ABSTRACT:
An improved transmission gear box for miniature motor is equipped with a motor-mounted round plate having a number of equally spaced protrusions or recesses disposed on the periphery thereof. The round plate secured to the case of a motor is provided with a round through hole at the center thereof and a pair of symmetric oval-shaped through holes are disposed at each of the opposite sides of the round hole, and a transmission gear set is operationally associated with and supported by the round plate. The shaft of the miniature motor disposed through the central round hole of the round plate is provided with a gear at the top end thereof so as to permit the engagement of the same to the transmission gear set. A cap having a number of corresponding recesses or protrusions disposed at the periphery of the bottom end thereof can be tightly engaged with the round plate. A second round hole having a vertical flanged skirt is disposed at the top of the cap with one rotation shaft of the gear set extended therethrough. The present transmission gear box is characterized in its simple structure and ready assembly to a motor and easy production thereof.
