Patent ID: 6849976

Claim:
A housing structure for geared motors, comprising a stator core, a rotor, a rotating shaft rotated along with the rotor, and first and second housings rotatably supporting the rotating shaft to the stator core, wherein said first housing comprises: a support part functioning to rotatably support a first end of said rotating shaft on the stator core, said support part comprising: a first spherical bearing having a central hole for receiving the first end of the rotating shaft so as to rotatably support said rotating shaft relative to the support part; a first seat part functioning to receive a part of said first spherical bearing; a bearing seat functioning to hold both said first spherical bearing and said first seat part; and a bearing support plate functioning to support said bearing seat and a part of said first spherical bearing; a cylindrical part provided around said support part, and assembled with said stator core while coming into contact with an upper surface of the stator core such that said cylindrical part thus seals the rotating shaft; and a shaft hole functioning to rotatably support an output shaft, said output shaft being included in the motor to be rotated by a gear train housed in a gearbox unit of the first housing, so that the output shaft transmits a rotating force of the rotating shaft to a target device requiring the rotating force.
