wall inward of the rotor to compose the motor together with the rotor, a connector serration coupled to the outer circumference of the shaft in front of the rear bearing and fixed to the rotor, for transmission of a rotating power from the rotor to the shaft, and a bearing bracket fixed to the rear wall of the tub to cover an outside of the rotor and support the rear bearing, thereby reducing noise, repair and power loss, by improving a structure of a driving unit, improving a product reliability, by improving a washing capability, and improving a productivity by improving workability in fabrication of components of the driving unit.
